Calculate Your Needs – BTU

British Thermal Unit or BTU is a traditional unit of heat required to raise the temperature of any space. Understanding the necessary BTU output in your rooms allows you to chose a radiator that perfectly suits your requirements.  Try to select a radiator as close to the calculated number in order to maximise the efficiency and minimise the costs. If the number is too large divide it between a number of radiators to create an accurate heating coverage. The calculator below is a good point of reference, but if you require more advice contact our experts or visit our showroom.

Room Size and Windows

Most houses have double or triple glazing windows these days, however rooms with large windows still need more heating due to the increased energy exchange from glass. taking this into consideration when purchasing radiators can save you time and money, therefore contact our team of experts, or visit our showroom to talk about your requirements.


Metal Type of Your Designer Radiators

Selecting the right metal type for your rooms is pivotal. It gives you greater control over the temperature in your house.  The right metal type allows you to manage if the radiators stay warm for long (cast iron) or emit the heat into the air quickly (copper, aluminium). Depending on the room you might want to use a different metal in order to achieve the best result.
