The Sanden SANCO2 heat pump water heater is an energy-efficient alternative to traditional electric or gas water heaters. The SANCO2 absorbs heat from the outside air to heat water – saving energy, money and reducing greenhouse gas emissions. It’s four times more efficient than traditional electric water heaters, allows use of off-peak power and has a whisper-quiet noise level (38dB), the company explains. The Slimline heat pump is designed for a reduced footprint, while the two tank sizes fit any hot water needs and feature a corrosion-resistant stainless-steel design.
