Electric panel heater thermostat

[robert1980]

Hi all, I have two different models of electric panel heaters in my flat. They are about 10 years old and work well, but they don’t have a thermostat. I switch them on and off manually or program them using an electronic immersion heater timeswitch. I want to install a thermostat that can automatically switch them on and off based on a set temperature and can be controlled remotely via an app. I've seen WiFi thermostats from Tado and Hive, but I believe they are mainly designed for gas boilers and may have a 3-amp limit and I risk burning them? What other options do I have?

Please see the attached pictures.

Thanks in advance

Are you sure there's not a stat built in, what's the make and model of the heaters

One is a Dimplex Monterey MFP075 and the other is a Milano Aruba with a 600W Terma heating element. Even if there were a thermostat, it’s not digial or something I can control with an app

I missed where you mentioned app sorry, most of them stats have volt free contacts which you can use but you need to check there ratings, usually somewhere in the manual, some salus units have 16A res 5A inductive contacts, which is ample for over 1000 watt of any load, other makes may vary

In the main, any thermostat designed for UFH will be rated 16 amps. The problem is where.

The diagram shows opposing likely best place, but often that is rather hard to wire up. In the main radiators, put the thermostat to one side and at bottom, no real option, that's where water goes in so the TRV can hardly go anywhere else.

I was thinking they may have been supplied by the same MCB and so the stat would be connected by breaking in somewhere along the cable route from the CU. As far as the location of the stat. is concerned I would have thought some central location and balance up with each appliance stat.

I have tried many times, OK with water central heating, but the problem is the same, in a word "hysteresis" and how do you stop it. These graphs show what we get and what we want with electric, it is unlikely one can modulate the output, possible, but unlikely, so we have a trade-off, the shorter the mark/space time, the faster the contacts wear out, the slower, the larger the hysteresis.

However, by storing the heat, then the output is more constant, this is the idea of the oil filled radiator, however there is a limit, with mother's old house, she had a bay window, which would catch the morning sun, so wanted the radiator to cool down reasonably fast, to do this I wanted the radiator to also modulate (turn down) so the TRV (thermostatic radiator valve) working fast was important.

So with an electric resistive heat source, ideal would be a device which can cut the wave form like a dimmer switch does, but to get one that can take the power handling would be rather expensive.

I would say a thermostat built into the heater, and use a plug in smart socket to switch on and off.

any one you would reccomend?
