Today we offer a wide range of time switches and heating controls for domestic, commercial and industrial use, via our close relationships with the UK & Irelandâs major electrical wholesalers. We are able to supply our products to companies and organisations the length and breadth of the British Isles.

Programmers are a key component of heating control systems. Since many homes are unoccupied for parts of the day, there is little point in heating them if no one is there to benefit. A programmer allows the occupant to specify when the heating comes on to match their lifestyle and their heating requirements.

For many people in the UK, this simply means firing up the heating in the winter months for a couple of hours in the morning, so the house is warm when they wake up, and then firing the heating up again in the evening so the house is warm when they get home until they go to bed.
