Vaillant Combi Boiler Overview:

There are 3 different Vaillant boiler ranges available within Vaillant’s ever popular EcoTec series. Every boiler included in these 3 boilers ranges is an A-rated condensing boiler, meaning customers can rest assured that they will be receiving a reliable hot water and central heating performance from 1 of the UK’s top boiler brands.


There are a number of different boiler models within each range that have been developed to offer the consumer different options where it comes to central heating output and hot water flowrate – so there’s something for all homes, no matter how big or small.


A overview of each boiler range is provided below for your reference:


2 year warranty in Ecotec Pro boilers

  • Vaillant EcoTec Pro – A very popular range for smaller properties such as 1 bedroom houses, flats and apartments, the EcoTec Pro range offers consumers an A-rated condensing boiler that comes with a 2 year warranty as standard. There are 2 natural gas models models available in the EcoTec Pro range; the Vaillant Ecotec Pro 24 combi boiler and the Vaillant Ecotec Pro 28 combi boiler). LPG fed versions of these boilers are also available.


  • 5 year warranty in Ecotec Plus boilers
  • Vaillant EcoTec Plus – The EcoTec Plus Combi Boiler range is probably the most popular in Vaillant’s EcoTec series largely due to the fact that it is capable of dealing with the hot water & heating demands for a broad range of medium to large sized properties (making it possible to find at least 1 boiler in the range that it suitable for properties with 2-3 bedroom properties with 1-2 bathrooms). There are 4 boiler models in the Plus range, the 824, 831, 837 and 937 models. The Vaillant Ecotec Plus 824 Combi boiler is very similar to the Pro 24 model, but comes with an extended warranty of 5 years rather than 2 years and also has a front flap, helping to hide away the lights and controls. The Vaillant Ecotec 831 Combi boiler and Vaillant EcoTec 837 Combi boiler are probably the biggest sellers as they have stronger flowrates and central heating outputs, making them ideal for 2-3 bedroom properties. The Vaillant Ecotec 937 Combi boiler is a bit different from the others as it offers a higher level of hot water performance due to the integrated 'actoSTOR' storage tank. Like the Pro range, the Plus Combi boiler range runs off a natural gas supply but is also available as a LPG version. EcoTec Plus boilers currently come with a 5 year warranty as standard and can be delivered FREE of charge to your door within 2 working days, in many cases the next working day.

  • 5 year warranty in Ecotec Exclusive boilers
  • Vaillant EcoTec Exclusive – For larger properties of 3+ bedrooms and 2+ bathrooms it is worth looking at the EcoTec Exclusive range. With large central heating outputs and strong flowrates, the Vaillant EcoTec 832 Combi boiler and Vaillant EcoTec 838 Combi boiler (both natural gas and LPG models) are able to deal with a high demand for hot water & heat. EcoTec Exclusive boilers currently come with a 5 year warranty.
