I have recently bought this house and I am struggling to get the heat on the radiators fire.
Downstairs become very cold in the morning and with the little ones I want the heaters to be on for sometime... There is a hit water tank in the airing cupboard and a valliant ecotec 418 boiler. There is a honeywell programmer next to hot water tank and a Danfoss dialer thermostat in the living room.

Now the dialer is on full and the hot water programmer is set correctly... On certain random days the heaters (once or twice a week) are fired properly but other days there is no heat on the radiators at all.. The hot water however is working fine..

The temperature in the boiler is set to 70 and almost always this go to overrun mode.

Please suggest
