When my husband and I were in the process of building our new home, we considered all different types of temperature control systems.
Because of the weather in our local area, we wanted a system that would provide both heating and cooling. We hoped to avoid sacrificing too much space and aesthetics to bulky equipment. Energy efficiency was also a big priority for us. Not only were we looking to keep our monthly costs as low as possible, but we are concerned over our impact on the environment. It’s important to us to minimize greenhouse gas emissions. A geothermal heat pump provided the perfect solution to all of our requirements. The only problem was the initial investment. A geothermal system is far more expensive than any other type of temperature control. The cost for installing the underground loop system, because of the necessary excavation, added up to $20,000. The cost was a bit overwhelming to undertake. However, we looked into the saving from tapping into the renewable energy source in our backyard and realized we could recover the investment in under five years. The geothermal system takes advantage of the stable year round temperature underground. Rather than burn fossil fuels to create heat, it simply moves existing heat between the ground and the home. This process is extremely efficient, clean and quiet. We are able to maintain perfect temperature all year round for approximately a dollar per day. Plus, we have much longer to recover our investment because of the exceptional lifespan of the system. We can expect the underground loop to last around 100 years and the indoor heat pump should provide reliable operation for over twenty years.
