This Vaillant insulation is for use in the heat exchanger ecoMAX VU (condensing) and ecoTEC VU (condensing) boilers.
The heat exchanger transfers heat from a boiler’s burner to water.
A primary heat exchanger is found in all boilers, using heat from a burner to raise the temperature of the water in the system while a secondary heat exchanger is present only in combis and allows the heat to be transferred between closed systems.
