Central Heating Thermostats: The Various Types Explained

A digital thermostat is a major investment that will affect your home or business’s utility bills for more than a decade. Moreover, one of the most cost-effective and environmentally friendly heating options is an electric reverse cycle split system. Rooftop solar PV systems increase the benefits of electric reverse cycle systems even further.

Keep in mind that the fuel you have on hand and the size of the area you need to warm determine the energy efficiency of a system.


Different Types Explained

Thermostats are wall-mounted control devices. They come in a variety of styles and configurations, depending on the sophistication of your home’s heating system. For the reasons outlined below, newer versions are unquestionably more energy efficient.

Thermostats That Can’t Be Programmed

Using a manual room thermostat, you may manually control the temperature in your home. When the temperature drops below or rises above this predetermined threshold, the thermostat automatically activates or deactivates the heating. Flipping the thermostat’s switch manually can also turn the heating on or off, but it’s not as convenient.

Mercury indications, metal contacts, or digital systems are used to control manual room thermostats.

The bi-metallic strip is the most popular operating method for manual room thermostats. Two metals are bolted together to produce a strip in these devices. These metals are extremely sensitive to the temperature of the environment. But different metals expand at different rates when the temperature rises. This difference causes a little bend in one of the metal strips. This bending trips the electric circuit and turns off the heating.

Conversely, the metal strips come into contact with each other as the temperature drops, resulting in the straightening of the bend. As a result of the straightening, the boiler is able to re-ignite.

Newer kinds of manual room thermostats rely on a digital control system. You can customize the temperature of your home with this smart thermostat. With an electronic temperature gauge, the thermostat is able to accurately track temperature changes in the space.

Temperatures that are higher or lower than the set point trigger the thermostat to turn the heating system off or on.

Government regulations are now phasing out mercury-powered thermostats because of the hazards linked with mercury.


In addition to selecting temperature settings you prefer, a programmable thermostat allows you to define the times when you want to activate these settings. It gives you the ability to control when and how often your heating system is activated, as well as the temperature it maintains.

You can tailor the temperature control to suit your schedule. For example, you might set the control to turn the heating system on just before the business day begins so your office premises will be warm. You can also set temperatures for different days of the week, depending on whether or not people will be at the office.

It is worth noting, however, that increasing the temperature setting on a room heater will not result in faster heating. Changing the heating system will only waste energy. This is because the rate at which a space becomes warm is determined by the system’s design.

Start by setting your programmable thermostat to the lowest temperature you’re comfortable with at the times you want the system to activate the heating. In order to fine-tune your settings, add one-degree increments every day for a few days until you are comfortable.


You can control a wireless digital thermostat remotely from any smartphone, tablet, or computer as long as you have a connection to a WiFi network. This system is more expensive than manual or progammable alternatives.

However, if you’re looking for convenience features that make your life simpler, such as turning on the heat when you’re on your way home or making remote adjustments to a pre-programmed schedule, this system may well be right for you.

An internet-connected smart room thermostat lets you control the temperature of your house from virtually anywhere using a mobile device. For this purpose, you can install an app for a smart thermostat on your smartphone or tablet.

Then when you’re away from home, you can use the app to change the temperature in your home or office. If you like, you may use a web browser or text message to operate the heating system from any location.

Some of the more advanced smart thermostats may even learn your routine and preferences over the course of several days or weeks. Digital thermostats of this sort can anticipate when you’ll return home and change the temperature in the house accordingly.

It is also possible to heat various rooms in your house at different times using a smart thermostat’s zone management capability.

Smart thermostats offer characteristics such as temperature graphs, automatic frost protection, and a boost option for overriding preset settings.


How a Wireless Thermostat Works

Digital devices like wireless thermostats can provide information about the current temperature in their immediate vicinity. They use electronic sensors and communicate with the boiler to ensure that the temperature in your room is exactly what you want it to be.

There are thermostats that can keep the temperature in the room within a one-degree range. For example, you may achieve a better degree of thermal comfort if you set the temperature to 20°C (68°F). Then it can only go as low as 19.4 °C and rise to 20.6 °C.

The boiler will know what to do next if the thermostat detects a dip or rise in the temperature of the room. When you use a smart device to regulate your thermostat, the same thing happens.

Some people think that setting the digital thermostat to a target temperature will maintain your home at a consistent temperature whether you’re home or not. They believe this can save your heating system from having to work as hard. Others repeatedly turn their heaters on and off when they’re away from home to conserve energy.

In fact, however, studies show that it is better to lower your thermostat when you are not home. This will allow the temperature in your house to drop naturally. Then turn the heat back on when you return. However, there are a number of considerations here, including the size of your house and the effectiveness of your insulation.
