Reasons to Drain Central Heating System

Many homeowners find out that they need the drain in an emergency when they see a leakage in their home. This happens when sludge builds up in your system, and water comes out. Therefore, it is necessary to drain it on time to prevent damage.

The exciting thing is that many people drain their heating system after a few years. This way, they keep the whole system running smoothly, preventing any emergency leakage or problem.  

How to Drain Central Heating System?

Undoubtedly, the heating system provides you with a comfortable environment. Therefore, you should treat it with great care. The following steps will guide you on how to drain it. 

Turn Off Your System

The first thing that matters most is safety; thus, before starting the process, make sure you complete the boiler switch. After this, wait for the pipes to cool down completely.

Shut Down the Water Intake Valve

By shutting down the water entrance, you will be sure that no water is entering the system while working hard to drain. If you have a combi boiler, the hot water can come directly to this. Therefore, you need to close the main water valve, which can be under the kitchen sink. But, if you have a hot water cylinder, you will have a pipe that goes from cold water storage to a hot water cylinder, with the valve on it. 

Attach the Hosepipe

The next step is to attach the hosepipe to the correct radiator valve. YOu can look for this on the right or the left side at the bottom. This valve is coming off at a 45-degree angle. Once you have located the radiator with the drain-off valve, grab your hose and clip it around the valve. The end of the hosepipe should be in some bucket or running outside to prevent mess. 

Start Daring Your Radiators.

Now, it is time to check all the radiators to ensure their valve is open. If it is, then all the water will start draining out.

Open Bleed Valves and Speed up the Process

You can quickly speed up the entire process by bleeding the radiators. You will hear the air being sucked into the system, so leave it to drain for a maximum of 15 minutes. Go to the downstairs radiators and open the bleed valve; if the water is coming out, tighten it up again and wait. When you hear the air going down to the system, open the bleed valve and the downstairs radiators’ identical valves. This will ensure that you take out every last drop of water from the system.

Close All the Valves

Once fully drained, close all the valves again, and remove the hosepipe. It would be best to keep the bucket and mop with you to clean.

Refill your Central Heating System

The process of refilling starts right after you close all the valves that you open during the process. 

Thus, these steps will help you drain the system yourself, but you should be very careful during the process. 

A Quick Round Off!
