How Does A Furnace Know The Temperature? Essential Guide

How do furnaces know the temperature?

How do furnaces know the temperature? It’s crucial for them to heat the air correctly and keep our homes comfortable. To understand this, let’s look at furnace systems. They use either gas or electricity. They work by heating and moving air through ducts and vents to every area of the home.

How Does A Furnace Know The Temperature

The following table shows the components and their functions in a furnace system:

ThermostatSignals furnace to start/stop based on the set temperature.
Pilot Light/Electronic IgniterIgnites burners to begin the heating process.
The gas ValveControls gas flow to burners.
BurnersProduce heat when lit.
Heat ExchangerTransfers heat from burners to air.
Blower MotorSends heated air through ducts and vents.
Temperature SensorMonitors air temperature.

The pilot light or electronic igniter starts the heating process by lighting the burners. The heat passes through the heat exchanger, then to the plenum. Temperature sensors like thermocouples or bimetallic coils/strips check the air temperature. When the desired temp is reached, the sensor tells the furnace to turn off the burner.

For optimal performance and durability, gas furnaces should be maintained yearly and electric furnaces every other year. Plus, replace filters and get professional inspections

If only my ex reacted as quickly as a thermostat to changing temps!


To understand how a furnace knows the desired temperature, you need to know about thermostats. With mechanical thermostats and remote sensors being two options, thermostats are vital components of heating systems. In this section, we will delve into the mechanism of thermostats and their role in regulating a furnace’s temperature by exploring two types of thermostats: mechanical thermostats and remote sensors.

Mechanical thermostats

Mechanical thermostats are simple, reliable, and have been around for a while. Although accuracy is not as good as digital models, they are popular due to their durability, affordability, and ease of use. Some even come with anticipators that can adjust before temperature changes happen. For more accurate readings, position your thermostat away from drafts or heat sources.

Who needs a crystal ball when you’ve got remote sensors? Unless your house is haunted, of course!

Remote Sensors

When picking a remote sensor, make sure it’s compatible with your thermostat.

Let’s look at some types of sensors:

  • Wireless temperature sensor: Battery-powered and can be put anywhere.
  • Wired temperature sensor: Plugs into the wall and is more reliable than wireless.
  • Occupancy sensor: Picks up when someone is in the room and adjusts the temperature.

Using multiple sensors can be helpful for accuracy. It accounts for different temperatures in your house and stops hot/cold spots from popping up. Plus, the thermostat isn’t the only complex piece of the furnace system.

Furnace system components

To understand your furnace’s temperature regulation system, let me walk you through the furnace system components, including the combustion chamber and burners, heat exchanger, gas valve, blower motor, pilot light, and flue pipe. I’ll explain how each component plays an important role in the proper functioning of your heating system, ensuring warm air is supplied to your home. Knowing these components is crucial for regular maintenance and safe operation of the furnace.

Combustion chamber

  • Burners: Convert fuel into a fine spray for efficient combustion.
  • Nozzles: Control the flow rate and shape of the fuel spray.
  • Air registers: Supply air for mixing with fuel for optimum combustion efficiency.
  • Plus, refractory materials in the chamber shield from extreme temps and prevent heat loss.

Maintain these components regularly for maximum efficiency.

A dirty or clogged burner or nozzle can really reduce the furnace system efficiency. Cleaning often is key to keep optimal performance.

Nothing beats burners for warming up a room…unless you’re doing stand-up comedy.


They come in different shapes and sizes, depending on the purpose. Their fuel source can be natural gas, propane, or oil, which affects their combustion properties. Its performance is measured by its turndown ratio – how low it can control output compared to the max capacity.

Depending on the design, it makes either a blue flame (complete combustion) or yellow/orange flame (incomplete combustion). The burner’s performance impacts the furnace’s efficiency and lifespan.

It needs regular maintenance to avoid damage from soot, clogged nozzles, and other issues. Older furnaces contain atmospheric burners that release combusted gases into the air, but modern ones use sealed combustion burners that vent gases outside.

Burners have revolutionized not only home heating systems but also industrial processes like metallurgy and glass production. Key figures from Benjamin Thompson to Johannes Gaedicke have made significant contributions to burner technology.

Nothing beats the warmth of a heat exchanger, except maybe a hug from your grandma.

Heat exchanger

The heat exchanger is a crucial part of the furnace. It transfers heat from the combustion chamber to the air, which then warms up the building. It’s made of either stainless steel or aluminized steel and can come in tubular, plate, or fin forms.

