Folks
This looks really similar to a problem I have at the moment. I'm topping up the water almost every day and last night the pressure dropped below 0.5bar. In a nutshell, i have a gas boiler, Baxi Solo 80 burner. House is ca. 9 years old. Burner regularly serviced so no issues there.
The pressure drops every day on the gauge. No signs anywhere in the house of leaks, so the water must be going somewhere ! How can I tell if the coil is leaking ? Surely I shouldn't have to replace a hot tank so soon ?
Cheers
