Trying to get my head around a central heating system, and need some help please.
My parents have moved into a temporary let, which has a system boiler. There is an oil fired boiler in the kitchen, hot water tank and header tank in the bedroom cupboard above and oil tank outside.
The query I have is that there is no oil in the tank outside, which is actually full of water as one of the caps has been left off it, so what is providing the hot water?
There is an immersion switch (which works) but hasn't been used other than to check if it works. The heating hasn't been on apart from firing it up using the heat advance button. However, there is plenty of hot water.
Forgive my ignorance, but where does the hot water supply in this type of set up come from? I understand that the hot water passes through the boiler but I can't understand where the heating of it takes place?
Obviously oil will be needed for the heating - will it be necessary to have the system flushed? Obviously, after the cap is replaced. Would the company who fill up the tank do this or would a heating engineer be needed?
Thanks in advance
