Geothermal HVAC units are rapidly growing in popularity in Sunnyvale, Texas, thanks to their energy-efficiency, cost-effectiveness, and environmental benefits. If you’re considering geothermal HVAC installation, you have four options: vertical closed-loop, horizontal loop, well water loop, and pond/lake loop.
Vertical closed-loop geothermal systems are typically installed on residential properties since they don’t require much land and have minimal effects on landscaping. To install a vertical loop, technicians will drill holes about 4 inches in diameter, 20 feet apart, and up to 400 feet deep. The loops connect at the top and bottom and attach to your home’s heat pump with a pipe.
Horizontal closed-loop systems require between 400 and 600 feet of looping space for every ton of heating and cooling capacity, which means you’ll need a large lot for this type of geothermal system. To install a horizontal loop, a technician will dig trenches between 3 and 6 feet deep where they’ll bury the loops. Due to the amount of space needed and the negative effects on landscaping they may have, horizontal loops aren’t as common as vertical loops.
Well Water Loop
If you have wells on your property, a well water loop is probably the most economical geothermal system for you. Well water loops are open-loop systems, meaning they have an entry point at one end and a discharge point at the other. To install, a technician will insert the access point — the component that draws water through the pipes and into the home’s heat pump — into the well. Then, the tech will install a submerged discharge pipe — the component that circulates water back into the ground — into the other well.
A pond/lake loop is a good, budget-friendly option for homeowners who have a pond or lake on their property. It’s a closed-loop geothermal system and does require some digging in order to connect the underground system components to the indoor components.
