HEAT PUMP
Heat pump water heaters use electricity to take out the surrounding air and flow it through the pump, causing the temperature to increase, and is then circulated into the water tank ready to be used for hot water heating.
In essence, a heat pump water heater works just like an air conditioner, but in reverse. Instead of pulling the hot air from the inside and dumping it outside, a heat pump water heater draws in ambient air from the outside and warms it up inside.
A heat pump water heater is more efficient than an electric water heater because it does not use electricity to generate heat — which an electric water heater does. Instead, it absorbs heat from the outside and then uses electricity to circulate that heat, ultimately transferring that heat into the water.
Integrated heat pump water heater
Integrated units are paired with a smaller compressor, so they are more compact. In an integrated system the heat pump is often mounted on top of the storage cylinder, including a Evaporator, fan, compressor & condenser.
Split heat pump water heater
The larger the compressor, the more quickly the heat pump system can generate hot water. In split systems, the evaporator, fan and compressors are in a separate unit and connected to the storage cylinder by refrigerant piping, the heated refrigerant gas passes through a heat exchanger located inside the cylinder to heat the water. They’re quite like a split system air conditioner.
