Fast and Consistent Hot Water

The ecoTEC Pro 30 uses Vaillant’s aquaCOMFORT warm-start system to help provide hot water more quickly and maintain a consistent outlet temperature.

With a domestic hot water flow rate of up to 12.3 litres per minute, it offers reliable performance for showers, baths and everyday household use without requiring a separate hot water cylinder.

Why Choose the 15mm Scale Reducer?

The included 15mm Scale Reducer is designed to help reduce limescale deposits within the domestic hot water system. This can be particularly useful in hard-water areas, where mineral build-up may gradually affect performance.

Benefits include:

• Helps minimise limescale formation
• Supports consistent hot water performance
• Helps protect internal boiler components
• May reduce future maintenance requirements
• Supports long-term system efficiency
• Particularly suitable for installations in hard-water areas

Efficient Heating Performance

The ecoTEC Pro 30 automatically adjusts its output according to the heating demand of the property. Its modulation technology helps prevent unnecessary energy use while maintaining a comfortable and stable indoor temperature.

The boiler offers a nominal heating output range of approximately 6.9kW to 25.7kW in condensing mode, allowing it to operate efficiently during periods of lower heating demand.

Durable Stainless Steel Heat Exchangers

The ecoTEC Pro range uses premium-quality stainless steel heat exchangers designed to provide efficient heat transfer, durability and dependable long-term performance.

The boiler also features a brass diverter valve and a front-access internal layout, helping make servicing and component replacement more straightforward for heating engineers.

Quiet and Easy to Use

Designed for everyday convenience, the ecoTEC Pro 30 features a clear illuminated display and straightforward controls. Its Quiet Mark accreditation also makes it a suitable option for homes where low operating noise is important.

Complete Installation Package

Including the boiler, horizontal flue and 15mm scale reducer within one package helps simplify product selection and ensures the main installation components are supplied together.

The horizontal flue safely directs combustion gases through an external wall, while the scale reducer adds an extra level of protection for the domestic hot water circuit.

Warranty and Peace of Mind

The ecoTEC Pro range is supplied with a 2-year manufacturer guarantee as standard. A longer guarantee may be available when the boiler is installed and registered by an eligible Vaillant Advance installer, subject to Vaillant’s current terms and installation requirements.
