6 Different Types of Thermostat Devices

A thermostat is a common household device used for regulating temperature. There are different types of thermostats in the market, each with its own unique features and attributes. In this post, I am going to examine the 6 types of thermostats, their pro, and cons.

What is the thermostat?

A thermostat is an appliance that controls a home’s temperature by regulating airflow to keep the temperature at an agreeable level. They regulate the temperature by turning the heating and cooling systems on or off.

Here is a brief overview of each type of thermostat:

1) Mechanical Thermostats

Mechanical Thermostats

Mechanical thermostats are the earliest types of thermostats and are not digital, they are usually round with a dial and a needle that points to the current temperature, they use a mercury bulb or a bimetallic coil to sense when to turn on or off the heat or air.

As time has passed, these have been improved because there is no longer any need for the mercury bulb to sense the temperature and there is no need for a bimetallic coil but the dial to be accurate.

Pros of the Mechanical Thermostats

1. They have a fixed reading, there is no need to re-adjust it

2. They have a replaceable bulb

3. They are easy to install

4. They can be used on almost any heat or air system

5. The readings are accurate within 1 degree Fahrenheit

Cons of Mechanical Thermostats

1. They have limited accuracy

2. They can be temperamental during extreme weather changes and when old age sets in

3. They leak when the point where the needle points to is damaged

4. They need to be readjusted periodically if there is a problem (bimetallic thermometers will require only a small adjustment, while mercury thermometers need to be adjusted regularly)

5. They are more delicate than digital thermostats and can be broken easily

Where someone can find Mechanical Thermostats

Mechanical thermostats can be found in any hardware store or home improvement center. They are usually priced between $3-5 dollars each.

However, if you have a burning desire for this type of thermostat there are several different stores that you can purchase them from.

In the home section of your local department store, you will find a wide range of thermostats that you can use in your home to keep it warm or cool at an agreeable level. Many of these will also be mechanical in nature as well.

2) Digital Thermostats

Digital Thermostats

Digital thermometers are also very accurate. The digital thermostats will measure the temperature that they see in a room and then allow you to adjust the temperature of the room according to your liking.

In order for this to be possible, there are several different kinds of wires that go in between the heating or air unit and the thermometer wire.

This is where some people have problems with digital thermostats. For example, if you do not know what type of digital thermostat you are dealing with, you will not be able to know how to properly set it up.

The thermometers that are used in a home can be found in many different types of settings. Many times they are used to keep the A/C or heat at a specific temperature in a business environment.

In order to ensure that your thermostat is functioning properly, it is important that you find one with the most accurate temperature reading.


1. Digital thermostats are accurate, no matter where they are placed in the house

2. They can be hooked up to a computer system and programmed by professionals

3. It is possible to see when there is a problem with your heating or air unit

4. Digital thermostats do not have to be read at all, you will always know the temperature of your home without having to worry about anything else.

5. They are able to be programmed from a remote location, this can be especially convenient for people who work long hours, who live alone and need to run a programmable thermostat, or for those with children who are just learning how to control their own home.


1. They are a little more expensive than other types of thermostats

2. When there is a problem with the wiring in your home, it can create problems for your digital thermostat because it does not contain all of the wires necessary for operating in your home.

3. If you have one that is not programmable, it can become complicated to set up and you will not know what to do if there is a problem or if you want to change anything on the thermostat.

4. There are some people who choose not to use digital thermostats because they believe that getting a new programmable one is too expensive

5. If there is a wiring problem or if the part of your home that is in need of heating or cooling gets too hot, it can become damaged.

Where People Can Obtain Digital Thermostats

Digital thermostats can be found at any home improvement store, building center, or hardware store. They are typically priced between $3-5 dollars each.

In the same way that mechanical thermostats are able to be purchased at any home supply store, digital thermostats can also be purchased from any hardware or department store.

3)Non-Programmable Thermostats

Non-Programmable Thermostats

Non-programmable thermostats are also accurate and fairly inexpensive to purchase. The benefits of using a non-programmable thermostat are that it is able to be used in any part of your home, including the basement.


1. Non-programmable thermostats are widely available for purchase, allowing for an affordable cost for every part of your home.

2. You can change the setting to make it warmer or cooler in rooms without having to worry about a broken heating or cooling unit or wiring that might be damaged (some mechanical thermostats need a professional to install them)

3. A non-programmable thermostat can be linked to your computer so that changes can be made in your home and you will know exactly the temperature of different parts of your house

4. You will never have to worry about the heating or cooling system in your home not working because there is a problem with the wiring, it is programmed and linked to a computer which will allow you to start up your system when it is supposed to

5. Non-programmable thermostats do not need any cabling installed in your home, they will simply plug into a wall socket and can be used immediately.


1. Non-programmable thermostats can be difficult to understand if you do not understand how it works

2. They are not as accurate as other types of thermostats which can be problematic in homes that are too small or in rooms where there is a lot of insulation

3. Due to the fact that you will have no way of knowing at all times what the temperature is in your home, it can sometimes cause problems if you want to turn up the heat or downshift when necessary.

4. You can not make any changes to the thermostat, you will have to rely on professional technicians to make these changes for you.

5. Non-programmable thermostats are typically very expensive, this is why some homeowners choose another type of thermostat over non-programmable ones.

4)Programmable Thermostats

Programmable Thermostats

A programmable thermostat does not need to be large or complicated at all. The benefits of a programmable thermostat include that it allows you to set your heating and cooling system when it is supposed to, you will never have to worry about lighting up a thermostat as it only needs electricity from the wall socket to be used.


1. There is no need to worry about what parts of your home are too hot or too cold, you can set it for a specific room and it will work

2. Programmable thermostats allow you to set it so that your heating and cooling system will be able to turn on at a specific time or day of the week so that it is used the most efficiently
