The High Performance Home

Energy Efficient

Stop paying a fortune on your energy bills and reduce your carbon footprint. OakWood can provide recommendations on energy reducing options all the way to building a net-zero home which can produce as much energy as it uses.

Heat Pumps

A ground-source heat pump uses the earth or ground water or both as the sources of heat in the winter, and as the “sink” for heat removed from the home in the summer. For this reason, ground-source heat pump systems have come to be known as earth-energy systems (EESs). Heat is removed from the earth by using a liquid, such as ground water or an antifreeze solution; the liquid’s temperature is raised by the heat pump; and the heat is transferred to indoor air. During summer months, the process is reversed: heat is taken from indoor air and transferred to the earth by the ground water or antifreeze solution. A direct-expansion (DX) earth-energy system uses refrigerant in the ground-heat exchanger, instead of an antifreeze solution.

Why this product is important:
Geothermal systems provide the following benefits to the home owner: – Lower operating costs (HIgh efficeincy furnaces are up to 94% efficient. Geothermal Heat pumps are up to 400% percent efficient because they transfer heat rather than creating it by burning something. – They are celan and safe They don’t burn carbon to create heat so they don’t emit greenhouse gases.

Reference:
Ideal for larger homes and older larger homes.  Consider maximizing insulation first.
