The AMBIHEAT HDc-270 Heat Pump is a smart, energy efficient alternative for areas where a traditional solar water heater may not be suitable. It uses the heat from the surrounding air and does not rely on the direct sunlight, to heat your water and provides a reliable, efficient and sustainable way to reduce your water heating energy consumption. A Heat Pump works day and night as it extracts heat from the surrounding air and doesn’t rely on direct sunlight to operate.
