   Hi not being a plumber can one of you please advise me? We are moving house soon, 3 bedroom, it has 7 rooms in total I have been to, that the boiler output of 30-40,000 btu's is far to low, can anyone advise me on this. The boiler is a gloworm MK11.
   
   
   Cheers for any help

   You need to calculate the heat loss of each room.
   You can purchase a heat loss calculator at most plumbing outlets. It's a Mears Calculator
