To feel comfortably warm and happy with your choice of radiator, it’s important to choose one with the right heat output for that space. Of course, we all love sleek radiator designs, styles to match our own tastes with complementary finishes, but the most important consideration when buying a new heating system should always be the BTU output. This result will give you an effective solution with low fuel costs. Once we have this figure, we can easily work out the possible heat loss in each room and give a BTU output, which will show what you need to heat that space efficiently. Height – Length – Width of the room x 4 (use our BTU calculator ( ) for this). The BTU requirement of each room is calculated on the cubic volume of room space: The number of walls (both internal and external)Īs a general rule, the larger the space the more BTU output it will take to heat the room effectively.

The windows how many, double or single glazed, what type of window surround.The rate of heat loss in a room can be affected by: There are two elements to consider when working out ideal room temperature: firstly how warm you want the room and what heat loss might occur in the space. The higher the output, the hotter the appliance will be, whether that’s a heated towel rail ( ) When you are considering what you might need to effectively heat any room in your home, remember to refer to the BTU output.

The BTU status of a radiator will let you know how much heat the item will emit, helping you to work out if it’s going to be enough or too much for your chosen space.

When purchasing an item such as a radiator, you should see a BTU specification featured within the product details. This measurement is common in the UK, used as a standard heat measurement tool, and it is commonly associated with energy, air-conditioning, power and steam. The BTU unit of classification can be found in heaters such as radiators, cooking devices, gas fire pits, and air conditioning systems. If you’re still confused, you could refer to the more traditional Watt (1 Watt of energy = 3.41 BTU’s) This is sometimes hard to imagine, so you could compare it to the energy given off by a single burning match (Source ). Simply put, a single BTU is around 1.06kj (kilojoules). BTU = British Thermal Unit and represents the amount of energy required to heat or cool one lb of water (around a UK pint) by one degree Fahrenheit.
