Replacement hot water cylinder

spirit

Hi,

I'm reading up on things I will need for the new house. I did a second viewing on it today to look at more detail.

It has an airing cupboard with I suspect quite an old hot water storage tank. I say old, but probably the original since the house is about 30 years old. It has a padded hot water jacket on it and I believe that factory lagged ones have been around for years?

I did a quick Google search just now but got a bit overwhelmed with the different sorts.

It hasn't got a combi boiler.

Can anyone advise what I should be looking for please?

Hi
The type of hot water cylinder you will need depends on the type of heating in the house or the type of heating you are going to install.
For instance I changed from a solid fuel system which used a cylinder to a gas combi boiler which did not need one.
Some more information will help

Hi, sorry, it's a gas boiler and not a combi one

Count the pipes going in...

Measure the height..


& tell us where abouts the pipes go into the cylinder.


ooooooooo & how many immersion heaters are on it & where they are...

I would wait and see if you need to replace the boiler.
If so get a combi boiler and do away with the storage.
Just because its old doesn't mean it is no good, the cylinder is only as efficient as the insulation.

OK, can't do that just yet though as I've not bought the house yet. Will update once I've moved in. Just did a swift-ish second viewing today and noticed the old fashioned jacket.

Anywhere from £100 to £350 for a normal vented system cylinder + fittings & labour.

But why do you need to change it? As Orkatec says, it may be perfectly good and wont need updating. You can upgrade the insulation with extra hot water cylinder jackets. Can't help thinking you are being a bit hasty.

The reason for my thinking is that if it is the original, 30 years of hard water scale and it's not going to be much kop.

I'm taking my water softener with me which i know will eradicate the scale but I guess will take a long time on that much scale.

Tanks with lagging applied during manufacture have a lower heat loss than those with a loose jacket.

Agreed but the to recover the cost of a new cylinder plus installation based only on the energy savings between a factory lagged one and one lagged in situ will take years.
