Key Takeaways

  • Electric/Infrared Radiant Heating is the most efficient home system currently available in the US
  • Geothermal and Air-Source Heat Pumps are capable of up to 400% energy efficiency meaning they produce four units of heat for every unit of electricity consumed
  • Modern Gas/Oil fuelled heating systems with condensing boilers can reach up to 94%+ energy efficiency
  • While traditional heating systems aren’t as efficient as radiant heating or heat pumps, they are often more affordable with a significantly lower cost to purchase and install

While some people consider solid-fuel burning stoves as a good choice for their home, they are not energy efficient and pose a significant risk to health.

Understanding Energy Efficiency

According to trusted sources like the U.S. Department of Energy (DOE), improving energy efficiency in residential buildings can have a significant impact on energy consumption.

In fact, the DOE states that residential buildings account for approximately 20% of total energy consumption in the United States.

This highlights the importance of implementing efficient heating systems to reduce energy demand and promote a more sustainable future.

To assess the efficiency of heating systems, it’s essential to consider metrics such as Annual Fuel Utilization Efficiency (AFUE) and Coefficient of Performance (COP).

AFUE measures the efficiency of gas or oil-fueled heating systems, indicating the percentage of fuel that is converted into usable heat. A higher AFUE rating implies greater energy efficiency.

On the other hand, COP is used to measure the efficiency of heat pumps, representing the ratio of heat output to the amount of electricity consumed. The higher the COP, the more energy-efficient the heat pump.

Now let’s explore the most efficient heating systems for your home, backed by trusted sources and reliable information.

The 4 Best Ways to Heat a House

Radiant Heating Systems

Radiant heating stands out as one of the most efficient choices for keeping your home warm and cozy during the colder months. It operates by emitting heat directly from a warm surface, such as a floor or panel, to objects and individuals in the room. Unlike forced-air systems that rely on blowing heated air, radiant heating ensures even heat distribution throughout the space, eliminating cold spots and drafts.

Radiant heating systems have an average AFUE rating of 85% to 90%, indicating their high energy efficiency. This means that 85% to 90% of the fuel or energy consumed is converted into usable heat, resulting in lower energy waste and reduced heating costs.

Underfloor radiant heat, in particular, offers exceptional energy efficiency.

The National Renewable Energy Laboratory (NREL) states that underfloor radiant heating systems can reduce energy consumption by 10% to 30% compared to forced-air systems – with some such as Green waves step heat radiant heat mats being 30-60% more efficient than traditional heating methods.

This energy savings is achieved by maintaining a lower ambient temperature while still providing the desired level of comfort.

Radiant heat panels also contribute to energy efficiency in homes. According to a study conducted by the Oak Ridge National Laboratory, radiant heat panels can achieve energy savings of up to 50% compared to traditional heating systems, primarily due to their ability to provide targeted heating in specific areas.

By incorporating radiant heating systems into your home, you can experience optimal energy efficiency, enhanced comfort, and reduced heating costs.

Geothermal Heat Pumps

Geothermal heat pumps utilize the constant temperature of the earth to provide efficient heating and cooling for homes. These systems transfer heat between the ground and the indoor space, making them highly energy-efficient.

The DOE highlights that geothermal heat pumps are one of the most efficient heating and cooling technologies available today, capable of providing 300% to 400% efficiency in heating mode. This means that for every unit of electricity consumed, the system can deliver three to four units of heat.

Additionally, geothermal heat pumps offer significant energy savings compared to traditional heating systems. The International Energy Agency (IEA) reports that geothermal heat pumps can reduce heating energy consumption by 30% to 70% and cooling energy consumption by 20% to 50% compared to conventional systems.

By harnessing the earth’s natural heat, geothermal heat pumps provide a highly efficient and environmentally friendly solution for heating and cooling your home.

Air-Source Heat Pumps

Air-source heat pumps are another very efficient heating option for homes. These systems extract heat from the outdoor air and transfer it indoors, providing both heating and cooling capabilities.

Lille geothermal heat pumps, air-source heat pumps can also achieve heating efficiencies of 300% to 400%.

Air-source heat pumps offer significant energy savings compared to conventional heating systems – they can reduce energy consumption for heating by 30% to 50% compared to electric resistance heating systems, such as baseboard heaters or furnaces.

Consequently, air-source heat pumps have to be considered as one of the most efficient heating systems for any home.

Gas and Oil Fueled Heating Systems

Gas and oil fueled heating systems, such as gas furnaces and oil boilers, have long been prevalent in many homes. While they are not as energy-efficient or environmentally friendly as some of the previously mentioned options, they remain reliable and widely used.

According to the DOE, modern high-efficiency gas furnaces can achieve AFUE ratings of 90% or higher, resulting in reduced energy waste and lower heating costs. Similarly, high-efficiency oil boilers can have AFUE ratings of 87% or higher, contributing to improved energy efficiency.

Although gas and oil-fueled systems are not as efficient as radiant heating or heat pumps, they can still provide reliable and effective heating for homes. It’s important to consider factors such as equipment age, maintenance, and insulation to maximize the efficiency of these systems.


Energy efficiency is a crucial factor to consider when selecting a heating system for your home. By choosing efficient options such as radiant heating, geothermal heat pumps, or air-source heat pumps, you can reduce energy consumption, lower heating costs, and minimize your environmental impact.

According to the DOE, implementing energy-efficient heating systems can lead to significant energy savings and reduce greenhouse gas emissions.

Embracing sustainable heating technologies aligns with global efforts to combat climate change and promote a greener future.
