What type of heater is most energy efficient?

Author: Amy Padberg  |  Last update: Thursday, July 2, 2026

1. Infrared Heaters. Infrared electric heaters heat things and people directly rather than the air around them, which results in significant energy savings. This approach to localized heating minimizes heat loss and guarantees immediate warmth.

What type of heater uses the least electricity?

Oil-filled heaters can be very energy efficient, especially for long-term use. Once the oil is heated, these heaters can continue to provide warmth even after being turned off, using less electricity overall.

What is the most energy-efficient heater style?

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 is the best type of heater for energy efficiency?

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.

What is the cheapest way to heat a room with electricity?

Far Infrared Heaters are the most efficient of all the space heater options and consume the lowest wattage, making them the cheapest to run. Far Infrared is radiant heating and is most easily absorbed by people's skin. In fact, all objects, including us emit and absorb infrared.

The Most Efficient Type of Space Heater

Are oil column heaters expensive to run?

According to Home Inspection Insider, running a 1,500-watt oil heater costs an average rate of 10 cents an hour. If you run your heater for eight hours a day, it would cost you around $25 a month.

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

Example (you can use an electric heater running cost calculator below for different wattages/kWh prices): If we assume the price of electricity is $0.1319 per kWh, a 1,500-watt electric space heater will cost; $0.20 to run per hour. $4.80 to run per 24 hours (day). $11.20 to run per week (8h/day).

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.

Do ceramic heaters use a lot of electricity?

Energy-Saving Features

Space heaters tend to use a lot of electricity and energy only to heat up a small portion of space. However, ceramic heaters tend to be the most energy-efficient option among different types of heaters.

Are ceramic heaters better than infrared heaters?

Quartz infrared heaters offer very fast heat-up and cool down times. Ceramic heaters, however, require more time to heat circulating air and warm up the room via convection. Quartz heaters can be used to create quieter heating equipment as in most cases air movement from noisy convection blowers is not needed.

What is the least harmful heater?

Sealed combustion heaters are much safer to operate than other types of space heaters, and operate more efficiently because they do not draw in the heated air from the room and exhaust it to the outdoors. They are also less likely to backdraft and adversely affect indoor air quality.

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 heater does not use a lot of electricity?

Ceramic and convector heaters take a little longer to get up to temperature but can heat larger spaces and most often have an adjustable thermostat to help you manage costs. Wall panel heaters also fall under this umbrella. Their low wattage means they use less energy, but they also take longer to warm a room.

Are infrared heaters expensive to run?

But don't worry, infrared heaters are incredibly efficient. They're designed to keep a space warm while using as little electricity as possible. This makes them much cheaper to run than central heating, space heating, and air source heat pumps.

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.

What are the disadvantages of oil filled room heaters?

Disadvantages of Oil Heaters
  • Slow Heat Production: Oil room heaters gradually produce heat in comparison to electric heaters that instantly warm up a room. ...
  • Heavy Mechanism: Oil-filled room heaters are bulky in comparison to electric room heaters.

Do oil-filled heaters need to be refilled?

Once the area or room reaches a comfortable temperature, oil-filled heaters will automatically cycle on and off to maintain that warmth, instead of running continuously, saving you money while preventing overheated rooms. Oil never needs replenishing. The oil isn't used as fuel, so there's no need to replace it, ever.

Is it cheaper to turn up the heat or use a space heater?

Using a space heater can be a good way to boost the temperature in a small, drafty room—and it could be less expensive than cranking up your central heating system. But a space heater is economical only if you use it judiciously.

How big of a room will a 1500-watt heater heat?

In other words, a 1,500-watt heater will be great for a 250-square-foot room with central heat. If that same room had no other source of heat, you'd need a 2,000-watt heater.

What is the difference between a 1000W and 1500W heater?

1000 watts should warm up large bathrooms, small living rooms, or a small room. 1500 watts will heat spaces up to about 150 square feet and can help you stay warm and toasty in a medium-sized room, office, kitchen, or modest-sized living room.

Are oil heaters safe to leave on overnight?

Oil-filled heaters are very less likely to cause you any trouble when you leave them on overnight. These radiators have a high boiling point which helps the internal pressure of the oil stays constant. They don't have any moving parts, so you won't have to face any type of noise and sleep interruption.

Which is better, an oil heater or an electric heater?

The hot oil heats the fins, which in turn radiates heat into the surrounding air. Unlike an electric radiator, which heats up quickly and provides instant heat, an oil filled radiator takes longer to heat up but retains heat for longer periods, making it more energy efficient.
