Solar Hot Water System Using an AquaStar 125BS Tankless Water Heater in solar applications to give you hot water when the clouds are gone or when they are over head Return to AquaStar Main Page The temperature of stored solar-heated water varies a lot. To remain comfortably hot, it must be reheated. Unlike the storage tank which maintains the stored water hot, the AquaStar tankless solar model is specifically designed to boost solar-heated water only at the time that hot water is being used, and to do so using only the minimum energy required for the temperature rise required, thereby offering maximum efficiency. AquaStar solar model 125BS is the perfect backup to preheated water, be it solar-heated or otherwise.
