When you have had a stressful day, sometimes all you want is some peace. A noisy heat pump is the last thing you want when you are trying to calm your nerves and relax. This is why you should consider buying a heat pump with low noise levels for your home.
How will you know which brand and model runs quietly? Leave that to us. In this article, we will review some of the quietest heat pumps to help you make a suitable selection. We have tested and reviewed several heat pumps from different brands to find those that operate quietly.
Are heat pumps noisy?
Noise level is measured in decibels. Some heat pumps have a sound rating of up to 80 dB which is quite noisy. Other models however have a sound level rating as low as 30 dB which is equivalent to a whisper.
Heat pump noise is caused by compressors and fans. You can hear rattling or vibrating noises as your heat pump heats or cools your home. The goal is to select a quiet heat pump to ensure your comfort.
How and where your heat pump is installed will determine its noise levels. Be sure to consult a professional before deciding where to install your heat pump. Consider hiring an expert HVAC technician to properly install your heat pump.
Types of heat pumps
Before selecting a heat pump, try to research the types available. The type of heat pump determines its noise levels. Here are the most common types of heat pumps.
Air-source heat pumps
Air-source heat pumps use air to heat or cool your home. These heat pumps work by absorbing heat from the air and transferring it to the refrigerant. This refrigerant then passes through a compressor and heats your indoor space through radiators.
You can choose a ducted or ductless mini-split air-source heat pump. Ducted heat pumps require ductwork to function while ductless heat pumps don’t require ductwork. Ductless heat pumps are more energy-efficient than ducted systems. Ducted systems lose between 25% to 40% of energy through ducts.
Air-source heat pumps can be quite noisy since they are often located outside your home. The noise level of an air-source heat pump depends on its brand, installation, and how hard it is working. Most air-source heat pumps produce noise ranging from around 40 to 60 dBs.
Ground-source heat pumps
Ground-source heat pumps utilize heat from the earth to heat or cool your home. Since they use renewable energy, these heat pumps are energy-efficient. A ground-source heat pump can help you cut down utility costs in the long run.
Ground source heat pumps are also eco-friendly since they utilize renewable energy from soil or water in the ground. Ground-source heat pumps are some of the quietest heat pumps that you can choose for your home.
These types of heat pumps are generally quieter than other types like air-source heat pumps. Ground-source heat pumps produce an average sound level rate of 42 dBs. Since ground-source heat pumps don’t draw heat from the air, they don’t require fans and are therefore quieter than air-source heat pumps.
Geothermal heat pumps
Geothermal heat pumps use renewable geothermal energy from the earth’s core to heat or cool your indoor space. Like ground-source heat pumps, geothermal heat pumps are very energy-efficient and eco-friendly.
A geothermal heat pump saves you about 30% to 60% of your heating costs and around 50% of your cooling costs. Geothermal heat pumps are some of the least noisy heat pumps available in the market. These heat pumps run quietly because they don’t require outdoor compressors or fans to operate.
