How to Buy a Radiator

There’s a lot of factors to consider when buying a radiator. Our guide to buying radiators online walks you through exactly what you need to do.

BTU Calculator

With radiators, the BTU measurement refers to how much energy is required to heat a particular room. The higher the BTU number is, the greater the radiator’s heat output will be. How effective the radiator will be though depends on factors such as the size of the room and how well insulated it is. A radiator’s ability to transfer heat will depend on its material, size and surface area as well as the water temperature within the system.

MARC & EN442: The Facts About Buying a Radiator 

The most crucial element when considering the purchase of a new radiator is the amount of heat it outputs. The radiator has one fundamental job, to provide you with the necessary heat you require for the space you are heating.

For hydronic radiators, which go onto a water-based central heating system, there are a few simple factors that govern output; The temperature of the water when it leaves the boiler/heat source (known as the flow temperature) and the total surface area and amount of material contained within the product that will heat up, and therefore “radiate”.
