Heating a pool with cheap, unglazed plastic panels are often a comparatively straightforward and low price project you’ll do yourself. though these black plastic panels area unit less economical per area unit than high-cost, high-efficiency panels, they’ll need less energy to manufacture and transport than panels victimization steel, aluminium, glass, or copper. This article focuses on how do i install solar panels for heating the pools.
First, take into account on climate. Do you have area for solar panels to receive direct sun most of the day? Can you take away the panels before air current storms and maybe every winter? Can the reduced water flow still clean your pool or is running your pump for a lot of hours acceptable?. No previous designing will substitute for the expertise of making an attempt it out.
Install a 3-way pool valve when the pump and filter (in the come line) thus water are often directed to the panels or to the pool (bypassing the panels). Correct pool valves aren’t low-cost, however they never block the come flow and may be adjusted to direct all, part, or no water through the panels.
Install a T pipe fitting close to the 3-way price within the same come line on the pool aspect. Water coming back from the panels can renter the come line below the valve.
Plastic panels are available in many sizes, however 2’x20′ is common. Purchase no fewer than 2. every panel prices roughly $150. you will need to undertake 2 before adding a lot of. Enough panels to equal the realm of your pool would be ideal, if you have got the area for them. associate degree 18′ diameter spherical pool contains a expanse of concerning 254 square foot / forty square foot per panel = half-dozen panels. however fewer panels area unit OK and it should be best to stay your investment modest till convinced that each one the issues and edges are worthy. a lot of panels need a lot of pump power, thus this can be another thought you’ll perceive higher when you have got tried 2 panels.
Fastening the panels to the roof could also be your greatest challenge and a reason to think about putting them on the bottom. Use stainless-steel hanger bolts ordered on the web, if your native hardware doesn’t carry them. Take into account your roof rafter spacing and find hanger bolts slightly wider than the 2-foot breadth of the panels. A generous dob of roofing compound or “tar” around every hanger bolt is needed to forestall leaks.
Connect the panels to every different and to the union fittings. Pay specific attention to that finish of the panel pipe is IN or OUT, in order that the water flow can perpetually be getting into IN and exiting OUT. Air is cornered within the panels if they’re put in backwards. once panels area unit put in on a slope, the OUT finish of the panel ought to be higher.
After the pipes area unit connected, activate the pump. Check for leaks. in theory, the larger the flow, the a lot of economical (because the cooler water within the panels absorbs a lot of heat from the sun). You’ll most likely notice that the water coming back from the panels is simply 2 or 3 degrees higher; however over a amount of daily this can heat your entire pool by many degrees.
If you reside in a part that experiences sub zero temperatures make certain to put in a drain at the bottom purpose of the system or arrange to pressurize the system with air to forestall freeze harm within the winter.
A controller system is often purchased for around $400 which has temperature probes, valves and actuators to change the system.
