Viessmann heat exchanger is compatible with Vitodens boilers. It comes with two nuts and four gaskets for a easy installation. The heat exchanger transfers heat from a boiler's burner to water. A primary heat exchanger is found in all boilers and uses heat from a burner to raise the temperature of the water in the system. The secondary heat exchanger is only found in combis and allows heat to be transported between closed systems.
