We've just inherited a central heating system in a recently purchased house.
The boiler is a Baxi Solo 18HE and appeared to be a fairly standard setup with 2 header and expansion tanks in the loft and a hot cylinder......
The timer and thermostat controls seem a bit old though (Randall 103e) and Randall TP5.
There is no mention of hot water anywhere on the timer so I reckon it is a single channel device. The thermostat appears to open and close a single 2 port motorised valve. There is an old looking thermostat strapped to the cylinder.
The layout of the pipes from the boiler is like this
BOILER
PUMP--------------VALVE---------------Radiators (flow)
|
------------------------------CYLINDER (flow)
What seems to happen is that with the room CH thermostat set to off the hot water heats up in the cylinder and then is shut down by the cylinder stat. (which turns the boiler off)
But with the room stat set to on then it will heat both CH and HW.....(but what controls the temperature of the HW)
Do I need to have another valve put in attached to a cylinder thermostat?
It seems a bit limited to me
Any advice gratefully accepted
