Types of Heaters

Currently, there are 5 main types of heaters that have their standout features that you can consider:

Infrared heater

Infrared heaters work by generating electromagnetic waves to increase the temperature of surrounding objects. It resembles the thermal effect of the sun on the Earth.

Dr. The Infrared DR-968 is the best overall infrared heater product when using electricity as the primary power source. It is with a fan, so distributing heat throughout the room space will be faster than the type without.

Fireplace Heaters

Fireplace Heaters are products that require electricity to operate. However, they do have a stand-alone fireplace and a flickering fire with lots of logs. Even after turning it off, they still retain a certain amount of heat.

Oil Filled Heaters

The principle is to heat it with electricity and transport that heat the inside of the heater in columns. Next, they spread throughout the room, increasing the temperature.

Oil Filled products and infrared heaters do not come with a fan because they are perfect to heat the air. At the same time, they can also be moved between rooms or used for large rooms.

Panel Heaters

Panel Heaters are used for rooms with a small area and use electricity to generate energy for the internal heating element and have a slim design that should be near the user. Although Panel Heaters help save space quite well when they can be hung on the wall, they are not portable.


The size of the device will largely depend on the size of your room. The current suppliers all produce electric ones in the home of various sizes and are pretty compact.

It would help if you chose a heater that can spread heat evenly throughout the room and is suitable for the space.

Ease of Setup

Electric versions that are easy to install will allow you to connect the electricity and turn it on in no time. 

In addition, they will likely have a connection to WiFi and will take a long time to turn on. However, Heat Storm HS-1000-WX-WIFI Infrared will have more utility than devices without this feature.

Temperature Controls

Some allow you to adjust the heat level when equipped with different controls. If you are looking for the best indoor electric one for large rooms, you need to consider whether you want the unit to operate at the correct temperature or need a knob to know the heat level.

Safety Features

The current safety feature of most electric home devices is automatic shut-off, turning the unit off if there is a problem and overheating protection, or turning it off if the temperature reaches a dangerously high level.


If you often have problems forgetting to turn off the heater, you should choose an indoor electric heater with a timer, and your worries will disappear. All you need to do is set the time and start the device; it will end when the time is up.

It would help if you considered the De'Longhi DeLonghi TRD40615E as it offers a 24-hour Programmable Timer to turn the unit on and off.


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

If you have an electric heater in your home with 1500 watts, it can heat a space to about 150 square feet or 10 inches by 15 inches. At the same time, the ability to work and keep warm corresponds to a medium-sized room.

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

The cost you need to operate a 1500 watt heater will depend on your time of use in a day, capacity, heat settings, and electricity price.

You can calculate the cost for a day of using a 1500w electric heater by the following formula:

  • The amount of electricity consumed equals the wattage (watts) of the device times the number of hours you plan to use per day: Device power consumption = Power x Usage time.
  • The electricity bill equals the amount of electricity consumed x the unit price of electricity. The supplier on your invoice will quote the unit price.
  • Divide the answer by 1,000 to answer your question about the cost of your heater.

How can I heat my room cheaply?

Electricity bills are always a big deal when using them, especially with large spaces. Here's what you can do to keep costs down:

  • Use insulation curtains
  • Use a heating blanket.
  • Use carpet for the floor.
  • Block the door to prevent cold air
  • Hanging A Rack On A Radiator.

Alternatively, you can consider affordable and affordable heaters like the AmazonBasics Portable Eco-Smart. Yet, its quality is stable and does its job well.

Are electric heaters safe to leave on overnight?

You can use heaters with fixed radiators for overnight use, but they present risks if left unattended due to spillage.

You should choose a device that automatically turns off and works long enough to warm the room.

Is it cheaper to run an indoor electric heater or central heat?

Using indoor electricity like the Duraflame DFI-5010 Fireplace Heater requires less power and feels more like a flame than central heat. 

At the same time, the heater will be more efficient in terms of temperature and the ability to warm up quickly.
