The working of a heat furnace

Category: Business & Finance 3 0

Summers might be around the corner, but there is still some time for winters to go. So while we are going through it, some of the curious minded people might want to learn about how furnaces work, and how do furnace repair service repair these devices.

If you search the internet, you will come across plenty of useless information. Either the stuff on the internet is too detailed, or just downright vague. So, to help the laymen out, today we are writing this blog with the main intention of teaching you about the working of a heat furnace.

So, without wasting anymore time, let us get right into it.

What are Heat Furnaces?

Heat Furnaces are devices that extract heat from the cold surroundings and then eject the heat into the high heat environment (indoors). While this might sound counterintuitive, it is based on the second law of thermodynamics.

The second law of thermodynamics tells us that to transfer heat from a cold environment to a hot environment, some amount of work must go into the system. So, in the case of furnaces, the furnace is taking work (in the form of electrical energy that we give it).

It is using this work to transfer the energy inside your house, to keep the house warm. This is the scientific working of a heat furnace, on its most basic level. Of course, on the higher level, a large number of complexities may also come into play.

For instance, the efficiency of a heat furnace depends on the amount of heat that it has ejected into the hot environment (indoors) and on the amount of work that it has used up in this process. The higher the efficiency, the lower your utility costs will be.

So, when you are buying heat furnaces, always go for the higher end options that have a high energy efficiency. This is the only way to save costs in the long run, even though it might require a higher short-term capital.

Basic components of heat furnaces

Now, let us look at some of the most basic components of heat furnaces. Simply put, a heat furnace consists of the following main components:

Gas valve and thermostat

First of all, we have the gas valve and thermostat. The furnace begins by receiving some signals, based on which it decides to trip or to heat the indoors. These signals come from thermostats that are installed onto the furnace.

The thermostat function on temperature limits that you have set and prevent the heat pump from heating your house too much or from letting it get too cold.

Heat exchanger

The heat exchanger is the component of your heat furnace that primarily exchanges heat with the surroundings (with the help of a working fluid) and ejects this heat indoors. Without the heat exchanger, a heat furnace would simply not work.

To have a good furnace, it is important to have a higher quality heat exchanger installed. This is the one quality that you will find in all high-end heat exchanger.

Blower motors and fans

These are also incredibly important as they are used to transfer the working fluids between the pipes. At the same time, the blowers are used to move the heat inside the environment. In this process, convection heat transfer takes place majorly.

Often when your heat furnace is not working, there is a problem with one of the above-mentioned components. And these are also the first three components that furnace services Long Beach also check. If they are working fine, then they move on to the internal parts of the heat furnace.
