    Hi,

    Looking to replace my Dimplex four zone programmer with something a bit smarter (& easier to program). All my electric radiators are in a single zone which his fine and there's no thermostat as such, each radiator can be set 1-9.

    What options do I have on smart programmers and if possible with wifi and therefore programming via an app?

    I read up on Nest and Hive but these say they only work with mechanical central heating systems.

    I don't really need to control the temperature, just the on/off time.
    Thanks in advance.

    There are very few units suitable for central control of electric heaters and of those I have seen, yours is about the best to operate. The problem is that most programmers only have small electrical contacts as they normally switch only an amp or two for control of valves and are not suitable for switching large loads. The programmers for electric heaters have a pilot wire that sends a signal to the heaters so that the switching takes place locally at each heater.

    Ok thanks for the info, it backs up what I thought.

    Seems like the manufacturers are missing a trick with this, there are loads of new homes with all electric heating with tech from the 80s

    Are they one one (or more) dedicated circuits on your consumer unit, or are they just plugged into general sockets?

    As far as I know there's a pilot wire going to each heater, they are on their own circuit and not just plugged in to wall sockets.

    I don't know what signalling is on the pilot wire, it may be more complex than simply voltage/no-voltage, and it's highly unlikely anyone other than Dimplex make anything compatible with it.

    Heat Genius do an electric switch capable of taking a 3kW load, which should be fine for your needs
