We now sell BEC Solar Controllers for Solar Thermal applications. They are manufactured to our specifications for custom solar thermal control.

The BEC Solar Controller allows the ability to combine multiple heating inputs from solar, geothermal, wood, fossil fuel, etc., with multiple loads from low temperature through high temperature applications.

A multitude of adjustable functions and options are possible using 7 relay outputs and 10 sensor inputs for Pt1000, CS10 and V40. Due to its intelligent and easy-to-understand system configuration and its integrated calorimeter, the controller also offers the control of complex systems with up to 4 weather-compensated heating circuits. For data communication and remote maintenance, the controller is equipped with a VBus, which permits two-way communication between modules, PCs or dataloggers.

Solar Hot Water System for Local B&B

We installed this 5 panel Solar Hot water system along with the solar electric array at the Fountain Chateau B&B in Hustler, WI. We had help this past summer from two interns from Mid-State Technical College in Wisconsin Rapids, Jeff Dillow and Nick Schoenoff.

These five solar hot water panels were manufactured by Bubbling Springs Solar
in Menomonie, WI. The solar hot water is pumped to the solar storage tank via a solar electric panel and DC pump. The pump is a March Manufacturing pump made in Illinois. This system is completely independent of any outside sources of power or fuel for it's operation.
The solar heat fluid is delivered to this 200 gallon insulated solar thermal storage tank with a custom built heat exchanger and should provide up to 60% of this B&B's domestic hot water needs.
