At a time when many countries are focused on meeting their climate change goals, can heat pumps play a role in building a sustainable future?

Heat pumps have been around for decades. Although historically more popular in temperate climates like Europe and Asia, they are slowly starting to pick up steam in colder climates like North America.

Are Heat Pumps Air Conditioners?

Heat pumps compress a refrigerant to increase the pressure on it. Increasing the pressure on a gas increases its temperature. Decreasing the pressure has the opposite effect in that it decreases the temperature. This is the fundamental principle behind how heat pumps, refrigerators and air conditioners work. 

In a heat pump, the refrigerant is compressed using electricity to raise its temperature. The resulting heat is then moved into your home through the refrigerant. This loss of heat cools the refrigerant, starting the process again and gradually heating your home. This process also works in reverse to cool your home.

This is the primary difference between a heat pump and an air conditioner. It both heats and cools your home.  

There are three main types of heat pumps. These are air source heat pumps (ASHP), ground source heat pumps (GSHP) and absorption heat pumps (ASP). 

Air source heat pumps are the most commonly used. They transfer heat from the air to your home. Ground source heat pumps collect heat from the ground or a water source. This is why they are also called water source heat pumps. Absorption heat pumps are a newer type of heat pump. They source heat from sources including natural gas, air or ground-heated water. 

What makes heat pumps important to the future? There are three main reasons.

Energy efficiency

Heat pumps have several advantages. For one, they work more efficiently than traditional furnaces and air conditioners.

Heat Pump Versus A Furnace

Compared to a furnace, a heat pump has a better coefficient of performance (COP). Heat pumps have a COP of between 3 and 4. This means for every watt of electricity used, a heat pump produces 3 to 4 joules of heat. 

Combustion engines like furnaces and even cars have a maximum efficiency of 85 percent since there is some loss wherever energy is converted from one form to another. In comparison, a furnace’s coefficient of performance is less than 1.

Water Heating

Most people are familiar with using heat pumps for space heating and cooling. But they can also be used to heat the water in your home. Heat pump water heaters are more efficient than traditional water heating. 

The US Department of Energy puts the cost of running a heat pump water heater at between 50 to 75 percent less than conventional water heating.

Cost Savings

It is no secret that heat pumps are expensive to buy and install. On average you can expect to pay more for a heat pump than for either an air conditioner or a furnace. What typically drives up the costs is the complicated process of installing a heat pump. 

Installation typically requires added labor, modifications or more material that will significantly increase the final purchase price.

However, most of the costs invested in a heat pump can be recouped by way of savings. Depending on your climate and the type of system used, a heat pump can save you anywhere from 20 to 80 percent on your electricity bill. Get a quote and find out how much you could save if you switched to a heat pump.

Although it is the most expensive system to install, a ground source heat pump is said to produce the most energy savings. Geothermal systems can reduce energy use by between 30 to 60 percent and cut your bill by up to 80 percent at the same time.

Creating Employment

A frequently overlooked fact is how young technologies like heat pumps and even solar panels are. Currently, they represent only a small fraction of global energy production compared to traditional fossil fuel generation. 

The heat pump market has a lot of room for growth. Driven by increasing demand, policy interventions, and growing consumer awareness around sustainability and renewable energy, the market for heat pumps is expected to grow by 8 percent every year. This market growth is important because it will create massive employment opportunities and economic development. According to environmentalists at Greenpeace, installing 900,000 heat pumps in the UK would directly result in the creation of 138,600 jobs and inject $10 billion into the economy.

The Importance Of Heat Pumps

Increased adoption of heat pumps will create more employment which will help boost economies. On a consumer level, switching to heat pumps will help create more energy efficient homes. 

Heat pumps are a more efficient HVAC system because they combine both heating and cooling. Rather than have a furnace for heating and an air conditioner for cooling, you can have one system that performs both functions. 

While a heat pump is more expensive than either of the two, it is much cheaper than the two combined. For homes that require both heating and cooling, it makes more sense financially to get a heat pump than to install air conditioning and a furnace separately. Get an estimate and compare what it would cost to get a heat pump versus the cost of a furnace and air conditioner.

The improved efficiency of a heat pump and the fact that it reduces consumption of natural gas has an important part to play in building a sustainable future.

The Role Of Heat Pumps In A Sustainable Future

Switching to renewable energy sources and electrifying are thought to be the most realistic ways of reducing our carbon footprint and fighting global warming. To that end, countries around the world are adopting cleaner sources of energy like hydrogen, biogas and solar. 

Heat pumps as well can help us transition to a more carbon neutral environment. Heat pumps run off electricity rather than use natural gas like a furnace does

Switching to heat pumps could offset over 8 million tons of carbon emissions by 2050 according to a research report by the Rocky Mountain Institute. Combined with a renewable energy source like solar, having a heat pump in your home would make a huge contribution to a more sustainable future.

The upfront cost of a heat pump also leaves homeowners thinking if it is really worth installing this type of system, and whether or not there other options that are cheaper. In this guide, we will go over each and every advantage and disadvantage of installing a heat pump. So that you can decide if it is worth it to install it in your home.

Heat pump advantages

Requires less maintenance than traditional systems

Heating systems such as gas fireplaces, or furnaces require additional maintenance and attention due to the risks involved. You always want to make sure the system is working well and is safe to use. Heat pumps on the other hand require only annual maintenance. 

While you should always hire a professional to do a yearly check on your heat pump, if you are interested you can learn how to do it yourself.

