For heat pumps to work at their best, it’s also important that the building has good energy efficiency installed, such as effective insulation. What different types of heat pumps are there? There are different types of heat pumps: air-source and ground-source. Heat pumps can also be paired...

How Do Heat Pumps Work?Champlin, DrewASHRAE Journal
An air fryer is a small kitchen appliance that uses convection to cook food. Convection is a type of heat transfer that occurs when warm air circulates around an object, causing it to cook evenly on all sides. Air fryers work by circulating hot air around food that has been coated in oi...
Where air-source heat pumps use electricity to heat (and cool),furnacescreate heat by burning a fuel source like natural gas or propane. They then distribute that heat throughout your home, to increase the indoor temperature. Furnaces are available in single-stage, two-stage, and modulating sy...
These are called water source heat pumps. One thing to note is that a compressor does not compress the liquid. If you ever get liquid refrigerant back to your pump due to a dirty evaporator coil or dirty air filter, then it will cause significant damage to the internals of the pump. A...
What happens to the heat? In the unit outside the building, there are lots of metal plates that dissipate the heat to the atmosphere. An electric fan blows air past them to accelerate the process. Over time, the heat inside the building gradually pumps away into the outside air. Photos:...
When hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. To keep cooling efficiently, the air conditioner has to convert the refrigerant gas back to a liquid again. To do that, a compressor puts th...
In water-to-air heat pumps, a fan blows air to be heated through this “air coil”. In water-to-water heat pumps, water which will heat the building flows through the condenser. Since the refrigerant is hotter than the air or water, it transfers heat to it. As it loses heat, the ...
True to its name, ductless heat pumps do not require any ductwork to heat and cool your home. For homes that do have ductwork, poorly sealed or poorly insulated ducts that leak heated air into unheated spaces can cost homeowners hundreds of dollars every year on their energy bills, according...
