Best Quiet Heat Pumps – Buyer’s Guide

Silence is golden, but when it comes to heat pumps, it’s a rare commodity. It’s hard to escape the clanking and buzzing noises that most heat pumps make. But what if we told you there’s a heat pump that not only keeps your home comfortable but also lets you enjoy the sound of silence? That’s right, the Quiet Heat Pump is the answer to all your noise-related problems. It’s so quiet that you can hear a pin drop, or maybe even a whisper, in your home while it’s in operation. So why settle for a noisy heat pump when you can have a quiet one?

If you are planning to purchase or upgrade a heat pump, there are a few things to keep in mind. First of all, you should familiarize yourself with the features and operating capacity of the pump to make sure it’s right for you. And if you want to save money and energy, choose a silent heat pump that will run all year round without disturbing you or your family. So be sure to take all of this information into consideration when looking for the perfect brand and model for your needs.

What are Heat Pumps and How do They Work?

Heat pumps are highly efficient devices that provide heating and cooling to residential and commercial buildings. They work by transferring heat energy from one place to another, rather than by generating heat like traditional furnaces or air conditioners (get more info at

The basic principle of a heat pump is that it extracts heat from the air, ground, or water outside a building, and then pumps that heat into the building to provide warmth. In the summer, the process is reversed, with the heat pump removing warm air from inside the building and transferring it outside to provide cooling.

To achieve this heat transfer, a heat pump consists of several key components. These include an evaporator, a compressor, a condenser, and an expansion valve. The evaporator absorbs heat from the outside air or other heat source and transfers it to a refrigerant fluid. The compressor then compresses the refrigerant, increasing its temperature and pressure. This high-pressure gas is then condensed by the condenser, releasing the heat into the building’s heating system. Finally, the expansion valve allows the refrigerant to expand, reducing its temperature and pressure, before the process repeats.

Types of Heat Pumps

Here are the types of heat pumps that you should look out for study closely.

1. Reversible Heat Pumps Reversible Heat Pumps Reversible heat pumps can deliver heating or air conditioning (cooling) to an interior area in either direction. To invert the coolant flow from the compressor via the condenser and evaporation coils, they use a reversing valve respectively.
2. Solid State/ Ground Heat Pumps Ground Heat Pumps The outside air isn’t the only source of heat we may utilize to keep our homes warm. Solar energy deposited in the ground or in water may be used to power ground source heat pumps, which also need the installation of heat pipes into the ground. Geothermal heat pumps, also known as ground-source heat pumps, offer better efficiency than air-source heat pumps because ground temperatures are more consistent.
3. Air To Air Heat Pumps Air To Air Heat Pumps An air-source heat pump can offer heating for your house or business if you reside in a mild or stable environment. The heat pump unit is usually mounted on the building’s side, sucking air in from the outside and transferring heat through compression and two coils constructed of electrical copper tubing.
4. Underwater/Underground Heat Pumps Underwater/Underground Heat Pumps Instead of using air to disperse heat, water source or underwater heat pumps use water. They aren’t as popular because they require access to a well, lake, or other water supply.
5. Hybrid Heat Pumps Hybrid Heat Pumps A hybrid array consists of a heat pump and another energy source, including a gas boiler, that works together to produce a more consistent source of heat at greater efficiency. It has the benefit of not requiring people who already have a heat source, such as a gas or oil boiler, to alter their radiator if they install it.
6. Cold Сlimate Heat Pumps Cold Сlimate Heat Pumps Cold-climate heat pumps (CCHPs) are the most recent advancement in air-source heat pump technology. CCHPs are so efficient that they can meet up to 90% of space heating demands and have a seasonal efficiency of 250 percent. A CCHP, like other heat pumps, may also be used as a cooling system in the summer.

Best Quiet Heat Pumps: FAQ

Is a heat pump quieter than a furnace?

Furnaces are much quieter than heat pumps, which are usually maintained outside. Heat pumps frequently have compressors that have been incorrectly fitted, leaking ducts, or incorrect refrigerant levels. However, ductless heat pumps are the quietest option when it comes to compressor-bearing equipment like heat pumps and air conditioners.

What is the quietest decibel level for a heat pump?

The quietest decibel level for a heat pump is around 55 dB. This is roughly the equivalent of a quiet conversation or the sound of a refrigerator running. However, some models may operate at even lower decibel levels, particularly those with advanced noise-reducing features.

Are new heat pumps quieter?

Heat pumps that are newer are simply quieter. If you’re wondering about how some of the main manufacturers compare in terms of noise levels, check out some of our articles here in Silence Wiki. Likewise, we have a collection of products we listed above that will choose new quieter heat pumps.

How can I measure the noise level of a heat pump?

You can measure the noise level of a heat pump using a decibel meter. This device measures the intensity of sound in decibels, allowing you to accurately assess the noise level of the heat pump. Many heat pump manufacturers provide decibel ratings for their products, which can also be helpful in determining the noise level of a particular model.

How can I reduce the noise from my neighbour’s heat pump?

Installing a sound blanket to fencing or another frame effectively muffles noise, lowering its unpleasant effects for both home occupants and neighbors. Set up a noise-canceling fence: a plain wooden fence, or even bushes, will deflect noise and conceal your heat pump from your neighbors.

Can I install a quiet heat pump myself, or do I need to hire a professional?

Installing a quiet heat pump can be a complex process, and it is generally recommended that you hire a professional HVAC technician for installation. A professional can ensure that the system is installed correctly and safely, and can also provide guidance on selecting the best system for your needs.

How to Choose Quiet Heat Pumps

Can’t you find a quiet heat pump or the decibel level isn’t posted on the manufacturer’s website? Simply check for the following features on heat pumps that allow for smoother and quieter operation.

1. Average Running Decibels Not all heat pumps make a lot of noise. Decibels are used to measure how loud something is (dB). Experts say 30 decibels is considered quite quiet. The sound level of most heat pumps is around 50 decibels, which is about the same as a refrigerator or a typical car passing by. However, some heat pumps may operate at as low as 35 decibels.
2. Output Capacity This value indicates how many BTUs the heat pump can generate or how large of a room it can efficiently and effectively heat up.
3. Physical Unit Size The precise dimensions of the specified unit are provided in the manufacturer’s manual. Always check for the unit that fits into your desired location.
4. Efficiency Ratings The EECA awards energy stars to heat pumps (Energy Efficiency and Conservation Authority official website). This allows you to choose more energy-efficient heat pumps, allowing you to plan ahead and save money on power.
At initially, a higher Energy Star rating might be more expensive because products with it are likely to be more expensive. However, because it saves energy, it will pay for itself over time while providing the best heating and cooling for your house.
5. Power There are a lot of power options when buying a heat pump. But to get you started, a basic rule of thumb (just suggestive) is 0.12kW/square meter of space, so a 50m2 lounge could need a 6kW heat pump.
6. Unit Price Many online businesses sell heat pumps without the cost of installation. Service or repair shops, on the other hand, combine them for an estimate of $2,500-$4,500. Always look for the one that will accommodate all your needs with the same price range.
7. Care and Maintenance If you use heat pumps frequently, you should clean or service them every 6-8 months to ensure that they operate at their optimum. If you don’t use yours very often, you can go longer between cleanings.
