The ecoTEC pro 28kW combination boiler is a reliable, high-efficiency solution for homes with smaller heating and hot water needs. Hand-built in Vaillant's award-winning Derbyshire manufacturing plant, it combines Vaillant’s renowned quality and performance with a simple, cost-effective design.

Why Choose a Combination Boiler?

Combi boilers provide heating and hot water on demand, without the need for a separate hot water cylinder or cold water tank. This makes them an ideal choice for smaller homes, where space and energy efficiency are key considerations.

Features:

  • aquaCOMFORT technology – Delivers hot water quickly at a constant temperature, reducing water wastage.
  • Fully modulating low NOx burner and fan – Optimises performance for greater efficiency and lower emissions.
  • Compact dimensions – At 720mm x 440mm x 335mm, this boiler offers flexible installation options, even in tight spaces.
  • Hybrid-ready – Compatible with aroTHERM plus air-to-water heat pump hybrid systems, making it a future-proof heating solution.
  • Highly efficient and economical to run – Achieves up to 89.5% efficiency (SAP 2008/2012) for reduced energy costs.
  • Flexible flue options – 60/100 push-fit flue system, with an 80/125 adaptor for longer flue lengths and more installation flexibility.
  • Boiler Plus compliant – Works with sensoHOME, sensoCOMFORT, and VRC 700 for weather-compensated heating control.
  • Patented stainless steel heat exchanger – Ensures highly efficient heat transfer and superior durability.
  • Built-in two-stage frost protection – Keeps the system working optimally all year round.
  • Easy installation & maintenance – Front-facing component access and removable side panels make servicing straightforward.

Guarantee Options:

  • Standard 2-year guarantee out of the box.
  • Upgrade to a free 7-year guarantee when registered through Vaillant Advance.
  • Optional 10-year guarantee upgrade available for £150 + VAT.
