HEAT PUMP BENEFITS

ENERGY EFFICIENCY

Government agency EECA has identified heat pumps as one of the most energy efficient forms of heating available in New Zealand. This is because heat pumps do not create heat; they simply move available heat from one place to another.

LOWEST RUNNING COSTS

Compared to other common forms of heating, a heat pump is the cheapest heating system to run.

HOW A HEAT PUMP WORKS

Heat pumps do not create heat; they simply move available heat from one place to another. An outdoor unit absorbs warmth from the surrounding air and transfers it into your home. As outside temperatures drop, your heat pump must work harder to transfer the same amount of heat. This makes heat pumps the most efficient form of heating available.

WINTER / HEATING

In heating mode the outdoor units heat exchanger is used to absorb heat energy from the surrounding outdoor air using refrigerant as the heat transfer medium.
The hot refrigerant is pumped through copper pipes to the indoor units heat exchanger and the heat energy is transferred to the cooler indoor room air as the air passes over the indoor heat exchanger warming the room.

SUMMER / COOLING

In cooling mode the indoor units heat exchanger is used to absorb heat energy from the indoor room air using refrigerant as the heat transfer medium cooling the room air.
The refrigerant is then sucked back to the outdoor unit through copper pipes and the heat energy is rejected into the surrounding air outside via the outdoor units heat exchanger.
