Solar water heating panel without the insulating box. You can make your own box, or you. Can place the panel on the roof without the box if you live in the south. In a good location these panels (we have more than one panel available) can pay for themselves by the end of first year. Size: 40″ x 40″ x 1. Absorber area: 10 square feet. Made of copper tubes and aluminum fins with ultrasonic welding between the tube and fins, and highly efficient. (metals conduct heat better and last longer than plastic). Inlet and outlet copper tubes are size 3/4. (outer diameter about 7/8″ and 0.03″ thick). Standard 3/4 copper or cpvc or pex pipes and fittings. If you use compression fittings or push-fit (sharkbite), no soldering needed. Two panels together can heat a 40 gallon water tank up to 130 degrees f. Panels’ internal temperature can reach over. Temperature (very hot) in the insulating box when the water inside is. These panels can also effectively heat a spa, and warm up a swimming. Pool by 15 degrees (depending on the pool size and the location) to extend swimming. Season and cut heating cost. Compatible with electric or gas hot water heater, pool or spa heater. Work under normal house water pressure. Each panel is tested up to pressures of 15 bar (217 psi). Panels can be connected to a water (heater) tank with or without a pump, depending on the locations of the tank and panel. If the panel is positioned below or level with the tank, no pump needed. If panel is positioned above the tank, a circulating pump needed. Here is how it works without a pump. The fins with tubes of the panel absorb heat from sunlight through the highly absorptive coating, and water inside the tubes heats up. The inlet and outlet of the panel are plumbed respectively to the. And hot water outlet of the storage tank (as shown in the figure above). It forms a loop. The heated water moves from the panel to the storage tank through a process called thermosiphon. Thermosiphon hot water rises as cooler water sinks. Heated water becomes less dense. Results when water heated in the panel expands and rises. Causing the water in the loop to circulate. Cooler water is pushed out of the bottom of the tank and into the bottom of the panel, heated by sunlight and rises. Once circulation starts, the process continues all day. This natural convection action (similar to air convection) is a neat way to move heat around without a pump. The storage tank can be a water heater tank, a hot tub, or any water tank with correct connection and insulation. Not recommended for use during freezing weather without antifreeze protection. Panels need to be drained during freezing weather if no antifreeze is inside. On rainy or cloudy days, electricity or gas needs turned on as backup. Panel with insulating box can be used for supplemental winter space heating. When connected to a heat exchanger, a radiator or radiant floor. As shown in the figure above. You may consider using propylene glycol (non-toxic antifreeze liquid) in the collector-radiator loop, mixed with water in concentrations that will prevent damage from freezing to the lowest anticipated temperatures in your region. These panels are ideal to use as supplemental heat source to the existing wood furnace or gas boiler. The higher temperature of the liquid going into the boiler, the less wood or gas will be burned. These highly efficient solar thermal panels are ideal for many applications: residential. Water heating & s. Homes, mobile homes, cabins. Commercial water heating & s. Offices, clinics, warehouses & factories. Outdoor hot water (spa & pool, farm & ranch).
