How to bleed radiators with a combi boiler
Does your home feel cold and your radiators are not giving off as much heat as they should? It’s possible that your radiators are filled with air and need to be bled. Bleeding your radiators is a simple process that can be done with a combi boiler, ensuring that your radiators are functioning properly and heating your home efficiently.
Why do radiators need to be bled?
In a central heating system, air can enter the radiators, causing pockets of trapped air. When this happens, the radiators may not heat up properly or may only heat up at the bottom. Bleeding the radiators releases the trapped air, allowing hot water to flow freely through the entire radiator and heat up your home evenly.
What do you need to bleed your radiators?
To bleed your radiators, you’ll need a radiator key or a flat-headed screwdriver, a cloth or towel to catch any water, and possibly a small container in case there is a lot of water to drain. Make sure the heating system is turned off and cool before starting the bleeding process.
How to bleed your radiators:
1. Start by identifying which radiators in your home need bleeding. Look for radiators that are cold at the top or have unequal heat distribution.
2. Once you’ve identified the radiator, locate the bleed valve. The bleed valve is usually located at the top of the radiator or on the side. It will have a small square valve or a slot that can be turned with a screwdriver.
3. Place the cloth or towel under the bleed valve to catch any water that may come out.
4. Insert the radiator key or a flat-headed screwdriver into the bleed valve and slowly turn it anti-clockwise. You will hear a hissing sound as the trapped air escapes. Keep turning until water starts to come out.
5. Once water starts to come out, quickly and carefully close the bleed valve by turning it clockwise.
6. Repeat the process for all the radiators that need bleeding. Remember to close the bleed valve securely after bleeding each radiator.
Bleeding your radiators with a combi boiler is a straightforward process that can help to improve the efficiency and effectiveness of your heating system. By removing trapped air, you’ll ensure that your radiators are working at their best, providing a warm and comfortable environment in your home.
What is a Combi Boiler?
A combi boiler, also known as a combination boiler, is a highly efficient water heater and central heating system in one unit. It is a popular choice for homes because it provides both hot water and heating on demand, without the need for a separate cylinder or storage tank.
Combi boilers work by heating water directly from the mains supply and then distributing it whenever hot water or heating is needed. The main advantage of a combi boiler is that it eliminates the need for a separate water tank, saving space and reducing installation costs.
Compared to traditional system boilers, combi boilers are more compact and can be installed in smaller properties, such as apartments and townhouses. They are also energy efficient, as they only heat the water that is required, resulting in lower energy bills.
A combi boiler offers instant hot water, as there is no need to wait for a cylinder to heat up. It can provide unlimited hot water, as long as the mains water supply is maintained. Additionally, combi boilers are equipped with various safety features, such as pressure relief valves, to ensure safe and reliable operation.
The versatile nature of a combi boiler makes it suitable for various heating systems, including radiators, underfloor heating, and even towel rails. It is important to follow the manufacturer’s instructions and guidelines for installation, operation, and maintenance to ensure optimum performance and prolong the lifespan of the combi boiler.

Why Bleeding Radiators is Important
Bleeding radiators plays a critical role in maintaining the efficiency and effectiveness of your central heating system. Over time, air can become trapped inside your radiators, causing them to develop pockets of cold air. This prevents the hot water from circulating properly and can lead to cold spots in your rooms.
By bleeding your radiators, you release the trapped air, allowing the hot water to flow freely and evenly throughout the system. This will ensure that your radiators heat your rooms efficiently and effectively, keeping your home warm and cozy.
Regularly bleeding your radiators can also help extend the lifespan of your central heating system and prevent costly repairs. When air gets trapped inside a radiator, it can cause corrosion and reduce the efficiency of the system. By bleeding the radiators, you prevent this corrosion and maintain the overall health of your heating system.
Bleeding radiators is a relatively simple process that can be easily done by homeowners. All you need is a radiator key or a flathead screwdriver, depending on the type of radiator valve you have. It’s recommended to bleed your radiators at least once a year, especially before the colder months when you rely on your heating system the most.
Overall, bleeding radiators is an essential maintenance task that ensures your heating system operates efficiently, effectively, and lasts longer. By taking a few minutes to bleed your radiators regularly, you can optimize the performance of your central heating system and enjoy a comfortable and warm home throughout the year.
