Designed for Traditional Heating Systems

The ecoTEC Plus 430 is specifically engineered for homes with an open-vented heating system, operating in conjunction with a separate hot water cylinder and cold water storage tank.

Unlike a combi boiler, it is dedicated to central heating, making it ideal for larger homes that benefit from stored hot water and require higher heating output.

With a 30kW central heating output, the ecoTEC Plus 430 is well suited to larger properties or homes with greater radiator demand.

Its intelligent modulation technology automatically adjusts the boiler's output according to the heating requirements of the property, helping reduce gas consumption while maintaining a comfortable indoor temperature.

The boiler delivers a heating output range of approximately 7.5kW to 31.8kW in condensing mode, providing efficient performance across varying heating loads.

Compact Installation

Despite its powerful output, the ecoTEC Plus 430 maintains compact dimensions that make installation straightforward in kitchens, utility rooms, and airing cupboards.

Dimensions

• Height: 600mm
• Width: 375mm
• Depth: 320mm

Its compact footprint provides excellent installation flexibility while allowing easy access for servicing and maintenance.
