Hi, its a large 3 bed house with 2 reception rooms. Longest radiator is a double 9 foot long. 6 are long, and three are square. Soz, I'm not technical at all.
Hi, can I get opinion on whether you think a combi boiler (Vaillant ecotec pro 28) running 9 radiators in a three bedroomed house would be ok with 15mm copper pipework throughout? My rads don't ever get very hot. Advice would be appreciated. Cheers.