Low cost to maintain and run

Additionally, the cost of the yearly maintenance and running of a heat pump is far lower than any other heating system, such as fireplaces, and furnaces. This remains another important advantage of heat pumps, and it helps your family’s budget.

Extremely efficient

Perhaps the main reason why homeowners invest in heat pumps is due to their extreme efficiency. Heat pumps are able to use electricity and turn it into 300% as much heat, making it the most efficient heating system available today.

While your electricity bill may be slightly higher if you have a heating pump, heating your home will be a lot more expensive if you compare it with conventional heating systems.

Safer

One of the reasons families opt for heat pumps is due to how safe the system is. While gas-powered heating systems are always a little dangerous, heat pumps on the other hand are the safest option available on the market. The only major risk with heat pumps is if one of your family members has an allergy to a substance that gets into the airway system.

Provides both heating and cooling

Heat pumps also allow you to either heat or cool your home, while other systems are only able to heat. This is why it is far more practical to have just one system that is able to do both the heating and cooling, than having a fireplace, a furnace, and then an air conditioner on top of that. Additionally, having two systems might even be more expensive to buy, maintain and run over the long run.

Improves the air quality of your home 

Since a heat pump is able to remove humidity from the air, it acts as a dehumidifier, improving the quality of the air in your home. This is especially important if one of your family members has asthma, and it can be an important way to improve air quality for them. It has been proven that humidity can affect people suffering from arthritis, allergies, and even eczema.

It lasts a long time

A heat pump is also a very reliable and long-lasting system, with some models and types of heat pumps lasting nearly 30 years. This obviously depends on the model, and how well it is preserved, but overall it is a system that outlasts other conventional options.

Low environmental impact

Finally, one of the reasons why heat pumps have become so popular is that not only are they extremely efficient but they also have a lower carbon footprint and environmental impact. Since the sustainability of planet earth is in our hands, choosing a system that will help you sustain our planet is of the utmost importance.

Heat pump disadvantages

You need a permit and license

Depending on where your house is located, you may need a permit and a license to be able to install your heat pump. This is why you should always contact a reliable and professional company to install your heat pump. They will be able to inform you of all the necessary documents and things you need to have in order before installing your system.

It may require construction work

Since heat pumps require air to flow outside and inside the house, you may have to drill some holes in the facade of your home. This may not be ideal, especially because the location of these pipes is fundamental to increasing the efficiency of your heat pump. This may also increase the installation cost.

Large investment upfront

Perhaps the single biggest disadvantage of heat pumps is the fact that it requires a large investment upfront. Depending on the type of heat pump, the costs can be as high as $40,000 for geothermal heat pumps. 

This is a price that not every homeowner is able to afford, and therefore prices some people out of this efficient system. Due to the high cost, some homeowners also question whether or not investing in a heat pump can actually help them save money.

Requires professional installation

Installing a heat pump is not as easy as installing a furnace, an aircon, or a fireplace. Everything needs to be considered, from the location of the heat pump to the orientation, and whether or not it is level. 

These aspects directly influence the efficiency and electricity consumption of a heat pump, and therefore installing a heat pump should be done by a professional company with years of experience. They will know exactly where to place the heat pump so that it can be as efficient as possible while lasting a long time.

Avoid thinking that installing a heat pump is a simple DIY project because it is not, and if you install a heat pump without any previous experience, you may run into future problems, it might not be as efficient as it can be, and it can last fewer years.

Snow can damage the system

In extreme weather conditions, heat pumps are prone to failure, and end up being damaged. For instance, snow can damage your heat pump system, especially if the unit is completely covered in snow. This is why if you live in colder weather you should consider having a heat pump cover because it protects the system from snow being in direct contact with it. Additionally, you also need to place your heat pump in a location where snow will not fall near it.

It will increase your electricity bill

While one of the biggest advantages of heat pumps is their efficiency, the truth is that after installing and running this type of system you may notice an increase in your electricity bill. This is normal because a heat pump requires energy to be able to operate, and whether you use an air conditioner or a fireplace they will have costs just like a heat pump.

However, you should be aware of the added electricity cost of running a heat pump.

Power outages render it useless

While some heating systems do not require electricity and can be used pretty much in any condition like a fireplace, a heat pump without electricity is useless. Since the system requires power to be able to function, you should consider that your heating and cooling will not work during power outages.

If you happen to live in a very remote location where power outages are more common, you should consider this before getting a heat pump, or you can always invest in a generator to make sure your heat pump works whether there is power from the grid or not.

Installing a heat pump can drastically change your outdoor space

One of the few aspects that are often overlooked about heat pumps, is how drastically they can change your outdoor space. Choosing the most optimal location for your heat pump means that it can be an area of your yard, that you didn’t want to see used by this bulky unit. However, you need to understand that you may have to sacrifice the layout of your outdoor space, to have a heat pump that lasts longer and is more efficient.

Heat pumps can be noisy

While most heat pump systems are relatively noiseless, depending on the type of heat pump and size it can be rather noisy. This can be a problem, especially if you have neighbors. Always check the local laws to make sure you are placing your heat pump at the correct distance from your neighbor’s house.

Maintenance needs to be done by professionals

While you can certainly learn how to maintain a heat pump, it is always wiser to hire a professional company specialized in this type of service. A heat pump is fairly costly, and you want to hire professionals to maintain and care for your system. 

Is a heat pump worth the investment?

After reading all of the advantages and disadvantages of heat pumps, you may be wondering whether or not you should invest in it. The truth is that a heat pump is one of the best solutions for your home, because it is highly efficient, allows you to heat and cool your home, and saves you money over the long term while being safer than all the other available options.
