Title: Timer for heating circuit
Post by Godzilla on May 26^th, 2014, 2:19pm

Hello,

I have a 32A heating circuit supplying three 2000W wall heaters, each with a 13A fused wall switch. I'd like to be able to control the timing of the heaters, preferably with a wall timer in the lounge. This would also be located between the consumer unit and the first heater. Does anyone have any recommendations for the most appropriate type of wall timer? A 7 day programmer would be ideal. I'd prefer not to have individual timers for each heater if possible. Thanks

A standard central heating controller, even a programmable room stat.

This timer would control a contactor, the contactor switching your heating load.

You can get contactors that fit into a consumer unit, if you have spare ways:

Or you can get enclosed ones:

As for a timer? Anything like this:

Visiting a wholesaler may be cheaper.
