Laars NTH105NXN3 NeoTherm® 105 Input MBtu 95% AFUE Condensing Hot Water Gas Boiler - Direct Vent

Laars NeoTherm boilers set a new standard for high efficiency hydronic heating in a small, compact package. A fully stainless steel heat exchanger lies at the heart of the boiler, ensuring that heat transfer between burned fuel and your home's heating medium is effortless and fast. This condensing boiler extracts every last BTU possible of heat energy from burned fuel, keeping your home's heating bills to an absolute minimum. Sealed combustion burning chambers and venting systems keep your home's air fresh while allowing the boiler to supply itself with oxygen saturated combustion air. A fully modulating burner allows the boiler to scale its burning rate to your home's heating demand, topping off the feature set of this highly efficient boiler.

• Stainless Steel Heat Exchanger - The NTH105NXN3's heat exchanger is constructed from high grade stainless steel. This high grade material not only facilitates greater heat transfer between combusted flue gas and the system's hot water, but also provides a significant durability increase.
• Fully Modulating Burner - The NeoTherm's is capable of a 5 to 1 turndown ratio, firing at between 20% and 100% of its total capacity to efficiently match your home's heating needs. This results in less temperature fluctuation and lower heating bills during warmer months.
• Separated Combustion Venting - The NeoTherm's venting system separates your home's air from the air used by the burner for combustion, keeping your home's air oxygenated and fresh and the burner's flame well supplied at the same time.
• Included Pump - This NeoTherm comes with a Laars pump pre-installed, eliminating the need to purchase a system circulation pump.
