According to the US Department of Energy, water heating accounts for 18% of a household's energy use and it is typically the second largest energy expense in any home. Therefore, there is a growing demand for energy-efficient & eco-friendly water heating solutions in homes & business places, and heat pump water heaters (HPWHs) is the answer. Aside from being used to heat and cool indoor air, heat pumps are gaining popularity as sustainable water heaters.
Making use of a heat pump for heating water can reduce your energy consumption, lower your utility bill, and eradicate your greenhouse gas emissions. A recent publication by Natural Resources Canada stated that a heat pump water heater is about four times more efficient than other traditional water heating systems (like the electrical water heater) and that it makes use of 70% less energy. This growing demand has led to an increase in the number of heat pump water heater manufacturers.
