I am thinking of replacing my conventional central heating and hot water system with a gas combination boiler, for my four bedroom extended semi, with one bathroom. My present system is 25 years old, when I did the heating calculations and ended up with a 10kw boiler, which works perfectly well with ample heat output, even in the coldest weather. When I did the heating calcs, the house was *very* well insulated, and I have continued adding insulation/double glazing over the years, so it is now *extremely* well insulated. I am therefore looking for a combi with less than 10kw output to central heating, plus enough say 10l/m to the DHW.
Objective is to save space.
I have looked in Google Groups for old threads, and tried to answer the questions which may be asked.
Kitchen tap gives 16l/m Bath tap hot water gives 9l/min Soft water.
Googleing for combination boilers only gives huge 20+kw models does anyone here know of anything smaller?
As I will now be pressurizing the central heating pipes (copper with Yorkshire fittings) does anyone expect problems with this?
