The Benefits Of Geothermal Heating & cooling

Lower Cost of Ownership

  •  Geo systems last longer than traditional systems (DOE)
  • Drastically reduced HVAC related utility bills
  • Lower cost of replacement
  • Lower life cycle cost (read article)

Hot Water

  • Also provide hot water for your home by assisting your existing hot water system and adding to increased energy savings.
  • Provide radiant floor heating.

Typically Require Less Maintenance

  • All equipment is indoors not exposed to the weather
  • No more boilers, oil, and seasonal shutdowns and startups

Safer, Cleaner, and Quieter

  • Use sustainable energy from the ground and the sun
  • Reduce fossil fuel consumption & greenhouse gasses
  • No loud running outdoor unit

The Most Energy Efficient Way to Heat and Cool Your Home

According to the U.S. Dept. of Energy, geothermal is the most efficient form of heating and cooling: 1

Geothermal can reduce energy consumption anywhere between 25% to 50% compared to air-source heat pump systems.

Geothermal heat pumps reach high efficiencies (which = lower electricity bills):

  • In Heating – up to 300%-600% efficient over traditional air source heat pumps even on the coldest of winter nights. This is due to the fact that they do not have an outdoor unit, but instead rely on the consistent ground temperature to heat your home (which in this region is typically 55F year round). For every 1 unit of electricity consumed, the geothermal system is able to produce 4 or more units of heat for your home. Due to their relative inefficiencies, traditional air source systems cannot achieve these levels of comparative heating outputs. As a result, they must run longer and harder while at lower efficiencies costing you more money and in turn never achieving the comfort you seek.
  • In Cooling – geothermal systems are rated in EER when it comes to cooling efficiency ratings. EER rates a system on how well it can perform when it is 95F outside. Air source heat pumps are rated in SEER. That rating is based on how well they perform over the span of the cooling season when you will have less than 95F outside temperatures most of the time. But, in terms of comparison, using the simple conversion formula of EER to SEER (EER = 0.875 × SEER), geothermal ground source systems on average can reach 40 to 50 SEER! Even the highest efficiency air source heat pump systems with outdoor units only reach up to 24 SEER.

Side-by-side comparisons

The Trane 21 SEER 3 ton variable speed compressor air-to-air ducted heat pump only has a 13.5 EER. The 1 ton Daikin RXG ductless wall mount mini split is rated at 25 SEER, but only carriers a 14 EER rating.

The 7 series WaterFurnace geothermal system boasts a whopping 43.5 EER.

Geothermal most efficient heating
Geothermal ground source heat pumps do not depend on the the outside air and fluctuations in air temperatures in the winter, so they have shorter run times, do not rely so heavily on expensive backup electric heat, work under less stress, and therefore operate at increased efficiencies. This provides lower electricity consumption while at the same time actually improving indoor comfort by reducing indoor temperature swings.
Geothermal more efficient comparison to traditional heating and cooling systems

Geothermal is such an energy efficient renewable source for heating and cooling that the government offers generous financial incentives that pay for the system.

Ground Loops for Geothermal

Will my yard work for geothermal?

There are several ways to install the ground loop. One method is by installing the loop horizontally. Horizontal loops are not deep, but require more yard square footage.

Another method is installing vertical loops. These loops require less square footage and are drilled down to nearly 300 feet.

Installation of the Ground Loop into your home

For either method, the ground loop is brought into the house below grade. The loop is filled with a water and an anti-freezing agent, while the air is vented out.

The geothermal heating and air conditioning equipment is then installed inside the home, either in the basement or in another designated area.
