Vaillant ecoTEC plus combination store combi boiler

The solution for larger homes

  • High performance, control and efficiency
  • Integrated hot water storage device at the back of the boiler
  • Hot water within 5 seconds* and up to 20 litres of hot water per minute
  • A wide range of heating control options, from our simple boiler timer right up to our vSMART™ smartphone app
  • 5-year guarantee as standard, with 7 to 10 years available when you book a Vaillant Advance installer

If you have a larger home with high hot water demands, but you’d prefer not to install a hot-water cylinder or cold-water tank, the ecoTEC plus 38kW combination store is the boiler solution for you.

Our goal is always outstanding performance: low energy consumption for hot water and central heating – and lower fuel bills for you. The ecoTEC plus is smart: when it’s on it can produce 20 litres per minute, significantly more than a traditional combination boiler could deliver.

But when it knows you don’t need as much heating power, it can drop to using 16% of its maximum power saving on fuel and money.

Because we know that’s what you want from your boiler. You want it to be efficient, easy to use, reliable and quiet.

Its straightforward backlit display, its stainless-steel heat exchanger, its premium components, and its Quiet Mark accreditation all mean that with the ecoTEC plus you can go tick, tick, tick and tick.
