Central Heating means heating from a central source. In Central Heating Systems water is the medium. The water gets hot so that all the areas needing it get it.
if you're planning on getting a boiler/system fitted or replaced there are specific things that you should bear in mind. One of the first things you should do is see what type of system you already have installed to make sure you've got the needs required for your new system. Also you need to think about what you need from your central heating system, not forgetting things like ; are you wanting instant or stored hot water? Different parts of your house heated independently, if so how many? And do you need your boiler hidden away?
There is no standard Central Heating System, each system is customized to suit individual wants. Even if you only have a basic system you must still have the power to programme it correctly so that it can look after itself. You should be ready to set it on a timer so that it can mechanically turn itself off and on. With a complicated system you can take this one step further and have the control to set your Central Heating System so that it keeps your place at just the right temperature and gives you all of the hot water that you will need. You should be able to control all this, with your boiler burning the bare minimum quantity of fuel.
Out of all of the Central Heating Systems, the totally pumped systems remain the most common and well-liked. In a fully pumped Central Heating System the water is heated by a boiler and sent round the pipework by a pump ; this water is then routed to the radiator circuit and to the hot water cylinder by a motorised valve. As well as this the user has a lot of control over how heat is distributed and what time and temperature it is supplied.
a very important thing to be conscious of with a totally pumped Central Heating System is the way to drain it. Draining your system is something you will probably have to or wish to do in the lifetime of your Central Heating System.
the real reason for the general public for draining their Central Heating System is to wash the radiators. Before you do anything to the actual radiator you must turn off the boiler and any gas or electrical that supplies the boiler. It's also vital that you don't let any more water into the system while you drain it. electrical heating systems
are an addition to your regular system which can be controlled in several ways like by using gas heating system
Your Central Heating tank where the water is fed into has a ball valve that's the same as the one seen in your toilet tank. This ball valve is a ball attached to an arm that, when lifted closes the valve, which means when the tank is full no more water can get in as the valve is closed. However when some water is drawn off the tank, the ball drops, the valve opens and more water gets into the tank, this is what must be stopped when draining your radiator. One of the best paths to stop this is by placing a piece of wood across the tank and tying the price arm to it, which will close this valve.
When all of these precautions have been carried out, you need to fasten a hosepipe to the part of your radiator called the outlet and run the end of the hosepipe outside. The water from your radiator will flow through the hosepipe and out of your radiator system. You must confirm before you start cleaning or replacing your radiator that all of the water has belligerently been drained out.
To make your system drain quicker you need to open any bleed valves on your radiators, beginning with the radiators on the top floor and working your way down. When the water is drained off you are free to work on your radiator.
