Title: BBB 2015 hot tub
Post by: Head Womble on July 07, 2014, 08:24:15 PM
As some of you know Lynda has requested a hot tub for next years bash,
it's not to be anything shop brought but something built by us lot using our normal scavenging attributes.

The initial thoughts are to run it off the Lister, the Lister providing the heat and the pump.

The tub it's self could be made from hay bales with a liner dropped in.

So has anyone got some other ideas.

Can this be made a sticky please.

I would imagine the liner is the problem getting one big enough

also I got a brand new BnQ £5 pump they were selling many moons ago to donate to the tub and its bubble blower

I was thinking builders plastic sheeting (the thick black stuff) for the liner, or pond liner but that would have to be paid for.

Donated parts so far = 1 x B&Q pump (thanks RM)

I have a spare 10 feet diameter, 26 inches deep inflatable pool. The pool liner is perfectly water tight, it's just the inflatable ring around the top leaks air which causes the pool to fall over but, if we could support it with hay bales then that would be fine. Holds 3500 litres of water although it is circular so maybe not the easiest to support with bales.

I have just ordered an arduino and four temperature sensors for my pool controller (pool temp, air temp, flow and return temps) to monitor the temperature and switch the flow on and off from the pool pump to the heat exchanger when needed. As my pool wont be needed during the BBB, I would be happy to bring it along but would want to take it home after the event.

We could use the lister but will need to put a decent load on it. If it is just idling it will never make enough heat. Ideally we would want around 2.5KW of load on it and even then, without an exhaust heat exchanger, the water jacket will only be giving around 2 to 3KW of heat.
It would need some pretty big pumps to load it to 2.5KW

The alternative is an old oil boiler run on bio (it's what I use every day).
A 15KW or so boiler, a couple of pumps (one for the boiler circuit, one for the pool to heat exchanger circuit), a flat plat heat exchanger, a header tank and some pipe will do it.
Running the pool water through a heat exchanger rather than straight through the boiler will stop any rust staining of the water and a boiler is a far more controllable heat source than the lister.

22mm PEX or copper pipe would seem the easiest material for connecting the boiler/heat exchanger, with 1" flexible pipe more suited for the pool connections.
Filtering would be a good idea too, some 10" housings and filter elements should see to that unless someone fancies building a sand filter.

Some good electrical protection will be needed (not sure of the earthing arrangements on Chugs power in the field) with electric pumps and a big container full of warm water and people. I'm sure Vince could deal with that.

Pool chemicals will also be a good idea considering that quite a few of us will be wanting to pile into it.
NigelB's chemical supplier does pool chemicals so could hopefully supply some chlorine and algaecide.

Having just come in from a dip in my new pool (still a 10" one but 30" deep and complete with a tubular steel frame) which is nice an warm from bio heating, I am more than happy to assist with implementation.

I think Jules idea is about the best. I'm developing a boiler collecting habit, so may be able to provide, unless I've vandalised them all by then.
Builders polythene may work, but a couple of foot of water takes some holding back. The bales would have to be lashed together somehow. I'd be thinking about putting carpet under it, too, to stop any punctures.
A ready made poool would be coool......

huge metal bars pounded into ground behind each bale, plus tie rope round side of bails
 and tonys burner gismo heat HE to get heat in


2 bails high and fit tank connectors to liner at first level with silicon sealer and say 4 a side to blow jets of water for the massage feature

Steve's syphon nozzle and bean can blast tube burner would work well into a boiler instead of the normal burner. That way there is a potential to burn hot liquid glycerol

I didn't go into too much detail in my first post as I wanted imput from others.

We had thought of an M67 heater dropped into a 205 drum with the water being pumped from the tub into the 205, hot water overflowing (through a pipe) back to the tub,
this would get it up to temp quite quickly, but is not a good idea for constant heat.

I heat my tub with the lister. It is loaded at 2kW with the genny and has an exhaust HE. It takes about 12 hours tto get 1200L of water to 40c. Some tubs are heated with a woodburner in the tub! Always fancied one of those.
If a genny could be rigged up to the lister that could run an inline imersion heater and load it up. When hot it could run the pump.
Curtain sides from a lorry might make a liner?

