aa It’s a proven technology that’s been used for decades, but it’s still truly revolutionary: heat pumps provide affordable comfort all year round, heating in the winter and cooling and dehumidifying in the summer. They’re safe and clean. They produce no fumes, use no fuel, and even filter the air as they offset your other, usually costlier, fuel source to save you money.
You’re already familiar with how heat pumps work – your fridge is a heat pump, and so are air conditioners. The heat pumps that heat your home cycle refrigerant through coils, just like your fridge does. The refrigerant absorbs heat from its surroundings in one coil; then a compressor pumps it to another coil, where it releases that heat.
During the warmer months, heat pumps work in reverse to keep your home cool and comfortable by moving heat and humidity from inside your home, outside. The heat pump unit acts as a fully equipped air conditioner. They’re reliable, efficient, and offer the best of both worlds with heating and cooling benefits all in one system.
Air-source heat pumps transfer heat energy from the air outside your home to the air inside. They’re very efficient, and work down to as low as -27°C. As the outdoor temperature drops, you may need to use your alternate heat source. There’s more than enough warmth in the air on a typical Nova Scotia winter day for a heat pump to heat the average home. Air at -18°C still contains about 85% of the heat energy it contains at 21°C.
