How do EnerWorks solar collector and appliances compare to evacuated tube technology?
EnerWorks’ patented solar thermal appliances use flat plate collectors with very low flow, freeze protected heat transfer fluid in the collector and high efficiency brazed plate heat exchangers in the energy pack. The EnerWorks’ residential collectors’ proprietary overheat protection (patented) keeps the collector temperatures under 120C (248F) when the hot water tank is fully charged. The result is low system pressures and no degrading of the heat transfer fluid. Evacuated tubes can reach stagnation temperatures of +300C (572F). These temperatures can cause overheating, high system pressures and breakdowns to rubber seals and vacuums EnerWorks collectors have been tested by third parties such as Florida State Energy Center (FSEC). The EnerWorks residential collector has a FSEC BTU rating of 786 BTU’s per sq ft. The leading brand of evacuated tube collector has models with performance ranges of 634 to 785 BTU’s per sq ft. The EnerWorks commercial collector has about a 10% higher rating
