Hello All,
I am getting a new boiler fitted shortly. This will be feeding my underfloor heating system and hot water. Each room of the house (bungalow) each has it's own underfloor heating circuit and thermostat. Each thermostat is linked back to a Herz actuator on the underfloor heating manifold so as each room reaches temperature the actuator closes off the particular underfloor heating circuit.
Thus ... 240v from timeclock--------boiler, pump (undefloor), thermostats
then the 240v from the thermostats goes to the actuators
the actuators are closed when the 240v (via thermostat) switches off
The odd thing (well to me) is that when the central heating is on the main pump is never on, this only comes on with the hot water which is wired in the traditional way ---- tank stat----motorised valve-------pump,boiler
The only time the boiler is off when the central heating is on is when the temperature on it's own built-in thermostat is reached. Ideally I would like the room stats to control everything, that is switch off feed to the actuators and switch off the 240v to the pumps and boiler but as it is presently wired that can't be achieved. So, question is how best to achieve it ?
Regards
Gavin
