Why does my Baxi boiler keep cutting out?
Often, there is no need to be too alarmed, as Baxi’s boilers are known to be prone to cutting out. It’s likely that the issue is down the combustion chamber seals, which regularly become loose over time and need replacing.
What temperature should a Baxi boiler run at?
Your boiler controls explained To maximise efficiency, we recommend setting your radiator dial to 75 degrees and your hot water to 60 degrees. Once you’ve got your boiler running at the optimal temperature, you’ll want to set the timer for when you need heating the most.
What should the pressure be on a Baxi combi boiler?
between 1.0 and 2.0 bar
The normal operating pressure for your Baxi boiler is between 1.0 and 2.0 bar. A reading of 1/0 to 1/5 bar is ideal and will ensure that your boiler and central heating are working at maximum efficiency. Should the pressure drop below 1.0 bar, then you’ll need to repressurise your boiler.
How do I know if my expansion vessel is bad?
If you think the vessel has failed, unscrew the plastic cap from the pressurisation valve (it’s like a car tyre valve). Momentarily depress the pin in the valve to release a little pressure. If water comes out of the valve you have a definite expansion vessel fault.
Why does my boiler fire up then cut out?
Your combi boiler firing up then cutting out is nothing to worry about. It is usually the result of its ‘preheat’ function. Basically, it’s a way of ensuring that hot water is ready to be used in the taps throughout your home.
Why does my combi boiler keep turning on and off?
If you have a combi boiler and it turns itself off every now and then, it’s probably the boilers ‘pre-heat’ function. This is perfectly normal and doesn’t indicate a fault with your boiler, your boiler is just turning itself on to pre-heat water so that it’s ready on demand when you need it.
Can I leave my boiler on continuously?
Can I leave my boiler on continuously? You can, but it will cost you more. Once your water reaches a certain temperature, the water heater will turn off. It will turn back on again when the water cools.
How do I reduce the water pressure on my Baxi combi boiler?
The best way to reduce the pressure in your boiler is to bleed the radiators. Before you start, make sure your central heating system is switched off. You’ll need the radiators to be cool enough to handle. Some modern radiators can be bled with a screwdriver.
How do I lower the pressure on my Baxi boiler?
What causes high pressure in boiler?
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.
