What to Check if You Have No Hot Water

In our everyday life, we sometimes take hot water for granted, especially during winter months. If you have no hot water during the winter season, you’ll be surrounded by the cold, which could have an impact on your health. Therefore, it’s important to fix this problem as soon as possible. This is what you should check if you have no hot water.

Check if your boiler is working

The first thing you should do if you have no hot water is to check if your boiler is working. You should look out for any error codes and a change in the colour display, but this will depend on the type of boiler you have. Your boiler manual should then help you to figure out the meaning of any error code. If you find out that your boiler is the source of the problem, it can be easily fixed by resetting it. Boiler Guide has a section focusing on how to reset your boiler. However, if you need a professional, you can take a look at our list of plumbers here.

Check if your water, gas and electricity supply is working

If you find that your boiler isn’t displaying anything, you might have problems with your power supply. You can check to see if this is the case if you have no electricity flowing to your lights and sockets. Incidents like a power cut can affect your boiler, so it’s also important to check your main fuse box to make sure you have electricity.

To determine if the problem is with your water supply, check your taps to see if there is any water running. If there’s no water, there may be an interruption with your water supply. To find out if the problem lies with your gas supply, you can check to see if any gas appliances you have are working, such as your gas cooker if you have one.

Check your clock and timer 

Check the clock, as well as the timer on your boiler if you use it since they can easily be forgotten when the clocks change. It’s important that the clock and timer are set to the correct time – this can have an impact on when your hot water comes out and when your heating comes on.

Check your diverter valve

A diverter valve enables your boiler to switch between hot water and heating. You should check your diverter valve if you still have no hot water but your central heating is fine. It may be that you need to replace it or it may be stuck in the central heating position.

Check your boiler pressure 

If you have a combi boiler, you may be experiencing a low boiler pressure if you still have no hot water. The pressure for boilers should be between 1-1.5 bar, but manufacturers recommend a pressure of 1.3 bar. A manometer will usually display the pressure your boiler is on, and is located on the water supply pipe connected to the boiler.

Check if your pipes are frozen

Another reason for no hot water may be due to frozen pipes, which can occur during winter. The condensate pipe is the pipe most likely to freeze since it is located outside of your house – it is usually a diagonal pipe leading to a drain. To fix this problem, pour hot water on the pipe, not boiling water. If you still don’t have hot water, try the same method again. However, if you’re still facing this problem after trying to unfreeze your pipes, get in touch with our plumbing and heating services from our list here.

This is what you can do to check if you have no hot water, which hopefully helps to resolve your problem. For any enquiries, our plumbers from our list here will be able to help.
