Designed and manufactured by Vaillant, the ecoTEC Plus 637 is a condensing system gas boiler that would suit the heating and hot water demand of larger homes.
What’s the output rating?
An output rating of 37 kW makes the ecoTEC Plus 637 most suitable for larger homes with 2+ bathrooms with a higher demand for heating and hot water.
How efficient is this boiler?
The Vaillant ecoTEC Plus 637 features a 94% seasonal efficiency rating, making this an ErP A-rated boiler for heat.
Is a system boiler right for my home?
A system boiler directly heats the central heating system and domestic hot water for a storage cylinder. Most of the important parts of the hot water and heating system, such as the pump and expansion vessel, are built into the unit itself, helping for a quick and clean installation as well as a faster response to demand for heating and hot water. Plus you don’t need to have a feed and expansion tank in the loft, which you would with a regular boiler.
Will this boiler save you money?
As an energy efficient unit, the ecoTEC Plus will reduce your energy bills and your carbon footprint. Plus, when you don’t need as much heating power, it can drop to using 16% of its maximum power, another way it helps to save fuel and money. As well as this, it’s easy to install which will reduce the costs of installation too.
Where can the ecoTEC Plus 637 be installed?
As a compact wall-mounted boiler, measuring only 270mm x 440mm x 338mm (HxWxD), the ecoTEC Plus 637 can fit into a standard cupboard. Thanks to the frost protection feature, it can be installed with a loft or garage too.
What are the key features of the Vaillant ecoTEC Plus 637?
The Vaillant ecoTEC Plus 637 includes frost protection to keep it running through the winter, a straightforward backlit display, a stainless steel heat exchanger, premium components and Quiet Mark accreditation. There’s a wide choice of app controls and constant hot water, its vaillant vSMART app based control so you can control your heating while on the go.
Does this range include any other options?
As well as an output rating of 37 kW, there are smaller output ratings of 12 kW, 15 kW, 24 kW and 30 kW for properties that don’t have such a high demand for heating and hot water.
How long is the warranty period?
Featuring a 5 year warranty as standard that can be upgraded to 7-10 years when installed by a Vaillant Advance installer, you’ll be well covered by Vaillant long after the installation.

Had this boiler fitted just under 2 years ago by a contractor who recommended Vaillant. Well since then have had trouble with it, Vaillant have been out (due to the incredible noise it was making) changed the mass flu sensor and gas value. Now the noise is so great that the neighbours can hear when it is on. I was told by Vaillant to get a system bypass fitted and see if that works. Well do you think you can find a plumber who repairs or services Vaillant boilers it's virtually impossible to find! I have been told by several people that Vaillant aren't any good and that I should have had a Worcester fitted. Just wish I had known this when we did our extension, the big problem is there are no proper reviews to read anywhere!
