How many radiators can a 50kw boiler run?
As a rough guide most apartments and smaller houses, with up to 10 radiators will require a 24-25kw boiler. A 28-30kw would be installed for a medium to large 3-4 bed house with up to 15 radiators, and a 33-35kw and a 40kw would be for a large house with anything up to 20 radiators.
Can a boiler be too powerful?
You want the boiler you buy to have enough power to heat all your rooms and supply enough hot water. If your boiler isn’t powerful enough it won’t be able to do this, but if you buy a boiler that’s too powerful you’ll pay more for it than you needed to and might not have optimum energy efficiency.
How do I know if my boiler can handle another radiator?
Check Your Boiler Output Check the output of your boiler to ensure it can handle the extra strain of another radiator being added on. If your boiler is not capable of handling another radiator as it is then any additional load may cause it to fail.

What should the EWT be for a modulating boiler?
Modulating-condensing basics. Films of gas next to the heat exchanger insulate the main exhaust, and films of water films on the water side impede the heat exchange as well. Usually, the entering water temperature (EWT) at the boiler needs to be 125°F to 127°F or lower before condensation occurs on the heat exchanger.
