Moving a hot water tank

iandv

Hi

I am getting a new regular central heating system installed tomorrow which will replace the exisiting 1960 system.

The question I have is can you put the hot water tank in a different location as it will be a new install (new tanks in the loft, radiators etc)

At the moment the hot water tank is in an airing cupboard in the bathroom, but ideally I would like to move it from here to free up the extra space in the bathroom, is this possible?

For example could the hot water tank go in the loft? or is that too dangerous? Couldnt get a combi because of water pressure etc

TIA

Unless you add significant extra cost there is no way of getting a hot water cylinder in a loft using a conventional system.

Also the job would be priced as is & any alterations will be charged.

Hi,

H/W cylinder can go anywhere in the house.
If in the loft stand it over or near a supporting wall to take the weight.
You then have to fit the cold storage above it. Do you have the height to do that?

Edit, c/h expansion tank must also be above the cyl. Unless they are fitting a system boiler.

no its not a system boiler its a conventional system, so can it be done with a conventional system or can it only be done with a system boiler? There seems to be enough head room in the loft.

Didnt know about system boilers, but its too late now as they are coming tomorrow, have not paid anything yet though.

All I want is to move the hot water tank out of the bathroom, ideally into the loft, so just wanted to know what to ask the installers tommorrow?

Thanks

Hi

If this is the first time you are mentioning this to the installer be prepared for a bit of teeth sucking.

They are all geared up for the work quoted and you are now moving the goalposts on day one of install.

I would be a bit put out.

Well if they can do it, and only they can advise if it is both practicable and workable, I would expect that it will cost you a fair bit for labour, materials and joiners fees etc.

Eh? CH expansion says it is a system boiler - and if you have one, it must at least be above the coil on the HW tank, but best above the HW tank as a whole.

you need a fair height in the loft to fit the HW cylinder and the CWS tank/s..
most modern houses dont have the height.

The best way to free up the space taken by the airing cupboard would be to rip out your existing cold water and CH heating tank system in the loft and install a hot water 'unvented' cylinder. This does away with the need for cold water storage tanks and could be put in the loft in place of the tanks and would provide mains pressure hot and cold water, as well as power showers without the need for seperate pumps.

However, you do need decent mains pressure and flow for this to work, which seems doubtful as you say you can't have a combi due to pressure. It may be possible to overcome your low pressure by having a larger bore (22mm instead of 15mm) pipe installed from your water main/meter all the way into the house and up to the loft. This would not be cheap though. Also, have you spoken to or complained to your local water authority about the low pressure? They may be able to do something about this themselves.

At this late stage you may be better off letting you new heating installers go ahead as planned, and look at your options again another time. Hope this helps.

How is the expense involved in that going to help his pressure problem?

In a C/H system with a feed and expansion cistern said f&e must be above the coil, as you say, but would share the same platform as the main cold storage in practice.

A system boiler has an expansion vessel built into it and therefore needs no such cistern.It is a sealed system. It is filled with mains cold water. I would hope the OP has a minimum of 1 bar pressure to do this.