He says he has 19 of them.  Don't suppose anyone is travelling Spilsby (up near Skegness) to Southampton any time?  If I got there in good time on the Friday we'd stand a reasonable chance of getting the pool built and up to temp for Saturday.  I have a suitable pump for the circulation too.

if it's built with straw bails around the outside, and kind of circular, a ratchet strap around the outside would be enough to stop the walls pushing out

do straw bails cost much ?

big ones around the outside and then those smaller ones inside up against them would make nice seats


maybe pour a bag of salt into it too, it'll kill the bugs which float of chunder when he gets in ?

Obviously starting early on such a mission really is down to Chug and Lynda since it's their field and event.  But then it was Lynda that requested the hot tub, so Chug may just have to roll with it to keep the lady in the manner to which she is accustomed ;)

So for the surrounding structure are we proposing bales on end in a circle supported by loading straps?  A circle will be hard to form in a membrane but I do quite like the loading strap idea.

I suspect a square will be easier to implement, but I don't know what forces bales can take.  If only we had an expert :)

We'd also likely need some padding between the membrane and the ground, as a couple of tonnes of water pushing down onto a stone may puncture a membrane.  Any suggestions?  More straw perhaps?

We're thinking of longer event next year as it's the 10th BBB and a possible move to 31st july/1st /2nd august as it's Lynda's 60th B/day!

And the only thing straw isn't good for is dealing with is water, so no straw bales.
I was thinking doing similar to our pentrough (Flume that delivers water to the wheel) at the watermill, it's an old packing case that has been fibreglassed to make it watertight.

I'm also gonna check out the scrapyard to see if anything grabs my eye, a cattle/horse round metal hay feeder or similar round metal vessel is what I'm thinking.

Reading the M67 documentation, it was designed for 32 US Gallon drums, or 120l, which must be why people report a cold zone at the bottom of a 205l drum.

They are 35,000 BTU for smokeless operation up to 132,000 BTU with smoke.  Is that enough for a reasonable sized hot tub?  A quick google has people suggesting 250 - 400 BTU for hot tubs, but they want immediate heat rather than 1.5 hours of setup.

I think that chopped down IBCs pump fed from a 205 with an M67 is ideal, they're cheap or free when the tops are damaged and you could link them if you wanted a larger tubbing area.

if you dig a round hole, you could line it and use that ?

the ground would work pretty well to insulate it (most of the time)

then you'd only need a small wall around it to make it a bit tidier / stop people falling into it... something about 1foot high would do ?


or dig a hole, and use rammed earth (I think that's what it's called? - tyres filled with soil) around the outside to lift it up a bit ?



with a stand to hold it in the right position, a M67 heater could go right in the middle, so nu pumps etc.. would be needed ?

How about a hole for  the foot area, you sit on the edge of the hole, and then sandbags for the back rest and extra level above ground?

I for one am not up for digging a massive hole, they take way too much effort for even a little one :)

Ton builder bag of sand is £40, sandbags are about 20kg per bag so 50 white-woven polypropylene sandbags £20.  Could order more and fill some extra bags with soil if we don't think we'd have enough with sand alone?

Or, alternatively, if enough is dug out then just polypropylene bags filled with the soil for the surrounding wall?

I have an 8000litre plastic water tank I bought on ebay but don't need any more... it's about 7 foot diameter.. (a bit wider than a transit van)

I don't know what temp the plastic is good for, but it should be ok for hot tub temps, especially if we put some sand/support/whatever around the out side ?


only problem is, I won't have room to store it till next year... it's ok where it is for the next couple of months but then I'll need it shifted

I can borrow a trailer if we can relay it down to chug ?

even better, I could cut it down to size a bit first, so it's easier to transport ?


the top has a port hole thingie and a crack in it... but if it was fibreglass'd up it could always make two hot tubs

or... one hot tub and one storage tank, so the water could be pumped out overnight to keep it warm or whatever ?

No worries I'm great at digging, but good idea with the sandbags, I was thinking rammed earth walls, I've done straight ones before but was puzzlin over getting them round.

Also, I've got a cast iron heat exchanger that could go in, or over a burner

you could wrap the whole thing in astrofoil before it goes in the hole, plus i suspect you lose more heat from the surface than to the ground anyway.

as a m67 owner there are a few tips to get it working without blowing your head off. dont use petrol. my runs quite happily on heating oil of red diesel. you do have to get the flue hot first to stop it burning back. i  leave mine for longer than you think before opening the tap. i have mine well tamed and it is living in the coach as a space heater at the moment. have fun.

