Electric heaters question..

[xr4x4]

hi,

our place is heated by std 2kw electric heaters.

trouble is there are so uncontrollable..heat output wise.

the built in thermostat has no relation to the room temp and switch off when the room is still cold and keep heating and boil us when the room gets hot.

is there any way the built in thermostat can be replaced for an external one? even rewired for a std room stat?

your thoughts?

thanks

And the make and model of heaters are...........

You could wire the socket which supplies the heater through an apropriately rated room stat, and just leave the heater set to maximum.

Providing you have the room stat set to an average temperature, the room stat will click in and out before the stat on the heater does.

Also, if you only have cheapo convector heaters, it might be worth taking a look at electric radiators.

thanks for your replies.

heaters are newlec NL200TN

cool, so what room stats are ava that can cope with the high rated amps?

Could it be the location of the heater within the room is not letting it get an acurate feel for air temp. eg close to cold wall, draughts from window etc. try moving it first.

OR, if you dont want the missus using them as on/off switches (an issue in our house but no choice as we have thermo rad valves which cant be locked) then fit one of these:

You would need an ugly long flex to use that stat, unless you mount it too low.

A wireless one, that can switch 10 amp or more, would be better as the control box can go adjacent to the heater.
The sensor unit can then be moved as desired.

ok 2000w is 9 amps yes?

so the 10 amp would be ok?

only one problem, which i guess would be ok with the honeywell controller.

these heaters have built in timers, and have a switch with timed, off and manual. so need power all the time to work on timers... (which we do)

also.. they arent cheap are they.. about £100..!!

Might sound a daft question . . . have you considered other, much cheaper to run forms of heating?

And yes, if you wish to use the inbuilt timers, you cannot use an external thermostat without modifying the internal wiring of the heaters.

cool... thanls for that...

cheaper?

we dont have gas btw...

night storage heaters, heat pumps (in increasing order of initial outlay but decreasing order of environmental impact) I would say the running costs to yourself would be about the same for both. Heat pumps (AKA air conditioners) can extract about 4kw of heat for every 1kw inputted. And night storage costs about 1/3 of the cost of your current heating.

If you want to keep the convectors, you can talk to your supplier and get a better tarrif with daytime cheap rates, say eco 10 or 20/20, and run your heaters during mainly the cheap rates.

The sensors that are built in will be sensing the heater temperature, not the room temperature. The easiest way to improve this would be to set the heaters to maximum and then plug them in via plug in thermostats. Assuming of course that the sockets are in a suitable position (ie not behind a sofa or curtain) so that they can sense the room air temperature. Click here for an example of a Plug in Thermostat

hi,

thanks for that.

trouble is they have been wired into fcus, because they the plugs where getting hot and burning the socket.

also i think the stats would still be too close to the heaters.
