This should be more than enough to heat an average 3 bed semi.

I would suggest getting a good corgi in to service and re-set the boiler up

Its a cheaper boiler! Whilst there is nothing wrong with it unfortunately people who buy cheap boilers get them installed badly on the cheap.

It may well be sludged up but you will need an experienced engineer to advise you.

Does it seem to be cutting out a lot when it should be heating rads up?