How about a LWB Land Rover rear body.  Line with old carpet and DPM plastic or just line with glass fibre.

Built in seats.
Space under wheel boxes for pumps etc
Won't corrode
Gets another Land Rover off the road
Could be fitted with a canvas roof or hard top if you want to be posh.
Could be insulated underneath if required
Leave on half the chassis and rear axle and it could be towed around ... wouldn't look amiss being towed behind one of the "Winnebago's" seen at the BBB.

i have run mine on 70% veg oil ok. bit more difficult to start but fine once it is hot. i will try it on bio when i have some, but want to keep the bio for the van. i can get red or heating oil around here easily enough and every litre of bio in the heater is a litre less on the road. i see the bio as being worth 1.38 a ltr and the red being 79p.

will measure it when i next light it. the coach is 85 degrees most of the day and 70 at night so haven't lit it for a while. its not a  lot, i have been lighting it for a couple of hours a day and 5 ltrs lasts around a week. will do some more scienific measurments and let you now. they do work ok as a space heater.  i lined the side with insulative  fire brick and ally tape so most of the heat comes out of the top rather than the sides. don't know how long the thing will last but i have another one anyway. it will work on wood as well.

It says in the manual that you can use them as space heaters, so not exclusively designed to be in water.

Steve at the BBB said he got his nice and toasty hot out of water to burn out the accumulated crap from trying to run in on glycerol.

Have you tried yours on veg, or veg thinned with something?

I assume it will run well on bio.

tried it on  veg mixed with 25% red. works ok. i suspect after a while the welds may crack if you get them too hot. didnt notice the bit in the manual saying you could use them as space heaters. thats good to know.

it's about 8 inches higher than me, so about 7 foot tall (but more in the centre)

and it was a bit wider than the transit van that towed the trailer it was on... so about 7 foot diameter too

that makes the circumference a bit over 21feet... so 7 people would have about 3 foot of space each

I think it's about 5mm thick, but then is has plastic bands around it which are about 10mm thick

the weight of the water should hold it pretty rigid and in shape... but it might be best to add something around the sides too

maybe burry the first foot or so ?


the bottom of the tank part is about 6 inches off the floor, and then there's a honeycomb of plastic under it to support the weight

I think it's slightly conical on the bottom for the taps... but can't quite see in properly so not 100% on that

Post by: J.B. Jagworth on January 28, 2015, 05:19:51 PM
Good project with loads of imaginative ideas mooted. It behoves us to get real if it is to be a success though, so for starters consider the heat input requirement:
2000 kg of water heated from 10 deg C to 30 deg C; delta t = 20
Specific heat of water (from memory) = 4.2 kJ/kg/deg
Heat input = 2000x20x2.4 = 96,000 kJ

My home heating system puts out roughly 40kW of hot gas to a heat exchanger measured at 30% efficiency, so 12kW goes into the water. The burn-time needed would be 96,000/12 = 8,000 sec or 2hr 13 min
To this one should add a bit to account for heat loss from the pool and more than a bit to allow for re-loading the glyc burner a few times. All in all, I reckon half a day should do it.
Perhaps other contending technolgies might try a similar calc (in BTUs if you want to be awkward :-)

Can't see a problem meself, Chug puts a plan together, we arrive, gather over a tea/coffee and discuss how we should go about arranging a meeting to decide when to have a meeting to consider Chug's plan.

There's no point in having a meeting 'til all participants have arrived, that might happen by Sunday morning.

By the time the meetings have taken place,  admin and management appointed,  risk assessments and safe systems have been ironed out, everyone supplied with the correct PPE I reckon it'll be ready for next year.

Are we still thinking of heating it via an M67 sat in a 205 drum, with water being pumped from the tub into the drum and then gravity fed back to the tub.

Whats all this talk of the safety elf, he'll only stop you putting me and Chunder in before adding the vegetables.

If you want lots of bubbles, jacuzzi style, the you need a decent sized pump and the venturi nozzles to suck air into the water flow.

