The most expensive fireplace mistake is not buying the dear one. It is buying the wrong sized one.
Too small, and it runs flat out all winter and still loses to the draughts. Too big, and you are sweating in a room you cannot sit in with the thing turned down to nothing.
Ceiling height, insulation and window area change the answer more than floor size does. Measure your room, bring the numbers into any of our showrooms, and we will size it properly. Free, no booking needed.
Full sizing guide is on the website under Fireplace Guides.
