Air-to-Water Heat Pumps. In addition to being the innovator of small duct high velocity systems, SpacePak is also the industry leader in air-to-water heat pump technology since we first introduced the modern hydronic solution to the North American market back in 2011.

Ductless Mini Split Heat Pumps Ductless mini splits are not susceptible to this waste, making them one of the best energy efficient heating and cooling systems available.

Before buying a heat pump system, it's important to know the potential downsides. Here are the cons of heating and cooling your home with a heat pump: Higher installation cost: Because heat pumps are more complex, they cost more to purchase and install than a comparable air conditioner.

Heat pumps today can reach 300% to 400% efficiency or even higher, meaning they're putting out three to four times as much energy in the form of heat as they're using in electricity. For a space heater, the theoretical maximum would be 100% efficiency, and the best models today reach around 95% efficiency.