For my pool I have a 300lpm two speed pump (300lpm is top speed) pumping through 1.5" hose to three venturi nozzles.
That fills the surface of a 12' diameter pool with bubbles.

OK chaps, after much deliberation and consultation, here's my plan to contribute to the hot tub heating.

I have an M67 and a steel 205l drum (thanks keef), a coil of copper to act as a heat exchanger, a nice, isolated magnetically coupled pump and garden hose to get water to and from the hot tub.  So we can isolate the pool water from the heated M67 water (and not have to worry about maintaining water level in the M67 if water was to be pumped in and out).

What we will need is some form of footer filter for the hose.

I've got some chlorine tablets and chlorine strips if we want to make sure the pool water is hygienic.

What about the build of the hot tub itself?  Chug's mighty plastic fantastic?

You're gonna need some serious coil and heat input to exceed  heat loss to the ground and atmosphere.

Maybe someone else with another M67?

They're about 65000 BTUs, though can peak at more than double that at the expense of chuffing and soot.
Title: Re: BBB 2015 hot tub
Post by: Head Womble on June 10, 2015, 11:06:34 PM
I was thinking about this today, we need to get the ball rolling as there's not much time left.

Can the M67 be cleaned so no heat exchanger is needed, would solve a lot of problems.
To maintain level in the M67 drum you just pump water into the drum and run the outlet as an overflow.
Title: Re: BBB 2015 hot tub
Post by: Tony on June 11, 2015, 12:05:58 AM
What do you mean by outlet? It would overflow, for sure :)  I considered adding a port to the side but then you need decent plastic waste plumbing for the return, and a suitable height differential - it would mean an elevated platform for the M67 and drum, which doesn't sound too safe.
Title: Re: BBB 2015 hot tub
Post by: Dickjotec on June 11, 2015, 09:02:15 AM
I heat my tub from a 205L tank, heated by either the Lister or a boiler, using a finned heat exchanger from a CH boiler. The HE is under a wooden duck board, held down with some slab cut to shape. This has worked well for a number of years. It raises the temp by about 1 degree an hour. the heat source has to run for less than an hour a day. Pumps etc are controlled from PIDs. Initial heat of the year is boosted with a heater from one of the inflatable tubs I got second hand run from the lister, this gets it up to temp in a day. We run at 37c with the 205 never over 60c, a bigger differential would, of course heat it quicker.
If you go for a tank I would suggest placing your tub on some polystyrene and lagging with bales.
Title: Re: BBB 2015 hot tub
Post by: Tony on June 11, 2015, 02:05:24 PM
Well the copper coil I have is 12mm, I'm not sure how long (I'll have to check, either 5m or 10m) so should heat water nicely enough, the question is flow rate through it and the garden hose (and loss to atmosphere from the hose).  The 205 I'm sure we can get up to 60-80C though with kids around it's probably better to keep it on the lower end, certainly when we start we can bump the temp right up to get things going.
Title: Re: BBB 2015 hot tub
Post by: Dickjotec on June 11, 2015, 04:34:21 PM
My tub, and the house and cabin, is fed through 15mm barrier pipe admittedly underground, and there is very little loss. Circulation with a CH pump and a big height difference.
Title: Re: BBB 2015 hot tub
Post by: Tony on June 11, 2015, 08:49:45 PM
Just checked and the coil I've got is 10m, it's only the flow that is a worry.  Perhaps we need pipe insulation for the hose?
Title: Re: BBB 2015 hot tub
Post by: Dickjotec on June 11, 2015, 10:20:43 PM
Depends on how far the 205 is from the tub. I would not worry if it is up to 15M. The water is not in the pipe long enough to loose much heat to air. I assume a cCH pump is planned for the circulation?

everything's gone to crap here

went to make some phone calls and left a lad moving some stuff around to get the tank out and tidy up a bit in the process... he knocked the forklift into gear as he jumped off it (without putting the hand break on)

forklift drove off and straight into the tank, crushing it against a wall

totally ruined :-(



anyone have any other ideas of a tank ?  I'll collect and bring it down to the BBB no problem

feel really crap after everyone's made plans around this tank :-(

Can't have it too close or the tub will get a layer of soot on it from the M67 if the wind is the wrong way (particularly when it's running full chatter).  I wonder if the wind blows a particular way on average there?

totally ruined :-(

That's a shame but at least no-one got hurt in the incident, could have been a lot lot worse.  We'll just have to find another way.

