Mitsubishi ERSF-NM6E & WUZ-SA36NMZ 36,000 BTU Ecodan Air to Water Heat Pump w/ Hydrobox

Mitsubishi ERSF-NM6E & WUZ-SA36NMZ 36,000 BTU Ecodan Air-to-Water Heat Pump with Hydrobox

The Mitsubishi ERSF-NM6E Hydrobox paired with the WUZ-SA36NMZ 36,000 BTU Ecodan Air-to-Water Heat Pump delivers high-efficiency hydronic heating and domestic hot water using advanced heat pump technology. As part of Mitsubishi’s Ecodan® air-to-water system , this solution captures heat from outdoor air and transfers it to water, providing an energy-efficient way to power radiant floor heating, fan coils, and hot water systems.

The ERSF-NM6E Hydrobox indoor unit acts as the system’s hydraulic and control center, managing water flow, system performance, and temperature control. Combined with the WUZ-SA36NMZ outdoor unit , the system provides 36,000 BTU of heating capacity with advanced inverter-driven technology that adjusts output based on demand for improved efficiency and consistent comfort.

Designed for quiet operation and reliable performance, Mitsubishi Ecodan heat pump systems offer an environmentally friendly alternative to traditional boilers or fossil fuel heating systems. With intelligent controls and high-performance components, this system is ideal for residential hydronic heating applications seeking energy efficiency, comfort, and long-term reliability.
