What year/model is it? and does it have the burbling essex 3 litre?

lozzzzzz · « **Reply #155 on:** June 03, 2014, 06:09:01 AM »

Its a 1976 model, so its an SE6. It did have the lovely essex engine, but now has a vauxhall v6 engine from an omega. Hopefully i'll get that to burble soon, but at the moment it idles just above 1000rpm.

Hi again folks. I little advice please.

I'm hoping to be mounting the condensor this weekend and was thinking about the heat exchanger.

I know where it goes and how it helps, but I was wondering:

Do you get some methanol collecting in the heat exchanger?

Does this mean you have to mount it in a certain orientation?

What is a suitable size, is there one you all use?

Would it be worthe getting a bigger one as I have the built in the ability to fit a second heater at some point in the future?

Thanks for any advice you can offer

Flat plate heat ex mounted on my gl, note the incline.

I should have one in centeral stores you can have. It will get meth in it as will the pipe leading to it so mount it so it can drain.
If you want the one in CS let me know and I will see if I do still have it.

Mine's a proprietary, multi tube heat exchanger, but the orientation is similar.

Thank you all that answers the question perfectly.

I would love to have that one Dick, but you have to accept money for it, they seem to cost quite a bit!

Are you soldering these? Are they not soldered in construction? Do you have to be a bit careful when soldering or are they welded construction?

Dickjotec · « **Reply #161 on:** June 04, 2014, 08:36:21 AM »

I will have a look today and let you know. The one I have is stainless and may have screw fittings but they vary, some do some don't, the stainless ones are welded, not seen a soldered one but I stand to be corrected!

I think flat plate heat exchangers are silver soldered.

As found in many combi boilers, they can be threaded, push fit or just a plain face mating with an "O" ring seal.

This is a push fit drilled out to take a 15mm pipe. You need to drill quite accurately as there's very little meat left.

This is a flat face unit, to which I silver soldered some sawn off, 15mm tap connectors.

Finished job.

Pressure test ... someone on the VOD said it couldn't be done. It's nice showing naysayers they're wrong!

They claimed that the plates would become unsoldered if you tried silver soldering connections, but wrapoping in wet rags and working quickly to reduce heat transfer worked well.

Lozzzz I have 2 you can choose from, both stainless one flat plate one tube with a variety of fittings.

J nice to see a vernier surface gauge in the background, I hope that is not the surface plate being used as a bench!

Julian · « **Reply #164 on:** June 04, 2014, 11:06:21 AM »

No, surface plate is stored safely under the bench, but I have to admit I very rarely use it these days.
