Direct (?) Hot water cylinder needed.

Hi all,

Looking for some advice please regarding a new hot water cylinder. The current one has been in this house since it was built (1981) and I'm sure it's pretty furred up as the water in this area is very hard and we struggle to get more than one bath's hot water out of it. It is a one bed house, with two people living in it. The shower gets its water from the tank in the loft and heats it independently - but my main aim is to be able to have 2 baths of hot water a day rather than having to share a bath with my other half every night.....although that does have its benefits ;)

We would ideally like to continue to use economy 7, however the size of the tank that's in there currently are no longer made. The dimensions of the tank at the moment including insulation are 400x1050. It appears that I would be able to buy a replacement of the same dimensions, however the dimensions of the new ones do not include the insulation. This is where I hit a problem; due to the spacial confines of the airing cupboard, it would not be possible to fit a tank of that size in there. Is it possible to buy a replacement tank and use thinner insulation?

From my limited understanding of these things, I assume that a tank that utilises economy 7 has two elements? One to heat during the day if required and the main one that is used at night? Would it be possible to buy single element cylinder and fit a timer on it so it's only heating the water at night?

Obviously I'm on a tight budget, and have been quoted about £500 fitted, for a smaller cylinder which is too much. I have the assistance of family when it comes to the actual installation and any associated adjustments to pipework, so am looking for advice please on what a sensible way forward would be for only the procurement of a new cylinder.

Any helpful responses gratefully appreciated.

    we had a similar problem in our last house. airing cupboard in the bedroom. so i made an extra door frame and brought the door forward.
    re the twin element tanks. i dont think thats the way E7 works?
    (i maybe wrong though).



    re direct tanks.
    just buy an indirect one and dont use the primary circuit coil.
    Get some gorm.
