One For The Oilies.

Warmflow combi. Only been in 6 weeks, not by me, heating timed and hot water constant. Boiler in garage. Worked fine until last week. Now through the night it boils before the high limit kicks in. Hot water sometimes doesnt run hot but cold. Boiler fires on tap opening as it should. The thing was really running hot. Melted the foam insulation on heating flow.



Took some working out but got there in the end.

What do you reckon
