These electric radiator thermostats or towel rail elements as they are sometimes known as, are used to heat the heating solution in a fluid filled electric designer radiator or electric towel rail.

Eco Design Lot 20 Compliance

It has been written into UK and EU Law that all electric designer radiators should meet strict new energy efficiency guidelines. In 2019, it became illegal to install electric designer radiators that do not meet these guidelines.

This Geyser DYNAMIC is a highly advanced heating element that is Eco Design LOT 20 compliant and when installed in your electric radiator or towel rail, makes your electric radiator or towel rail Eco Design LOT 20 compliant and legal to install and use within the UK and EU.

The accumulation of eco features built into this heating element take this designer electric thermostat past the threshold criteria score for Eco design LOT 20 compliance. Here are the ECO features of this electric heating thermostatic element.

24hr, 7 day a week timer programming

Giving you control and flexibility to heat your space as and when you choose. Allows you to save power when the room does not need to be heated or heated to full temperature.>

Ambient Room Temperature

The most advanced technical change for ECO purposes, elements installed in electric designer radiators must now sense the ambient temperature of the room NOT the internal solution temperature. A backlit digital display allows you to set the target, comfortable, temperature for the room and the radiator will work to maintain that temperature. This prevents over heating of the room and therefore prevents excessive energy use.

Open Window Detection

The Geyser Dynamic heating element senses the sudden drop in temperature when a window is opened and switches off. This is done automatically without any setting changes from the user. The heating element will automatically start heating again towards the pre-set comfort temperature after 30 minutes or once the window is closed. This feature is based on the logical assumption that nobody would want to waste energy heating the outside air via an open window.

Additional Features

This Geyser Dynamic element incorporated into this designer electric radiator has additional features over and above those required for Eco design LOT 20 Compliance. These include 3 x pre-set fixed programs and 1 x flexible settable programs. The digital temperature range can be set between 7°C and 32°C. The heating element is IP44 rated which means it is electrically safe even if accidentally splashed with water. The Geyser Dynamic heating element comes as standard as Class 1 earthed for UK installations. Class 2 for European installations are available on request.

Function Modes

  • Comfort mode - the heating element maintains a comfortable temperature, set by the user.
  • Energy Saving mode - the heating element maintains an ambient temperature, set lower than comfort temperature. This will save energy when a higher temperature isn't required.
  • Antifreeze mode - the heating element maintains the temperature over 7°C.
  • 2hr Boost mode - the heating element activates the heating element for 2 hours, at full heat. At the end of this period, the controller will return to its previously setting. During the 2 hours, (for safety reasons) the ambient temperature cannot go higher than 32°C.
  • Sequence mode - the heating element operates according to a daily program with weekly repetition. The program can be set by the user.
  • Stand-by mode - the heating element is deactivated, but the controller is operative.
  • CE approved
