A Vaillant heat exchanger suitable for ecoTEC VU (condensing) and ecoMAX 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. We carry over 300 of the most in demand parts in-branch and stock over 25,000 spare parts available for next-day timed delivery.
