Heat Pumps

With heat pump hot water systems, you can utilise FREE energy in the air to heat your water!

Heat pumps use cutting edge technology that transfers thermal energy from air directly into water, which provides hot water for you around the clock. The best thing is, it reduces water heating consumption by up to 65% and doesn’t need the sun or fossil fuels to provide a continual energy source!

heat-pump-hot-waterA heat pump is the perfect way for homeowners to reduce their energy consumption, and thus general living costs.

Benefits of a heat pump:

  • Extracts FREE heat energy from the air and uses it to heat water
  • Reduces your power consumption and carbon footprint
  • Is a quick and easy replacement for electric storage water heaters
  • Uses up to 65% less energy than conventional electric water heaters
  • Does not require roof top collectors
  • Eligible for Government Small-scale Technology Certificates

Selecting a Heat Pump System

Heat pumps are the perfect replacement of your old electric water heater, and can save you over $560* per year. In areas where residential gas reticulation isn’t available or solar collectors on the roof aren’t feasible, heat pumps allow a quick and easy changeover from electric water heaters.

There are 2 models produced by Chromagen that suit the majority of residential needs.

Model Suitable (in moderate climate) for: Heat up time Recovery rate Capacity
Chromagen HP170 3-4 persons 5h:43m 30 L/hr 170 Litres
Chromagen HP280 3-6 persons 5h:13m 54 L/hr 280 Litres

Performance of the heat pump is dependent on the ambient temperature of your house’s location, so a house in Queensland will have faster heat up times and recovery rates than a house in Tasmania. (Figures above based on expected recovery times in Brisbane).

In a moderate climate, the HP170 model can service homes with up to 4 people, making it ideal for small to medium houses, apartments and retirement villages. The HP280 model with its increased heating capacity and larger storage is suited to larger homes with higher hot water demands.

Q: Why would I install a heat pump?

A: Heat pumps are recommended for the replacement of old energy-hungry electric water heaters, where residential gas connection is not available or where roof-mounted solar collectors are not feasible.

Q: What is the difference between a heat pump and a solar hot water heater?

A: A heat pump does not use roof-top solar collectors to absorb the sun’s thermal energy. Instead it uses advanced technology to extract heat energy from the surrounding air, and uses this to heat water.

Heat pumps are therefore ideal where it is not practical to install collectors on the roof due to matters of roof space, orientation or construction.

Q: How does a heat pump work?

A: In very basic terms, an air-sourced heat pump is able to extract heat energy from the surrounding air and transfer it to water in the tank.

A heat pump is like an ‘energy multiplier’ in that it can generate around 4kW of output heat, for every 1kW of power input (depending on the surroundings). That is remarkable performance efficiency that can lead to savings of up to 75% over conventional electric storage water heaters.

Q: How much can I save with a heat pump water heater?

A: A heat pump could reduce your annual water heating costs by between 60-75%. This is because the heat pump technology extracts heat energy from the air, thereby reducing your reliance on electrical power. The savings in water heating costs are based on government CER (AS/NZS 4324) modelling.

Q: How much hot water will I get from my heat pump?

A: The Midea heat pumps from Chromagen come in two water holding capacities; 170 litres and 282 litres.

Chromagen recommends allowing 50 litres of hot water per person, per day.

Q: Will my heat pump work on an Off Peak tariff?

A: Yes it will, but this is not recommended by Chromagen. If run with off-peak, it will be generally running in during the evenings where ambient temperatures are cooler than that of the day. While heat pumps can work in any weather or climate, they are most efficient in warm ambient temperatures and high humidity.

The higher the temperature and humidity the more heat energy can be extracted from the air. Therefore if you run your heat pump on an off-peak tariff it may actually cost you more than if you ran it with a day rate tariff.

Q: Is it quiet?

A: Absolutely! The Midea heat pump is one of the quietest heat pumps in Australia, operating at only 48 dBA. That sound level is between the level of a quiet library and a quiet conversation at home.

Therefore, this heat pump is perfect for situations where you need to install your water heater near a boundary fence or a bedroom.

Q: Will my Midea heat pump work in low temperatures?

A: Yes it will. Heat pumps can work in any weather or climate but they are most efficient at warm ambient temperatures and high humidity. The higher the temperature and humidity the more heat energy can be extracted from the air.

The Midea heat pump from Chromagen has 3 running modes to ensure you always get hot water; 1) ECO mode, 2) Hybrid mode and 3) E-heater mode.
ECO mode is the standard mode where the highest efficiency is achieved. The heat pump will run in this mode without the element, in warm ambient temperatures.

Hybrid mode automatically activates when the air temperature drops below 10°C. In this mode both the heat pump and electric element are working together.
When the air temperature drops to below 5°C, the heat pump will automatically run in E-heater mode, where the electric element is used solely to heat the water.
