Hi

Have a Glow worm Flexicom 30cx-Installed 2010 and regaularly serviced. Last service October 21.

Works fine, with no issues.

However it has started to leak-though never when the house. is occupied.

Went to Scotland over hogmanay for a week and when we returned there had been a leak of water.Not a huge amount, most had been caught in a cooking foil tray (Think chicken in a bag size).

No leak obvious from the boiler though water pressure was lowish (0.8 bar) so I topped up.

Following week we were at home, no problems. heating comes on at 15:00-20:00 then off overnight

Over the last month or so we have been away from the house most weeks for either at least 2-3 nights.
Weather has been variable-sometimes freezing sometimes 6-7 degrees at night.
Boiler is set to 5 degree anti frost temp.

On our return there is evidence of a leak (I put containers under the boiler to catch it). Not a huge amount , maybe a cupful per day we are away.

Took off the cover had a look but could only see pooling of water at the bottom of the boiler-nothing obviuosly leaking.

Thought it may be temperature related so next time we were away I set the thermostat to come one at 11 degree and put it in the same room as the boiler.

Two days away-leak evident when returned.
Any ideas?

Thanks

Good morning. We have a 10 year old Ultracom which now very frequently thinks there's a demand for hot water, even though there isn't, so the boiler kicks into that mode, and sits there heating tap water that isn't going anywhere. Sometimes this happens if a cold tap has been used or the loo...

Hi, Over the past few months, my wife and I have noticed a constant pulsing sound throughout the house which is particularly noisy at night (this could be as a result of us noticing the sound more when there is less environmental noise). Unfortunately, it is severely disrupting our sleep, so we...
