Grant Areona 17kw questions/concerns
Posted by: @daniel@derek-m will have a look at that tomorrow. I do know they were all replaced with Purmo ones I believe as had column cast iron sort of ones before. I know some of them were replaced with larger and in the case of my second sitting room they added another one. Basically all windows in there.
Directly after the valves it goes down to 22mm copper as they just basically cut the boiler out and put this in exactly how the oil boiler was piped. Guy who built the house was apparently a plumber but to be honest I have done better work myself haha. At some point I plan on doing the whole ground floor in underfloor and replacing the glass wool in the joists with kingspan type insulation. Though want to do that in tandem with a new kitchen as the ground floor pipes start in the kitchen. So figure that would be a good time to do it. Looking at the Nuheat pre routed floor boards that just came out. May go with screed as well. Plenty of time to decide though.
Is there a guide on here for doing your own heat loss calculations?
Is the 22mm pipework before it splits for upstairs and downstairs?
There is a heat loss calculation spreadsheet on the MCS website so I believe.