Maintaining the heat exchanger is key. If it’s damaged or corroded, dangerous carbon monoxide gas can enter the living spaces. Cleaning and inspections must be done regularly.

So, don’t forget to look after your heat exchanger. Keep it functioning correctly and safely. Don’t let a lack of maintenance put your home or business at risk. Protect your investment today. And remember, it’s not just the gas valve that gets fired up in this furnace system.

Gas valve

The Gas valve is a vital part of a furnace. It controls the flow of gas to the burner and plays an important role in keeping the furnace safe and efficient. Let’s explore its features and functions.

Gas Valve ComponentsDescription
Valve bodyHousing all other sub-components. Made of brass or aluminum.
Solenoid valveOpening and closing gas access to the burner.
The pressure regulatorRegulates gas pressure before injecting it into the solenoid valve.
ThermocoupleSafety feature that senses heat from the pilot light. Generates electricity to keep the gas line open.

Some newer models even have diagnostic features. This helps identify any malfunctions and prevents expensive furnace repairs.

Remember to maintain your gas valve regularly. Malfunctioned furnaces can cause several dangers. Schedule regular tune-ups with your HVAC technician for optimal furnace performance and longevity.

Forget about costly personal trainers. Get a daily workout by changing the furnace filter. Install a blower motor and get going.

Blower motor

The blower motor is an important part of the furnace system. It’s an electric motor that pushes warm air through the ductwork and into each room. To work properly, it needs to be the right size and speed. Plus, modern motors are energy-efficient, which saves energy bills. So, upgrade your old motor and enjoy cost-effective comfort.

Pilot light

The pilot light is a must-have for a furnace system. It’s a tiny flame that gets the fuel burning and starts the heating process. Cleaning is necessary for safety and efficiency. Dust and dirt on the burner block it, leading to bad air and wasted fuel. Plus, a dirty pilot can give off soot, letting carbon monoxide into the house.

If the pilot goes out often, it could show bigger problems. These could include faulty gas valves or thermocouples, which need professional help.

It’s smart to have a carbon monoxide detector in the home when using a furnace. Carbon monoxide is invisible and has no smell, but too much of it can be fatal. Who needs a chimney sweep when you have a flue pipe ready to take out the trash?

Flue pipe

A flue pipe is a must-have for a furnace system. It’s a metal pipe attached to the furnace and goes out through the roof or wall. Its material is stainless steel, to resist corrosion from acidic combustion gases. Its diameter is 6 inches and its length is 10-20 feet depending on the furnace size. Regular inspection of these pipes is important for optimal furnace performance. Install a carbon monoxide detector close to the furnace too, for safety. Temperature sensors in a furnace system aren’t just for comfort – they matter!

Temperature sensors

To understand how your furnace gauges the temperature, let me introduce you to temperature sensors. These tiny components are vital for your heating system to function properly and maintain your desired indoor temperature. In this section, I will discuss five types of temperature sensors – thermocouples, thermistors, infrared sensors, bimetallic strips, and bimetallic coils and their significance in regulating the temperature of your furnace.


A Metal Combination of Iron-Constantan has a Temperature Range of -200°C to 1000°C. Its advantages are durability and being inexpensive. However, its Disadvantages are low accuracy and a limited temperature range.

Alternatively, Nickel-Chromium/Nickel-Aluminum has a Temperature Range of 0°C to 1200°C. Its Advantages include precision, reliability, a wide temperature range, and a rapid response time. Its Disadvantage is sensitivity to oxidation.

An extra attribute of thermocouples is that they do not require an external power source, making them perfect for remote areas or when electricity is not available. Nonetheless, errors in measurements may occur due to incorrect handling or temperature gradients along the wires.

Therefore, it is essential to follow proper grounding techniques and ensure a uniform temperature across the length of the wires, for accurate readings.

Lastly, Thermistors are useful for monitoring when temperatures get too hot.


TypeResistance vs TemperatureApplications
PTCIncreases with TemperatureOverheating Protection, Motor Control, and Battery Protection.
NTCDecreases with TemperatureTemperature control, Air conditioning, and Car engine management.

Thermistors have a special ability – they can detect even small temperature changes. This makes them great for precise temperature measurements. They work over a range of -50°C to 250°C.

