How do I Repressurise my electric boiler?
Top tip!
- Switch off and allow your boiler to cool.
- Double-check that both ends of the filling loop are securely attached.
- Open both valves, to allow cold mains water into the system (you should hear it)
- Wait for the pressure gauge to read 1.5 bar.
- Close both valves, one after the other.
Why my electric boiler is not working?
First, reset any tripped circuit breaker, and replace any blown fuse. Next, check if power is being supplied to the electric water heating element thermostat. When the water’s not hot enough, the problem can be an undersized water heater, crossed hot and cold connections, or a faulty heating element or thermostat.
Can a leak cause a boiler to lose pressure?
Whether you have an oil or gas, system or combi boiler, pressure loss is usually directly related to a leak. 99% of the time, a boiler losing pressure is a leak. Unless the dial sits at 0 even when topped up there’s a leak somewhere, even if you can’t see it. Boiler Losing Pressure But There is No Leaks ?
What should I do if my boiler pressure keeps dropping?
To fix this, you can pressurise your boiler by topping up the system via the filling loop. However, if your boiler pressure keeps dropping, chances are you may have a leak. Boiler losing pressure – what pressure should my boiler be?
How does a faulty PRV cause a boiler to leak?
A faulty PRV will allow water to exit the system when it shouldn’t. In the event of high pressure, excess water is discharged through the PRV and out of the building via the PRV release pipe. This pipe can be identified outside.
When do you know if your boiler needs to be replaced?
On most digital gauges, you’ll see a flashing pressure reading, if there’s a low (or high) pressure warning. If your boiler pressure reads less than 1 bar, it’s possible that you might have lost water from the system, which needs to be replaced. This is where that filling loop (or filling link) comes in again!
What to do if your boiler loses pressure?
You should never look for leaks inside your boiler, though. Only a Gas Safe engineer should open this. If you do find a leak, or need to top up the water pressure regularly, give one of our engineers a call and they’ll be on-hand to help. If you bled your radiators recently, you may have lost some pressure.

Can a boiler go too low or too high?
Your boiler can either go too low or too high on the pressure scale. Both can cause your boiler to not function properly and to shut down. To find the optimal pressures, consult the manual that came with your boiler. But if that’s lost, most boilers are so similar the pressure differential between them is relatively minor.
