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.
How efficient is the ecoTEC Plus 637?
The Vaillant ecoTEC Plus 637 features a 94% seasonal efficiency rating, making this an ErP A-rated boiler for heat. This means that it's a highly efficient boiler that could help to lower your energy bills.
Is the output rating suitable for my home?
A central heating output rating of 37.6 kW makes the ecoTEC Plus 637 most suitable for larger homes with around 20 radiators and a higher demand for heating and hot water.
Are any other options available in the ecoTEC Plus range?
If the 637 is too powerful for your home then there are several models with lower output ratings also available. These include 12 kW, 15 kW, 18 kW, 24 kW and 30 kW system boilers.
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.
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.
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 approved thanks to ultra-quiet operation. 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.
How big is the ecoTEC Plus 637?
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.

Awful boiler. Have had nothing but trouble with it since we had it fitted. Cant even manage to heat one floor at a time during a cold spell - It's had more breakdowns than an Oscar ceremony, am looking to replace after only 5 and a half years - we've kept it serviced had the system flushed regularly but that's made no difference, should've gone for a Worcester Bosch - I advise you to do the same.
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!
