How efficient is a ground source heat pump?
Ground-source heat pumps consume 20-25% less energy than conventional heating or cooling systems, making them a more efficient way to heat your home. This type of pump is similar to an air-source heat pump because it does not use fossil fuels, helping to decrease fuel emissions. A big benefit of using a ground-source heat pump is that since the majority of it is underground, it is not dependent on outside weather conditions. This type of heat pump can effectively heat up a home, regardless of the temperature of the air outside. In addition, geothermal heat pumps feature a longer life cycle when compared to traditional heating systems.
What is an air source heat pump?
Air source heat pumps are installed outside your home and use the heat energy from the surrounding outdoor air to heat a room or house. Depending on the size of your property, there are 3 different types of air-source heat pumps you will need to be familiar with.
How does a heat pump work?
Comfort is essential to a home. A heat pump helps provide that warm air in the winter and cold air in the summer. Air or ground-source heat pumps could be a viable alternative to furnaces. When a heat pump is installed properly, it can deliver up to three times more heat energy to a home than the electrical energy it uses. Unlike a furnace, they transfer heat from the outside air to the inside rather than combust natural gas to generate heat.
What are the drawbacks of geothermal heat pumps?
The main drawback of a geothermal heat pump is that it has a high upfront installation cost, making it daunting for people to buy. They can also cost more money to install since soil needs to be dug up to install the pipe that is connected to the heat pump. An open-loop heat pump could also potentially contaminate the water that leads to your home. When it comes to choosing a heat pump, always consider the climate and environment you live in to decide which type of heat pump will pair best with your home.

Short-run ducted heat pumps use traditional large ductwork in a small portion of the house.
What is the difference between a ground source and air source heat pump?
Both air source and ground source heat pumps operate on the same premise: transporting heat into or out of the home. Unlike traditional heating systems like a fossil fuel furnace, heat pumps don’t generate heat – instead, they just move it.
Air Source Heat Pump
Much like a traditional air conditioning unit, an Air Source Heat Pump (ASHP) pulls heat from the air inside of the home and rejects it into the outdoor air. In winter, an ASHP can reverse its function and heat the home by absorbing thermal energy from the outdoor air and transporting it indoors.
Ground Source Heat Pump
A Ground Source Heat Pump (GSHP) draws stored heat from the ground and transports it into the home. In summer, a GSHP extracts heat from the air inside the home and expels it into the earth.
Installation: Excavation or Drilling?
GSHPs use buried ground loop system, there are two types: vertical and horizontal.
Ground Source vs Air Source Heat Pump: Lifetime and Maintenance
An ASHP requires similar maintenance to a standard air conditioning unit: changing the filter regularly, having a contractor clean the coil and vacuum the unit.
Ground Source vs Air Source Heat Pump: Cost
