Air-Source Vs Absorption Heat Pumps

Posted on: 27 April 2016

If you are looking to get a new solution to your HVAC needs, then heat pumps are an excellent choice. To help you decide whether a heat pump is the right choice for you, here is a general explanation of how they work, along with a comparison of two of the most popular types of heat pumps:

How do heat pumps work?

The basic idea of heat pumps is that they can be reversed. They can act as air conditioners, but when it gets too cold, you can just switch them in the other direction and use them as heaters. This gives you a great deal of versatility, since you only need to get one appliance to handle your HVAC needs rather than two.

What is an air-source heat pump?

The most common type of heat pump is the simple air-source heat pump, which pretty much works just like a central air conditioner. There is a larger external unit that is used to vent heat outside your home during the summer, which is connected to the rest of your home via a system of air ducts.

Heat is added to the air, but the direction depends entirely on whether you are currently heating or cooling your home. When heating, the heat is taken from the air outside and dumped in the air inside your home. When cooling, the opposite happens, with heat from the air inside your home being dumped outside where it won't affect the temperature of your home.

What are the advantages of an air-source heat pump?

Few things are as simple to set up as an air-source heat pump as long as you already have ventilation set up. As long as you live in an area with relatively stable temperatures, an air source heat pump will give you great efficiency all year long. However, if you live somewhere that gets very cold in the winter (particularly if it drops below freezing), then an air-source heat pump won't be particularly efficient.

What is an absorption heat pump?

The idea of an absorption unit is that it runs on a form of energy that is not electricity. Propane and natural gas are both quite popular, but geothermal power and solar power are both valid choices as well.

In other ways, absorption units work similarly to other heat pumps. They exchange heat between the inside and outside of your home, which means that they can be reversed easily.

What are the advantages of an absorption heat pump?

If you are in a situation where electricity is not an ideal source of power, then an absorption heat pump is one of the best choices. For example, if electricity is expensive or unreliable in your area, then absorption could end up saving you a lot of money and stress.


Working with an HVAC Contractor to Care for Your System

As a homeowner, you know how important your HVAC system is for comfort throughout the year. If the air conditioner or heater is not working properly, it can result in higher energy costs as the system struggles to keep your home temperatures in a comfortable range. Working with an HVAC contractor will help you maintain your system for reliable use long term, and possibly help you cut your power bills enough to notice the savings at the end of the year.
