How Do Heat Pump Hot Water Systems Work?

Homeowners today can choose from a variety of home water heating systems. This article will explore heat pump hot water systems, how they work, and the benefits and downsides of choosing this option.

What is a Heat Pump Hot Water System

Heat pump hot water systems are household appliances used to heat water by absorbing warmth from the atmosphere and transferring it to the water. They use solar energy to heat the water, reducing the energy used compared to traditional heating systems since solar energy is renewable.

How Heat Pump Systems Work

Heat pump hot water systems work in a similar way to refrigerators. Using a heat exchange system, they transfer heat from the external environment to the pump's water. The temperature of the extracted heat is then raised with an electric compressor and pumped into the water. Heat pump hot water systems can heat water in low temperatures as long as the heat exchanger is not frozen.

While heat pumps can generate heat even when the temperature is as low as -10º C, it is best to install them annually in areas with temperatures between 4.4º-32.2ºC. The site should also allow for up to 1000 cubic feet (ca. 28 m³) around the heat pump system. You’ll need a licensed plumber to help install your new hot water system for optimal system performance.

Pros of a Heat Pump Hot Water System

Heat pumps are trendy for their many advantages over conventional water heating systems. These benefits make them a considerable choice over other types of heat pumps and are listed below.

Saves Energy

They use only about 70% of the energy a traditional electric water heater would. Also, as they use the heat around the unit, they are best installed in areas with excess heat, such as furnace rooms. Doing this allows them to function well and also serves as a way to maximise energy.

Cost Effective

With electricity saved when using heat pump hot water systems, a homeowner can expect to pay $300 less on electricity bills each year. Also, as opposed to traditional heaters, which last about 8-12 years, heat pump systems can last up to 15 years with proper maintenance.

Cons of a Heat Pump Hot Water System

Some of the advantages of this system could potentially become disadvantageous to the system when proper thought is not given before installation. Some of these downsides include:

Cooling Ability

As mentioned earlier, heat pumps are best installed in places with excess heat as they cool the rooms they are installed in. As a result, they might make your rooms much cooler in cold seasons when installed close to the living area.

Cost of Installation

While heat pump hot water systems help save electricity bills, they are expensive to install initially.

Conclusion

Hot water systems are a household essential, and therefore, people put much thought into installing a system in their homes. Heat pumps are just one of the many options available to choose from, and we simply provide you with the information needed on heat pumps to make an informed decision.
