Thermostats: Everything You Need To Know

A thermometer reads the temperature of an area; thermostats control the cooling and heating, with both depending on weather conditions. But technology has taken it beyond that.

Is your room temperature rising? Is it decreasing? Any which way, thermostats can read, maintain, and regulate temperatures, while keeping your home at comfort.

One thing about these HVAC systems is, you can never go wrong with them. This, however, takes us to the mechanism involved. What types do they have?

Types of thermostats

While thermostats can take several forms, the types fall into just two categories: mechanical and digital.

Today, digital controls have taken over, although some still prefer mechanical thermostats due to their affordability and easy-to-use switch.

Whether mechanical or digital, you can easily regulate heat in your home, but one's means differ from the other.

Digital thermostats

Digital regulators, otherwise known as smart ones, are scaling when it comes to demand. Mechanical regulating devices aren't left out either.

You don't need to do much with a digital heat controller. All you need to do is program its HVAC system and let it run. Automatically, either boiler-mounted or fixed on a wall, it can easily read a room's temperature by working towards its target.

Take, for instance, if the room's temperature is low. Digital thermostats are programmable and will raise its thermal reading until it meets the set point. And when it does, the degree stays coordinated with maximum comfort.

These instruments can also work with time frames, say, you've studied the weather chart and season for this period. Once you've programmed the device to work with the specific time frame, you won't have to worry about the ventilation of your home.

Mechanical thermostats

Controlling the temperature of your room, workplace, or office with this type of thermostat is also well-achievable. However, in this case, the method of reading differs.

These electricals have two metal parts (coated with a bimetallic strip) to detect the degree of hotness or coldness and an electric circuit in conjunction with your heating system.

As temperature increases, the metals expand. This action triggers the automatically-connected switch to go on and off at the right time.

How to use one

There's a slight difference in the method of use between these two main types of thermostats. Both means work for the same purpose, but a mechanical heat controller expands gradually. By contrast, digital ones are quick to respond.

  • Using digital thermostats is much more comfortable. You probably don't have to monitor the home temperature. Set up the HVAC system by the weather. Leave the rest of the work for these programmable devices.
  • Mechanical regulators use a bimetallic strip to function. Just ensure it is connected to the heating system. Precisely, in hot conditions, one of its pieces expands until the circuit is forced to open. And, in turn, maintaining fresh ventilation. Notwithstanding, these systems have a mechanical dial. Use it to set your desired point and let the bimetallic strips and heating system do the work.

Things to consider

What else do you need to take note of, you might think? Nothing much. Just little precautions for proper use. Make sure you do the following:

  • Fix your thermostat in a well-ventilated room to ensure an appropriate reading of temperature. Avoid placing it behind a curtain or in a position exposed to the sun to aid functions ideally.
  • Start by setting the point to low heat, say, between the range of 18 to 21 degrees, wherever it suits your comfort.


Here's a good suggestion: scout well for suitable thermostats. They vary in forms: some are wireless and battery-powered. Others come with cables, more importantly, advanced features like leaving a part of the room warm and working automatically with weather conditions.
