Electrical Energy To Heat Energy

Electrical energy is converted to heat energy through an electric heating process.

Electric heater converts electric current into heat. Every electric heater is made up of electrical resistor and the electric current passing through a resistor will convert that electrical energy into heat energy.

Types of electric space heating

  • Radiant heaters
  • Convection heaters
  • Fan heaters
  • Storage heating
  • Domestic electrical underfloor heating

How to make a simple room heater at home step by step video?

In this project how can implement room heater in a simple step by step manners with the materials available at home easily

First, take one high voltage electric bulb with two red connected wires. Now take a pair of red electric wire and connect it to one electric bulb and use the other end of this wire and connect it to the second high voltage electric bulb.

Make sure you wind the open end of the red wire with insulating tape to avoid any hazard.

Take an empty cardboard box and on one side create a circular hole as shown in the video.

Next, take a small piece of rectangular shape wooden piece and stick to the lower center on the circle of the box with the help of hot glue and attach a DC motor to it.

Now attach a small fan to the front of DC motor, place the two high voltage bulbs into the box. Connect the red wire from the electric bulb to the electric switch box and turn it on.

Next, connect wires from DC motor to a 9V battery. You will observe that the small fan connected to the shaft of the DC motor will start to rotate and will create heat in the room.

Questions & Answers

1. Which type of room heater is good for health?

Oil-filled room heaters are good for health.

2. What is an electric room heater?

An electric room heater is a convenient appliance that provides focused and localized heat for people that are elderly, ill or with limited mobility.

3. Is room heater good for health?

No, it burns oxygen and reduces humidity in the air. Burning of oxygen leads to a potential decrease in oxygen levels which results in suffocation.
