    Can I move the water cylinder to the attic?


    I own a top floor apartment with an attic. All electric with a large cold-over-hot water cylinder and pump in the hotpress. I need to move the water cylinder and pump, in order to convert the hotpress into a soundproof booth.

    We'd like a new cylinder too, since the one we have only provides enough hot water for 1/3 of a bathful. It is probably very unwise to mount a cylinder on the joists, as they are not thick enough. There are blockwork walls at both ends of the attic.

    Could a horizontal cylinder be mounted on a blockwork wall safely, if the right fixings and brackets are drilled far enough in?

    "Hi, Yes you can move the cylinder and the pump into the attic. You would have to use 18mm or 22mm ply to strengthen so you can rest the cylinder and pump. Obviously, you would have to adjust all the pipe work for it."

    "You could get an unvented cylinder that runs off the cold mains supply. You can use a horizontal cylinder, however, will be floor mounted so if with a horizontal or vertical cylinder would need marine ply across at least 4 joists to support the weight.
    Hope this helps."

    "It’s possible, but with the weight of a tank once full, personally I wouldn’t rely on wall fixings alone. On a reinforced base to span the weight above the joist and also the wall fixings would be the ideal solution if possible. Then you are covered.

    Also as suggested in a previous answer. Perhaps consider a pressurised system if the properties mains water, flow rate, pressure and pipe sizing meets the criteria.

    Hope this helps.

    "Can’t see why not, providing the roof trusses are strong enough, they might need strengthening.
    Also might be worth considering a pressurised tank as you will lose the gravity advantage
    I’m not a fully qualified plumber best to ask them about water tanks and pressurised cylinders, think they are a good idea, most of mainland Europe use them."
