HI. just refitting an end of terrace 2 bed house, I plan on putting 7 rads in which dependent on type will be from 29,000 BTU to 38,000BTU.
Was looking at Vaillant 24 or 28 the outputs seem to be is 78k and 96k respectively.
I understand its bad to buy too big a boiler, even the smallest of these two is double what i need...is there any ratio i should use or rule of thumb for radiator BTU sizes to output of boiler.?
the other question is the Litre per minute output of hot water, is it a simple as more is better? as i want a good shower output
sorry not a plumber /engineer, just an enthusiastic amateur
