A super insulated tank, with a heat exchanger built into it. Hot water from a boiler is pumped through the exchanger, which in turn heats the domestic hot water. This creates an abundance of hot water quickly, at an economical price.
An indirect water heater circulates water through a heat exchanger in the boiler. This heated water then flows to an insulated storage tank. Because the boiler does not need to operate frequently, this system is more efficient than the tankless coil. In fact, when an indirect water heater is used with a highly efficient boiler, the combination may provide one of the least expensive methods of water heating.

An insulated storage tank that contains an internal heat exchanger for heating the domestic hot water in the tank.
A separate water storage tank that contains a coil supplied with hot water from a boiler. The coil transmits heat to the water in the tank, which is then piped for domestic hot water use.
A type of water heater that circulates water through a heat exchanger in a boiler. The heated water then flows into an insulated storage tank.
