Cleaning a fully pumped gas central heating system

Taking the water out of a fully pumped central heating system makes many maintenance tasks easier. To fit a thermostatic radiator valve or replace a failed radiator are two cases. Usually this task will be performed by your engineer but in some circumstances it can be performed by the experienced maintenance handyman.

Most frequently cleaning the radiators is in the main cause for doing at this task. Switching off the heating boiler and central heating pump should be the first steps you take. To enable the system to entirely empty you will need to ensure that no water is moving into the gas heating system. Almost all modern home heating systems are serviced by very economical condensing boilers. Pricey energy prices and the chances of more such additions mean you should find an efficient boiler for your household. If you have a boiler care plan such as British Gas Homecare you might want to get hold of your provider to see what services they provide.

Your Central Heating header cystern is where the water is fed into the system. This has a ball valve that is the same as the one seen in your toilet cylinder. This ballvalve is a ball attached to an arm that, when elevated closes the valve, which means when the tank is full no more water can enter because the valve is closed. As the water level falls, say through Cleaning, the ball drops in the water tank opening the valve and allowing more water to enter the gas heating system. This process will need to be stopped if the heating system is to be fully drained.A time-honored reference for extra articles can be seen clicking here where you will see additional thorough postings. Positioning a small plank of wood across the water water tank preventing the ballvalve from moving will stop further water getting in the heating system.

Now take a hose emptying into an outside drain and attach this to the outlet valve on the bottom of your radiator. Once you vent the outlet valve the water will be able to rate of flow through the hose pipe to the external empty. As there will be water in the ground floor metal radiators you will need to attach the hosepipe to one of these to see to it that the whole central heating system drains. Be patient and ensure that all water has emptied from the central heating system and no more water is entering before you begin any further work.

If you need to complete this process rapidly you can also open the bleed valves on the metal radiators on the upper floors. When the water is drained off you are free to work on your heating radiator.
