Product Description

Is the output rating suitable for my home?

Combi boilers have two separate output ratings: central heating (CH) output and domestic hot water (DHW) output. The ecoTEC Pro 28 has a CH output of 25.9 kW and DHW output of 27.2 kW making it a great option for properties with up to 10 radiators and a single bathroom.

Is a combi boiler suitable for my home?

Combi boilers heat water directly from the mains supply and deliver it straight to the hot water outlet rather than storing it in a cylinder. Thanks to their cost-effective and space-saving qualities it’s no surprise that combi boilers are now the most popular heating system in the UK.

How long is the warranty period?

All Vaillant ecoTEC Pro boilers have a 2 year warranty as standard but you have the option to extend this to 7 years when the boiler is registered through Vaillant Advance.

What are the key features of the ecoTEC Pro 28?

Some features of the ecoTEC Pro 28 include a low NOx burner, frost protection to help keep the boiler performing well all year round, Vaillant’s aquaCOMFORT warm start feature and ultra-quiet operation.
