Vaillant Ecomax Pro 18E/Ecotec Plus Heat Exchanger 14cm – Refurbished | Part No. 065180

Reduced heating output, temperature fluctuations, or boiler efficiency loss on a Vaillant Ecomax Pro or Ecotec Plus boiler are frequently caused by a degraded or blocked main heat exchanger. This critical component transfers combustion heat to the central heating water circuit — when it deteriorates, efficient heating cannot be maintained. The Vaillant Heat Exchanger 065180 (14cm, Refurbished) is a professionally refurbished direct replacement covering the Ecomax Pro 18E VU 186-0, Ecomax Pro 28E VU 286-0, Ecotec Plus 415, Ecotec Plus 428, and Ecotec Plus 438 series, restoring efficient heat transfer and reliable boiler performance.

This refurbished unit has been cleaned, inspected, and tested before dispatch. Please note the size is 14cm — confirm this matches your existing heat exchanger before ordering. Supplied with a full 12-month warranty.
