Kinds Of Heaters As Well As Their Effectiveness

By Alex D White


What usually crosses your mind whenever someone mentions heaters? Well, it may be anything depending on what you are used to. Different kinds of heaters exist each of which function differently. Your choice of heater will greatly rely on the various heaters that you already know.

You have heard about the electric water heaters, which essentially are constructed with a bit of wire rich in resistance. It warms water through contact although the wires should not get into direct contact. Silica is used to ensure they are safer from perils of electric shocks. You have to upgrade to some more energy-efficient such as the solar heaters if your electric heater is not working well since these can save you a lot of money on electricity bills.

Electric heaters or electric stove heaters use electricity to give out heat. They turn electric energy directly into heat through a resistance element in the metals involved. Heat distribution will however vary from heater to heater. They are fairly safe to use and cheap due to the convection heat that they give off.

Convection heaters heat the air around them then it spreads out to the rest of the room and heats the room in that process. Infrared heaters work by heating objects directly instead of the air while heat pumps work by removing warm air from the outside and taking to a cold inside and vice-versa.

Convection heaters are a kind of heaters operated by a resistor that opposes the flow of electricity. The electrical energy turns into heat so that as it flows within the metal, it heats it up. Convection heaters heat air above them directly, the air moves up and spreads out into the room. Some heaters such as the forced air convection heaters heat air by coming into contact with the heated coil. This air spreads out into the room and this way the whole room will get heated.

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.

You will also find heat pumps that use a pump in driving a liquid through two coils. This liquid is known as a refrigerant. It flows via a condenser coil indoors, where the majority of the heat is moved in to the air. This in event warms up the area and cools the refrigerant simultaneously.

The refrigerant will get decompressed within the evaporator coil outside the house. Heat from the outside warms the refrigerant again and again it flows to the compressor. This cycle of taking air inside from outdoors and moving it inside continues until the whole house gets heated. They are cheap, efficient and do both cooling and heating of the house.
