Water heater accessories: RWT 1-110D

By using a built-in finned tube heat exchanger, it is possible to indirectly heat a storage tank with a flange and thus retrofit or convert it to a coil storage tank. The heating medium can be heating water from alternative energy sources such as solar systems and heat pumps, but also from district heating and conventional boilers.
