Apricus Evacuated-Tube Solar Panels in Pasadena Annapolis & Crofton MD(Thermal solar heating) The Apricus Solar Collector or Solar Water Heater is a device that absorbs thermal energy from the sun and converts it into usable heat. The heat is normally absorbed by water, or a freeze resistant water mix, which can then be used to supplement hot water heating, space heating and even space cooling via use of an absorption chiller or dessicant cooler technology.Key features of the Apricus Solar Collector design.Internationally certified productReliable, efficient, twin-glass evacuated tubesCopper heat pipes for rapid heat transferEasy plug-in installationMaintenance FreeSuitable for mains pressure water (up to 8 bar/116psi)Corrosion resistant silver brazed copper headerAll stainless steel frame (439 grade SS)Black or Silver aluminium casingStable solar conversion throughout the day (tubes passively track the sun)The perfect solar collector for domestic solar water heater systemsIdeal for commercial solar water heating applicationsComprehensive 10 year limited warrantyThe operation of the solar collector is very simple.Solar AbsorptionSolar radiation is absorbed by the evacuated tubes and converted into heat.Solar Heat TransferHeat pipes conduct the heat from within the solar tube up to the header.Solar Energy StorageWater is circulated through the header, via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by 5-10oC / 9-18oF. Throughout the day, the water in the storage tank is gradually heated.[Read more about Apricus Solar Collectors on the Apricus website]
