Save time, money and hassle with our online radiator selector and heat loss calculator

Designed to help you decide the specific radiator size and power required to meet your needs, our innovative Radiator Selector tool makes finding the perfect radiator simple.

Within the tool you’ll find our Heat Loss Calculator, which helps you calculate the BTU (British Thermal Unit) that you require to effectively heat your room. Using this calculator, as well as providing information about which style of radiator you desire and the space you have available, you can instantly find radiators that will suit your needs.

Discover superior radiators in our Radiator Selector tool at Wolseley and make the most of our competitive trade prices, fast home delivery, and free in-branch collection.

If you log in to your online account before using the selector you will be able to view your own personalised trade prices.
