Hi,
have a Volkera 25E or 35E (would have to check the number to be exact) and its giving a few problems. The system was left unused for about 2 weeks, and though the pressure was low on return, we raised it up to the required 1.5bar.

The water heating is working ok, but the radiator heating is not. These are controlled by a control unit/timer near the water tank. When the radiator heating is set to go on, a Red light comes on on the control unit, which is per normal. However, despite waiting a few mins nothing happens on the radiators and they remain cold.

The water pump is working fine as it kicks in whenever water taps etc are turned on.

Any guidance on what could be the problem gratefully received. As an aside, the water pressure in the taps is pretty low from the cold tap, but is much stronger from the hot tap.

Could there be a problem with the water inlet pressure for the heating part of the boiler ?

thanks
