Steps Involved In Draining A Central Heating System
Shut Down Your System
Before starting to drain, turn off the system. Once the pipes are completely cooled, you can begin replacing or restoring the radiators.
Extinguish Any Solid Fuel Fires
If the boiler burns solid fuels, you should ensure that you extinguish the fire and wait until the boiler is completely cool before turning it back on.
Turn Off Your Boiler’s Water Supply.
Make confident you block above the water amount before draining the system, so no water will enter the unit while you’re working on it. The water flow has to be stopped by tying the ball valve to wood laid on top of the cistern. If there isn’t a separate stop tap, turn the ball valve to stop the water.
Select The Suitable Drain Valve And Radiator
If your house has a first floor, then your correct radiator is located somewhere on that floor. The drain valve is usually found at the bottom of the radiator. Connect a garden hose to the outlet with a clip, so the water runs outside. Clips prevent hose pipes from slipping, so the water doesn’t get all over the place. Additionally, you can practice a flat-head screwdriver to tighten the clip.
Begin Bleeding Your Radiator
The real work begins now. First, it would help open the bleed valve, allowing water to flow freely through the system. Second, it would help to start with the radiators at the top of the building to make the water flow faster. You should wait about 15 minutes before opening the radiator bleed valves downstairs.
Activate The Drain Valve And Empty The Water
Verify that all valves on your radiators are open and check twice if necessary. After that, open the radiator valve that is attached to the hosepipe and drain the heating system. Depending on the variety of methods you have, the process may take up to an hour. To speed up the process, open all your radiator bleed valves.
Refill The Heating System
Once you’ve finished working, you’ll have to refill the system. All of the valves you opened earlier, as well as the radiator’s drain cock, should be closed now. Unite the string in the feed tank and allow the water to fill the system. If you want to prevent corrosion and limescale buildup in your system:-
Add an inhibitor.
Tighten all valves and activate the power supply.
Heat the system again before blotting the radiators.
Make certain there are no crevices in each joint or valve.
You can see that draining a central heating system is easy, and anyone can do it provided they have the right tools and some skills.
