Choosing the right radiators plays a big role in keeping your home warm and energy-efficient.
This guide breaks down everything you need to consider, from selecting the perfect size to understanding BTU output. The right radiator doesn't just warm your home — it can lower energy bills and double as a stylish design feature.

Knowing your room size is the starting point. It dictates how much heating power you need, but also physically how much wall space is available.
Rough guide: Small rooms usually only need 1 radiator. Larger rooms (over 6m long) or L-shaped rooms often benefit from 2 smaller radiators to eliminate cold spots.

The calculator gives you the total BTU requirement for the whole room, not necessarily for a single radiator. You can achieve this total using one or multiple radiators.
One radiator: you need a single radiator that meets the total BTU figure on its own. Two or more: divide the total BTU by the number of radiators.
