We have a Veismann combi boiler, installed in about 2014. The wireless thermostat has recently had new batteries, and the boiler serviced a few weeks ago.
However, even though we are in summer, and temperatures are in the late teens lower twenties, the heating is still coming on. Eg, we came home this afternoon to find it on, even though the thermostat was reading 21C, and it was set to 18.5C. This has been going on for the last few months, intermittently, although we turned the heating off for a while, as it was becoming such an issue.
Pressure just dropped to 1bar after heating went off, although it was higher when the heating was on apparently.
