The Glow-worm Energy 30kW combi boiler offers a highly adaptable and efficient heating solution tailored for a broad spectrum of residential applications. Delivering an excellent flow rate of 12.2 litres per minute, this compact unit consistently meets the hot water expectations of modern properties. Central to its design is an automotive-grade aluminium heat exchanger featuring large waterways, which significantly reduces the risk of blockages. This makes the system exceptionally well-suited for retrofit installations on older heating circuits where suspended debris might otherwise compromise system integrity.

Heating engineers benefit from a lightweight construction weighing only 32.3kg, combined with flexible top and rear flue options that adapt easily to challenging installation environments. The integration of a high-efficiency ErP modulating Grundfos pump dynamically adjusts performance to match real-time heating demands, substantially lowering operational running costs for the end user. Boasting a bright, easily readable digital interface and compatibility with a comprehensive range of intelligent controls, this wall-mounted boiler combines aesthetic appeal with robust, dependable engineering.
