Neotherm LC

The NeoTherm LC is a direct vent, sealed combustion, condensing and modulating hydronic boiler. These compact 1.0 million and 1.2 million BTU/h workhorses are powered by a dual fired ASME stainless steel water tube heat exchanger resulting in 10:1 turndown and thermal efficiencies as high as 99%. Setup, operation and diagnostics are made easy with the NeoTherm LC’s large color touch screen display. The advanced NeoTherm LC control system includes a cascading feature that allows for up to four boilers to be lead lagged with onboard controls. Up to eight NeoTherm LC boilers can be lead lagged when coupled with M4 and M4EXT controllers. This results in a modulating heating cell of up to 9.6 million BTU/hr with a combined 80:1 turndown.
