sxi range 18 30kW product info Condensing System Boilers The sxi range of condensing system boilers offer a superior level of high efficiency performance. The 18kW and 30kW outputs provide excellent heating performance while protecting the environment and saving householders money. The sxi uses a single reliable stainless steel heat exchanger for easier servicing and dependability. These boilers have achieved the highest energy efficiency rating possible being listed as SEDBUK and gained top marks for low emissions with a NOx class 5 rating the best possible. The 30sxi is also suitable for LPG applications without the need for a conversion kit. The fuel saving performance has been combined with an impressive range of features and they look great too! On-board diagnostics provide superior serviceability and Glow-worm's unique 'continua' electronics will allow these boilers to continue where others may fail due to system faults. Fitted as standard are an inbuilt bypass, frost protection and anti-seizure controls.
