HIGH BTU RADIATOR FAQs

Does colour affect the High BTU of a Radiator?

Simply, no. There is a negligible difference in output between a white radiator and a black radiator. So, when you are choosing the best colour for your high output radiators, the decision should be led by which colour is best for your interior design.

What is Radiator BTU?

To understand if you need a high BTU radiator, your first need to understand BTU.

BTU stands for British Thermal Units. When referring to radiators, it is the amount of energy required to increase the temperature of a pound of water by 1 degree Fahrenheit.

Each radiator will have a BTU figure which states who many BTU it produces per hour – BTU/hr. The higher the BTU, the more heat output the radiator achieves.

You need to know the BTU of a radiator, but you also need to know the BTU requirements for your room. To evaluate this, use our BTU Heat Loss Calculator. Input the size of your room, the wall construction, the glazing type and area, and other key factors. The BTU calculator will assess your room and provide you with the BTU.

For large rooms and poorly insulated areas, you will need a High BTU Radiator to heat it satisfactorily.

 

Choosing High Output Radiators

As well as checking the BTU rating of a radiator, there are a few tips to help you choose high output radiators.

Generally, the more surface area available to heat, the more heat can be produced. So, a large radiator will have a higher BTU output than a radiator of the same design. However, different designs can create different outputs.

Convector radiators are known for their high-performance because they use convector fins. These zig zag metal structures attached to the panel or panels add to the surface area, thereby increasing the BTU. Plus, with a choice of single panel radiators with one row of fins; double panel radiators with two panels and either one or two rows of fins; and even triple panel radiators with three panels and three rows of fins, convector radiators are engineered to create the best High BTU Radiator for your room.

One of the highest output radiators, because of its increased surface area, is a K3 radiator. A great example of this high BTU radiator is our Softline Compact K3 which comes in 10 sizes. Even the smallest 600x400mm model is a high output radiator with a mighty 3262 BTU/hr. The largest 600x1100mm model products 8697 BTU/hr.

Column Radiators are high output radiators too. As a traditional radiator that has stood the test of time, these period property favourites are known for retaining heat after they have been turned off as well as being high BTU radiators. The colourful column radiators in our Classic Column Collection are superb high-performance radiators. Even the smallest 300x444mm model produces 983 BTU/hr, while the large 750x1870mm is a mighty high output radiator with 10143 BTU/hr

 

Compact High BTU Radiators

If you need a more space-saving option than K3 high output radiators or don’t have the interior design to suit a column radiator, then a more compact high BTU radiator will be a better choice.

The Planar Horizontal Radiator is a modern designer radiator perfect for contemporary homes. Plus, as a Type 22 radiator, it won’t let you down on heat. The smallest model, the 300x200m K2 model produces an incredible 6341 BTU/hr while the extra wide 600x2000mm K2 offers 11,154 BTU/hr.

 

High BTU Vertical Radiators

When you want the latest design trend and high performance, a high BTU vertical radiator is the answer. These stylish radiators are known for their sleek lines, but they can still be high output radiators.

For a high output vertical radiator, try the Softline Plan Vertical. This modern K2 radiator comes in three sizes offering between 5,036 and 755,4 BTU/hr.

Another high BTU vertical radiator to consider is the Vertical Ultra. Available in a huge variety of colours, the Ultra is one of the higher output vertical radiators. The smaller 470x1040mm produces 294 BTU/hr while the larger 670x2040mm creates a respectable 8107 BTU/hr.
