Can You Do Anything About a Thermostat That Keeps Getting Too Hot?

How do you keep your house at a comfortable temperature? There are several modern alternatives to the traditional temperature dial, such as digital displays and mobile devices. In essence, they are all just various thermostats. Collectively, the controls for a heating system are known as the radiator thermostat. The thermostat can be used to keep a room or a boiler at a predetermined temperature. When the temperature inside the house drops below the thermostat’s set point, the heating system kicks on automatically. When it senses that the interior has achieved the set temperature, the thermostat will shut off the heat.

The following supplementary features and customization options have been built into this framework:

  • For some thermostats, neither wiring nor batteries are necessary.
  • The boiler has direct physical connections to other components.
  • If you have a programmable thermostat, you can set the heating system to turn on and off at specific times.
  • When a change in your routine is detected, a smart thermostat may make the appropriate adjustments automatically.

Just How Many Distinct Thermostat Types Are There?

Many different types of thermostats are available to meet the needs of different homes and individuals. Digital and mechanical thermostats are the two most common types. There are a number of key distinctions between the two. As a result, electronic or digital thermostats are becoming the norm rather than the exception. The core components of digital thermostats make them quick to react to changes in indoor temperature and highly accurate. A network of electronic sensors keeps tabs on the inside temperature, sending that data to the radiator thermostat so it can make minute adjustments to keep the temperature within an exact degree of where it needs to be.

In contrast, the temperature is controlled by the movement of two metal plates in a mechanical thermostat. Together, they form a bimetallic strip that is used in the thermostat’s sensor. Electronic circuits can be programmed to regulate a home’s heating system by sensing the thermal expansion and contraction of individual metals. The radiator thermostat takes this information into account and adjusts as needed. A bimetal thermostat can be off by as much as five degrees from the desired temperature, so keep that in mind. Mechanical thermostats, on the other hand, are popular due to their inexpensive cost and ease of use.

How a Smart Thermostat Works: An Explanation

Thermostats are installed in buildings and used to regulate the inside climate by indicating when the HVAC system should kick on. In the older, analog thermostats, the lever is used to rotate a coil, which in turn triggers a mercury switch. Mercury acts as a conductive material, so when it’s present in a furnace, it activates a relay that runs the heat source and the exhaust fan. The mercury sensor in the thermometer will tip back when the room temperature reaches a predetermined level, disconnecting the circuit and shutting off the heater.

All digital thermostats today are electronic devices that use a thermistor to determine the surrounding temperature. Thermistors are temperature-sensing electrical resistors. A digital thermostat’s internal microcontroller reads the unit’s resistance to determine the room’s actual temperature.

Digital thermostats are more flexible than traditional models since they may be programmed at any time. Some common schedules include heating the home for two hours while everyone gets ready for the day, four hours when everybody is home in the evening, and eight hours when everybody is asleep in the early morning. It may be possible to save monthly energy expenditures by not keeping the heating at a comfortable level while no one is around.

Digital thermostats with WiFi connectivity are known as “smart thermostats” and allow for remote temperature regulation. The thermostat’s temperature can be changed from anywhere in the world by downloading the manufacturer’s app. The information, such as the desired temperature and fan speed, is sent to the smart radiator thermostat via the mobile app, and the thermostat then send signals to the HVAC system to engage the appropriate components. Connecting a smart thermostat to a smart speaker enables you to set a schedule and make temperature adjustments with just the sound of your voice.

How Often Should a Thermostat Be Changed?

Thermostat replacements should be arranged to coincide with HVAC system upgrades wherever possible. For this reason, a new thermostat needs to be installed at the same time that the HVAC system is upgraded. So even if you upgrade your system with parts that are out of your thermostat’s range of control, you won’t have to replace it.


Much like when you upgrade your TV or computer, your radiator thermostat will eventually need to be replaced. Thermostats break down from age and wear in the same manner that older HVAC systems do. When the thermostat’s capacity to make accurate temperature determinations is compromised, its efficiency declines. The “dead zone” of a thermostat, the range of temperatures outside which the device stops working, grows over time. These problems are extremely inconvenient and may lead to higher monthly heating and cooling costs. Changing out a worn-out thermostat is a cost-effective measure you can take to extend the life of your home’s heating system.
