What is the most energy saving heater?

Author: Nicole Botsford  |  Last update: Friday, April 10, 2026

Both infrared and oil-filled heaters have the potential to be highly energy-efficient because they provide radiant heat rather than forced hot air. However, what is “best” for your situation comes down to room size, features, budget, and preference.

Which heater saves the most electricity?

Infrared heaters are the most efficient type of heater available. They use very little electricity to generate heat, and they provide a lot of heat for their size. Infrared heaters are also very safe to use, as they do not emit any harmful radiation. Oil-filled heaters are another type of heater that is very efficient.

What type of heater is the cheapest to run?

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.

How much does it cost to run a 1500 W heater for 24 hours?

Answer. To calculate the cost of running a 1500-watt heater for 24 hours in the US, you need to know the electricity cost per kilowatt-hour (kWh). If the average cost is about 16 cents per kWh (as of early 2023), the heater uses 1.5 kW x 24 hours = 36 kWh. Therefore, the cost would be 36 kWh x 16 cents = 5,76.

What is the most energy efficient heater system?

Reverse cycle air-conditioners provide convective heat and are the most energy-efficient heater and cooler of all types, irrespective of fuel source.

The Most Efficient Type of Space Heater

Which heater uses the least electricity?

Oil Heaters

They are silent, and super energy-efficient as most models have an inbuilt thermostat. These heaters are a little slower in reaching the temperature setting you select. But once there, they use precious little electricity as the thermostat takes charge, only drawing energy needed to retain the heat.

What is the cheapest way to heat a room?

What's the cheapest way to heat your home?
  • Gas boiler.
  • Gas boiler and solar thermal panels.
  • Oil boiler.
  • Electric combi boiler.
  • Air source heat pump.
  • Biomass boiler.
  • Infrared heating panels.
  • Wood burner.

Is it cheaper to run space heaters or central heat?

But in general, since central heating powered by natural gas is cheaper than heat from electricity, heating a large space will cost less with an HVAC system that runs on gas.

Are space heaters hard on your electric bill?

If you use a space heater in your home, please be aware that using a space heater can cause a significant increase in your monthly bill. A 1,000-watt space heater operating 12 hours a day will add about $40 to your monthly bill. If the cost does not deter you, remember how important it is to use space heaters safely.

Can I run a space heater 24 7?

Space heaters are designed to run for a few hours and warm a small space. These units aren't intended to run all day or night, operating without stopping for eight hours or more.

What heaters don't use a lot of electricity?

Oil-filled heaters use oil that's heated by electricity to create comfortable, radiant heat. Once the oil is heated, these can continue to provide warmth for a while, even after you turn them off, so they use less electricity overall.

Are oil-filled heaters cheap to run?

Oil filled radiators work in a very energy efficient manner, so can be considered cheap to run in comparison with many alternative designer radiator styles.

What is the cheapest most efficient heat?

Simply put, natural gas fired units are the least expensive to operate of all central heating units. When efficiency is considered, both gas and oil boilers are less efficient than electric ones. Of course the cost of electricity continues to increase so the overall cost may not be less than fossil fuel fired units.

Which heater is best for less electricity?

Infrared panels are the most energy-efficient electric heaters in our range because of the type of warmth they produce.

Do oil-filled heaters use a lot of electricity?

Oil filled radiators are more economical to run because they retain heatlonger and power demand through the temperature control is called upon less frequently. Electric heaters heat only the room you are in and not the entire house, providing extra heat only where required and helping to optimise energy consumption.

What are the disadvantages of a quartz heater?

Disadvantages of Quartz Heaters: 1. Safety concerns: Although quartz heaters are generally safe to use, they can pose a risk of fire if they are not used properly. The quartz tube can get very hot, so it's important to make sure that it is not touching any flammable materials.

Which heater is best for saves electricity?

Reverse cycle split system air conditioners (A.K.A heat pumps) – the most energy efficient electric heater. 5 and 6 star reverse cycle units can be even cheaper to run than gas heaters, producing just one-fifth of the greenhouse gas emissions that a standard electric heater creates.

Do small plug-in heaters use a lot of electricity?

On average, space heaters use 1,500 watts of electricity.

Using a space heater 8 hours per day will use about 84 kilowatt-hours of electricity per week. It costs an average of $51.65 to run a space heater for a month and $258.26 to run for a year.

What kind of space heater is most energy efficient?

Radiant heaters emit infrared radiation that directly heats objects and people within their line of sight, and are a more efficient choice when you will be in a room for only a few hours and can stay within the line of sight of the heater.

Is it cheaper to use a plug-in heater?

Savings using a space heater for 8 hours per day

Those with electric heat save less -- about $72 respectively -- and folks with natural gas, which is currently cheap, would pay about $36 more than if they ran a space heater.

How can I keep my heat bill low?

What is the most expensive way to heat a house?

This shows natural gas is the cheapest type of heating to run and heating oil is the most expensive way to heat a home.

Is there a solar powered heater?

Unlike traditional space heaters, many solar air heaters typically need to be mounted to a roof, wall, or window, in order to collect the sun's heat. Some of these collectors can be heavy and installation may require a building permit. The way they work is relatively simple.
