Boilers in the Vaillant ecoTec Plus series

The ecoTec Plus series offers 5 different model options, each suitable for different homes and different central heating demands. Here’s an outline of the boilers featured in the range:


ecoTEC Plus 825

This light and compact 25kW boiler is typically best suited to small homes thanks to its flow rate of 10.5 litres per minute. Like the other boilers in the range, this unit is Quiet Mark accredited.

ecoTEC Plus 832

With exactly the same size and energy-efficiency rating (A) as the 825, the 832 (32kW) could be an ideal choice for small-to-medium homes with an average hot-water demand.

ecoTEC Plus 835

With this model, Vaillant managed to pack even more power into the same unit size with the 835 (35kW). It could supply homes with 14.3 litres of water per minute, with the same level of energy-efficiency as its sister boilers.

ecoTEC Plus 838

This 38kW unit is slightly bigger in terms of dimensions and boasts a flow rate of 15.9 litres per minute to potentially suit the needs of larger homes with higher demands for hot-water.

ecoTEC Plus 938

The largest unit in the ecoTEC Plus range is the 938, which, similarly to the 838, also has an output of 38kW, but offers a flow rate of up to 20 litres per minute in a unit of 720mm high, 440mm wide and 600mm deep.
