My husband, Nate, & I strive to be as environmentally responsible as possible. Both of us sold a single of our vehicles & either take public moveation or ride our bikes the majority of the time. Both of us compost all of our organic scraps, turning them into a natural fertilizer for our gardens. Both of us grow the majority of our own vegetables & use no chemical pesticides. When building our home, energy efficiency was seriously crucial to us. Nate & I spent hours researching all unusual types of heating & cooling systems. Both of us were looking for an Heating & A/C program which would handle the serious weather in our area without contributing to the problem of redloft gas emissions. Both of us hoped to avoid the dangers of combustion byproducts, such as formaldehyde & carbon monoxide. Both of us didn’t want a program which consumed a great deal of electric. The Environmental Protection Agency considers geothermal heat pumps as the most environmentally friendly heating/cooling program on the market. This type of temperature control requires a immense initial start up cost, however recovers the initial investment through tremendous energy savings. The expense of installation is mainly due to the necessary excavation for the underground loop system. However, the underground loop should last for upwards of fifty years & takes advantage of the free energy source in our own backyard. The geothermal heat pump burns no fossil fuels, however simply moves heat from a single location to another. Both of us are able to heat & cool our immense loft for around thirty dollars per months. Both of us have greatly reduced our carbon footprint, & yet love a clean, safe & effective heating/cooling system.
