Electric Panel Heaters

Electric panel heaters and wall radiators are direct acting heaters, using standard rate electricity to heat a space up quickly by using convection heat, or a combination of radiation and convection heat. Slimline and wall mounted, these heaters provide rapid heat whenever the user needs it.

Choose from a great range of panel heaters, electric wall heaters and flat panel radiators to suit any budget, big or small.

Electric panel heaters and electric wall radiators are a great alternative to traditional options for an energy efficient, fully controllable source of warmth.

To maximise their operational ability, these heaters have:

  • Low thermal inertia, meaning they warm up rapidly in response to immediate heating needs
  • An electronic or gas-filled thermostat, so they avoid room temperature ‘drift’
  • A range of controls, allowing the user to match their heating requirements with their occupancy patterns

Our range of electric wall heaters achieves this by using convection heat, or a combination of radiation and convection, to warm up a space quickly.

This means that the room is warm for the period of time selected and can be held accurately at the temperature required for the duration of occupancy, creating a comfortable environment. And, when the heater is switched off, it reacts just as quickly.

Is one type of direct-acting heater more efficient than another?

There have been many spurious claims of ‘higher efficiency’ in the electric heating market.

The fact is all direct-acting electric panel heaters are 100% efficient at point of use. If electric wall radiators use 1kWh of electricity, 1kW of heat will be transferred into the room for one hour. As the Law of Conservation of Energy dictates:

‘Energy cannot be created or destroyed but can only change from one form to another’.

With that said, all direct-acting products do not operate in the same way. Take a fluid (oil or thermodynamic) filled radiator, for example: the fluid in the radiator will transfer the heat uniformly around the radiator, giving a higher proportion of radiant – as opposed to convected heat – compared to a convector heater. This is useful for certain applications Since the generation efficiency’ is always 100%. It does not allow comparing the energy performance of electric room heaters.”

However, the very small thermal storage capacity of a fluid-filled radiator also results in slow release warmth to the room during start-up and a slightly prolonged release of warmth to the room after switching off.

By comparison, a radiator panel convector or electric radiator heater with no fluid would release heat to the room more quickly during start-up and stop releasing warmth more quickly at ‘switch off’.

Efficient and affordable heating

Electric Panel heaters

Also known as electric heaters, panel heaters are an affordable source of warmth that produce heat through convection. This means they use hot elements to push hot air out around the room to be circulated. These electric wall heaters are a great addition to your main heating system and can provide extra warmth in those areas that need it most.

Electric wall radiators

Electric wall radiators are another hassle-free alternative to central heating and can be used in all areas of your home as a primary system. They generally produce warmth through both convection and radiation, which is more efficient than panel heating.

Both electric panel heaters and electric wall heaters are available in a range of outputs and sizes, so you can find the perfect product based on the requirements of your living room, hallway, kitchen or bedroom.

Here at Alert, we have a range of energy efficient heating solutions that can be quickly installed into your home, whether you’re looking for a primary source or something in addition to your current central system, or even as a temporary backup. If you would like to find out more about the range of oil-free and electric wall heaters and wall radiators we have on offer, or ask any questions, please don’t hesitate to get in touch.
