Pump Up The Heat! (And Cooling!)
An economical and environmentally friendly solution for heating and cooling. Local utility rebates make Air Source Heat Pumps a highly cost-efficient component in net zero homes. Using electricity the outside air is either heated up by compression or cooled down by expansion before being distributed through the ERV (energy recovery system).
Heat pumps are a good choice for high performance homes—and maybe yours—because they heat and cool the air with less energy. They work by pumping heat from one place to another rather than generating it.
How does it work? Heat pumps compress and expand fluid to make it hotter or colder. Compressing a fluid, such as air, makes it hotter. Expanding a fluid makes it colder. Have you ever noticed how a spray can, like spray paint, gets colder as you use it? The can is soaking up heat from the air around it. Refrigerators work in the same way. You might notice the top of your refrigerator is warm. That’s because it’s giving off heat in order to cool the inside.
Since the envelope of the Next Generation Home is already highly effective in keeping the inside temperature stable, little electricity is needed to run the air source heat pump.
