My wife, Ralph & I are harshly environmentally conscientious. Both of us do our best to minimize our carbon footprint & protect our planet. Both of us both ride our bicycles whenever possible, & rely on public traninterestation when necessary. Ralph & I recycle, compost & grow our own fruits & vegetables. When all of us built our home, all of us spent extra cash to optimize efficiency. Although all of us live in an area which requires both heating & cooling for the majority of the year, our plan actually produces more energy than it draws. Both of us invested in a geothermal heat pump, despite the harshly high cost of replacement. The project was overpriced because of the excavation requirements. A loop plan was installed below grown to take advantage of the stable, year round temperature of the earth. The systems draws from this free energy source to transfer heat to & from the house. It does not burn any type of fossil fuel to generate heat. Because of this, the geothermal heat pump generates 4 units of energy for every 1 it uses. Both of us can actually maintain a comfortable year round temperature for around a dollar per afternoon. There are no red new home gases, carbon monoxide, fumes, or sizzling surfaces. It is clean, quiet, reliable, & low in repair. During the summer, the heat pump effectively combats humidity, & in the winter, it doesn’t overly dry the air. Throughout the year, the heat pump filters the indoor air, trapping airborne contaminants. To further trim costs & energy consumption, Ralph & I have recently added solar panels to generate power.
