Title: Bio for heating once again.
Post by: dgs on March 15, 2022, 11:16:47 AM
Just bought a new Central Heating burner this Winter, a Riello 40 Bio. Its been running really well on 75 bio/25 kero. Whereas the old unit would 'complain' on 50% bio. Its lasted about 12 years on a blend so I can't complain.  I must admit I thought the days of making bio for the heating were long gone but with the present situation its now a big saving once again.

The new unit called a 'Riello 40 Bio' is only recommended for 10% bio max, but seems to be fine on 75% so thats what its getting!

I still de-meth and settle this 'type' of bio (it is converted to 90% min)  as leaving the meth/soap/glycerol in the mix means cleaning out the blast tube quite often.

I still pay for my oil but some collections of stuff that is similar looking to used engine oil I pay less for (about 10ppl) this dark oil is fine for the c/h. I rekon this bio costs less than 25ppl to make ( no heating at all used in this process ) and using Julians intermittant mixing method the pump is only on for 8 mins per stage.

So a massive saving on Kerosene which is now about £1.30/litre

How much was the boiler itself?

Just a few quid under £400 from a company in N Ireland, it arrived next day.

did you not think about a waste oil burner running on veg oil?

(I've been tempted myself)

Just looked them up. Look an excellent piece of kit. I run my old Worcester Danesmore on a mix of 50-50 bio filtered veg but the system for house heating is not standard and the burner only needs to be on for 15 min intervals so cleaning the burner etc is not to onerous.

Yes I did Knighty but they can be a bit problematic, just like the ones that burn wmo.

Cheers bud. So that's fitted into an existing boiler unit?

Yes, just fitted straight in.

Bear in mind that it's unlikely that the boiler front and side covers will fit back on as they are deeper and wider than a standard burner. You'll need a compressor unless you get one with the built in compressor but they are very noisy. If the boiler is in your house don't do it, they stink.
The boiler will clog up much sooner on anything other than bio. They only work on CF boilers not condensing type I believe.
I gave up on mine.

Presumably this is the one Knighty mentioned that you are talking about.

Yes, two types, one with and one without built in compressor. The built in type are wider than a standard burner, both types are wider just the compressor type more so. The blast tube is longer and an air solenoid on the rear makes them deeper in depth.
