That is a normal system, basically only two types in this country, the one you have just seen and combi boiler which heats the water up on demand unlike the one you have just seen which stores hot water in the cylinder

I more meant about the loft tanks than a hot water tank, or do they go hand in hand?

The realtor thought that it still had a combi boiler. Would that be feeding the hot water tank, maybe with the element maintaining temp, or is it just electric hot water?

Oi!!! Speak English.

Sounds similar to mine - which is a primatic system.  I've got a back boiler and one cold tank in the loft though, not two.  It feeds both the central heating and the hot water from the one hot water tank.  As I understand there's a kind of tank inside the tank affair with the cylinder.
It confused me completely after I turned off all the water to the house, drained the hot water from the taps and then had gallons and gallons come out of the radiators - wayyyy more that could possibly be held in the individual radiator.
I get the feeling it's a bit old fashioned and probably costs a bit more to run than the combi-boiler setup.  I'll be taking the plunge in the next year to change over I think.

Main reason for putting the cold water tank feeding the hot water cylinder (doesnt matter where that is) up in loft, is to get hot water pressure......higher up the tank the higher the hot water pressure.

In a bungalow i completely gutted and started again with.....i wasnt happy with the hot water pressure......so had fitted a 1 bar on demand pump fitted........which meant as soon as a hot tap was turn on the pump fired up and pumped the hot water......

I also had a 3 bar power shower installed.....you should have seen the cold water tank it need to supply it   It was called a 'coffin' tank.....as it was literally as big as a coffin.......you got 5 mins to have a shower before it drained all the hot water  

But the shower was great   Like standing under the Niagra Falls (tho with hot water)
