Rheem® AmbiPower MDc-180 Heat Pump Water Heater

Description

The Rheem® AmbiPower® MDc-180 is an innovative, energy-efficient heat pump water heater designed to bring affordable, sustainable hot water heating to New Zealand homes. Rather than relying on traditional electricity or gas, the AmbiPower® MDc-180 draws heat from the surrounding air and transfers it into your water supply — no direct sunlight required. Using advanced wrap-around microchannel heating technology, it delivers efficient and reliable hot water day and night, all year round.

Save almost 70% on your water heating energy costs compared to a standard electric water heater,* making the AmbiPower® MDc-180 an ideal upgrade for small to medium households seeking a cost-effective and eco-friendly hot water solution.

Exceptional Energy Efficiency

With a Coefficient of Performance (COP) of up to 4.9, the AmbiPower® MDc-180 is a highly efficient heat pump water heater. The majority of its parts are made from recyclable metals, and its large anode helps enhance the long-term life of the unit.

Works Day and Night, All Year Round

Unlike solar water heaters, the AmbiPower® MDc-180 does not rely on direct sunlight — it draws heat from the surrounding air. With an operating range of -7°C to +43°C, it provides reliable hot water even in cold and frost-prone climates. A 2.4kW backup element ensures hot water availability in even the most extreme conditions.

Built for New Zealand’s Conditions

The AmbiPower® MDc-180 features an enamel-lined water tank to resist corrosion, a side fan design for maximum airflow, and a durable painted sheet metal outer shell — all engineered to withstand New Zealand’s varied weather conditions.
