Know What Lies Beneath: The Mechanisms Within Your Household

Maintaining an entire household on your own is hard work. Most households are multi-faceted. There’s the financial aspect that includes the main sources of income, the social aspect which involves the members of the family, and the technical aspect that involves the house itself.

You might be able to balance your work and family life with no problem, but adding a third factor into the equation can be overwhelming. This is especially true when all the household responsibilities fall on your shoulders, and you have no other choice but to deal with it.

The mere idea of running a household all by yourself can be daunting, but not when you get a deeper understanding of how the individual aspects of your house function. Knowing the mechanisms behind your household items and utilities will allow you to contact the right experts to repair them when they break.

If you think about it, all the appliances and utilities in your home are designed to perform their function when an action triggers them. This mechanism is called control instrumentation, and it can create reactions based on measurements such as pressure, temperature, current, voltage, or flow.

The mechanism may sound very technical or scientific, but it can be commonly found in most of what you can see inside your home. You might be surprised to find out how often the mechanism is used to make your everyday routines possible. See it for yourself in these four examples:


Most homes have built-in thermostats that the owners can use to control the temperature. It’s a vital component of the household because it can keep the house cool in summer or warm in winter. People learn how to operate the thermostat easily because it’s adjustable, but do they know how it really works?

All thermostats have electronic sensors that can measure the internal temperature of a certain place. This makes it possible for the thermostat to “read” the current air temperature and match it with the target temperature that you have set for your home.

If the room and target temperatures don’t match, the thermostat will send a signal either to the furnace or the air conditioning system. This makes it possible for your thermostat to control the temperature of the room with a simple switch on the wall.

Bread Toasters


One of the most used appliances for breakfast is the bread toaster. All a person has to do when they want toasted bread is to insert two individual slices into the openings, push down a button that sends the bread inside, and wait for the golden-brown bread to come back up.

Toasters are designed with different settings that can give you varying outcomes. The manufacturers of bread toasters carefully calibrate the device’s internal rack to pop up when it reaches a certain temperature for a determined amount of time, which is why it “knows” when the bread is done.

It’s a simple device that people always use but rarely discover how it actually works. Knowing that there are heating coils within the toaster that can sense the device’s internal temperature will allow you to pinpoint the problem in case it ever stops working.


Using the toilet is part of everyday life. In fact, people spend an average of one hour and 20 minutes on the toiler per week. But in all that time they spend on the toilet, one would think that they are at least curious about how the toilet works.

The beauty of automatic flushes is that you don’t even have to bother about how the toilet works. The most important thing is that it does, and at the slightest malfunction, you can always call a plumber to make sure it works again.

Most toilet problems are actually easy to resolve if you know how it works. For instance, for the flushing mechanism to work, the toilet needs to have a filled water tank that never overflows. This is because it has a floating device that closes a valve, which acts as a sensor that sends signals to the pipes that the tank has enough water inside the container.

Circuit Breakers

It’s normal for a household to use multiple appliances plugged into outlets all at the same time. But do you ever wonder just how much electricity is too much for the circuits before they break? Most of the time, you don’t even have to wonder because the circuit breaker does the work for you.

To avoid accidental fires in the house caused by a short circuit or an overloaded electrical system, the circuit breaker trips the electricity to the entire house. Circuit breakers are automatic switches that are designed to protect the electrical circuit inside your house.

The reason why you’re experiencing sudden power outages can be because your circuits are overworked. It can be an indication that a potentially dangerous situation involving your appliances might have happened, but luckily, the circuit breaker “sensed” the fault before it even happened.

At the surface level, everything can be overwhelming. But taking the time to understand how things, devices, and utilities actually work will give you a better grasp of the situation. So before you let your fear take over during overwhelming situations, you should know that you can learn how to resolve them appropriately.
