Flue gas recovery

[thorn]

Does anyone fit many of these. If so what are they like? Have been asked to fit a Vaillant one, main issue seems to be space. It's to go in a Kitchen cupboard so don't think it's going to happen or boiler will be too low to worktop!
thanks

Mainly to comply with new builds I was told. Really expensive and probably won't make it's money back over the life of the boiler

New build to meet required SAP rating is my understanding. In the real world, a load of pish in my opinion.

Better off multi zoning, weather compensation etc over that rubbish

I thought it might be new build orientated, doesnt seem to be too easy to retro fit in most domestic situations, and as mentioned, they seem seriously expensive for the supposed savings

They reckon if you've an a rated boiler then on a small house would take 39 years to pay for itself , or 13 for a large house depending on gas usage, worth a read

Big, ugly, expensive...where do I sign?

First manufacturer to integrate this into a boiler at a reasonable price (if that is even physically or financially possible) will be quids in! Weather compensation seems a lot more cost effective - and less ugly

Not cost effective!!

Logic code has one i think.

Yep, they do, serviced one a few weeks back, new build house, kitchen fitters had out a cupboard around it which stopped the casing come off. Got to love a kitchen fitter!

Can't believe they still get away with that on new builds it's absolute stupidity

Every condensing boiler has flue gas recovery to a certain extent so there can't be more than a few percent to still from flue gases ..

 

[Ermintrude]

The flue gas has to be about 10c hotter that what it's transferring to that's why if you run at 63c u get condensing almost 100% of time.

Cold comes in at 7c so plenary if scope to recover heat from poc
