Hot water heat pumps work by using a refrigeration cycle to extract heat from the air and transfer it to water. This process involves a refrigerant that passes through an evaporator, compressor, and condenser to heat the water efficiently
The benefits include significant energy savings (up to 70% less electricity), reduced greenhouse gas emissions, and longer system lifespan compared to traditional water heaters
Yes, they can be used in cold climates, though they may require additional components like electric booster elements or defrost cycles to maintain efficiency
Many governments offer rebates and incentives to encourage the adoption of energy-efficient technologies like heat pumps. For example, Australia provides rebates for hot water heat pump installations
