Yeah I was also thinking about importing in some solar heating unit from oversea..
As to the price tags..I was doing some home work to day, i would needed 3x 2.400 panels of 25mm/min.
Mouldford Plastics $$1,200 per sheet,
Lee engineering labour welding acrylic $$3,000
$4,500
The rest such as block work and tiling are my specialty :yaw1:
The true is since i cant have an out door pond for my midas, i was thinking a large tank for the group :facepalm:
