What is a heat pump hot water system?
A heat pump absorbs the heat from the surrounding air and use it to heat your water. Therefore, these systems are also referred to as ‘air-source heat pumps’. These systems are more efficient than conventional water heaters despite using electricity They can save money and energy while reducing greenhouse gas emissions.
How do heat pump hot water systems work?
A heat pump system works much like a refrigerator in reverse – by transferring the heat outside the unit to the water inside the heater. It does this using a heat exchange system.
- Outside air is pulled into the heat pump with a fan into the evaporator which contains a special refrigerant stored in the piping.
- The warm air turns the refrigerant from liquid to gas.
- A compressor pumps the refrigerant gas through a value which compresses it. The result of this process is heat generation.
- A heat exchanger moves the heat from the gas pipes to a water storage tank.
