The diagram below shows how a central heating system in a house works.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
You should write at least 150 words.
The diagram above explains how the central heat system work in domestic houses.
First and foremost, cold water enters the house from the roof then the water distributes to the whole house, before that it goes through storage tank in order to be reserved when the renter needs it, some amounts of the water return back. when it comes above the demands. a little amount of water pumps to hot water taps.
in the same time there is a device which controls and monitors the amount of water if it is much.
Any way, after passing the storage tank the water enters the boiler which is generated by either gas or oil, then the flowing of water is divided into different tubes, one tube is for carrying hot water around the home, other for spreading out the cold water.
To sum up, the operation of distributing the water around the house is a little complicated and involves several stages to be shared sufficiently.

Before anyone assesses the content of your work, can I ask why you decided to write an essay on this particular subject, please?
Did you know anything about plumbing and central heating systems in general before you looked at this question or have you just tried to follow the diagram in writing your essay?
Actually, I know a little about central heating, but I think the topic is diffecult to me to clarify my openion.
But really I have to write about any topic even if I do not have experience with it [color=darkblue](my IELTS exam is on 1552010)
First and foremost, cold water enters the house from the MAINS SUPPLY. IT THEN SERVICES EVERY APPLIANCE IN THE HOUSE THAT REQUIRES COLD WATER TO FUNCTION. It THEN goes TO A storage tank in order to be reserved FOR when the USER needs it. Some amounts of the water return back when it BEcomes IN EXCESS TO demands. AN amount of water SERVES THE hot water taps.
AT the same time there is a device which controls and monitors the amount of water if it is TOO much.
Any way, after passing the FLOW of water is divided into different tubes, one tube is for carrying hot water around the home, THE other TUBE IF FOR RETURNING THE NOW COOLER WATER TO THE BOILER.
To sum up, the operation of distributing the water around the house is a little complicated and involves several stages to be shared SIMULTANEOUSLY.
I’m afraid this is all wrong. I cannot describe the drawing, for it itself is wrong.
WE have hot water drawn from the boiler and sent to the radiators. An individual radiator can be isolated from this supply if not required. After passing through the radiators, the now “cooler” water is returned to the boiler to be reheated. This water is also used to heat domestic hot water in the storage tank, by indirect heat exchange.
The "overflow pipe shown in the drawing is NOT an overflow pipe. It is a VENT pipe to protect the storage tank from overheating. This tank can also be heated from another source; by an immersion heater in the summer months when the heating is not required.
The whole exercise should be scrapped. It is all wrong.
Thank you Kitosdad. I was very worried about the diagram and the result it had on the content.
Although I was never a heating engineer I was a proficient DIYer, and the water system of my home was my special interest. I have owned around twenty houses over the years, and I did EVERYTHING in those houses with the help of my wife. You name it, we have done it, and more than once!
Well, I don’t have your expertise, but the first alarm bells started ringing for me when it appeared that the cold water tank wasn’t being fed by the supply into the house at all, whilst water was being fed two ways into the boiler, or was being pumped in one side, out the other, and around in a continuous loop!
