jayc89 Posted September 7, 2022 Share Posted September 7, 2022 (edited) I'm trying to figure out what to do with our boiler. It was fitted in a room that was originally meant to be our utility room, but our plans have since changed. I had an idea about moving it to a bricked up window opening in our "cupboard under the stairs". Behind this bricked up window is our kitchen. I don't want to route the pipework through the kitchen, and given the cupboard has no outside wall, I'm trying to figure if this is possible and if so, how... The room at the other side of the far wall in this picture is where the boiler currently is. Ideally all pipework could be surface mounted and reconnected, via a service cavity, to existing pipework in that room. I think that should be possible, with relative ease for the gas/water pipework, my concern is the flue.... The boiler is a Baxi Platinum, and it's dimensions are 45 x 76cm. The bricked up window opening is 90 x 95cm. I suspect it would be pretty tight to get the flue connected with enough room below for the gas/water connections. Coupled with this, the top of the window opening is slightly higher than the sloping roof, can a flue be routed below the boiler like that? Hopefully some experts on here can offer some advice.

JohnMo Posted September 9, 2022 Share Posted September 9, 2022 I just had a look at my boiler instructions and it states the flue should run with a slope back towards the boiler. So the flue is always going up hill from the boiler to discharge point. This is to allow the condensation to run back to the boiler. Link to comment Share on other sites More sharing options...

Think this is more to prevent liquid water discharge (some strange regs) as opposed to something the boiler needs to operate well/efficiently.

Temp Posted September 9, 2022 Share Posted September 9, 2022 (edited) See page 20 and 21 of the installation manual. Looks possible if there aren't any openings nearby (I mean if the slope is ok).. https://mediacdn.baxi.co.uk/-/media/websites/baxiuk/files/product-literature/baxi-platinum-combi/baxi_platinum_combi_installation_and_service_manual.pdf Edited September 9, 2022 by Temp 1 Link to comment Share on other sites More sharing options...

I guess it's a should rather than a must... Link to comment Share on other sites More sharing options...
dpmiller Posted September 10, 2022 Share Posted September 10, 2022 better that than acidic condensate dripping and marking whatever's beneath it. 1 Link to comment Share on other sites More sharing options...
TonyT Posted September 10, 2022 Share Posted September 10, 2022 You may need a condensate pump to collect and then pump condensate away. Link to comment Share on other sites More sharing options...
Temp Posted September 10, 2022 Share Posted September 10, 2022 Can you remove a few stones/blocks to lower the boiler? Link to comment Share on other sites More sharing options...
Ferdinand Posted September 10, 2022 Share Posted September 10, 2022 Make sure you consider what you might want to replace it with in the future, and that that can be done without messing all your plumbing and electrics around again. Remember that gas boilers are on the way out over a decade or two. Personally I would consider boxing it in suitably where it is, too. The lattice sheet stuff that rad covers are made out of can be very useful, and can be bought in sheets relatively inexpensively. F Link to comment Share on other sites More sharing options...
