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?

It may be a thermal store for CH only. Check to see if the CH pipes run off
it. It may have been a DHW and CH thermal store but maybe the coil was
caked up and someone unwisely thought a combi would solve the problem rather
than descaling. Is there a cold water tank in the loft? Do a bit more
searching and let us know.

Could it just be a remnant of an old conventional heating system? Is
the tank actually full of water?

Does the boiler fire up for *all* hot water taps?

A perfectly acceptable use of a combi boiler is to use the HW side for (say)
just the kitchen tap, and use the CH side to heat both the radiators and a
tank of stored hot water - using a Y-Plan or S-Plan arrangement as for a
conventional boiler. The stored hot water is then used for things which need
a high delivery rate - like running a bath.

Maybe this is what your father has got?

This is how it works in our, house. In the airing cupboard there is
an insulated hot water tank which connects to ho****er taps around
the house, when you run a tap, hot water comes from the tank. The
boiler fires up to refill the tank. If the boiler does fail there is
also an immersion heater.
