How can I reduce the pressure in my boiler?
How to reduce your boiler pressure
- Switch off your boiler and wait for the heating system to cool.
- Identify and check the boiler pressure gauge.
- If it’s above 2 bars, you’ll need to reduce the pressure.
- Ensure the filling loop or relief valve is tightly closed.
What kind of boiler does Potterton Puma 80E use?
Potterton Puma 80e Combination Boiler Fault Customer reported that the boiler was locking out and the pressure kept dropping The Potterton Puma 80e and Puma 100e boilers and the Puma 80 and Puma 100 permanent pilot combi boilers all use a similar expansion vessel and 3 bar pressure relief safety valve.
What are the most common problems with Potterton boilers?
The Five Most Common Problems with Potterton Boilers #1 – Boiler Pressure Is Too Low Low boiler pressure is a common problem with all boilers and Potterton boilers are as susceptible to this as any others. If your boiler pressure drops too low, the boiler’s default failsafe mechanism will kick in and the boiler will lockout.
What is the E20 fault code on a Potterton boiler?
The E20 fault code on Potterton boilers, relates to an NTC thermistor issue in your appliance. It’s these thermistors that monitor the flow and return temperature of the water in your heating system, as well as water supplying taps and showers.
Where is the bleed valve on a puma boiler?
The Puma boiler has a small bleed valve which can be used to drop the pressure. It’s fitted on the flow pipe just below the diverter valve assembly. The pressure relief safety valve on this boiler was slowly letting by so we changed it too and then raised the system pressure to just over 1 bar.

Are there any problems with the Potterton boiler?
#1 Problem: Low Boiler Pressure (E119 Fault Code) Low boiler pressure is a very common Potterton boiler problem that occurs in all boilers and not just the Potterton models. If your Potterton boilers pressures drop too low, it will stop working and display the E119 error code.
The Puma boiler has a small bleed valve which can be used to drop the pressure. It’s fitted on the flow pipe just below the diverter valve assembly. The pressure relief safety valve on this boiler was slowly letting by so we changed it too and then raised the system pressure to just over 1 bar.
How do you Drop the pressure on a puma boiler?
Dropping the pressure by draining water from a drain cock may be more effort but it saves changing the safety valve. The Puma boiler has a small bleed valve which can be used to drop the pressure. It’s fitted on the flow pipe just below the diverter valve assembly.
You can easily reduce your boiler pressure by bleeding the radiators. Radiators are usually bled to remove any excess air from the system. This air can cause cold spots in your radiators and might make your heating system less efficient.
What happens when the boiler pressure is too high?
Boiler pressure is controlled by the expansion vessel, the balance of air versus water in your central heating system. Too little air in your expansion vessel and the pressure may become too high. resulting in the water coming out of your pressure relief valve.
What to do if your boiler pressure is above 2 bar?
Locate the filling loop and check the valves are securely closed. Bleed your radiators to release trapped air from your heating system. If the water pressure remains above 2 bar, contact a Gas Safe registered heating engineer as your boiler’s expansion vessel, pressure gauge or filling loop may be faulty.
What’s the difference between water pressure and boiler pressure?
A boiler moderates your central heating and your water, though it is important to remember that boiler pressure and water pressure are two separate things. Boiler pressure refers to the pressure of hot water running in your sealed central heating system, while water pressure is the pressure of the water coming through your taps.
What causes low pressure in a boiler?
Causes of low boiler pressure & how to fix them #1 – A leak in the system. A leak somewhere in your heating system may well be tricky to spot. #2 – Leak in the boiler. Vaillant boiler pressure loss. BAXI boiler pressure loss Ideal boiler pressure loss. 3 key pressure takeaways.
What is the safe pressure for a hot-water-heating system?
The high-limit temperature setting should be around 190 degrees and the standard hot water operating pressure around 20 psi. The pressure gauge on most hot water boiler systems is located on the front of the unit, sometimes near the top.
What should boiler psi be?
All boilers should be equipped with a pressure gauge, a pressure relief valve, and a pressure reducing valve. The pressure gauge indicates the water pressure within the boiler, which should normally be between 12 and 22 psi (83 to 153 kPa).
What is the operating pressure of a boiler?
The standard cold water operating pressure of most U.S. and Canadian hot water boilers is 12 pounds per square inch (psi). If the boiler pressure drops below 12 psi, the valve will allow new water into the unit to bring up the pressure reading.