To ensure accuracy with thermistors, it’s essential to connect them correctly. Here are a few tips:

  • Use proper insulation materials.
  • Choose the appropriate wire gauge/cross-section area.
  • Avoid soldering close to the sensing element.

This will help you get accurate results from your thermistor-based sensor system. Be careful: infrared sensors can sense temperature without even touching it – like ninjas!

Infrared sensors

Infrared sensors are multi-purpose. They measure temperatures, detect motion, and provide night vision. Plus, they can be used in low-light conditions for military personnel. However, environmental factors like humidity and other atmospheric conditions must be taken into consideration.

Temperature calibration should also be used. To ensure accuracy, keep the sensor’s path clear of obstructions or debris. Additionally, make sure there is no interference near the sensor, as this could affect its readings.

Bimetallic strips

Bimetallic strips have a unique feature. You can adjust their sensitivity by changing the thickness and composition of each metal layer. Thick layers will give less sensitivity while changing the metal proportion changes the temperature range.

It’s interesting to know that bimetallic strips were used as early as 1835! Warren S. Johnson designed a thermostat with them to regulate room temperatures, making modern-day HVAC systems possible.

So why settle for one material when you can have two? Bimetallic coils are an easy way to ensure accurate temperature sensing. Life’s too short to pick just one!

Bimetallic coils

Bimetallic coils have some technical details. The material composition includes two different metals. Thermal sensitivity is variable. The operating range depends on the max and min temperature needed. Response time is slow compared to other sensors. Accuracy is good for broad temperature ranges.

It’s important to calibrate bimetallic coils to make sure they work well. Plus, proper installation and handling are key. For best performance, choose a material combination that offers the desired level of thermal sensitivity. Also, make sure to do calibrations as needed and maintain it well.

Bimetal SwitchUp to 150°CNormally Closed
  • Thermal cutoffs function based on temperature sensitivity. When the threshold is reached, it opens the power circuit. 
  • Thermocouples detect voltage changes due to temperature differences between two metals. These changes turn on or off electrical signals.
  • Bimetal switches are often used in heating equipment. They disconnect power when an excessive temperature rise happens e.g., a coffee maker turning off the heating elements when water reaches boiling point. Not all high-temp limiting devices are designed in standard sizes. Customized limit switches are available from manufacturers. Limit switches may seem small, but they can make a big difference. They’ve saved many lives by avoiding industrial failures.
  • Pressure switches are like hall monitors of the safety device world – keeping everything under control.

Pressure switch

Keeping an eye on pressure changes is key for safety in various scenarios. The pressure switch is a device that can help you do just that. It can turn an electrical circuit on or off depending on variations in fluid pressure. It works by transforming pressure signals into electric ones and is widely employed in hydraulic and pneumatic systems.

Moreover, this switch can safeguard machines and equipment from hazardous conditions, by shutting them down when thresholds are exceeded. This provides protection for the workers as well as maximizes the lifespan of machinery and apparatus through fast reactions to issues.

So, don’t take risks! Get a top-notch pressure switch now, to keep your applications running perfectly and avoid pricey accidents or damages. Flame rollout switch – because sometimes even fire needs to be reminded of safety protocols.

Flame rollout switch

This safety device is designed to stop flames and hazardous gases from escaping. It is known as a Flame Rollout Switch. It is typically installed on HVAC units that produce high temperatures. It will shut down the system if it detects anything outside the designated combustion area.

Gustav Hertz, a German physicist, invented the first Flame Rollout Switch in the mid-1900s. He found flame rod sensors improved gas furnaces’ performance, and safety, and reduced maintenance costs. Since then, Flame Rollout Switches have become essential for modern-day HVAC systems.

The heat exchanger might even have cracks, which would lead to short cycling as a safety measure to prevent carbon monoxide leaks.

Start by replacing the air filter and see if that helps. If not, check the thermostat’s settings. If it’s faulty, you may need to replace it. For any cracks in the heat exchanger, call a licensed HVAC technician.

Don’t let the problem linger. Ignoring frequent cycling could waste energy, put your health at risk, and damage your system. Take action now and make sure your furnace is running smoothly. It’ll be more efficient and reliable.Plus, no more blower fan hum.

The blower fan continuously runs

Ever had your blower fan running all the time? It’s a total nightmare, especially when you’re trying to sleep. A faulty thermostat is usually the culprit – it can’t detect the temperature and switch off the fan. So, you may need to replace it.

