Oil heating issues?

1irishninja

We recently moved home and the house has oil heating, it has a condensing oil fired boiler but the problem is unless I am doing something wrong takes ages to heat the house.

After half an hour half the radiators are still cold, after an hour most are warm but they are not even that warm, you could easily hold your hand on them without getting burned. Double radiators with only 1 side working and yes I did bleed them all.

I turned the thermostat up to 30c no difference. In my last house which has a regular oil boiler the house was roasting in 30 mins.

Any advice on what the issue could be?

Have you checked the temperature on the boiler? Turn the boiler up to max.

Are the heating pipes hots? If so and your radiators are cold then they may need bleeding for air or they are full of gunk.

If some of the radiators are working and others aren't then they'll need balancing. Close the lockshield valves down to the minimum (not the thermostatic ones) and you should see a difference.

If none of the above works then there is a problem with boiler.

Sounds like the rads are sludged up if only one panel working? System may need flushing, or possible pump issue. NB: turning up the 'stat doesn't make the boiler heat the house any quicker, it just increases the temp at which the system cuts the demand for heat.

We had new oil boiler when we moved. It didn't really work that well. After research, we have now had new radiators and pipes. Within a few minutes house is boiling! It seems the pipes on the old system didn't work well and were not correctly set up anyway.

Start at the boiler - does it get warm, hot or very hot. Assuming that the boiler gets hot then the water should be pumped around the system by the pump. is it running, are the pipes getting hot - trace the heat around the pipework. It does sound as though you've got crud in the plumbing which may need flushing through

as matelodave suggests start from the boiler and follow his sequence
also check the radiator valves, are they thermostat valves ? were they turned off for the summer and now the valve (under the cover has stuck down/low) if so you may have to remove the cover/plastic setting knob, and release the thermostat pin by wigging it in/out
