Geothermal Heat Pump Well Installation

For your home or small business, a geothermal heat pump system is an excellent way to save money. Unlike traditional HVAC, ground-source technology can provide winter heating and summer cooling from the same system. Despite the advantages, many homeowners still have a lot of unanswered questions. Some revolve around geothermal heat pump well installation.

A Well is Good, But a Geothermal Heat Pump Well is Better

Many rural American families live far from urban water systems, and rely on well pumping technology for fresh water. If you are in this demographic, you may wonder if a new geothermal heat pump will work with your existing well. It's a good question, since digging a new well is not an inexpensive proposition. The short answer is yes.

Now, that being said, there are a few things you need to know before you run out and put in a geothermal heat pump well.

Ground Water Consumption

A geothermal heat pump installed on an open loop relies on ground water to complete its heating and cooling cycle. This installation makes a thirsty machine that can require up to 1.5 gallons per ton of operating capacity per minute. If your well can't sustain that level of supply, then a geothermal heat pump installation will have to use a closed loop. Also, bear in mind that your well will have to supply the geothermal heat pump at the same time it supplies your typical household requirements. Some wells may not be able to keep up.

Ground Water Quality

Local mineral composition, soil quality, and pH level all play an important role in determining ground water chemistry. This chemistry must be compatible with the geothermal heat pump or the system may become damaged and inoperable. If local water quality isn't high enough, an open loop installation is unsuitable. After all, there is no point in using an open loop, if the water will corrode the system into uselessness.

Local Restrictions

Be sure to check all local laws before you install a new geothermal heat pump on your property. For one reason or another, many municipal authorities do not allow open loop systems. So even if your well could support an open loop, local ordnance may not allow the operation.

The last thing you want is to discover you ran afoul of the law after installation. This could lead to a costly redesign, not to mention any potential legal situation that could arise. Court costs are typically not cheap.

And Finally

If your property and well meet the qualifications, should you go geothermal? We definitely think so. Open loop geothermal can save a lot, just a ton, of money. When you already have the well excavated, installation is going to be way cheaper. Basically, this is a a no-brainer.
