Air Source Heat Pump (ASHP)
An Air Source Heat Pump captures heat from the outside air and transfers it inside. Now of course this is simplified but the good folks at Cook’s Plumbing, Heating and Air Conditioning are experts on how they work, where they are best suited and most importantly, how to install and maintain them to their peak performance. So call Cook’s today and see if an Air Source Heat Pump (ASHP), which provides low cost space heating and up to 4 times more heat than an electric heater for the same amount of energy is the right solution for you.
The technology is similar to a refrigerator or freezer or air conditioning unit: the different effect is due to the physical location of the different system components. Just as the pipes on the back of a refrigerator become warm as the interior cools, so an ASHP warms the inside of a building whilst cooling the outside air.
The main components of an air-source heat pump are:
- An outdoor heat exchanger coil, which extracts heat from ambient air
- An indoor heat exchanger coil, which transfers the heat into hot air ducts, an indoor heating system such as water-filled radiators or underfloor circuits and/or a domestic hot water tank
Choose from a Mr. Slim ductless heat pump and not only get the convenience of ductless but is up to 319% more efficient than many traditional heat pumps. Or see how the every popular ZubaCentral pump will provide sufficient and efficient heating to -30 Celsius.
The Lennox XP25 uses revolutionary Precise Comfort™ technology to maintain an ideal temperature and perfect humidity under any conditions, all while saving you hundreds of dollars in energy costs.
Mitsubishi Zuba Cold Climate Systems
All Zuba Cold Climate Heat Pump systems are powered by VCSi technology. This allows you to achieve consistent temperatures throughout your space while saving you up to 50%* in energy costs. With Mitsubishi technology, the Zuba system offers heating and cooling solutions that can be customized for your home. All electric systems can be centrally ducted or a combination of ducted and ductless becoming an efficient solution for buildings that don’t have full duct systems or areas that aren’t efficiently heated/cooled.
• 2 – 3.5 ton sizes available
• Heats to -30°C or -22°F
• Whisper quiet operation; outdoor units operating as low as 47 db (close to a bird chirp)
• Compact Horizontal Discharge Outdoor Unit
• 10-year parts and compressor warranty

Zuba Cold Climate Systems also offers a hybrid solution, where the heat pump is paired with an indoor coil and fuel burning furnace (typically gas or propane). This option is designed to switch over from the heat pump to the furnace when the outside temperature drops to a set temperature where it is more efficient to operate the furnace.

• 10-year parts and compressor warranty
Lennox Heat Pump Solutions
Lennox High-Efficient Heat Pump solutions can be paired with an air handler for all electric system or with a coil and furnace for a hybrid system. While compatible with all furnaces, best results and efficiencies are received when paired with a Lennox furnace. The Signature Series requires pairing with a Signature furnace and S40 thermostat for optimum results.