Those quick set pools (the ones with the inflatable ring around the top) are rubbish. I had one and it didn't last more than a couple of weeks. Some air leaked out of the ring and that is the only thing that holds up the pool. The next thing was a loud woosh as 3000 litres of chlorinated water rushed off down the garden.
That was with very light use and cold water.

We then got a steel framed 10' X 30" pool. That is 1000 times better. It lasted all last season and we have just put it up again now and it's still perfect.
I have that one heated and last year the water got to 40C one day (faulty thermostat).
You can buy them from Amazon for £90 or therabouts for the 10' one.
They also do 12', 15' and 18' diameters and depths up to 48"

I may only get there Friday evening but I'll be staying until Sunday.

So you still have the normal annual Womble bashing opportunity, but sadly (for you) not an extended one.

However I do understand that you don't have that many annual Womble bashing opportunity's left do you, so you need to make the most of the Womble bashing season while you can.

Anyway three days is enough time to play out what ever it is your evil twisted mind can come up with, or you would have thought so anyway, but looking back over the last few years your mind and mouth have written checks that the body just can't cash.

Depending on depth I would have thought that some shuttering ply and 4x2 with ratchet straps to support would be a fast and cheap way to go. Add some styrene or kingspan and it would be well insulated. Line with polythene or butyl.

15 mins from me ... happy to go and pick it up (assuming they don't drop ship from else where), but I'm not planning on getting to the BBB until Saturday morning.

Anyone traversing the Southern section of the M25 on the way to Chugs, prior to that ... I can hold and pass on.

(http://i471.photobucket.com/albums/rr79/julesandtash/Boiler%20and%20thermal%20store/20150621_174931_zpsycyvpujn.jpg)

It is a 10' X 30" bestway. The white pipe going in a funny angle is just temporary while I wait for a few fittings to turn up.
Full to the top it holds about 7500 litres so it's important to make sure it is on a firm and level surface. Mine is on a 20' X 14' steel reinforced concrete pad 4" thick and has 4" of celotex between the pool and the concrete to insulate the warm water from the cold concrete and also make a nice smooth surface to protect the liner.

I will soon be building decking around it to make it blend in a lot more.

This is inside the plant shed,

From the left is old oil boiler (running on bio), expanson vessel for the sealed system boiler loop, high flow cartridge filter, multi-port valve to use or isolate the filter, or divert flow to waste, stainless steel heat exchanger and finally a two speed 1.5HP pump (100litres per minute on low speed, 300litres per minute on high)

At the risk of being shot down in flames ...... Gota admit, it's not really in the spirit of the BBB to buy a ready made pool is it?


What's wrong with straw bales ratchet strapped and lined with visquith/pond liner?


No digging, easy to find the bits and easy to get rid of afterwards.

I would've followed that route too, but straw bales were mooted by Chug earlier above:

And the only thing straw isn't good for is dealing with is water, so no straw bales.

I agree it's not quite the intended spirit to buy a pool, but at least that way something will get done :)

As it rather flies in the face of the original plan and Chug's already commented that Lynda's say's not to buy a pool,  it might be politic to just get the OK from them first.

I know the "buying" bit isn't an issue to all who have offered to contribute, but let's make sure everyone's comfortable with it before we go ahead.

I know he's very busy, but I've PMed Chug and if he and Lynda are happy with us doing this, I'm willing to go and buy it and drive it up to Chugs field.  Unfortunately I have to work on Tuesday, but I can do it Monday or Wednesday which ever suits Chug and Lynda.

The company sells a sheet to go under the pool for £7.99, but I suspect it's just a lump of blue tarp and not very effective.  If this goes ahead, can any one get a piece of old carpet to the field Tuesday or Wednesday?

If you guys do go for an intex or bestway steel framed pool, dont bother with the ground sheet. It is just a round tarp. You could do much better with old carpet, a huge tarp or, if somebody has some, some kingspan/celotex/polystyrene

I have got the solar cover for mine though. To be fair it is just a round sheet of very heavy duty bubblewrap that floats on the water but it is surprisingly effective at trapping the suns heat in the water during the day

I thought I was nominated the BBB health and safety rep.

