Those who have a central heating system might not always be well aware of the many signs that could indicate a problem with the system. These can include the radiators not heating, funny noises, or a lack of hot water. If you have any of these symptoms or are concerned that your central heating system might have air trapped in it, contact a professional heating engineer. While removing air from a heating system may seem like a difficult task, it’s not.
Air trapped in the system can cause bubbling sounds to come from the radiators, for example. If this happens in the winter it is less than ideal because your radiators will experience cold spots which means they are not running as efficiently as they should be. This means you are wasting money on insufficient heating for your home.
Why does it happen? Well, one of the causes can be installing the pump above the supply tank. A build up of sludge inside the pipes or an accumulation of hydrogen from rust can also lead to air becoming trapped in the system. Leaks can also lead to build up of trapped air in a system and this can be the result of frequent re-pressurising of the boiler.
One of the first signs of air trapped in your heating system is the presence of cold spots in a radiator. If you’ve ever had this problem, then you’ll know that a radiator might feel cold at the top but warmer at the bottom. If you’re unable to determine what’s causing the air, you can try bleeding the radiators. If this doesn’t work, you can try adjusting the thermostat higher. This might allow the trapped gas to escape from the system.
If the problem persists, you should consider the cause. If the problem is caused by a faulty check valve, you should consider replacing the check valve immediately. If you notice that your boiler is making loud clanging noises or whistling like a kettle, there could be a problem with the fan. To find out for sure, consider contacting Boiler repair Cheltenham at a site like The Combi Man, a provider of Boiler repair Cheltenham services.
There are several other signs that air might be trapped in your heating system. The most obvious sign is a leaking radiator. If you notice these symptoms, you should have your radiators checked immediately. If there’s no water in the tank, the water may not be able to circulate properly. A faulty check valve can allow contaminants to enter your water supply, which can lead to the problem with your heating system.
Bleeding your radiators will help to relieve the system of trapped air. You will need a radiator bleed key or screwdriver, a towel for protecting the flooring and a small pot for catching any liquid that comes out.
