Different Kinds Of Heaters And Their Economic Value

By Alex D White


What comes to your mind when you hear the term heater? Well it could be anything, right. There are various types of heaters, which differ in the way they work, their size, purpose and in many other aspects. Selecting a heater will greatly depend on the various types of heaters available that you happen to know.

You have heard of the electric water heaters, which basically are made of a piece of wire with a high resistance that heats water when they heat although they should not come into direct contact. They use silica to make them safe from risks of electric shocks. You need to upgrade to a more energy efficient like a solar water heater type in case you have a low quality one that breaks down in the middle of a hot shower.

Electric heaters or electric stove heaters use electricity to provide heat. They turn electricity straight into heat via a resistance aspect in the metals involved. Heat distribution will however change from heater to heater. They are fairly priced and economical because of the convection heat they produce.

Some heaters such as the convection heaters will heat up the air and finally heating the entire house through conduction of the heat. Infrared heaters alternatively heat objects inside a room directly instead of the air. Heat pumps are a kind of heaters that suck heat from outdoors and transfer it to the inside.

Convection heaters get their power from a resistor which opposes the flow of electricity. The electricity energy turns into heat and as it flows through the metal heating element. Convection heaters heat air above them and as it rises up, it spreads out into the room. There are forced air convection heaters which heat air through blowing air over some heated coil using a fan. The air spreads out into the room and eventually heating up the room.

Another type of heaters is the radiative heaters that use elements of much higher temperatures than the convection heaters. These heating elements are enclosed in a protective covering such as quartz that prevents heat from escaping. This keeps the heating element extremely hot. They are better in heating objects as compared to heating of air. They are used to heat the body directly by staying close to them. They are cheap and ideal when used in areas that require short duration of heat like bathrooms.

There are also heat pumps that use a pump to drive a liquid through two sets of coils. This liquid is called a refrigerant. It flows through a condenser coil inside the house, where most of the heat is transferred into the air. This in event warms the room and cools the refrigerant at the same time.

The refrigerant gets decompressed in the evaporator coil outside the house. Heat on the outside warms up the refrigerant again and it flows back to a compressor. This cycle of taking air from the outside and pumping it to the inside continues until the house gets heated. They are cheap, efficient and provide both heating and cooling.
