Manufacturing in the USA since 1948, Laars Heating Systems builds high-efficiency residential and commercial boilers, volume water heaters, and pool heaters at its Rochester, New Hampshire headquarters.

Contractors, engineers, and builders choose Laars for durable, USA-made equipment backed by strong training and support resources.
24hr Supply carries the Laars models specifiers ask for by name. On the commercial side, condensing units like the NeoTherm, MagnaTherm, and modular Pennant deliver efficiencies up to 96% with advanced Laars Linc controls, while the Mighty Therm2 keeps replacement jobs simple. For residential work, the Mascot FT and Combi-Heat combine space heating and domestic hot water, and the LT Series condensing tankless water heater handles high-temp output. Companion controls, tanks, and accessories complete each installation.
