Re: {Disarmed} New Remote Controlled Thermostatic Electronic Radiator Valve

[Vargster <vargster@xxxxxxxxx>]

Wayne,

The boiler tests the temperature of the returning water. I.e. the water
leaves the boiler, travels around the house going through the radiators and
returns to the boiler.  As the returning temp approaches the flow
temperature, the boiler modulates (turns down) the burner, putting less
hea=
t
into the water. This 'saves' gas, but the efficiency drops because the
condensing part of the boiler doesn't work when the returning water temp is
too high.

When your thermostat thinks the room is hot enough, it just shuts the whole
boiler down. You should also have a timeclock/controller that tell the
boiler to come on too...
