A resistor in the room thermostat housing
But it's wildly inaccurate. And there seems to be no adjustment for them.
It's a very cheap way to improve the responsiveness of the system. I
once disconnected one, and found out that re-connecting it it made a
noticeable improvement to my comfort in the room with no noticeable
increase in heating costs.
It was a single small room with a blown air calor gas powered heating
system, but the same principle applies to a central heating system as
used in my house.
I think the resistor in this one is making too much heat. It never switches the heating on for very long, and I don't think it's good for a central heating system to be cycled on and off repeatedly. I much prefer it to come on for an hour at a time.
