Can anyone point me towards an Internet resource which gives information about boiler size to square footage of property for a domestic CH system? Or alternatively comment on the following?
I visited a property today to investigate the CH system not giving out enough heat when it gets really cold. One of the things I found immediately was that the radiators weren't balanced properly (the return valves were full open on all that I checked), so that's one job I've got to do.
However, the CH boiler looks like it's well underspecced for the size of property. It's a Potterton Profile - I didn't think to get the model number but it just looked too puny to deliver the heat required for what is a large property - the property has been extended with an extra floor. Physically it looked like it was the Potterton Profile
40L jobbie:What I'd really like to get information on is what size boiler needs to be installed for a given square footage, if such info is available anywhere.
Clues anyone?
