Used MARUSHO DENKI DWF-111112 #9314299 for sale

MARUSHO DENKI DWF-111112 is a high-efficiency, two-stage direct-fired gas furnace designed for a wide range of heating applications. This efficient furnace features a high-efficiency pre-mixed burner, high-temperature heat exchanger, and a robust blower motor. It can be used with natural gas or propane and is certified up to 88% AFUE. The burner is designed to operate at low operating pressures, allowing for optimal efficiency, while still providing a burn rate that is greater than a standard gas furnace. This allows for a more efficient transfer of energy to the exchanger and resulting high efficiency levels. The heat exchanger is fabricated from a stainless-steel inner tube and is designed to eliminate corrosion, while allowing for efficient heat transfer. The combustion chamber, which encompasses the heat exchanger, is also composed of stainless steel to prevent rusting and ensure reliability. The robust blower motor is precisely matched to the burner to provide stable airflow through the equipment, and an electronically commutated motor (ECM) is included for increased efficiency and quieter operation. The included ECM also modulates the cooling speed and allows for precise control of the system. DWF-111112 also offers a two-stage gas valve, allowing for a lower temperature setting when it's not needed, and activating higher temperatures to provide optimum comfort. MARUSHO DENKI DWF-111112 features an integrated humidifier which can be connected to an optional pre-wired humidifier control. This allows the furnace to provide and maintain proper indoor humidity levels, reducing energy costs. The appliance also has diagnostic indicators and a self-diagnostic unit to notify the user of any faults or issues that may arise. Overall, DWF-111112 is a powerful and efficient direct-fired gas furnace that excels in energy efficiency, comfort, and reliability. Its two-stage gas valve provides precise control over machine settings, while its robust blower motor and two-stage burner ensure quiet operation and optimal efficiency levels. The integrated humidifier provides an extra level of comfort to users, and the tool is certified up to 88% AFUE.
