Pumping into my current outdoor pool... which is 6,500L i dont really think i am going to make much impact... but we will see.
Due to the length i found it easiest to just lay the entire hose out... prettymuch around the house. and then start to coil it up. I went as tight as possible before it kinked.
You will want atleast two people to give you a hand for either keeping the coils snug and tight / pulling more hose etc. Aswell as grabbing various sections of pipe and holding them so you can tape them together.
Not really until the end of the coil we came up with a reasonable way to bind them together... If you try and tape from the inner coil to the outer, it will just buckle unless you brace it.. i couldnt be bothered doing that. I found that by binding 3 - 4 together in say 1/4 or 1/5th segments then adding another few coils and then binding 3 - 4 more segments. but this time bind them between the previous segmented areas and include one of previous pipes that has already been taped it was much more stable... I'll draw a quick diagram because that barely makes sense to me reading that back!
put a couple of elbows on, both ending in the same direction as i want the pipe to end up.
and finally, chucked up on the roof, draping down to my pump and pool. To get it up there we used an old piece of MDF board that was a dartboard backdrop or something... and just raised it and slid it off like a pizza.
It took about 5 mins for the water to make it up and around the 90m or so of coil and back down. (10,000L per hr pump) it was bloody hot when it came out!
i'll monitor temps and see if it makes much difference to this large volume of water.

The next step up from this that I sometimes see as an energy auditor is the evacuated metal piping with a heat exchange for hot water showers.
Edit: Might be worthwhile looking into a really basic heat exchange system if you're gonna pump tank water though those pipes. Might save you one day when a fitting goes or the pipe dies or the whole thing blows off in a storm. Nothing fancy just not copper pipes if you're gonna have invertebrates.

Yes that is true as well... but my tank is only 1000L so, it should work fairly well... only thing is that the weather is warming up pretty quickly as well... well let me start thinking about how to get this done first...

Do you think something like this could be used with a pump connected to the heating terminals? LCD Digital Temperature Controller
Thanks, Kieran.
