I wonder if anyone can give me an insight into something.
My father has just bought a house, and he's thinking of converting a large walk-in airing cupboard upstairs into an en-suite. But there's something strange about the heating system.
In the cupboard is a standard HW tank, with an electronic timer for HW and CH. There's also a lot of pipework going off to the various radiators around the house. All well and good. But downstairs in the kitchen is a combi boiler.
Whenever you turn on the CH or run a HW tap, the combi fires up and provides hot water to the tap/radiators.
So whats the point of having a HW tank upstairs? As far as i can tell it doesnt actually acheive anything.
Or am i missing something?
