Help with oil heating?

1irishninja

We recently moved home, the house has a Grant Vortex condensing oil heating system. Anyway the damn thing seems to take forever to heat up. Even after an hour OK yes the radiators are warm but you can still hold them so not boiling hot.

I have the thermostat in the house set at 25c and on the outside boiler the little dial is set to 3/4.

Any ideas of the issue?

Is the pump working? Have you bled the rads?

Is the boiler getting hot, is the pump running when the thermostat calls for heat. Turning the room stat to 25 won't heat the place any quicker it will just get warmer eventually.

It's the boiler stat that regulates the radiator water temperature and thus how quickly the house heats up - try increasing it . Don't know what 3/4 means - does it go up to 5 or 10. If 10 then it needs to be set to 7-8, if 5 try increasing it to 4

Try following the pipework from the boiler to see if the plumbing gets hot. If it does and the rads stay cool then maybe the valves are stuck closed or there might be crud in the system. Have you any motorised valves in the system - make sure thay are operating correctly.

Rads usually need bleeding when they are warm or hot at the bottom and cold at the top.

Has your system got a pressure gauge - if so it should be reading 1 - 1.5bar, if it isn't then the system might need refilling.
