Is it common for a new boiler to lose pressure?
The most common reasons for a boiler to lose pressure are: Releasing air or water from a radiator when bleeding it. A leak from the appliance or on the system most commonly from radiator valves or system components.
How often is it normal to Repressurise boiler?
Read our guide on how to repressurise your system. 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.
Why is the pressure on my boiler not changing?
There’s a chance the pressure gauge on the front of the boiler is not reading correctly. This is quite dangerous, especially if you are constantly topping up the pressure. It’s likely that this is the case if you top up the pressure and nothing happens (or the pressure changes very little).
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!
When is it safe to top up the boiler pressure?
Provided the pressure stays up, and there are no obvious signs of leaking water, it’s safe to power the boiler back up. After the boiler has run and had the chance to cool down again, check that the pressure hasn’t dropped significantly. Ideally, you shouldn’t need to top up your boiler pressure very often [3].
Is there a leak in a pressurised boiler?
So taking into consideration the above facts, what is your question? There is a leak somewhere.You have a pressurised system,the only way the pressure can drop is through a leak.Just because you cant see it doesnt mean it isnt there
