NeoTherm is a direct vent, sealed combustion, condensing boiler boasting 95% efficiency that modulates with a 5 to 1 turndown. Zero clearance to combustibles and the convenient top connections (horizontal or vertical direct vent) make NeoTherm perfect for tight installations. Featuring an ASME stainless steel heat exchanger and NOx emissions lower than 10ppm, NeoTherm is easy to use and easy on the environment. Built standard with the new LAARS Integrated Control System, all controls are contained in one safe, simple, user-friendly device.
