Part l and range rating boilers

[Dun1758]

Do we have to range rate boilers

 

[Last Plumber]

Only if it's the best thing to do. Why? .

Ideally you should be matching the Heatloss to the boiler size but yes within reason

Combi Boilers will nearly always have a mismatch between HW demand and CH demand, a decent shower requires a 30kw boiler even if one lives in a one bedroom house.
