An environmentally friendly hot water system to save you money

Huge energy savings of up to 80%

A Heat Pump is an energy-efficient way to reduce your energy requirements to heat hot water by 50-80%.
They don’t require solar panels, and work day and night, rain, hail, or sunshine!

How a Heat Pump saves you money

Heat Pumps work a bit like a reverse refrigerator – transferring heat from the air, through a heat exchange system to heat your water; this is why they are often referred to as ‘air-source Heat Pumps’.

By concentrating this existing heat, instead of creating more, Heat Pumps can significantly reduce your household’s greenhouse gas emissions and energy consumption – saving you money.

Unlike solar, they don’t require the sun to work, and although they use electricity to operate, they are roughly four times more efficient than a conventional electric water heater.

How does the Heat Pump work?

1. Heat Pumps draw air in through a fan to an evaporator where the heat in the air is absorbed by a refrigerant.
2. The warm air turns the refrigerant from liquid to gas.
3. The gas refrigerant is compressed, causing the pressure and temperature to increase.
4. This hot vapour flows through a heat exchanger to heat the water and cool the refrigerant.
5. The liquid refrigerant then flows into an expansion valve to reduce its pressure, allowing it to cool and enter the evaporator to repeat the cycle.

As a result of this process Heat Pump hot water systems require much less electricity to heat water than conventional electric hot water systems.
An Emerald Heat Pump hot water system has a high COP (Coefficient of Performance) for high energy savings – about 74-80% less energy when compared to traditional electric hot water where 1 kW of electricity generates 1 kW of thermal output.
