Timeswitches and Programmers

The following timeswitches and programmers are for use on heating only or heating and hot water appliances To control both hot water and heating on an appliance you will need a 2 channel programmer / timeswitch. To control only heating or only hot water you will need a single channel programmer / timeswitch. Generally a normal programmer would be used in conjunction with a room thermostat to control a heating zone or cylinder thermostat to control the hot water circuit, or on its own if no temperature control is required. A programmer works on the ON / OFF Principle.

BTU Calculator

Below is a tool that can enable you to calculate the BTU requirements needed for your room.

There are many factors that affect this calculation including the outdoor temperature, thickness of exterior walls and the quality of insulation installed. You should also ensure you have a boiler that is capable of generating necessary output for all of the radiators in your property.

Our BTU calculator should be used as a guide only, the actual BTU requirements may be slightly different to what our calculator will produce. If you need further help, please contact us.
