This is because they’re a moving part and can be oscillating between being open or closed many times a day.
However, they are fixable.
If you have no hot water, try turning the heating on..
Will an airlock clear itself?
In a well designed low pressure water pipe system, air should clear naturally even if you run out of water. As the pipe system fills again, the air should naturally rise to the top and be expelled. Air locks happen when the pipe system is not well designed.
Why is my hot water only warm?
Heating elements may also burn out: The most obvious symptom of this problem is if you suddenly notice that the normally hot water coming out of taps has become only warm. When this happens, it’s likely that the top heating element is defective.
Do I need hot water on for central heating?
It only needs to control the heating, as it heats hot water on demand. Hot water is available whenever you turn on the hot water taps and so does not need a cylinder to store it in.
Why are my radiators getting hot when the heating is off?
When a diverter fails or gets blocked with debris, hot water intended for the hot water circuit can get into the radiator circuit. Then the radiators will be hot even though the heat is turned off. You do not have to live with constantly hot radiators. … If you are experiencing this specific issue with your radiators.
How do I know if my boiler thermostat is working?
To confirm that it is most likely a boiler thermostat problem, shut down the system, turn the temperature on your controller down to zero, and do the same with any in-room thermostats if you have them. Turn it on again, but keep your hot water off so you can check the central heating first.
Is a diverter valve expensive?
You’ll come across various models, many of which will provide either heating or hot water, however, a mid-position diverter valve allows you to have heating, hot water and both. They tend to be more expensive but being able to use hot water and keep your radiators warming up is well worth the extra investment.
How do I know if my diverter valve is faulty?
A diverter valve may be faulty if the hot water taps still work while the radiators do not turn on. Another sign of a faulty diverter valve is if you only can only get lukewarm water from your taps.
What does diverter valve look like?
Here is what a diverter valve looks like (Worcester Bosch). The diverter valve on a combi boiler works much like a lock on a canal would. It opens and closes to allow heat up both hot water and the water in the heating system which provides heat to radiators and towel rails.
How do you fix a faulty diverter valve?

Can you have hot water but no heating?
No heating or hot water This issue can be caused by anything from faulty motorised valves, broken system diaphragms and airlocks, to low pressure or a broken thermostat. To determine whether this issue is caused by low pressure, you should check your pressure gauge to see if it is below 1.
Why is my hot water not getting hot?
A water heater that produces no hot water may not be getting power, or it may have a tripped limit switch or one or more failed heating elements. First, check the water heater’s circuit breaker in the service panel to make sure it hasn’t tripped. If the breaker has tripped, switch it off, then switch it back on again.
Why is my hot water tap running cold?
If you have a combi boiler, your hot water is fed by mains pressure, so if you’ve been getting cold water through the hot taps, you can rule out a water blockage or supply cut-off. … If it’s cold when it should be hot, it’s either a boiler problem or a timer problem.
How long should a diverter valve last?
It should also come with a parts and labour guarantee for between 3 – 12 months, although this could depend on the age of your boiler, as some parts may be close to breaking down.
