Geothermal Heat Pumps Either water or a refrigerant solution circulates through the loop, picking up heat or releasing it as necessary. Geothermal systems provide the most efficient type of heating. They can cut heating bills by up to 70%.
Furnace and Boiler Systems
The U.S. Energy Department says furnaces and boilers are the most common heating systems in the country. According to David, they're also the most economical – at least those powered by natural gas. “Natural gas is still the least costly form of energy in most of the country,” David says.
Installation of electric heating systems is usually easier and less expensive than gas systems. Control over temperature settings also tends to be more exact when using electricity. The potential cost savings also comes from the shift to cleaner energy sources and their long-term efficiency.
Though common, oil systems are one of the most expensive ways to heat a home. Natural gas is cheaper, but there are some hidden costs to switching.
You can easily save energy in the winter by setting the thermostat to around 68°F to 70°F while you're awake and setting it lower while you're asleep or away from home.
As gas is generally cheaper than electricity – and modern gas boilers are more energy-efficient than their older counterparts – gas central heating systems are often the most cost-effective solution for heating your home. This is especially true when compared to electric heaters alone (read our gas vs.
Choosing a low-energy consumption heating system for your home. Here are some of the most commonly used low-consumption heating systems today: heat pumps, both geothermal and air source; pellet stoves and boilers; low-consumption electric radiators; and condensing boilers.
Reverse cycle air-conditioners provide convective heat and are the most energy-efficient heater and cooler of all types, irrespective of fuel source.
Ideally you should heat your home to a temperature of at least 18 °C. This is particularly important if you have reduced mobility, are 65 or over, or have a health condition, such as heart or lung disease. Having room temperatures slightly over 18 °C could be good for your health.
Generally speaking, Halogen heaters are one of the most inexpensive types of electric heater. They average around 1200W in terms of power output and because they provide instant-heat at close quarters, you shouldn't need to leave them on for long periods of time.
Heat pumps are more energy-efficient and versatile, providing both heating and cooling functions, while furnaces are typically more effective in colder climates. Ultimately, the best choice depends on your individual needs, your local climate, and the specifics of your home.
The average cost to install a geothermal heat pump typically ranges from $10,000 to $30,000, depending on factors like the size of the system, property location, and installation complexity. Horizontal loop systems tend to be less expensive, while vertical systems, which require deep drilling, are on the higher end.
Combining the best of both heat pumps and gas furnaces, dual-fuel systems are one of the best options for cold climates. These systems run primarily on the heat pump while the temperatures are mild. However, once the temperature outside drops far enough, a gas furnace takes over while the heat pump turns off.
Revolutionary heat pump technology
They use 75% of natural resources from the air, ground or a water source to provide heating and hot water comfort for your home. The remaining 25% is powered through electricity in order to operate.
On the one hand, keeping a constant temperature can be more energy-efficient in some cases because your HVAC system doesn't have to work as hard switching between temperatures. However, this approach can also lead to wasted energy if you're heating or cooling your home when no one can enjoy it.
In 2024, there are more options than ever, with models like ceramic heaters and oil-filled radiators that use less power while delivering effective heating. Ceramic Heaters: Known for their rapid heating and low power consumption, ceramic heaters are ideal for small to medium-sized rooms.
While geothermal and air-source heat pumps often rank highest in efficiency, other options like high-efficiency furnaces and wood pellet stoves can also provide significant energy savings.
The World Health Organization recommends keeping indoor temperatures between 64 and 75 degrees Fahrenheit for healthy people. The minimum temperature should be kept above 68 degrees Fahrenheit to protect the very young, the elderly, or people with health problems. Watch out for signs of hypothermia.
To save money, aim to have your temperature set around 68-72 degrees Fahrenheit when you're at home and awake. This is a comfortable temperature for most with the help of a light sweater. Overnight and when you're out, around 64 degrees Fahrenheit will keep your home at a good temperature.
