What should the pressure be on a Viessmann boiler?
between 1 and 1.5 bar
The pressure of your combi boiler should be between 1 and 1.5 bar. If your pressure reads at less than 1 bar, it’s possible that you have lost water from the system via a leak.
What happens if you run boiler with low pressure?
Is low boiler pressure dangerous? No – the good news is low boiler pressure isn’t dangerous. Sometimes, heating systems have small leaks – a bit like a slow puncture in a tyre. While you might not notice any water escaping, over time the pressure in the system falls until it’s too low.
Why will my boiler not firing up?
A boiler might not ignite due to various possible reasons – insufficient pressure, blockage in the burner, faulty valves, frozen pipes etc. Sometimes, you can fix the problem on your own. In other cases, you don’t have any choice but to call an engineer.

Before calling an engineer, it is worth seeing if you can reset the boiler yourself.
What happens if boiler pressure too high?
If the boiler pressure is too high, there’s an increased chance of leaks developing in the system. But if boiler pressure is too low, the system won’t work as well. So keeping the correct boiler pressure is important to make sure that your system heats your home efficiently.
Should my boiler pressure increase when heating is on?
When you turn the heating on the water in the pipes and radiators heats up and expands. This water expansion causes the pressure to increase in the whole system. So, when the heating is on you should notice the boiler pressure on the gauge to increase slightly but not above 2 bar.
