High output radiators
High Output Radiators – Power where it’s needed
Standard units often fall short in open-plan areas or drafty period properties. Our high output radiators are engineered for maximum warmth, providing a robust solution for spaces that are notoriously hard to heat. These high-performance emitters balance extreme thermal power with sophisticated, modern aesthetics.
As the UK shifts towards sustainability, choosing efficient heat pump radiators is critical. Our collection features energy efficient high output radiators that excel in low-temperature systems. By maximizing surface area through multi-column formats or triple-panel designs, these high BTU radiators keep your home warm while controlling energy costs. We recommend using a BTU calculator to find the best energy efficient radiators for your specific room requirements. Available in over 200 RAL colours at no additional cost, these powerhouses ensure your heating is a standout focal point, not an afterthought.
What is a high output radiator?
A high output radiator is designed to give off more heat than a standard model. This is usually achieved through a larger surface area, deeper panels, column designs, or multiple panels working together.
When do I actually need a high output radiator?
You’ll usually need one in larger rooms, poorly insulated spaces, rooms with high ceilings, or areas with lots of windows. If a standard radiator struggles to warm the room properly, a high output radiator is often the answer.
Are high output radiators more expensive to run?
Not necessarily. Running costs depend on how much heat the room needs, not the radiator style itself. In some cases, a high output radiator heats the room faster and can run for shorter periods, which helps balance out costs.
Do high output radiators heat rooms faster?
Generally, yes. Because they release more heat into the space, they can bring the room up to temperature more quickly, especially in large or draughty rooms.
Are column radiators considered high output radiators?
Often, yes. Column radiators naturally have a large surface area, which allows them to deliver strong heat output. That’s why they’re commonly used in older UK homes and larger rooms.
Can high output radiators work with low-temperature heating or heat pumps?
Yes — and they’re often a good match. Low-temperature systems need larger radiators to deliver enough warmth, and high output designs are well suited to working at lower flow temperatures.
Will a high output radiator take up more space?
Sometimes it will. Higher output often means extra depth, width or height, but there are also slim high-output options available, including vertical and multi-panel designs, for rooms where wall space is limited.
How do I choose the right high output radiator for my room?
Start by working out the room’s BTU requirement, taking insulation and ceiling height into account. From there, choose a radiator that comfortably meets — or slightly exceeds — that figure to avoid underheating.
