Remote heating thermostat.

My fathers uncle had a room thermostat plugged in the the house sockets which controlled the temperature in that particular room.
It worked by sending a signal back through the house wiring to the boiler.
Where can I get one form?
Have a child on the way and have been told that it is advisable to keep the room temp. between 18 and 21 degrees - haven't got thermostatic valves fitted so was wondering if these sort of things are available?

I'm afraid what you are proposing just isn't possible in the form you think. Any such thermostat would have to send a signal back to a 'device' that controlled the flow of hot water to the rad in your child's room only. It couldn't work by sending a message back to the boiler - this would switch ALL the heat on or off to the whole house.
Your cheapest solution will be to find a plumber to fit you a few thermostatic rad valves (i.e. a mechanical thermostat solution - not electronic).
There were devices around a few years ago that controlled household gadgets using the mains wiring in a house. Most of these have died out because wireless technology has come down so much in price that its far simpler to run a wirelss solution - examples are wireless buglar alarms and wireless bell pushes. But that's still not a good solution to your problem.

Danfoss (and probably many other companies) do a thermoststic radiator valve that can be remotely controlled from a sensor not sited near the radiator, but, as previous answer suggests, this will only control 1 room. Cheers, Andy

Think I'll go with the wireless option - many thanks chaps.
