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.

There is the electric heater or the electric stove heater; they convert electric energy to heat. The resistance element is the metals involved. The way heat will be distributed will depend on the model of the heater. Electric heaters are fairly safe to use and they do not cost much as well as their maintenance cost is low.

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 are a type of heaters powered by a resistor that opposes the flow of electricity. The electric energy turns into heat and then it flows through the metal heating element. Convection heaters heat energy above them directly, the air rises and spreads out into the room. Some heaters such as the forced air convection heaters usually heat air through blowing air over heated coil using a fan. This air spreads out into the room and in the process the room gets heated up.

Radiative heaters are another type of heaters that use high temperature elements as compared to convection heaters. They are cheaper and economical. These elements are encased in a protective covering which prevent the heat from escaping. This keeps the heating elements very hot. They are ideal for heating objects directly as compared to heating of air. They are ideal for heating places which require short durations of time such as instant bathroom water heaters.

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.
