Apologies if this has been covered before - couldn't see it referred to specifically.
I have just moved into a 5 year old house with a Range Powermax 155 boiler. The boiler has been inactive for approx 9 months. When I pressurised the sytem up to around 1.5 bar (per needle guage) it seemed to work ok, i.e. plenty of hot water. However, the pressure quickly dropped to around 0.5 bar after a shower and then the burner kicked in and pressure increased to around 0.75 bar. As the stored water cooled the pressure again fell to around 0.5 bar. The manual states idle pressure should be around 0.9 - 1.0 bar so I repressurised again to 1.0 bar.
This cycle of hot water use, falling pressure, burner, falling pressure and then repressurising has continued ever since. I also noticed water loss from the bottom of the boiler, saturating the wooden platform and carpet underneath. The cyclinder jacket was saturated but seemed to dry out as I used the system daily.
I called Heateam (£170 callout) to inspect it yesterday and the engineer almost immediately said it was the automatic air vent that was leaking. He replaced the air vent and drained down the system, pressurised the system back up to 1.5 bar. He took a few temperature / electric current readings and said that should fix it. The boiler is still losing pressure and the hot water jacket is getting wet at the bottom again.
Any ideas please?
