Radiators play an important role for many when keeping our homes warm and toasty. Yet it’s the actual size of the radiator in each room that’s crucial when ensuring heat is distributed effectively and your energy usage is kept stable.

However, many UK homes have the wrong-sized radiators, in particular oversized radiators. This means an incorrect balance when it comes to heat distribution and energy efficiency.

Selecting the right size radiator for each room in your home will help ensure optimal heating efficiency and comfort in your space. So, at City Plumbing, as the home of heating, we're here to help you with everything you need to know about selecting the right size radiators for your home.

One of the most common methods for determining the size of radiator you need is by calculating the BTU (British Thermal Unit) requirement for the room.

The BTU measurement takes into account the size of the room, the insulation levels, and the desired room temperature. By calculating the BTU, you can easily determine the size of radiator required to heat the room effectively.

To calculate the BTU requirement, you’ll need to have to hand the measurements of each room in which you’re intending to install a radiator in. This will involve taking the width, height and length of each area in meters. 

Once you've got this information, head to the City Plumbing heat loss calculator and add these details, answering a few other questions here regarding the walls, windows, roof, and flooring.

Then, our handy calculator will show you the BTU of your room, helping you better understand what radiator size will work best here for optimal heating efficiency. 

Choosing the right size radiators for your home is essential for maintaining a comfortable and warm living environment. By understanding your heating needs, calculating the BTU requirement, and selecting the right size radiator, you can ensure efficient heating and optimal comfort in your space.
