Hi
The bungalow I rent had an old boiler in until two years ago.
A new firebird boiler has been fitted. The hot water tank is separate.
I’ve bern looking at fitting a nest thermostat on it and been sussing out the wiring system.. I think!
Anyway, the pump is wired into a 3 pin round plug and socket on the wall and the boiler on a std 3 pin plug and socket beside it. These go back to a std Drayton controller
This boiler has no divert valve and as far as I can make out , when the pump is off ie hot water selected on the programmer, but when the ch is selected the pump comes on, permanently when the ch light is on
I guess that when it is just hot water and the pump is off the pump itself acts like a diverter valve ? And the water goes to the hot water tank by gravity ?
Is this a efficient way to run the boiler ?
So if the wall stat is turned down the pump is going regardless as long as the programmer has ch selected
I’m wanting to have a nest thermostat wired in but wasn’t sure if the boiler is set
