Controlling a Plinth Heater

What is a plinth heater

A plinth or kickspace heater is a type of fan-assisted radiator which is most commonly fitted underneath cupboards in kitchens, where free wall space is often at a premium. It works by having hot water flow through the radiator part whenever the boiler is running, and then when heat is required an electric fan blows the heat from under the cupboard.

2 Ways of controlling a plinth heater

1. Install an Electric Switch, and then have this control a zone valve that would need to be plumbed into the circuit that feeds the plinth heater. This option would also need a Wireless Room Sensor or Room Thermostat to measure the temperature in the room.
2. Wire in an Electric Switch or Electric Relay to the power feed for the plinth heater, and this could be used to power the fan, then you leave the heat running through the unit all of the time (as it is plumbed in without a valve) and the Genius Hub system just controls when to power the fan. Some people do this as it is the cheapest option but it depends on how much heat comes out of the unit when the fan is not running.
   1. Alternatively, A Wireless Room Sensor or Room Thermostat can be used to measure the temperature of the room, and control the plinth heater in the same way as option 1.
