The theory I use is to put as many sq m on the roof as possible . The benefits are it will extend season at both ends & is cheaper to run as it will reach your desired temperature earlier then pump will be off . I used the glass panels with rubber tube years ago . It was a major fail . On a 45deg summer day all the rubber melted . I had to replace with moulded pvc ones. The fact they still sell them must mean this is no longer a problem but I would never use them again. As for general info . If pool is under 20000 litres I generally recommend gas . The advantage is it can heat a pool in a short period of time . I generally spec it to heat pool to 30 deg in middle of winter in 4 hrs Autum / spring in 2 hrs . The bigger the heater the more it costs up front but the lower running cost . A classic example is a customer with a 9000 litre pool wanted instant heat . We fitted a 450mj gas heater . In doing so we needed to fit a new meter & bigger gas pipes . The end result was pool. Heated from 17-32deg in 20 minutes . The cost to heat is minimal . If you plan to use pool every day a heat pump will work out the most efficient . It will work a lot better with a blanket but if aesthetics is important a blanket is ugly. When buying a heat pump the sizing manufactures recommend is about half the size you really need . The other problem in comparing a heat pump is they aren't uniformly rated .a 5 kW in one brand can be the same as a 13kw in another brand . They rate output at ambient temperature . A heater rated at 5kw at 6deg could be sold as a 13kw at 35deg. . If your in a cold climate you need one rated to work at under 12deg . A lot don't . You also need one with a auto defrost . When. Choosing a heating system the questions are 1-when do you want to use it 2- do I have natural gas ( is it a option) 3- do you want to spend more upfront or ongoing ( another part to this is how's long you plan living there for . If selling in a few years efficient heating won't add value to property) 4- do I want instant heat Re: Pool heating 8Sep 13, 2015 1:53 pm leni I'm in Perth and will go for solar rubber tubing style. I'm a tight ***! The rubber matt is fine if 1- there area no cockatoos around 2- no trees which can drop sticks on it 3 - no strong wind to blow it off the roof 4- no hail storms 5 -you don't mind regularly climbing on the roof with a knife & joiners 6 - your roof isn't visible from the ground Otherwise the panel systems generally have a 20 year warranty , and are about 20% more efficient . They do cost about 20- 30%'more but well,worth it Cheers Re: Pool heating 9Sep 13, 2015 2:26 pm Thanks wheeliworks, Some really good info, a lot to think about. I'm thinking of the polypropylene panels from either Zane or Heliocol, Heliocol also make the sunX which I guess is kind of semi glazed but these need to drain out so no good for me. The OKU look OK but I'm worried about all those extra hose connections. If I didn't have a flat metal roof with box gutters I would seriously consider the rubber mat. I'm a bit of a tight ***! too, we all like to save a few $$ ah. I think the ruber mat maybe best suited to tiles, replacing a bit of gutter isn't too hard if it does leak. Re: Pool heating 10Sep 13, 2015 3:02 pm I think on those criteria we will actually be OK! Will consider the panels too!
