The NeoTherm® condensing boiler is a fully packaged, space-saving hydronic unit that offers 95 percent energy efficiency. The family’s new residential models are 80-, 105-, 150-, and 210-MBtuh sizes. The direct-vent, sealed combustion boiler modulates with a 5 to 1 turndown. According to the manufacturer, zero clearance to combustibles and convenient top connection (horizontal or vertical direct vent) features make it a good choice for tight installations. The natural gas- or LP-fired boiler features an American Society of Mechanical Engineers stainless steel heat exchanger, integral three-speed boiler pump, and low NOx emissions. Features include top-mounted water and gas lines and air intake, permitting close, multiple boiler installation.
