install new cold water tank.

[aga memnon]

Hello wondered can anyone help with a query? Fitting a 50 gallon coffin tank in roof eave, (dormer bungalow) but because of house design having to use eave on opposite side of house to hot water cylinder about 7 metres away.( the eave on the hot water cylinder side is to small). Is there any problem with this other than the Hassel of extra pipe work? Many thanks for any answers.

Won't Make and difference, pressure is dictated by "head of water" so as long as it's the same height it will be just the same.

Keep your feed pipe to the HWC on a gradient downwards to avoid airlocks.

A decent gradient at that. A 1:100 is ideal (70mm on your 7m run)

Have you checked if the floor can take the weight of the new tank. it gets heavy with 50 gallons of water in it. Maybe the other side where the old tank was had the floor reinforced.
Just a thought.

Hi, About cold water tank in eave, the tank is a 65" long coffin tank and will span weight over 5 8 x 2" joists do you think this I'll be OK?

50 gallons weigh 500lb (about 36 stone)

Thanks for reply, so I am hoping that it should be OK about same weight as double bed with two people or a large bath with one person. Should have said its a new build so building control won't be long telling me to change it. Cheers.
