What Is A Heat Pump Hot Water System?

As the name implies, a heat pump water system is an electrical device that extracts heat from one place and transfers it to another, generally from its surroundings, to heat water rather than using an electric element to heat the water. It is said to be more energy-efficient than other hot water systems.

What To Consider When Purchasing A Heat Pump Water Heater System

Basically, a heat pump water heater is an air conditioner in reverse, compressing gas to produce heat instead of cold. Inside the water heater, a coil of pipe carries hot gas. Heat is then transferred from the copper pipes into the water through it. The heat pump heating system is a great option and system for your homes that generate their own power or runs off of batteries. If you plan to buy a hot water heat pump heater, here are a few things to consider:

  • Capacity – How many people does my water heater pump need to provide hot water for?

  • Solar-Assisted Heat Pump – Do I have solar thermal panels on my roof if I wish to have this type of hot water system?

  • Outside space – Heat pumps work best outside. Do you have a location outside where the heat pump will fit?

  • Noise – Heat pumps are noisier than electric or gas units except if you purchase those low-noise models. Our hot water specialists advise ensuring it isn’t next to your window or a neighbour’s window.

Pros and Cons of Heat Pump Hot Water Systems

Heat pumps hot water heaters use far less renewable energy than traditional electric water heaters and work beautifully in conjunction with a household solar system.


The upfront cost of hot water heat pump almost costs twice that of the traditional electric hot water system. However, it uses about 66% less electricity than the traditional electric storage hot water system so operating running costs are significantly lower.


The compressor makes considerable noise so it must be placed outside your home where it won’t disturb you or your neighbors. You will also need space for it to have enough airflow.

Environmental Impact

The heat pump water heater system works harder during winter months because the surrounding air does not have enough heat to work with. Since there is less electricity used, the emission of greenhouse gases is also reduced.

When Should I Have Heat Pump Water Heater Repairs?

Here are some common problems when it comes to heat pump water heaters systems:

No Hot Water

Before anything else, check if there is no trip in the power box where your heat pump is connected. If there is nothing wrong, the next thing to do is to inspect if the thermostat’s setting is set too low.

Rumbling Noise

There is usually a humming sound coming from your heat pump hot water system. However, if you hear unusual sounds similar to that of mini fireworks inside your hot water heater tank, this is caused by sediment build-up. It is important to flush your hot water twice a year.

Rotten Smell In Hot Water

The reaction of tap water coming in contact with the anode rod, most likely one which is made of magnesium, can cause the smell of the hot water coming out from your shower to be putrid. The smell may even come close to a rotten egg. Replace it with an aluminum anode rod.
