Caleffi is proud to announce its SolarFlat Collectors , Models NAS10406, NAS10408 and NAS10410, have been accepted by the ecoENERGY for Renewable Heat Program sponsored by the government of Canada.Solar thermal collectors are used to capture energy from the sun and efficiently transfer solar energy to heat the solar fluid in the primary circuits of solar heating systems. This heated solar fluid is circulated through a heat exchanger, thus heating domestic water, which is stored in a suitable tank . This heated water is then delivered to a conventional water heater for final heating, if required, or direct use.
