Product Description

Designed and manufactured by Vaillant, the ecoTEC Plus 825 is a condensing combi gas boiler that has been endorsed by the Energy Saving Trust.

How efficient is the ecoTEC Plus 825?

Vaillant are well known for manufacturing highly efficient boilers and this unit is no different. It boasts a 94% efficiency and ErP A-rating for heating and hot water, meaning that it has the potential to lower your heating bills.

Is the output rating suitable for my home? The 825 has a central heating output rating of 20.4 kW which is suitable for properties with up to 10 radiators. The domestic hot water output is 25 kW, great for homes with a single bathroom.

Are other output options available in the Vaillant ecoTEC Plus range?

If you have a larger property the ecoTEC Plus range also includes central heating outputs of 25.4 up to 30.9 kW. The DHW output also increases with the other models, reaching right up to 38.7 kW. Your installer will advise on which model is best for your demands.

Is a combi boiler suitable for my home?

Combi boilers are a great option for smaller properties with 1-2 bathrooms (depending on the DHW output rating). They have become a popular choice as the heat water directly from the mains on demand, removing the need for any additional tanks or cylinders - helping to save space.

How long is the warranty period?

Vaillant have attached a standard 5 year warranty to their ecoTEC Plus boilers and this can be extended to 7 years when installed by a Vaillant Advance installer or 10 years when fitted with a Boiler Protection Kit by a Vaillant Advance installer.

What are the key features of the Vaillant ecoTEC Plus 825?

This version has a flow rate of 10.5 litres per minute which is typical for this size of boiler but the more taps you have the higher the flow rate requires your mains pressure will also have an impact.

It's capable of delivering hot water to a tap within just 5 seconds, has a modulation range of 1:6 for increased efficiency and has Quiet Mark accreditation so you can be confident that it won't be too loud during operation.

How big is the ecoTEC Plus 825?

It's a little lighter than most combi boilers and weighs only 35kg and measures 720 x440 x 340mm (HxWxD) so you'll be able to fit it inside a standard kitchen cupboard.
