afternoon all. hoping someone can assist.
Here are the details of the boilder:
Ideal Response 120 - serviced about a year ago
Location: Kitchen - safety expansion outside
house: 2 floors and loft
Problem:
Boiler is losing pressure when central heating is on. I will come in and pressure has dropped to zero. If i fill up to say 1 bar - and put the heating on - pressure will rise to over 3 bar and a puddle of water can be found at the base of the boiler unit. I've just checked the overflow valve outside and this is dripping a fair bit of water whilst the boiler is on.
What I've already checked:
Have looked for obvious leaks - nothing can be found, have floorboards and carpet and therefore can only really look around radiators etc. Checked and bled radiators. no obvious problems.
Note:
The pressure on the boiler keeps if I don't turn on the central heating - i.e just using hot water for showers and hot taps etc. its only when I switch the central heating on that the pressure then drops.
Please help!
Many thanks
