Benefits And Drawbacks Of Air Source Heat Pumps

An air source heat pump is a great way to keep warm when you need it most. They’re designed to provide an alternative method of heating and cooling your home, but they can also be used in conjunction with traditional HVAC systems or as stand-alone units for more efficient use. 

What Is an Air Source Heat Pump?

Õhksoojuspumbad saaremaal (Air source heat pumps in Saaremaa) operates by transferring heat from an enclosed space to the outside air. This heats radiators and provides domestic hot water through wet central heating systems. Like a refrigerator, heat pumps absorb heat and transfer it to another medium.

An air source heat pump uses the same principle as a standard heat pump, but instead of using electricity to run the compressor, it uses outside air to do so. This means that there’s no need to have access to power and an electric grid; just make sure that your outside air intake venting is working properly.

The main difference between these two types of heat pumps is that the air source version has its own dedicated ventilation system that allows air to flow from outdoors into the building where it will be warmed or cooled by the unit. The other type would require ducts to transport conditioned air through the house.

When selecting this type of heat pump, it’s important to consider the size of your home because larger houses will require larger air intakes. If you plan on using this machine alone, then you should select one that works well with the space available to you.

Benefits of Using an Air Source Heat Pump

There are several benefits to installing an air source heat pump over a gas furnace or oil heater. Let’s take a look at a few of them:

  • No Fuel Costs

One benefit to having an air source heat pump is that you don’t have to pay fuel costs each month. There are some exceptions such as in Alaska where homes can only rely on natural gas and propane, which makes air source heat pumps a much better option.

  • Energy Efficiency

With an air source heat pump, you’ll save money on energy bills. This is due to the fact that they operate much more efficiently than their counterparts. In addition, unlike many HVAC systems, they won’t have any trouble with condensation during winter months.

  • More Comfort

An air source heat pump is often described as “quiet” and “efficient”, which is exactly what you want in a machine that will be in constant use throughout your entire household. Because they aren’t affected by temperature fluctuations, they work at a consistent level all year long, resulting in less fluctuation in temperatures.

In addition, they are quiet and don’t have any fan noise. So if you live with young children, or have pets that might become startled by loud noises, these machines are perfect for you.

  • Ease of Installation

These units are typically small enough to fit in areas where regular HVAC systems won’t go. For example, if you live in an older home, you probably don’t have enough room or budget to install a new central air conditioning system. However, you could easily add an air source heat pump to the existing vents without needing to make major structural changes.

They are very easy to install and don’t require any additional permits. Since they’re not powered by electricity, there’s no need for extra electrical wiring either. Simply plug it in and you’re good to go!

Types of Air Source Heat Pumps Available

So, now that we’ve covered some advantages of an air source heat pump, let’s take a look at a few of the different types on the market today.

  • Mini Split Air Conditioners

Mini splits are considered the smaller version of split air conditioners. Although they’re still large compared to window AC units, they’re much easier to install and are a lot cheaper to purchase.

These machines come in both single stage and multi-stage models. Single stage units have a single evaporator coil while multi-stages have two or three coils separated by a wall.

Multi-stage mini splits are slightly more expensive than single stage, but also produce far more cooling capacity. Multi-stage units can cool up to 1,000 square feet of living space.

  • Window Air Conditioners

Window air conditioners are a great choice for those who don’t have enough outdoor space to install a mini split. Instead of being installed outside, however, these units are placed inside a window. These units can also be found in both single and multi-stage varieties.

Single stage units feature a single evaporator coil and can cool up to 300 square feet of indoor space. Multi-stage models can cool up to 500 square feet of space.

  • Wall Mounted Air Conditioners

Wall mounted air conditioners are similar to window units in that they are positioned indoors. But, because these units must be placed against a wall, they are much larger than window units. These units can cool up to 2,500 square feet of indoor space.

  • Central Air Conditioners

Central air conditioners are larger than window models and are installed in an attic or basement area. They are generally installed above a forced air furnace and can cool up to 3,000 square feet of living space

How Do I Choose an Air Source Heat Pump?

Once you know what kind of climate you live in, you’ll be able to narrow down your options a bit. If you live somewhere in the temperate zone, like the United States, you’ll likely find yourself choosing between an air source heat pump and a mini split.

If you live in a colder environment, though, you may want to opt for a central air conditioner or a window unit.

However, regardless of climate, it’s always best to consult a professional before purchasing anything. They can help you select the right equipment based on your needs.
