I have recently had a Vaillant Eco tec Plus boiler installed and the pressure drops from 1.5 bar to nothing in about10/15 mins.
The engineer who fitted it says that i must have a leak in the system.
OK so the system is set up as such:- Firstly it is a microbore system.
On the 1st floor their is no leak as it would show by wet patch(s) on the cieling.
The ground floor has the microbore in the floor screed. their is no sign of any damp in the floor screed.
The conservatory has 2 rads and they are fed off of the rad in the living room. I know that this is not the ideal way of doing this but it was the only way at the time.
Anyway i contacted my insurance company as i have a "Trace & Access" clause for water leaks.
A nice guy from a company called Munters turned up and with him he had a Thermal Imaging Camera to check for leaks. So i fired up the heating (i had to keep topping it up every 5 mins or so) The camera showed that all the flow and returns in the main ground floor were sound with no leaks.
But in the conservatory their showed a gap in the imaging of the pipes by the camera and the man said that it looked as though that is where the problem lies on the T piece.
Ok so the next thing that i did was to get the conservatory cut off of the system by blanking the flow and return off. So now i know that the consevatory is no longer connected to the system.
Topped the boiler up to 1.5 bar, went round and bled all the rads, topped up the boiler a couple of times and bled the rads again until no air in the system. Now im thinking to myself that the problem is solved but NO, the pressure is still dropping.
My brain has gone into overdrive with this.
The reason that the engineer said i must have a leak on the system is that if we isolate the flow and return valves under the boiler the pressure stays up at 1.5 bar constant whilst only the hot water side is on.
If it helps at all the code F22 flashes when the pressure drops right off.
Any help on this would be great.
Thanks in advance
Cheers Pete
