Why is my Alpha boiler losing pressure?
When the boiler pressure drops to around 0.6bar on the pressure gauge, your Alpha boiler will fail to operate. A sudden drop in pressure is a strong indication that there’s a link somewhere around the heating system. Radiators, various pumps and expansion vessels can all be prone to leaking.
How do I release pressure from my Alpha boiler?

What happens if pressure is too high on boiler?
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.
What causes low boiler pressure?
Causes of low pressure include leaks and recently bled radiators. You can increase the pressure by putting more water into the system via a filling loop. Call a Gas-Safe engineer if the problem isn’t resolved.
How do I reset the pressure on my boiler?
Quote from the video:
Quote from Youtube video: Don't turn any types that are not connected to either end of the filling loop to repressurize the boiler you will need to turn the in laptop. Anti-clockwise.
How long should an alpha boiler last?
Most brands offer around 5 years, with market leaders such as Worcester Bosch offering 10 years.
Does bleeding radiators reduce boiler pressure?
Yes. During the process of bleeding radiators, air is released from within them, which in turn reduces the pressure in your boiler system.
What happens if my boiler pressure is too low?
If the pressure on your boiler is too low, then your central heating may not work, and if it’s too high, then it will be under too much strain and could also be prevented from working.
What happens if boiler has low pressure?
If your boiler pressure drops below the minimum safe pressure, your boiler and central heating will not function efficiently. It will instead spend more energy trying to heat your house with low pressure. Low boiler pressure will not necessarily damage your boiler or central heating system.
How do I increase the pressure on my boiler?
Quote from the video:
Quote from Youtube video: Simply turn one or both tabs 90 degrees. So they're across the pipe. If you accidentally over pressurize the system you'll need to let some pressure out by bleeding a radiator.
What is the correct pressure for a boiler?
between 1 and 1.5 bar
A. The pressure on a boiler should sit between 1 and 1.5 bar. Most manufacturers recommend an optimal working pressure of 1.3 bar.
How do I check my boiler pressure?
To check your boiler’s pressure, you need to locate the pressure gauge on your boiler. If there is the correct amount of pressure in your system, the needle should be between 1 and 2 bar. This area is usually designated in green. Below 1 and greater than 2 is in red, indicating critical zones.
Do I need to turn my boiler off to Repressurise?
It is not necessary to turn the boiler off to repressurise the system. You won’t have to switch off the power to it either. You will need to turn off the central heating, which can be done from the room thermostat, and let the system cool before filling it with more water.
How do I Repressurise my heating system?
Quote from the video:
Quote from Youtube video: So what you've got is two valves. Like this they might have levers or there might be screwdrivers. So you need to turn that Valve around to this in line with the pipe.
How often should you Repressurise boiler?
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.
