glow worm 30ci - losing pressure overnight, leaking from unknown place

[Joe Lawton]

Hi all

complete novice to boilers, just bought my first house and having a few problems

When the heating is on, there are no issues, no pressure loss, no drips, nice and warm. When i use the timer and the heating clicks off overnight, i awake to a cold house and the boiler not coming on due to being low pressure (0.6 bar, always repressured to 1 bar in the morning) This occurs everyday.

I found a leak, hopefully this can be seen in the photo. At first i thought it was coming from the domestic hot water outlet pipe, as this was furred up and wet, but it actually originates from above this. As a rough guide, as you look at the boiler face on, this would be leaking from the back of the boiler toward the left hand side.

Any ideas?

I have just pressurised to 2 bar, flicked the heating on then off, and can now see the drips flowing, ill see how long it takes the pressure to drop.

interestingly most nights the pressure drops, but there is no sign of water, this only seems to happen on some occasions

thanks

You need a gas safe engineer to get inside to get to the bottom of the problem.

Aye, it's beyond DIY I'm afraid.
