I'm suffering from some confusion regarding the selection of a combi boiler for my house. I have used an online utility to help me size each radiator for the individual rooms (www.radcalcs.com) but the problem seems to be that it doesn't add up to much! Our house is quite small, having 2 bedrooms, a bathroom, a living room and a kitchen. i've figured out the total required BTU's to be about 21200.
I have a few issues with this - firstly does this figure seem a little low? Secondly, at the beginning of my renovation project I bought a Biasi Combi boiler at a really good price - the only problem seems to be that its far too big for the job - 86000 btus maximum output, 37000 BTU minimum output. I presume that if the adjustment for the CH side of things is wound down, then the boilers hot water capacity will be altered wich is potentially bad cos ive got a BIG bath which will take long enough to fill as it is!
To add further complication, i hope to build an extension starting next summer. This would add 2 bedrooms and a dining room to the house so id like to have the capacity to be able to extend the central heating into the new rooms.
Can anyone please advise me on what i can do?!!
Looking forward to a reply........
