Total newbie.
Symptoms
- My hot water cylinder is too hot.
- The rads never get really toasty
- The lever on the cylinder diverer value never moves and seem to be floppy - no resistance
- The lever on the heating divertor moves when the heating comes on
---
I'm guessing the diverter valve to the cylinder isn't closing to force the water round the heating circuit and both the cylinder and house circuits are open at the same time, even when I just want heating.
This accounts for the cylinder getting really hot even when the cylinder thermostat has reached its target temp.
I'm guessing the cylinder thermostat isn't the problem because the cylinder diverter valve lever never moves at all even if I turn off the system.
---
Can someone confirm whether I'm on the right track.
Also assuming it is the cylinder valve thats stuffed, do I need to completely replace the valve and/or is there some partial repair I can do, and how do I tell which?
If I can repair this myself then does anyone have info on how?
The Cylinder value is a Danfoss HPA2.
Thanks loads John
