Solar powered Water Heating
Solar water heaters—also called solar domestic hot water systems—can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use—sunshine—is free.
We now offer the best proven technology in Solar Thermal Hot Water Heating Systems. Learn how you can make an investment in this renewable energy resource today! Give us a call and in just fifteen minutes see if your home or business is a good candidate for this renewable energy opportunity.
The Sunward System is designed to work in any climate. The system does not heat the water you use for washing and bathing directly. Instead, a fluid called Glycol (a non-toxic, food-grade anti-freeze) is circulated through the Sunward System. The Glycol captures the sun’s heat and transports that heat to the 'Heat Exchanger' unit where it is transferred to water and stored, ready to supplement your existing water supply.
The Heat Exchanger unit allows the transfer of heat from the Glycol to your water supply without the two mixing.
The entire Sunward System has only one moving part — a magnetic-drive pump, to circulate the Glycol. Unique to Sunward, this pump is powered by small Photovoltaic (PV) solar panel, so the system requires no external power source.
Each Solar Collector is a sturdy, glass-paneled 4' x 8' box, which is insulated. Placed at the proper angle — on your roof or on the ground — the Collector efficiently captures the sun’s energy.
As sunlight travels through the glazed glass it heats the tubing. Inside the copper tubing is a heat transfer fluid called Glycol. This non-toxic food-grade anti-freeze absorbs the heat from the sun. The fluid is then pumped to a Heat Exchanger where the heat is transferred to your water supply.
Once the sun’s energy has heated the Glycol fluid in the Solar Collector, the fluid is pumped to the Heat Exchanger.
The Glycol travels from the Solar Collector to the Heat Exchanger through our exclusive Sunward Micro-Tubing. This 3/8" copper tubing is flexible, so it can be easily routed from the Collector to the Heat Exchanger without the need to cut solid pipe and solder joints at every turn.
The Micro-Tubing is pre-insulated at our factory, which greatly reduces the amount of labor you'll have to perform during installation.
The Heat Exchanger takes the heat that’s been absrobed by the Glycol and transfers it to your water supply.
Inside the Heat Exchanger is more than 130 feet of 1/4" copper tubing which is coiled inside a 4" diameter cylinder. Solar heated Glycol flows though this mass of copper which is surrounded by potable water. This water absorbs the heat radiating from the copper tubing and becomes hot water.
The hot water then travels into the Sunward Storage Tank, where it’s stored until needed.
The Sunward Solar Storage Tank holds the water that’s been heated in the Heat Exchanger.
Hot water from the Heat Exchanger is fed into the top of the 80-gallon Sunward Storage Tank. This pre-heated hot water is available on demand, and during sunny periods you'll enjoy 100% solar heated water.
When the sun is less intense your water may only get partially pre-heated, but your existing water heating device will kick in to finish the job. The good news is that even if there is only enough sunlight to heat your water a few degrees, your existing system will use that much less energy.
The glass-lined Sunward Storage Tank is well insulated, so your supply of solar heated water will retain much of its heat well after the sun goes down.
