How do I get more hot water pressure from my combi boiler?
Unlike conventional boiler systems, it is not possible to install a boiler pump to increase water pressure because a combi boiler must take water directly from the mains. It is always important to make sure that the boiler is good enough to support a steady and strong flow of water throughout the home.
How do I increase the water pressure in my gas boiler?
Locate the filling loop, often found on the underside of your boiler. Open both valves to allow water into your heating system. Keep an eye on the pressure gauge and close the valves when the pressure reaches 1.5 bar. Switch on your boiler and reset the fault code (if necessary).
How do you make a strong shower with a combi boiler?
Can you have a power shower with a combi boiler? In short, no you can’t. Power showers operate with an in-built pump that makes them incompatible with combi boilers, and they need to be connected to a hot water cylinder – which is a feature that combi boiler systems don’t have.
Why has my hot water pressure dropped combi boiler?
Your combi boiler can be losing pressure for a number of reasons. Pressure loss may be caused from a leak in the pressure relief valve, an issue in the expansion vessel, air in your system, or a leak in the heating pipework itself.
Where is the pump on a combi boiler?
Circulating pumps are usually located inside or near your boiler, especially in combi boiler systems. Alternatively, it may be located in an airing cupboard next to the hot water cylinder, as is typical of non-combi systems.
Can I increase hot water pressure?
A quick and easy way to increase water pressure is to adjust the pressure-reducing valve, which can be found on the main water-supply pipe; look for a conical-shaped valve next to the water meter, close to where the main water pipe enters the house. Protruding from the top of the valve is a threaded bolt.
What mains water pressure do I need for a combi boiler?
between 1.5 bar and 2.0 bar
The normal operating pressure for a combi boiler is between 1.5 bar and 2.0 bar of pressure. Problems can arise if your water pressure drops below or exceeds this boundary.
How do you fix a low water pressure on a boiler?
Quote from the video:
Quote from Youtube video: And close both valves switch the boiler back on and press the reset. Button some boilers start automatically. So check your guide to see if you need to reset yours undo both ends of the thinning loop.
How often should you top up a combi boiler?
The pressure in the system will usually require topping up once or twice a year. If you are having to repressurise your heating system much more frequently, please contact your installer.
Will bleeding radiators increase 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 causes low hot water pressure?
The cause of your low hot water pressure could be debris and sediment in showerheads and taps, water leaks, blocked filters, a faulty tempering valve or something else.
How do I increase hot water pressure in my house?
Look on the main supply pipe near your water meter for a conical valve that has a bolt sticking out of the cone. To raise pressure, turn the bolt clockwise after loosening its locknut. Keep an eye on the gauge to make sure the pressure is within bounds, then retighten the locknut.
Does a combi boiler have 2 pumps?
This usually means that, if your area has low mains pressure, it’s advised that you have a conventional boiler instead of a combi. Equally, a combi boiler doesn’t need an external pump to heat the radiators as the boiler has a pump that does this internally.
Do combi boilers have a built in pump?
On the central heating side, combi boilers pump the water round the heating system in a completely sealed system.
How can I make my combi shower more powerful?
You can boost showers or taps in your home up to the maximimum capacity of your combi boiler. To boost and protect a single shower the best solution is to boost the hot and the cold with the SP22S (gives you two automatic pumps). Each shower or tap you boost and protect needs an extra SP22S.
Does boiler pressure affect hot water pressure?
Does low boiler pressure affect hot water? If you find that your hot water isn’t as warm as it should it be, it may be because your low boiler pressure is affecting your hot water temperature. The pressure of your boiler should be around 1.5 bar.
What is a good hot water flow rate for a combi boiler?
Combi boilers need at least 10 litres per minute flow rate to operate. If you have less then you’ll either need a mains pump (which can increase it to 12 litres per minute) or a pressure accumulator tank.
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.

Is 3 bar too high in boiler?
High boiler pressure isn’t dangerous, even if it’s showing as three bar on the pressure gauge. In most cases, the boiler will turn itself off if the pressure goes about a certain level and a working PRV should successfully control the pressure, preventing it from getting too high.
How do you bleed a radiator with a combi boiler?
How do I bleed my radiators?
- Turn up your combi boiler to the highest heat setting. …
- Check each radiator for cold spots. …
- Turn off your combi boiler. …
- Set up the area for the radiator you’re bleeding. …
- Place your radiator bleed key and start bleeding. …
- Turn your heating back on. …
- Check your pressure gauge.
Do you need to bleed a combi boiler?
You can bleed radiators yourself if you have a combi boiler, but be aware that sealed central heating systems like those with a combi boiler need to be re-pressurised after bleeding radiators. This is done with a lever or valve located near the water supply to the boiler.
Do you bleed radiators with boiler on or off?
Should I be bleeding radiators hot or cold? Always make sure your central heating system (your boiler) is turned off and your radiators are cold before attempting to bleed them. When turned on, your radiators contain hot water, and you could be at risk of scalding yourself if you bleed them at this time.
