This heavily wooded custom home lot in Bethesda Maryland needed several trees to be removed.  Patrick Musser Tree Service did a great job and managed a clean and safe site within a residential neighborhood   http://youtu.be/79z9d7RvuD4. The new home will commence soon.  We will update you with progress.

Faced with the task of heating and cooling a home of any size, geothermal systems make an incredible contribution to energy efficiency and practical applications.  Not only will they save money over time but they significantly reduce the demand on the electrical grid and the gas services in a community.   Given the energy issues in our world, its good to know that there are ways to make tremendous reductions in the carbon footprint of any new home or renovation.

In this project five wells were drilled to provide the heat exchangers with a water inflow that is roughly constant in temperature, about 50 degrees F.   Heat pumps work like a reversible refrigerator, sending the heat from ground water to the home in winter and swapping the heat from home back to the ground water in summer.alt Boilers work to boost the temperature of water. One of the wells prior to being connected to the home appears in the adjacent photo.

The following photos depict the installation of radiant heating systems that, by concept, date back to the Roman Empire.  When combined with geothermal systems, and today’s technology, radiant systems can drastically improve the comfort of modern living areas at a much lower energy cost.  Small tubing filled with heated water is recessed into prefabricated panels. altThe panels are mounted on the subflooring and contain an aluminum backing that radiates the heat of the water upwards.  The rooms will warm from the floor to the ceiling, heating the entire space. This will allow the owners to be comfortable at lower thermostat settings on the primary heating system.  This installation also helps eliminate cold feet syndrome – that malady that occurs when your body is warm, but your feet are freezing.alt

This system is installed in the kitchen and dining area, spaces where families and friends often congregate.  These flooring elements should be carefully coordinated with the cabinets, floor supply ducts and even flooring patterns in the tile and wood.

A great link that explains the physics behind geothermal: http://smart-nrg.com/geothermal.php Not only is this the "green" thing to do but it saves a lot of money in the long run.  You might check with your tax advisor about the incentives available for these installations.
