Frederick Net Zero Home
The heating system is a geothermal heat pump that also provides the hot water. Waste heat from the geothermal system heats the water for free in the summer. Ventilation is provided by an energy recovery ventilation system (ERV). The ERV provides a continuous supply of fresh air to the home while recovering the energy in the exhaust air to precondition the fresh air. All the lighting is LED and Energy Star rated appliances.
