BrHEAThe with Air Source Heat Pump

CCHRC is testing how an air source heat pump can be integrated with a heating and ventilation system used in high-efficiency homes in Alaska. This builds on the original BrHEAThe System, which uses an HRV to deliver heat from an oil-fired boiler to ensure homes receive adequate fresh air. CanmetENERGY-Ottawa funded initial research in 2016 and is supporting this new round of lab testing, which will take place at CCHRC's Research and Testing Facility.

BrHEAThe Evaluation In an effort to address these issues CCHRC developed the BrHEAThe system in 2011. BrHEAThe is a combined heating and ventilation system which uses one distribution system to provide fresh air and space heating to high-performance homes in cold climates.
Energy Recovery Ventilators (ERVs) in Cold Climates Energy Recovery Ventilators (ERVs) are whole house ventilation systems that exchange stale indoor air with fresh outside air, recovering both heat and moisture from the indoor air to save energy. They have the potential to improve indoor air quality in a cold dry climate like Interior Alaska.
Kenai Indoor Air Quality Study This project examined the most common causes of indoor air quality problems in Southcentral Alaska by monitoring 100 homes for carbon monoxide, carbon dioxide, temperature, relative humidity, and radon.
