Geothermal Heat Pump Services

Many homes in the St. Louis, MO area have a central air conditioning system and a furnace to keep their homes comfortable in different seasons. As your heating and cooling systems age, you might start to wonder if there are more energy-efficient ways to control the climate in your home. Geothermal heating systems are green technology that can both cool and heat your home by using the energy from the earth. They do not use fossil fuels and consume very little electricity.

Many homeowners all over St. Louis are making the switch to geothermal heat pumps for their homes. If you’re interested in learning more, talk to Welsch Heating and Cooling today.

What is a Geothermal Heat Pump?

A geothermal heat pump is a type of heating and cooling system that relies on the temperature of the Earth beneath the top layer of soil to keep a home comfortable. Geothermal heat pumps have been used since the 1940s, and are continuing to grow in popularity with some 50,000 geothermal heat pumps located across the United States. These heat pumps work by installing a loop system with tubing installed in bore holes 150-300 feet deep.

These pipes and the fluid within exchange heat energy from the soil that is cool during the summer and warm during the winter. The temperature and energy of the earth is then used to heat and cool your home using a closed-loop system of pipes. The pipes are then connected to pumps inside your home. The fluid in the tubing gets pumped through the indoor heat pump which removes heat in the summer and adds heat in the winter.

Are Geothermal Heat Pumps Different that Air-Source Heat Pumps?

When it comes to the indoor and outdoor units, geothermal heat pumps work similarly to air-source heat pumps. However, unlike an air-source heat pump, a geothermal heat pump does not rely on the temperature of the outside air for heat.

In addition, geothermal heat pumps take a little more planning to install. That’s because a piping system needs to be installed outside your home. Depending on the soil around your home and other environmental factors, your technician will be able to inform you of the best methods to install a geothermal heat pump.

The installation process can be a bit more invasive than a traditional heat pump, but is well worth the investment for homeowners that want a reliable, environmentally-friendly, and energy-efficient heating and cooling system in their St. Louis, MO home.

Benefits of Installing a Geothermal Heat Pump

If you’re looking for a new heating and cooling system for your home, geothermal heat pumps might be one of the better options for some homeowners. Some of the many benefits of installing a geothermal heat pump include:

  • Maintenance schedule – Just like your air source heat pump, geothermal heat pumps have the same maintenance schedule. You’ll want to maintain your geothermal unit twice a year. Once in the spring and again in the fall.
  • More efficiency and energy savings – Since the temperature of the Earth’s soil stays constant and is reliable even in harsher climates.
  • Less noisy – Geothermal heat pumps run much quieter than air source heat pumps.
  • Longer Lifespan – The indoor air handler for your geothermal heat pump can last for 25 years, and up to 100 years for the underground piping system.
