Project Ideas


Types of Geothermal Heat Pump Systems
Larsen Plumbing & Heating installs three of the four basic types of ground loop systems — horizontal, vertical, and pond/lake closed-loop systems. The fourth type of system is the open-loop option. Which one of these is best depends on the climate, soil conditions, available land, and local installation costs at the site. All of these approaches can be used for residential and commercial building applications.
