    Fortunately we don't have any stairs yet, but we'll need to lift it about 6m straight up. Any suggestions on the best method?

    Lidl chain hoist. Or two.

    Used my two a lot putting posts and purlins up with no problems (at least, none which can be ascribed to the hoists). For something like your heat store using two hoists in series might just work or using one to lift it so far, rope it off securely, extend the hoist again and lift further. Or, if you actually need to go a bit further than the reach of two, use a hoist to lift it a metre or so, push trestles under, then lift again with two hoists.

    Depends a lot on what you've got to tie it off to above.

    What is going to keep it up once it is filled with water? I assume 300kg is the empty wight.

    Sheer legs placed over the stairwell, then a cable over a tackle, towed outside by a jeep...

    I made my own stairs for our loft conversion and did the lift with rope and two pulleys using jumars ( these are devices used in climbing that alow a rope to be pulled through it but jam to stop it coming back.) all slung from an RSJ in the roof.

    Chain hoist - and replace the chain with one long enough to do the lift in one go without the need to do series lifts.

    you could hire a genie lift if you don't have sufficient structural support above the stairwell to dangle 300kg from. I think the heay duty job will lift 300kg to more than 6m. I know HSS hire them out, possibly others. The question would be whether the lift can be manouvered into the stairwell, though I think they do fold up to an extent to help with access.

    Make sure you follow any lifting instructions. It's very tempting for people to lift it by the pipe connections but that's usually not allowed.

    That's very helpful, thanks everyone. I think the most tricky but will be the transfer across once we're in the attic. Not sure how to simultaneity lift it and move it sideways.

    If it is tall and narrow, rocking it from side to side and rotating it a bit this way and that at the same time can work well, a bit like a penguin walking. I've an idea this method may have been used for the Easter Island statues, or maybe it was the Stonehenge stones - anyway its how I move heavy garden furniture single handed. Alternatively, I've shifted heavy machinery with some ease by sliding it along greased strips of steel.
    300 kg you say - must be a very big tank?

    You don't.. you lift the weight, then build something under it(put some joists across the hole), lower the load onto the joists, then move it horizontally..

    Or you rig up some scaffolding, clamp a small RSJ on top, and suspend a block & tackle from a beam trolley. That way you can shift the load sideways as well as vertically.

    Have you thought of getting a Sunamp?

    What is the advantage of a sunamp? Is it lighter?

    Yes, and smaller.
    I think the newer ones can be broken down into manageable section that are easily moveable.

    You also get the advantage that they have lower heat losses and with a bit of plumbing magic, you can switch units in and out of the circuit as and when needed.

    You do need to make sure you have a system design suitable for a Sunamp. They're not a plug-and-play replacement for a thermal store.

    True, but they have a good technical department and are open to ideas.
    First thing to do is work out the price, they are relatively expensive compared to a large bottle of water.

    I shifted my Dad's Bosky. Bought a couple of 8 x 4 steel sheets (very thin. Oiled between and slid, pulled one out, slid ditto etc.

    Thanks all! I think we'll stick with the heat store for the time being as we've reinforced the structure to take its weight and it's probably the more economical option right now.

    Scuse my ignorance but what kind of empty tank is this, that weighs 300kg? Got a link?

    Good guess Ed!

    Well we managed it. It was closer to 500kg in the end. We hoisted it vertically up the stairwell with a hoist on a scaffold frame, then slid a cover with scaffolding poles underneath. It would have been easy if the hoist was able to lift it all the way, but because the hoist was a little too low, it was about 200 mm short. We had to manually lever it that last bit. Once it was up, it was relatively easy to manoeuvre. Thanks your all your advice!

    Think I'd have put a pallet truck under the scaffold and lifted the whole lot for my extra 200 mm!

    You must have some faith in your ceiling joists to have 2.5tons of hot water suspended above your living quarters, I think I might have dug a hole somewhere and dropped it in..
