Variable stage heat pumps cost more than either single or two-stage heat pumps but can experience higher repair costs due to their complexity and only average durability. Energy is not created as part of this process - when 1 unit of electricity is consumed to deliver 4, it means that 3 units of energy are absorbed from the ground.Ĭombustion-based systems like oil-furnaces, however, are unable to reach even 100% efficiency because they always deliver less energy than they consume.Ī geothermal heat pump contains 3 primary components:Ī variable-stage heat pump can vary its levels of intensity incrementally.Īs a result, these units rarely shut off while maintaining a consistent temperature and excellent efficiency. ![]() ![]() That means for every 1 unit of energy used to power your geothermal system, 4 units of heat energy are supplied to your home. On average, geothermal heat pumps are 400% efficient. A heat pump is also the only heating and cooling machine with a COP above 1! The higher the COP and EER, the less electricity (and money!) used to operate the machine, but the higher upfront cost to purchase it. ![]() Geothermal systems generally have COPs between 3-5 and EERs between 15-25. COP indicates the ratio of heat produced to the amount of energy used to produce it, whereas EER indicates the amount of heat removed from your home to the amount of energy used to remove it. Two measurements are used to calculate the efficiency of a geothermal heat pump - Coefficient of Performance for heating (COP), and Energy Efficiency Ratio for cooling (EER). This means our customers see a faster return on their investment. We chose to build a 2-stage heat pump because it provides a lot of efficiency without the additional expense that comes with a variable-stage pump. When designing the Dandelion Heat Pump, we wanted to balance quality, efficiency, and cost. All three loop types can be equally efficient when installed properly, but the cost can vary widely due to the factors explored below. The most appropriate loop type for your home primarily depends on the amount of land available (and whether or not you have a pond on your property!). Because this type of ground loop requires a water source on the property, it’s relatively uncommon, and we don’t discuss it in detail. Each hole is 6 to 8 inches in diameter, and if you have more than one, they’re about 20 feet apart.Ī pond / lake ground loop is installed in a nearby pond or lake with adequate size, depth, and flow. There are three types of closed loop geothermal systems: vertical, horizontal, and pond / lake.Ī horizontal ground loop is installed over a wide area of ground and requires enough space to dig trenches hundreds of feet long and 6-10 feet deep.Ī vertical ground loop is installed in one or more boreholes about 200 to 500 feet deep in the ground. Since all of these steps are done in-house, we are able to offer all-in-one pricing, which gives homeowners the best customer experience and no cost surprises as the project is being completed. While a virtual energy consultation and site survey is the best way to get an accurate quote, the following information will get you started.ĭandelion oversees all 3 stages of geothermal installation: drilling and installing the underground loop, connecting the ground loop to your home, and installing the heat pump where your furnace used to sit. We created this guide to serve homeowners interested in geothermal, whether you’re just browsing, evaluating your options, or in the midst of making a decision. In short, these numbers can set false expectations for potential geothermal buyers. In case you’re in a hurry, click here to skip to Dandelion Geothermal’s price.įor example, some online resources only provide the price of the heat pump, without factoring in drilling, installation, or trenching-essential components that account for 55% to 75% (or even more!) of the total system price. Without this knowledge, it’s difficult to understand the value of a geothermal installation or feel confident you’re paying a fair price. Many articles present extreme price ranges with little insight into the factors that affect the price of the system. It’s easy to feel frustrated while researching how much geothermal heating and cooling costs.
