The NeoTherm® LC condensing boiler is a fully packaged, 1 million- or 1.7 million-Btu, space-saving hydronic unit that offers 94 percent thermal efficiency. It is a direct vent, sealed-combustion boiler or volume water heater that modulates with a 10-to-1 turndown. 

The condensate neutralizer accessory provides installers with an effective way to eliminate acidity from the condensation that is drained from a condensing boiler or condensing tankless unit.
