A boiler must supply your home with central heating and domestic hot water. If you’ve discovered that hot water is flowing from your taps, but you’re not getting central heating, you’ve got something wrong.
Thermostats let you control the central heating system’s temperature, and the time it is expected to be on. Check the setting if you’re heating isn’t coming on when you expect it to. Boiler Pressure is the term to refer to the pressure of hot water that flows across the central heating unit. If the boiler’s pressure falls too low, the central heating system will not perform its job.
Intensifying the pressure of your boiler is something you can do without calling in an engineer in heating. If you’re even in doubt you’re not sure, don’t hesitate to call an expert. Problems with thermostats and low pressure in the boiler aren’t all the reasons you may have hot domestic water but no heating. However, this is where things get more complicated.
If your thermostat is working and the pressure in your boiler is sufficient, it may be a problem that requires a professional’s repair. Common causes for hot water but no heating could be broken diaphragms or locks, as well as an issue with the motorized valves. In the case of heating systems with the combination boiler, there might be a problem regarding your diverter valve. Combi boilers offer hot and heating at the touch of a button. The diverter valve is designed to direct the hot water to either radiators or hot outlets for the water. If the valve becomes stuck, you might have hot water but no heating or vice versa.
A Gas Safe certified engineer can detect airlocks and diaphragms that have failed and motorized valves and diverter valves and make the required repairs or replace broken components.
You ought to be able to depend upon your heating system to supply your house with heat and hot water. If it’s not capable of doing the two, you’ll need to have it repaired as soon as possible. No one issue could cause your boiler to be unable to provide hot water or heat.
If your boiler has stopped getting power, we can start exploring possible causes. Your boiler will display an error message to help identify the issue’s root. But, to give you some suggestions on some possible issues to consider:
If the boiler leaks the tank or pipes, this is an obvious sign of corrosion. It could also be due to bad repair. In either case, we suggest seeking out an engineer who will be able to determine the cause and fix the leak.
We’ve previously covered kettle-like noises due to an accumulation of sludge on your heat exchanger.
The banging can be due to the pipe work or an inner component breaking loose, but it could also be due to particles accumulating around the heat exchanger. The banging sound could signify that the pump responsible for pumping boiling hot water out of the boiler to the central heating system is in danger of failing.
A sound that isn’t too far from banging could be an ear-splitting sound resulting from leaky pipe work. It could also mean that the fan in the boiler is blocked.
A buzzing sound could mean that the electrical components in the boiler are not functioning correctly and will likely require replacement. If the noise originates from the thermostat, it could indicate that the electrical conductor has become dirty and must be replaced.
Boilers usually have an operational sound that is similar to the sound of a slight humming. To find the quietest models, look to find Quiet Mark accredited boilers – but the loud humming may indicate a broken part (most likely, the central heating unit).
Too much air inside pipes could lead to obstructions that stop the water from flowing through your heating unit. If you are hearing this from a radiator, then it’s most likely that the pipes need to be cleaned.
Suppose you find that the thermostat is functioning precisely as it should, and the boiler’s pressure is consistent with the manufacturer’s instructions. In that case, it’s time to contact a Gas Safe registered engineer.
The cost of repairing a boiler will differ dependent on the issue and the rates paid by the engineer. They can vary significantly based on the issue and the costs paid by the installer. You could reduce costs by solving specific boiler issues on your own. However, it is essential to note that most boiler issues require the skills of a Gas Safe registered engineer. A Gas Safe registered engineer best deals with specific boiler issues.
Sometimes it’s not economically sensible to fix the boiler. In contrast, a replacement for the boiler will be much more affordable.
As boilers get older, they are less reliable and require repairs more often. Repair costs for boilers increase, and eventually, you reach a point where replacing your boiler is the ideal choice.
Depending on the kind of boiler to be put in place, the new boiler installation prices can range from including installation. When you consider that replacement parts could be priced at several hundred dollars and up, it might be beneficial to make a long-term purchase of a new boiler.

Modern boilers are far more reliable than older boilers and can be protected by a guarantee period. Warranty guarantees ensure that you are covered against the manufacturer in the case of an issue (terms and conditions are permitted) that could help you save money. Additionally, a new boiler can boost efficiency, reducing your heating costs.
Like the vast majority of repair work to boilers, the repair of a boiler must be completed by a Gas Safe registered engineer. Our heating engineer network comprises heating professionals all over the UK, and we regularly examine for their Gas Safe credentials. It’s also easier to connect with the heating engineers within your local area.
