What is the best pressure for a combi 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.
When should I top up boiler pressure?
If pressure rises by more than 1 bar when the heating is up to temperature then the expansion vessel may require repressurising. This will require a service engineer. The pressure in the system will usually require topping up once or twice a year.
Is high pressure in a combi boiler dangerous?
Is high boiler pressure dangerous? No, it’s not normally dangerous. The heating system is protected by a boiler pressure relief valve (PRV). This boiler pressure valve prevents damage by letting water escape – sometimes via a small pipe through the external wall near the boiler – when there’s too much pressure.
