Let the local pre school kids use it for swimming lessons. They dont leave the pool to pee so it will be warmed for free.

Hope this helps.

Just re-route your filter pipe thru a sh!tload of black pipe on the roof. Could be free if you scrounge

I've worked on a couple of projects where the clients have incorporated their pool heating with their heating and hot water. Either hydroponic or geothermal are the best options albeit expensive. I would think that living in WA you wouldn't need heating?

I fitted a solar system to our 50,000 litre pool a couple of years ago. Contacted Waterco in Balcatta. They put me onto their guy, John I think his name was.
He sold me the complete DIY set up for solar, including auto control but minus pump for around $1600'ish (he also installs)
The efficiency of the system, as I see it, relies on how much pipe, or heat exhanger you can get onto your roof. I was told that you need to have the same surface area of your pool as a minimum....not sure it's worth it if you don't have the roof space.
I have a pool surface area of 40m2 and have an exchanger area of approximately 55m2.....pool is a 'well toasty' 30 degrees from early November through to April/May.
The pump obviously runs more in the relatively cooler months but I've never really noticed a difference in our summer power bill after the install.
The only complaint I have is with the heat exchanger manifolds. They occasionally leak through the rubber grommets. I then have to haul my lazy backside up onto the roof and replace. Not a big deal though.
I also priced up gas heating at the same time......the expense of the unit put me off....think it was around 8 to 10K.

Get yourself a solar pool blanket works a treat. Keeps the leaves and crap out, stops evaporation and saves on chemicals. But remember in summer circulate the pool for about half an hour before getting in otherwise you might get a free skin peel coz the top 1/2 meter gets bloody hot...

I have a pool approx 38000 lt , I have the simple black pvc pipes on my garage roof.
We live in Wollongong and the pool was 30 deg today.
Before the hard knobs get on and say ( I wouldnt swim in that 21 is hot enough ) phfttt to that.The cook wont go in under 30...
Hell I got it to 35deg once....that was a touch too hot even for me.
