We moved into a newbuild 18 months ago but over the last 2 months the overflow pipe to my boiler (located directly outside the side of the house, not to a drain) constantly drips. This only happens when the "hot water" is activated, and not when "central heating" is activated. The pressure of the system is fine at 1.5 bar (doesn't change) but when the hot water comes on it drips very fast for the whole duration, leading to quite a puddle outside. I know next to nothing about boilers but guess I have a condensing one (Make is Ideal Logic 18) rather than a combi as I have a large hot water storage tank upstairs. This has only happened in the past couple of months and didn't happen before that, so it can't be right. Anyone got any advice what I should do? Many thanks!!
It sounds like you have an unvented domestic hot water system,there should be instructions in your owners pack
on how to regenerate the air bubble in the hot water tank, if not re-post question stating tank make
