Boiler condensate pump problem

timmeh500

Hello

I had a gas combi boiler installed in September (it replaced an electric system). It has a seperate condensate pump (not sure if they all do!) which sits on the floor below the boiler.

It has been working fine until recently and I'm not sure if it's a problem. I could always here the pump coming on now and then but it seems to coming on A LOT more now. e.g. last night it was on about 11 but boiler hadn't been used since the heating went off at 9. It's on so much that it is quite warm to the touch and the cupboard has that warm plastic smell (there's a carbon monoxide detector right next to it so I know it's nothing like that). The heating has been on more but only an extra hour or so longer than previously. Is this something I should get looked at?

Heating on more = more condensation collecting in the trap = more frequent emptying of the contents by the pump system

Given the cold weather in the last few days, the boiler will have been working harder - using more gas and so producing more condensate.

As an aside, most systems don't need a pump. The are mounted high up on walls, so the condensate can drain away by gravity.

Thanks for the replies. Turn out the extraction pipe out of the pump had a kink in to so the pump was coming on all the time to get rid of the water. The boiler shut itself down this morning because of it so had to have the plumber out.
