Fischer Future Heat clay core - Exclusive Technology

The unique Fischer heating clay core is 40mm in depth and is mixed with 45% aluminium oxide.

This means the clay core can heat up faster than standard 20mm clay core storage heaters. It also means our heaters can retain heat for longer than other similar slimline storage heaters available on the market.The actual input of the clay core is regulated by the room thermostat thereby lifting the core to the required temperature to heat the room. The amount of heat required is dependant on the weather and the desired setting in the room. As the thermostat full controls the clay core, you are in complete control of each room’s temperature. This means you can still benefit from the cheaper electricity rate during the night using economy 7.

This concept of heating has been successfully proven in Germany and Northern Europe where temperatures can be colder than the UK for longer periods.

Improve Comfort Results with Enhanced Convection

Fischer heating clay core is perforated and sits closer to the front panel in comparison to other storage heaters. As such, our heaters are able to distribute more heat into the room through enhanced convection.

This feature improves the heat production from the front, with the difference between the front and back being as high as 30 degrees. Other storage heaters including 2cm clay core heaters, on the other hand, lose heat that is wasted on the back wall.
