The new 150,000 BTU/Hr. unit boasts a 0.98 Uniform Energy Factor, complementing the existing 199,000 BTU/Hr. model, which maintains a 0.96 UEF. Both units in the ENERGY STAR-certified series are built with oval pipe stainless steel heat exchangers, which the manufacturer claims offer a lifespan 350% longer than traditional copper alternatives while improving heat transmission and reducing scale buildup.

Designed for versatility, the series supports both natural gas and propane, with options for indoor or outdoor mounting. The units are also compatible with cascading configurations, allowing for scalability in larger commercial applications. To address user demand for immediate hot water, the recirculation models include a built-in pump with three speed settings, which can be managed through programmable scheduling or manual push-button activation. According to Chuck O'Donnell, director of marketing for Laars, the equipment is engineered to meet strict NOx regulations while providing reliable, uninterrupted delivery for modern infrastructure needs.
