How To Heat And Cool A Home At No Cost: The Benefits Of A Ground-Source Heat Pump

Blog

In a time of fluctuating energy costs, wise homeowners will look for ways to heat and cool their homes as efficiently as possible. While using a condensing furnace and a highly efficient AC system will help, you can do better if you using a ground-source heat pump to heat and cool your home will help you to save even more money. You may even be able to take your heating and cooling off the grid to save even more money. 

What Is a Heat Pump?

To understand what a heat pump is, you must first understand how an AC unit works. The key component of an air conditioner is the refrigerant running through it. As the evaporator fan inside your house pushes air over the refrigerant, it vaporizes and absorbs heat from its surroundings. Condenser coils outside your home then push the relatively cool outside air over the refrigerant to cool it down and condense it back to a liquid so that it is ready to repeat the process. By reversing the function of the coils, you can extract heat from the outside air to heat your home. Thus, with one unit, you can both heat and cool your home. 

What Does the Term "Ground-Source" Mean?

Standard heat pumps look just like an AC unit and push heat into the outside air to cool your home and extract heat from the outside air to warm your home. The problem with this design is that outside temperatures fluctuate wildly, which will affect the efficiency of your system. It will be its most efficient while air temperatures are moderate, but the hotter or colder it is outside, the less efficient your heat pump will be. A ground-source heat pump corrects this problem by burying specially designed coils in the ground outside your home. In this way, your system can tap into the more consistent ground temperatures, which will remain between 50-60 degrees year round. By way of comparison, an air-source heat pump will top out at about 275% efficient; whereas, a ground-source heat pump can be up to 600% efficient. 

How to Go off the Grid?

While 600% efficiency is impressive, you will still pay to heat and cool your home. If you want to go completely off the grid, you can do so with either an air-source or ground-source heat pump, which both run off of electricity. Thus, all you need to do is use solar panels or a wind turbine to provide your own energy for your system.

Heating and cooling a home are two of the most expensive bills that a homeowner has to contend with. A ground-source heat pump can help you to vastly reduce if not eliminate these costs, which makes installing one a wise choice for your home.

Preparing for a Steamy Summer

All of my life, I’ve lived in the southern United States. Because this area of the country experiences extremely hot summers, I’m vigilant about keeping my HVAC system working properly. Do you have an older heating and air conditioning system? Perhaps, you’re worried your HVAC unit won’t survive the upcoming, hot summer. If you can relate to this scenario, consider contacting an HVAC contractor as soon as possible. This professional can inform you whether you merely need to service your old HVAC system or invest in a new one. On this blog, I hope you will discover the most common tasks HVAC contractors do at residences. Enjoy!
