Hi all
I moved into a property approx 18 months ago and i've had a problem with the central heating where the radiators only get hot if the programmer is set to BOTH central heating and hot water. I've been ignoring it for ages while I got more pressing matters sorted but i've finally reached it on my list of jobs!
The boiler is a Baxi Solo 18HE
The programmer is a Siemens Landis & Staefa RWB2E which has two sliders, one for central heating and one for hot water.
There is a very old room thermostat (not sure of model but it's branded "Satchwell").
If the slider for hot water is "off" and central heating is "on" then the light on the programmer comes on, but nothing happens.
I had a read up on how the system should be working, and found a 2-port motorised valve and pump near the airing cupboard. I thought the problem might lie here.
With the programmer set to heating "on" and hot water "off", I adjusted the room thermostat to the minimum setting, and then checked the motorised valve and the override lever was providing resistance. I then turned the thermostat up to the maximum, and heard a noise from the motorised valve, the lever was now "loose" which I believe means the valve is now open.. but nothing happens at the boiler end... but I guess the motorised valve and thermostat are working ok?
Once I switch the programmer's hot water setting over to "on" the boiler fires up and the radiators start getting hot eventually, although it does seem to take rather a long time (not sure if thats actually a fault or just the performance of the system..). I've bled them and didn't really get much air out of any of the rads.
Any ideas how I can get the heating to work independently greatly appreciated... it should work that way, right?
