Looking For A More Natural Heat Source? Consider These Geothermal Heating Options

Heating your home can be expensive, particularly if you're using electricity or heating fuel. Luckily, these are not the only heating options. If you're looking for a more efficient and cost-effective choice to heat your home, you should consider investing in a geothermal heat system. Geothermal units draw heat from the ground and cycle it through a system into your home. Here's a look at three different types of geothermal heat systems you can consider if you're thinking about making the change.

Closed Loop Geothermal Heating

When it comes to geothermal heating design, closed loop systems are one of the most common designs. These heating systems rely on a series of underground pipes circulating water in a perpetual cycle. The length of the pipe network will vary based on the ground temperatures, soil moisture levels and thermal conductivity of the land around the house. In most cases, these units draw their water from a nearby natural water source or from a constructed reservoir.

  1. Pond Loop – A pond loop is a closed loop geothermal system that draws its water from a nearby pond or similar water source. The water source needs to be deep enough to place an underground coil system into the water supply. The depth needed will vary based on how much pipe you need and the average water temperature. Once the coils are at the base of the water supply, the system draws water in over the coil system and routes it through the pipes in a continuous cycle.  
  2. Horizontal Loop – A horizontal loop is a popular choice for many homeowners. If you're looking for a heating system that you can contain on your property without a pond or other natural water source, this may be the right one for you. You'll need enough land to be able to lay several sections of pipe into shallow trenches. They'll form a horizontal loop shape and typically will cover most of your yard. These systems draw water from a reservoir you establish.  
  3. Vertical Loop – Vertical loops are another ideal option if you don't have a pond you can use for a water source and your yard isn't large enough to support the pipe system of a horizontal loop. In this system, the pipes are installed vertically in a U-shaped design. They're typically installed into a well that draws from that water to heat your home. The depth of the system will vary based on your property's ground conditions, but it's a great choice when you have limited yard space.
