I have just moved into a newly built house. The CH system is oil-fired
with independent timer circuits for the hot water, upstairs radiators,
and downstairs radiators.
The radiators heat fine but the hot water tank doesn't.
I have read posts on this group from people with similar problems and
the main advice seems to be check the thermostat and the functioning of
I feel a bit thick here, I can't find a thermostat anywhere on the hot
water tank. Should there definitely be one there? If there wasn't would
this explain my problem?
Other bits of info that may be useful
- There are three valves on the water pipes around the tank with an auto
and manual setting. All are in the auto setting. When moved to manual
they give some resistance and will return to auto when released.
- One is on a pipe half way up the tank, if I lock this in manual then
the water gets VERY hot when the heating is on.
- Immersion heater works fine.
