How efficient is the ecoTEC Pro 24?

Vaillant have manufactured their ecoTEC Pro series with efficiency in mind. This is an A-rated boiler with a high efficiency rating of 94%.

Is the output rating suitable for my home?

The ecoTEC Pro has a CH output of 24.8 kW and a DHW output of 23.4 kW making it well suited to homes with up to 10 radiators and 1 bathroom.

Are other output ratings available in the Vaillant ecoTEC Pro range?

The central heating output doesn’t vary too much across this range with central heating outputs of 25.7 kW and 25.9 kW also available. These are also suitable options for homes with up to 10 radiators. More powerful domestic hot water outputs of 27.2 kW and 30 kW are available in the range, with the latter being an option for homes with 2 bathrooms.

Is a combi boiler suitable for my home?

Combi boilers provide heating and hot water on demand, removing the need for any additional tanks or cylinders to be installed as part of the heating system. This makes them cost-effective units capable of meeting low to moderate demands for hot water.

How long is the warranty period?

ecoTEC Pro boilers come with a 2 year warranty as standard with the option for you to extend this to 7 years when registered through Vaillant Advance.

What are the key features of the ecoTEC Pro 24?

This combi boiler comes with a fully modulating low NOx burner and fan and frost protection to help keep the boiler performing well all year round, making it an extremely reliable boiler. It also features Vaillant’s aquaCOMFORT warm start feature and it’s been Quiet Mark approved.

How big is the Vaillant ecoTEC Pro 24?

Vaillant ecoTEC Pro boilers are compact units with dimensions of 720 x 440 x 335mm (HxWxD) giving you greater flexibility when choosing a location for the installation.
