Residential Geothermal


About the Building

Single-family home

Property Upgrade Summary

Installation of closed loop geothermal system with two loops and water furnace.

Geothermal heat pumps are considered a form of high efficiency heat pump. These systems rely on heat transfers between the air and the ground to provide heating and cooling to homes and buildings.

About the Project

Stockbridge at Tanglewood Condominiums became the first local commercial entity to use a loan under the Small Business Energy Savings Support product to improve its operating budget and gain savings.  The Association worked closely with the Montgomery County Green Bank and City First Enterprises to secure a $44,000 loan.  New LED fixtures on the property are reducing energy consumption by 100,000 kWh per year and saving over $14,000 annually.  The contractor worked closely with Pepco to secure substantial incentives that help offset the costs of this project.

About Geothermal

A geothermal system is similar to a conventional heat pump heating and cooling system.  A conventional heat pump, also known as an air source heat pump, takes heat out of the air and moves it into the home in winter and out of the home in summer.  A geothermal heat pump, also known as a ground source heat pump, is a high efficiency type of heat pump which uses the earth’s stable temperature to heat and cool the home.  Geothermal systems have pipes that are buried in the ground in which a liquid is circulated through. The liquid transfers the heat from the earth and moves it into the house during winter and removes heat from the house and transfers it into the earth in the summer.