Full risk assesment carried out, if it does not involve excessive risk you are not allowed to do it.

Method statements are submitted for all activities friday night while drinking Vince's cider, funniest one, which involves outrageous power tools, operator being the earth return path. This not an exhastive list and I may add more conditions for extra hilarity.

I am the first aider although I was thrown off the course for trying to give annie love bites and blowing in the wrong hole.

Don't forget your 5 point PPE:
Hairy Chest
Boxers
Bottle opener
Braising torch with mapp gas or oxy (needed for searing steaks)
Wellies

For ladies and those that have yet to go through puberty Burt Reynolds style chest wigs will be provided.

See if that satisfies him Richard

Thanks Chug.

I've just phoned the company and they won't let me collect it in person for "insurance" reasons.  I even offered to stand out side while they brought it out, but the answer was still no, and they won't take cash anyway.

Even if they sent it by courier we wouldn't get it until Tuesday/Wednesday and they won't deliver to the field, they have to have an address.

I have a couple of jobs to do today so won't be able to peruse it further until tomorrow.  If anybody can locate one close to me, I'm still happy to buy and deliver it, or if some one can find one local to them and arrange it's delivery that would be great.

OK, found one on Gumtree in Paulsgrove near Portsmouth, un-opened for £60, but the woman hasn't answered emails and phone calls, so I don't know if it's still available, but I'll keep trying.

Failing that ToysRus sell them for £99.99.  I could stop off at the Woking branch, if they have them in stock, and buy one en-route.  Would one more person be happy to contribute the additional tenner?

I now have work for both Tuesday and Wednesday, so it will have to be Monday that I take it up to Chugs field ... hope that's OK Chug?  If there's no one there I'll have to hide it somewhere on site.

I've slung out all my cubies.

This is going to sound really anal, and give the Julian bashers a fieldday, the oil container is part of a matching set that stack, seal and pour really well and that I use for storing excess oil.  My other oil is all in stabbed drums which I don't want to put in the car.  The bio is in my anti-glug pourer, nothing terribly special but I'd like to hang on to it.

By Saturday there will surely be some spares cubies kicking around into which I can decant the stuff.

To give you guys an idea, when i set my up last week i filled it with cold water from the tap all the way up to full (7500 litres).
I then started heating it. My system has a 15KW oil boiler heating the main pool flow circuit via a 100000BTU/Hr stainless heat exchanger.
It took about 6hrs running and nearly a whole 25 litre can of biodiesel to get it to a comfy 30C. So plan on a long burn to get it warm

I'm out most of the day tomorrow, but I'll try giving them a ring before I leave to sus out the situation for Monday.  If Woking don't have one, I'll have to check other stores on route ... I think Argos also do them, but parking at their stores isn't usually as convenient as ToysRus.

I have an oil burner that we can probably setup to heat the outside of the drum too.

Can we get a spare steel drum to the field? I also have a burner which we may be able to use.  But the M67 drum is nicely painted and I was planning on insulation wrapping it.

Bad idea Julian, Argos are another 30 quid.

OK, Woking have at least six in stock.

Checking entailed a chap on a cordless phone searching the store for the item based on my description.  There's three reference numbers for it on the website, but he said it was easier and quicker to check the stock on the shelves!

What ever happened to the age of computers?

Anyway I endeavor to make the run tomorrow, Chug where's the safest place to leave it?

Has anyone thought about chemicals for the pool?  If not I can take a bag (or part bag, what ever we have left) of salt up tomorrow.  Probably not as good as chlorine but better than nothing.

Jules are you sure your pool takes 7500l?  Because Intex say the 10 ft one will be 4,485l to 90% of wall height.

That does tally, 10ft is 3.048m diameter (radius 1.524m), height 30 inches which is 0.762m.

volume = pi*1.524*1.524*0.762 = 5.56 cubic meters

Maybe yours is the 12 ft one which comes out at 8 cubic meters?

