Vaillant Ecotec Plus 938 ErP Combination Boiler 0010021827


Vaillant Ecotec Plus 938 ErP Combination Boiler 0010021827
The Vaillant ecoTEC plus 938 is a solution for large 3-4 bedroom properties with more than 2 bathrooms. The Vaillant ecoTEC plus 938 also features an innovative integrated hot water storage device at the back of the boiler. This special feature means the product is capable of delivering up to 20 litres of hot water per minute (significantly more than could be delivered by a traditional combination boiler), without the need for you to install a separate hot water cylinder or cold water tank in the loft.
