Solar is cheap compare to under systems, cheap to run etc... Heat pump are very efficient, cost more initially and more running costs. With this in mind, if we install solar pool heating we wouldn't be able to fit solar power on the roof as well. Thus making it wasted space when the pool is off over winter. So we was thinking of the heat pump idea and install solar power panels to combat the power issue. Your thoughts? Our pool will be 8m x 4m Has anyone got this setup? Solar pool heating doesn't need to be put on your roof - it can be fitted to car ports, sheds, patios, pergolas etc. If you go with panels over tubes, because panels are rigid they can be used as a roof on pergolas etc. You can even mount them on framework on the ground if you have space. We compared with heat pumps too and went for solar panels in the end, here's why; Most solar pool heating co's recommend that you size a system based on 80% of the pool surface area if you have a north facing roof. So for an 8x4m pool, you'll be looking at a system of roughly 25.6m2. The panels we went with are 3m x 1.2m (3.6m2) Using the same panels for your pool would mean 7 panels. Being panels, we looked up the their performance testing results at the FSEC website - each of the panels puts out 39,300 btu's (11.5kwh) per day on days when the solar energy available is 5kwh/m2 or more. So basically a 7 panel solar pool heating system puts out 80.5 kWh of heat energy each day that there is more than 5kWh/m2 of solar energy available. For around 7.5 months of the year in Perth, the solar energy available is around 5kWh/m2 or more each day. That's around 225 days each year when the solar pool heating is producing about 80.5kWh each day - it will still produce heat on other days, just not as much. Looking at heat pumps, say a fairly energy efficient one putting out 4 units for every 1 unit of electricity, you'd use just over 20 kWh of electricity each day to do the same job as the solar pool heater. 20 units at current electricity prices ($0.24/kwh) is equal to $4.83 each day. Over the 225 days, the heat pump will cost $1,086.75 in electricity, solar does the same for free! Does anyone have a suggestion for a good hydronic in slab heating speacialist who may be able to help me with an existing system and wether or not it may need a seperator… 0 4887 Hi everyone, Looking for some advise. We are about to build an above ground pool in our backyard. There is a private sewer line running under the pool at 1.6m… 0 11760 Hi, I'm new to this forum so I hope I'm doing this post correctly. Please advise if it's not. I've just bought my place. The inground pool has a marble lining that has… 0 13663 |
