Previously we used to get decent HW. Now it's barely hot enough to run a bath. I've measured the temperature and it's a fairly constant 43degC. I believe factory setting is 50degC.
Boiler is firing ok and running continuously while hot tap is running. C/H is working fine. My other half thinks HW is better when C/H is on but I'm not convinced it's much different.
If I turn the TMV to Min, the water comes out cold. As I increase the setting it does get hotter but above 3.5 it makes no noticeable difference. (TMV is graduated Min 1 2 3 4 5 Max)
We have a private water supply which is not hard but it does contain minerals which produce some scale in kettle etc.
Is there anything I can do to diagnose the cause of the problem before calling out an engineer?
Thanks in advance.
