Why does my central heating not heat the water?
A very common cause of no hot water in the hot tap is that the pilot light has gone out on your boiler. This is required to ignite the gas that heats the water inside the boiler. If your pilot light is out, you’ll need to follow your model’s instructions to ensure you’re relighting the pilot light safely.
What do you do when your hot and you have no water?
If your home has no hot water, turn off the heater first. Then, reset the circuit breaker. If the breaker tripped, your home will receive hot water again after about an hour. A circuit breaker that continues to trip is a bad sign, so hit the reset button.
Why does my central heating not work with hot water?
The issue is that, in order to get central heating, I seem to be required to have the hot water on at the same time. That is, if I turn the heating on using the programmer, it won’t deliver heat through the radiators unless the hot water is also on, as controlled by the programmer.
Is it safe to use hot water with central heating?
Water – Working with hot water and hot pipes comes with a risk of scalding. The water in your central heating circuit is dirty, and contains anti-corrosion and biocidal chemicals.
What happens if there is no hot water in the House?
There are few plumbing problems more disruptive to daily life than having no hot water in the house. Having a bath is off the cards, and probably so too is taking shower. Doing the dishes isn’t an option (unless you have a dishwasher), and who wants to wash their hands in cold water?
How does a central heating and hot water system work?
I have just purchased a new home, and have a question relating to how the Central Heating and Hot Water systems should work. The boiler is a Baxi HE 24 Solo. The programmer is a Honeywell ST6400C. There is a hot water storage tank in the airing cupboard, which I presume is gravity fed from the loft.
Why does my central heating work but no hot water?
A relatively common fault with boilers sees the central heating work with no hot water. In some cases – such as with broken diverter valves – the hot water will only work when the central heating is fired up, whereas in other cases, the hot water will not work at all.

The boiler will still be working perfectly; however, the flow of water between the heat exchange will be reduced. You simply have to run the hot tap at a slower rate than you normally would.
What happens if your central heating is leaking?
Check for leaks. If your central heating is leaking, this will lead to a drop in pressure, along with a loss of water. Besides the problems with your hot water, this may also lead to rot and structural problems if left untreated, so it is worth checking to be sure.
Why is my hot water not working in my shower?
Similarly, if you have a combi boiler and your central heating is not working but your hot water is working then it could be the same root problem. The diverter valve allows a combi boiler to switch between heating your radiators and your hot water, so when you turn on your hot tap, the diverter valve opens and sends hot water to the tap.
