Alarko Aldens W Series Condensing Boiler

Ideal gas-air blend with premix system, high efficiency, low noise level, low flue gas temperature and low emission rate, environmentally friendly product.
Minimum stop-and-go, maximum fuel economy (20-100%) with very wide heating modulation range. Seasonal space heating efficiency within a range of 91-93%.

Thanks to the “cascade system” created by operating multiple boilers in harmony instead of using a single large boiler in a high-capacity central heating system such as building blocks and sites, it achieves up to 16 co-aged cascade possibilities, lowest system modulation rate and the highest possible efficiency.
Even if one or more than one boiler fail, uninterrupted service is ensured with other operating boilers.

Controller panel with knobs and white illuminated large display on Aldens W boilers (leader boiler) will support you.
