Hi,

I have recently moved into a new house. It has gas central heating & hot
water. However I am having a problem getting it to come on automatically.

There is no central thermostat - but there are thermostatic valves on every
radiator, and a 'frost-stat' by the boiler itself.

It all comes on and works if left permanently on the 'on' setting, so I know
the boiler and the radiators and hot water actually work. However, if left
to come on and off automatically, on programmed settings, the lights for
heating and hot water light up on the timer, but it is not actually coming
on, and definitely colder than the thermostat temperatures!

Any ideas?
