our vast 105 different models of terma heating elements for radiators : professionally curated into 13 collections, so you can match their functionality with your requirements
What is a heating element? A heating element is used as the heat source in an electric towel rail or radiator. It works by heating the water or oil inside the radiator, in the same way an element heats water inside a kettle. Heating elements can a little daunting to a novice but we make it nice and easy for every homeowner to understand - the biggest obstacle homeowners face is selecting the right wattage - for more info on how to select this see our technical guide linked below. Our expertly curated collections filter all 100+ models of heating element we offer by their features, connectivity and functionality.

wattage selection advice
- Choosing the correct wattage heating element is essential for effective and safe performance.
- Electric Only : If you buy a complete electric towel rail from us, the correct wattage of element is provided with it and you do not need to worry about selecting a wattage.
- If pairing an element with another supplier’s towel rail, select an element with a wattage as close as possible to the radiator or towel rail’s central heating (hydronic) output measured in watts.
- If the heat output of your chosen radiator is listed in BTUs only, you can convert this using the formula: BTUs ÷ 3.41 = Watts.
- Selecting a closely matched wattage ensures even heat distribution without overheating.
- Dual Fuel : On our site, every piped central heating towel rail lists the required wattage of element (for dual fuel installations) in the product specifications, so you know the correct wattage and that it is suitable.
electrification advice
- Before electrifying any towel rail or radiator, confirm that the chosen model is suitable for use with a heating element.
- Not all towel rails or radiators are compatible, as internal design and heat circulation affect performance.
- Installing a heating element in an unsuitable radiator may result in failure, which will not be the fault of the element.
installation
- Full installation instructions are provided in the accompanying manual, but here are some useful notes before fitting.
- Never switch on the element in open air — it must be submerged in the heating medium to operate safely. The element has a safety cut-out if it runs dry, so your tradesman should not test it by powering it on before installation.
- Standard cable is 1.5 metres long and can be extended (daisy chained only) or cut to length as needed.
Some filters could not be applied and were reset.
