System with On-Demand Tankless Water Heater

In this arrangement an "on-demand" gas hot water heater acts as a supplemental water heating system. Water heated by the collector is stored in a tank before moving into the on-demand heater and then into the house. While more expensive than conventional hot water heaters, on-demand heaters are more efficient and rapidly heat only the water that is being used. "On demand" hot water systems are also known as tanless water heaters.
