What Is a Heat Pump Hot Water Heater?

Heat pump water heaters use air to heat water, making them very efficient. A compact outdoor heat pump unit extracts ambient heat and transfers it to your home's water tank. This process uses around 60% less electricity compared to conventional electric storage tanks.

Heat is absorbed into refrigerant gases which are compressed and pumped into a heat exchanger connected to the hot water tank. Here, the heat is transferred rapidly raising water temperature. Modern systems are smart, self-contained units controlled by a digital thermostat and sensors.

Advantages of heat pump systems:

Energy efficient - use far less power than traditional electric systems
Eco-friendly - reduce greenhouse emissions
Quiet operation - specially designed fan and compressor
Save on bills - reduced energy use lowers costs
Long lifespan - heat pump units last 10-12 years
Continuous hot water - storage tank holds heated supply ready to use
Rebates available - government incentives may reduce upfront cost

Types of Heat Pump Water Heaters

There are two main types of heat pump hot water systems we install:

Integrated (All-in-One) Heat Pump Units

An integrated heat pump system has the storage tank and heat pump combined in one tall, slimline unit. The tank fits neatly on top enclosing the heat pump components underneath.

Integrated units are compact, convenient all-in-one systems ideal when space is limited. Their self-contained design allows flexible placement.

We supply premium integrated heat pumps from Rheem, Dux, and Stiebel Eltron with a wide range of tank capacities. 

Split System Heat Pumps

Split systems separate the heat pump unit from the hot water storage tank. This allows flexible positioning with the tank indoors and compressor outdoors.

Split systems are preferred when:

  • There are noise concerns - the outdoor heat pump is barely audible
  • More space is needed for larger water tanks up to 400 liters capacity
  • Optimal sun exposure is required for the heat pump to maximise efficiency

We offer split systems from leading brands like Sanden, Quantum and Haier with the ability to pair units to tanks with solar compatibility.

Both integrated and split types utilise the same energy efficient heat extraction technology–the main difference is component separation. Our experts can advise you on the best system for your home.

Heat Pump Hot Water Repairs

While generally reliable, heat pumps can develop minor faults over time. The most common issues we get called to repair include:Water Leaks - Leaks originating from the storage tank, valves, fittings or pipework require plumbing repairs. We find and fix the source of any water leakage.

Refrigerant Leaks - Leaking refrigerant gas will compromise the heat pump's efficiency. We locate and seal refrigerant leaks and safely recharge gas levels.

Burner or Element Failure - If the electric heating elements or booster burner malfunction, the backup system is affected. We replace damaged heating elements and service gas valves/burners.

Pilot Light Outages - Some units rely on a pilot light for ignition. If the flame goes out repeatedly, adjustments or part replacements are needed.

Faulty Sensors - Sensors like air intake, water flow and temperature play a key role. Faulty sensors will be diagnosed and replaced.

Power Supply Issues - Electrical faults like voltage fluctuations, wiring issues or PC board malfunctions can halt operation. We troubleshoot and remedy power issues.

Noisy Operation - Unusual noise from the unit often indicates fan bearings require lubrication or the compressor needs servicing.

For any heat pump repairs needed, our licensed technicians have the knowledge and experience to get your system running efficiently again.
