How to refill a radiator central heating system.
Your central heating system keeps your house warm, but it requires regular maintenance and care. One important part of keeping your central heating system in good shape is knowing when and how to refill your radiators.
This article will walk you through how to refill your radiators step by step. We’ll cover what tools you need, how to identify if your radiator needs refilling, and how to do it safely.
So, let’s get started.
How To Refill Radiator Central Heating
Radiators, particularly those in older buildings, can lose a lot of heat through the top. To stop this, you can buy a radiator reflector – a panel that reflects the heat back into the room – for around £5.
Alternatively, you can fit foil panels behind the radiators. These panels reflect the heat back into the room, and can be picked up cheaply from DIY stores.
Insulate your pipes
If your pipes are exposed, they will lose heat. To prevent this, you can wrap them in insulation. This can be bought from DIY stores, and is relatively cheap.
You could also try lagging your hot water tank, as this will stop it losing heat.
Fit thermostatic radiator valves (TRVs)
Thermostatic radiator valves (TRVs) are fitted to individual radiators. They allow you to set the temperature for each radiator, so you can save energy by only heating the rooms that are in use.
You can pick up TRVs for around £10 from DIY stores.
Use a room thermostat
A room thermostat allows you to set the temperature for the whole of your home. This means that you can save energy by only heating your home to the temperature you need.
You can pick up a room thermostat for around £20 from DIY stores.
Fit radiator covers
Radiator covers are panels that fit over the radiator. They can help to stop the radiator losing heat, and can also improve the look of your room.
You can pick up radiator covers for around £20 from DIY stores.
Bleed your radiators
If your radiators are not heating up properly, you may need to bleed them. This involves releasing any trapped air from the radiator, which can improve its efficiency.

How Do You Check The Level Of Coolant In A Radiator Central Heating System?
To check if the coolant level in your radiator central heating system is low, follow these steps:
1. Locate the radiator: Find the location of the radiator in your home. It is usually located in a central location, such as the living room or bedroom, and is usually connected to the heating system by pipes.
2. Check the coolant level: Look for a coolant level indicator on the radiator. It typically looks like a yellow or green plastic tube or stick with a small hole at the top. The coolant level should be in the “full” range. If it’s not, you need to add more coolant.
3. Open the radiator cap: Remove the radiator cap by twisting it counter-clockwise. Be careful, as coolant may spill out.
4. Check the coolant level: Look for a coolant level indicator on the side of the radiator. It typically looks like a yellow or green plastic tube or stick with a small hole at the top. The coolant level should be in the “full” range. If it’s not, you need to add more coolant.
5. Add coolant: If the coolant level is low, add the correct type of coolant to the radiator. Use only distilled water or coolant specifically designed for your radiator heating system. Do not add any other type of liquid, such as antifreeze, as this can damage your system.
6. Replace the radiator cap: Replace the radiator cap by twisting it clockwise. Make sure it is securely tightened.
7. Check the coolant level again: Check the coolant level again to ensure that it is in the “full” range.
If the coolant level is low, add more coolant and recheck the level. If the level is still low, there may be a more serious issue with the system. In this case, it’s best to contact a professional heating technician for assistance.
Why Is It Important To Regularly Check And Refill The Coolant In A Radiator Central Heating System?
The coolant in a radiator central heating system plays a crucial role in maintaining the efficiency and safety of the system. It helps to regulate the temperature of the system, preventing overheating and reducing the risk of damage to the components.
The coolant also acts as a lubricant, helping to prevent the moving parts from wearing out prematurely. Additionally, the coolant helps to prevent the formation of rust and scale, which can clog the system and reduce its efficiency.
It is important to regularly check the coolant level in the radiator central heating system to ensure that it is sufficient. If the coolant level is too low, the system will not be able to effectively regulate temperature, which can lead to overheating and damage to the components.
It is also important to regularly refill the coolant in the system. Over time, the coolant will evaporate, and the system will need to be topped off to maintain the proper level. Neglecting to top off the coolant can lead to overheating and damage to the system.
Checking and refilling the coolant in a radiator central heating system is a simple task that can be performed quickly and easily. By taking the time to regularly perform this maintenance, you can help to ensure that your system operates at peak efficiency and lasts for many years.
How Do You Safely Refill The Coolant In A Radiator Central Heating System?
1. Turn off the heating system: This is an important step to prevent burns from hot water or steam.
2. Allow the radiator to cool down: Wait for the system to cool to room temperature before proceeding.
3. Drain the radiator: Place a container under the radiator valve and open the bleed valve. This will allow the coolant to drain out.
4. Close the bleed valve: Once the coolant has drained out, close the bleed valve.
5. Refill the radiator: Open the radiator valve and pour in the correct type of coolant. Be sure to use the correct type of coolant for your system, as using the wrong type can cause problems.
6. Check the level: Check the level of the coolant in the radiator using a dipstick or level gauge. The coolant should be between the “low” and “full” marks on the radiator.
7. Repeat steps 3-6: Repeat steps 3-6 for each radiator in the system.
8. Restart the heating system: Turn the heating system back on and allow the new coolant to circulate.
It’s important to use the correct type of coolant for your system, as using the wrong type can cause problems. It’s also a good idea to regularly check the coolant level in your radiator system, as low levels can cause the system to overheat.
What Safety Precautions Should Be Taken When Refilling The Coolant In A Radiator Central Heating System?
When refilling the coolant in a radiator central heating system, it is important to take safety precautions to prevent injury and avoid damage to the system. Here are some precautions that should be taken when refilling the coolant:
1. Turn off the power to the central heating system: This will prevent any accidental activation of the system while you are working on it.
2. Drain the radiator: Before refilling the coolant, it is important to drain the radiator completely to remove any old coolant and debris. You can do this by loosening the drain valve at the bottom of the radiator and allowing the water to flow out into a drain pan.
3. Wait for the system to cool down: Before refilling the coolant, it is important to wait for the system to cool down completely. This will ensure that the coolant you add is at the correct temperature and will not damage the system.
4. Use the correct type of coolant: It is important to use the correct type of coolant for your central heating system. Using the wrong type of coolant can cause damage to the system, so it is important to check the manufacturer’s instructions carefully.
5. Avoid overfilling the system: Overfilling the cooling system can cause the coolant to overflow and damage the system. It is important to carefully measure the amount of coolant you need to add to avoid overfilling the system.
6. Bleed the radiator: After refilling the coolant, it is important to bleed the radiator to remove any air that may have been trapped in the system. You can do this by slowly turning the radiator’s bleed valve counterclockwise until a steady stream of coolant flows out.
7. Test the system: After refilling the coolant, it is important to test the system to ensure that it is working properly. You can do this by checking the system’s pressure gauge and thermostat, and by listening for any unusual noises.
By taking these precautions, you can safely refill the coolant in your radiator central heating system and avoid any potential damage to the system or yourself.
