Pressure drop on boiler

missile

Hi,

I have a 12 year old Vokera Mynute 20e boiler serving my hot water and central heating system. It looses pressure and I have to top up every 6/8 weeks. I cannot find any leaks. Should I be concerned?


My insurer offered a free leak check and the plumber could not find a leak. He suggested it may be hidden and a suggested leak sealer.

I am not too keen to add sealer and would appreciate your comments. :A

Why not?

I had a new boiler installed - two weeks later the stopped working due to pressure drop half bar. Got it back up, and an engineer attending to an unrelated problem, tightened a nut where liquid oozing out.
Nevertheless, three weeks after the initial problem again pressure down - call Baxi engineer out. He explained that it only needs a small amount to change the pressure - he added the anti-leak solution, though mentioned that it can take a week or two to become fully effective.

Since then - (touch wood) - no problems.

when was your vokera boiler last serviced,not talking about a safety check flue sample but a proper boiler service.
The mynute is a good boiler and worth looking after as long as it has been maintained.

It is serviced once per year
