Moving hot press

Yanu

Hi guys,

I bought a bungalow with a small and old hot water cylinder, it needs replacing.
I was thinking of moving it up in the attic, that will give me a bit more storage room downstairs as the house is quite small. At the moment in the attic I have the black plastic cold water tank and a metal small one that I guess is for the heating. Everything is wrapped with insulation making the whole thing very messy.
Can anybody advise on what type of tank I should get? Maybe one that does everything, hot and cold?
I understand that there will be an issue with the gravity and a pump will be needed (os so I have been told..)

Thanks

Your best bet would be have a plumber out to assess what you want and need.

One possibility, would be to fit a combi boiler, this would do your heating give you hot water on demand,and eliminate the need for all the attic tanks and the hotpress.

building regs tgd,s says you must have a storage tank

1.3 The cold water supply to the kitchen sink should
be taken directly from the service pipe supplying
water to the dwelling; the cold water supply to the
bath or shower and the washbasin and to other
appliances in the dwelling should be from a cold
water storage cistern. The bath, shower, washbasin,
and sink should also have a piped supply of hot
water, which may be from a central source or from a
unit water heater.

Wheety

We have a combi boiler which meant we were able to get rid of the hotpress/hot water cylinder but we still have a cold water tank in the attic.

After a consultation with a plumber, I'm keeping the cold water tank and have the hot water one beside it. Everything in the attic. Only thing is that it would probably need to be pressurised so a pump might be necessary

Will definitely need a pump it relies on gravity to feed it.if they are same or similar level gravity won't help

Says 'should' so if you provide an equivalent or better means it satisfies regulations IMO.
Regulations are always behind, and never prevent technical progress.

Yes you can install a combi with a break tank, but kind of defeats the purpose.

OP, glad you got sorted.

wasn't commenting on the combi but on the fact you were advocating removing the attic storage tank which is required to provide water to the cold water in bathrooms and you have to comply with 1.6 The cold water storage cistern should have an
actual capacity of not less than 212 litres in the case
of a dwelling containing up to three bedrooms and an
actual capacity of not less than 340 litres in the case
of a dwelling containing four or more bedrooms.

Hi Daithi, not going to argue to point with you mate.

But the term 'should' indicates best practice, and doesn't rule out an alternative method.
I see many installations without cold water storage and combi boilers, and others with unvented cylinders.

the technical guidance document is not about "best practice"it is the prima fascia method of complying with the building regs which is a legal requirement . it doesn't preclude using an other method which is as good as the tgd,s but the installer using another method must be able to provide document evidence to prove compliance. or else the installation does not comply with building regs

Yanu, are you going to end up with a pressurised hot water tank? This is certainly feasible, but it is important that the tank is easily accessible and that it is regularly serviced. This is also quite an expensive setup. You should also consider whether noise from the pump will be acceptable. It might make sense to locate the pump away from the living area.

This isn't me looking for an argument, just information. You seem to be well up on this stuff. Do you know if in the case outlined, "should" should be interpreted the same as "must"?

You don't comply with TDG, only regulations, hence 'should' allows you to achieve the regulation by an alternative method.
TGD's are industry best practice suggested to achieve it

correct but the designer or installer must be be able to show documentary proof of compliance if they deviate from the TGD,s

Installed as per certified (CE marked) appliance in accordance with the manufacturers instructions.

and you will always find on the manufactures instructions something similar to this which is taken from ariston
Benchmark places responsibilities on both manufacturers and installers. The purpose is to ensure that customers
are provided with the correct equipment for their needs, that it is installed, commissioned and serviced in
accordance with the manufacturer’s instructions by competent persons and that it meets the requirements of
the appropriate Building Regulations.
