Model P118330 -PV Powered Solar Pump

Typically, a solar water heater will run for 2,500 hours per year in mid-latitude countries consuming 80 watts of grid electricity during operation. Using the Thermo Dynamics Solar Pump™ in place of a grid-connected circulator and solar controller will save 200 kilowatt-hours (kWh) of purchased electricity each year. This translates to 2,000 kWh over the 10-year warranty period of the pump, or 4,000 kWh over the expected lifetime of the Solar Pump™. These savings will more than cover the additional cost of the Solar Pump™ relative to a standard "plug-in" pump, especially when considering the fact that electricity prices continue to rise year after year. Additional savings can also be realized by reducing the tube diameter that connects the Solar Pump™ to the solar collectors. The added pressure drop of the smaller diameter tubing is easily overcome by this powerful little pump.

Installing a Solar Pump™ can also reduce the time necessary to install a solar water heater providing further money savings. The Solar Pump™ is self-priming and will continue to pump anytime liquid is available, regardless of whether air is present. No air separator is necessary nor a charging pump. The Solar Pump™ can provide all the pressure necessary to completely charge a typical circulation loop.

Not only is it economical to use the Solar Pump, but by using solar energy you reduce the pollution for which you are responsible when using a grid-connected pump. To produce 4,000 kilowatt-hours of electricity in a modern steam power plant will result in four tonnes of carbon dioxide emissions into the atmosphere!!