I've redone the calculations for the smaller water volume, spreadsheet here:

https://docs.google.com/spreadsheets/d/1ynR4Hv8YmHmyJQqYAvt0ltGQHVPrbFkcvo0CgIfH9yw/edit?usp=sharing

Spoiler: 2-8 hours depending on acceptable smoke level from M67, approx 15l biodiesel (will be more with heat loss and running the M67 harder)

Good stuff, but from tests I've done in the past, mains water seems to be a pretty constant 10°C or there abouts after running for a while.
Title: Re: BBB 2015 hot tub
Post by: Tony on June 29, 2015, 10:09:24 AM
That's the beauty of a spreadsheet, enter one number and the rest jigs around :)  (3-11.5 hours, 20l bio)

I took cold water temp as a guesstimate from here:

http://www.zenexenergy.co.uk/Zenex1/index.php?option=com_content&view=article&id=9&Itemid=5&limitstart=1

I'll bring the IR thermometer so we can keep an eye on temps, it'll be fun :)  (In all honesty, I'm looking forward to the process of heating the pool at least as much as the idea of being in it)

The other thing I was wondering - steps and access.  Can't see Lynda vaulting over the edge, so some sort of steps may be in order.

Also, how are we going to minimise mud and grass ingress?

I propose at least a tarp that we keep swept clean as a walkway to the pool, if not a shallow container of some sort to rinse off feet before entering the pool.

Is there anything we can put the pool up on for insulation/protection against sharp things?  Bit of old carpet?
Title: Re: BBB 2015 hot tub
Post by: Julian on June 29, 2015, 10:49:53 AM
I think it will need carpet underneath as a minimum.  If it's big enough it'll solve the mud problem.  A layer of bales would both insulate and protect.

Perhaps a a foot bath (cut down 20 ltr plastic drum) to wash mud off feet before entering.

I'd thought about a ladder. The sides are only 30" so perhaps a step inside and out might do it.  However, I have a spare 4 section fold up ladder I'll deliver today.  I measured it and it's not exactly suitable as is but I'm happy if someone wants to do a cut and bolt job on it to make it fit.

Head Womble said he had insulation for the outside.

It would be cool if we could use the Lister to heat the pool too, though we'd need to make flanges to fit the Lister's ports and need another small electric pump+pipework.

I have 2 arc welders coming from various places around the UK, got a drill etc.. Do don't see fabbing something up being a biggie. Any one that gets there before me speak to Jim or Richard to use them.

The pool, ½ a bag of salt and the ladder are at the field.

I have a large blower ... not sure if it makes enough pressure but I'll try and find it and check it out before Saturday.

Might need to modify the heat calcs. to account for air carrying the heat away!  And no is the answer to your next question.

I picked up a rug today, 5ft x 7ft so that's part of the base area covered. Got a large tarp too. Will be up Thursday morning or Wednesday evening.

Pool delivered to field yesterday ok, cheers Julian.

I have a couple o builders bags of polystyrene and selotex offcuts and got a few old carpets in the veg plot to go underneath, also got a few old ladders we can use to make steps.

Gonna look for a 205 drum today

But after all this if it is a heatwave we might not want it heated if we need to cool off?
Title: Re: BBB 2015 hot tub
Post by: Julian on June 30, 2015, 04:56:44 PM
Just had thought ... when the pool is first filled if several hose pipes can be connected together and laid out in the sun, en-route to the pool, and the water run in slowly, it may give it a few degrees head start.

Or the same thing running in and out of the pool driven by a pump would help a little.

Big thanks to Julian for going well out of his way to collect/deliver and front the money for the pool, my £10 is waiting for you.

I have just over 20L of veg/engine oil/miss fuel ready for pool fuel.

I spoke to Carl (etz250) today and he'll be joining us from Friday.

I dug out the silver bubble wrap today, there's not as much as I thought but I'll bring it along anyway.

Who's made it there so far, are we missing much ?

Yes Julian definitely deserves some thanks for that!

Chug rightly points out that a hot pool in a heatwave might not be as pleasant as a cool pool.

I would just add that a hot pool on a cool evening in the dark is something glorious too. :D

Turn the heat up a couple of hours before the sun goes down, that should be the best of both worlds.

Nice one!  If our calculations are right though then we shouldn't need anywhere near that much, but best to have too much rather than too little :)

4 pm yesterday our 10' inflatable pool was 24'c. Eldest daughter was straight in it from school then was dragged out at 8pm for a shower n bed. They both keep asking if chugs got a hot tub but I told them it got crushed so no. Can't wait to see their faces when they think they've not got their cosies packed.
