HEX3 is the proprietary heat exchanger at the core of our combustion technology. It is utilised across our entire premium gas boiler range. Featuring a multi-pipe construction, the heat exchanger helps achieve a high condensation rate even at full load, returning the highest levels of efficiency. The HEX3 configuration also results in significantly lower NOx emissions, with ELCO’s products performing 60% below the EU NOx limit on average.

Ease of installation and transportation are equally important, especially as most products are either retrofitted or installed as replacement systems in existing buildings. As a result, modularity, cascading and low weight are also crucial. Thanks to a compact, modular design, ELCO products can be used in a wide variety of projects and easily transported through a building’s infrastructure.