A clogged air filter can also be an issue. This forces the furnace to overwork and keeps the fan running. Remember to clean or change the filter regularly. The limit switch could be the problem too – it controls how hot the heat exchanger gets before shutting off. In this case, you’ll need a licensed HVAC technician.

My mate had the same issue and he couldn’t fix it himself. He tried changing the air filter & cleaning up, but nothing worked. So he had to call an expert.

In conclusion, if your blower fan won’t stop, something must be wrong with your heating system. Have a professional examine it, so you won’t have any surprises in cold months. And remember preventive maintenance is key!

Strange odors or noises

Do you smell or hear anything odd coming from your devices? It could be a sign of a bigger issue. Knowing what’s wrong can help you fix it.

  • Odors: Electrical burning, musty, or chemical smells signal danger. That means something inside the device is wrong and needs to be taken care of.
  • Noises: Whirring, clicking, grinding, or buzzing sounds mean the device parts don’t work properly. You should turn it off and call a specialist.
  • Fans: Devices have fans that can give off noise or smell while running. Dust them off often or replace them if needed, to protect other parts.

Plus, figuring out odors and noises can make your home safer. If you wait until the problem is serious, like an electrical fire, it could be too late. So, fixing it sooner is key.

When repairing your device, follow the manufacturer’s instructions. Doing it yourself could void your warranty or create more problems.

Neglecting upfront costs or not budgeting properly can bring about serious results later on. If not handled well, these expenses may lead to missed deadlines or less excellent work. Not worth the risk if you hope for success.

By viewing initial expenses from a long-term perspective and comprehending their importance in terms of potential returns, you can manage any project with assurance, knowing that you made informed decisions about your investment. 

It’s like investing in a retirement plan, but without having to wait until you’re old to see the benefits.

Energy efficiency and long-term savings

Being energy efficient is key for long-term savings. Optimizing usage leads to lower costs. Upgrading appliances and choosing eco-friendly options like LED lights and programmable thermostats make a difference. Smart home technologies can regulate temperature, and lighting, and reduce wasted energy.

Other factors contribute to success too, like proper insulation, maintenance, and air filters. Companies have embraced eco-friendliness to save money and help the environment. Investing in energy efficiency pays off financially and environmentally.

Replacement costs

When it comes to the repair/replacement of equipment or property, costs are a major factor. Costs vary depending on the quality and type of equipment. Cheaper equipment can need replacing more than pricier options.

Labor and expertise needed for installation also add to costs. The age and condition of the equipment decide if a full replacement or just part replacements are needed. The location also affects the cost.

It’s smart to plan for future maintenance costs when deciding to repair or replace. Investing in quality equipment that requires fewer replacements can save money in the long run. Experienced professionals for installations can also ensure the proper functioning and long life. By doing so, replacement costs can be kept in check. Maintaining costs is tricky – but keeping your sanity is the easy part!

Maintenance costs

Proper maintenance is key to prolonging the lifespan of your assets. To ensure optimal functioning and reduce the risk of costly repairs, every business should start developing a solid maintenance plan from day one. This plan should consider each unit’s specific requirements. Costs may include inspections, cleaning, testing, replacing consumables, and major overhauls. Neglecting these tasks can have dire consequences, compromising safety standards and leading to production breakdowns.

Environmental factors can also affect equipment functionality. Unexpected weather changes, for instance, can cause significant damage if left unchecked- resulting in additional costs. Paying attention to such factors plays an important role in controlling maintenance expenses.

According to “Fiix Software,” 80% of expenditures are on reactive or unplanned repair and maintenance activities that could have been avoided. It’s vital to prepare for the unexpected, by having scheduled inspection protocols in place and noting daily occurrences. 


When the weather gets colder, the furnace takes over. It needs parts like heat exchangers, burners, blower fans, gas valves, and safety devices to work properly. The thermostat reads the indoor temp and signals the furnace. The temp sensor then starts the burners. They heat up the heat exchanger by using natural gas or oil. The blower fan pushes hot air into the house through ducts. To keep furnaces efficient, clean the air filter regularly. Electric and gas furnaces need to be checked by an HVAC technician. For saving energy costs, switch to newer, high-efficiency models. They use less energy but produce more heat. Get a quality filter and get professional installation services. Evaluating the cost factors of your furnace system, such as its upfront cost, energy efficiency, and maintenance and replacement costs, is a smart step to take for any homeowner.
