How Does a Pellet Stove Thermostat Work?

It is quite evident that pellet stoves are perfectly designed for controlling room temperatures. They do so by using the thermostat that configures temperature control. 

Pellet stoves operate efficiently using a simple process. A thermostat is connected to the stove to determine the desired temperature. With a wide range of temperature controls, you can adjust the temperature on the control board. Once set, the unit will then operate at the selected heat range setting. Consequently, the stove will continue to operate until the desired room temperature is met.

When is it Time to Replace My Pellet Stove Thermostat?

The lifespan of a pellet stove thermostat cannot be specified. However, a decent quality unit can serve you effectively for approximately ten years. After a decade of operation, the unit might malfunction due to dust accumulation or aging wiring. A faulty thermostat will show signs like abrupt temperature changes, inaccurate readings, or even coolant leaks. When you come across these, you know it is time to change the thermostat. 

Can Any Thermostat Be Used On a Pellet Stove?

Not all thermostats can be used on a stove. Some stoves come pre-packaged with a thermostat to control the temperature. They are not only compatible with the unit, but they also are easy to use.

However, some models don't come with a thermostat and require you to purchase one separately. As a result, you might face compatibility issues.

Some pellet stoves feature multiple-stage heating that requires specific thermostats to operate effectively. Pairing such models with a conventional thermostat can cause malfunction, or they might not function at all.

Therefore, you must purchase the right type of thermostat for your device. You can figure out the compatibility by either checking the manual that comes with the stove or ask the seller at the time of purchase.

Types of Thermostats For a Pellet Stove

You can pair different types of thermostats with your pellet stove, provided they are compatible with each other. There are various thermostats available that can work effectively with your model. Some common types include:

Non-programmable Thermostats

Non-programmable units are one of the most basic ones that you can pair with your pellet stove. These units lack programmable nature. Instead, they use manual controls to effectively adjust the desired room temperatures.

With just a few button presses, you can easily control and monitor your room temperature. The simplicity and energy-efficient operation are the two areas where these units perform well. 

Lux T101141SA

Programmable Thermostats

Unlike non-programmable models, these units can be programmed efficiently. They either come pre-programmed from the manufacturer, or you can program them yourself, according to your needs. 

Programmable units work great if you want temperatures to adjust automatically during the day or night. If you are living in an area with sudden temperature changes, then programmable units are the perfect option.

Wi-Fi Thermostat

Wi-Fi thermostats feature wireless connectivity that allows you to remotely control your device. They operate efficiently using a remote or app that features all the controls you require to control room temperature. These units are high in demand due to their ease of use and convenience.

Pros of a Remote Thermostat With a Pellet Stove

Investing in a quality thermostat will always benefit you in the long run. To ensure the reliable quality and performance of your stove, you must buy a quality device. Here’s why doing so is beneficial:

Consistent Performance

With a quality remote thermostat, you can enjoy reliable performance. Temperature control would be quite effective and consistent over the period. A quality unit will provide you with highly accurate information and further enhance your experience.

Ease of Use

The best part about using a remotely controllable unit is the convenience it provides. Rather than controlling room temperatures manually by getting up and adjusting the settings yourself, you can do it remotely from a distance away from the stove. It is not only more convenient but also quite simple and easy.

Increased Lifespan

There is no doubt that quality units tend to last longer. If you own a high-quality thermostat, you might benefit from it quite longer than you expect. Remote thermostats are technically advanced, and therefore are equipped with better components and build quality. With proper maintenance checks, a good device can serve you for more than a decade!

How to Hook up a Thermostat to a Pellet Stove

Installing a thermostat to a pellet stove is quite simple and easy. However, there is some sort of knowledge and understanding of the unit required to successfully perform the installation.

To ensure you do it properly, we have listed a step-by-step process:

  1. First, unplug and power off your unit.

  2. Remove the screws from the exhaust outlet cover using a wrench.

  3. Now, loosen the screws that hold the back panel in place. Don't forget to remove the strain relief for the power cord.

  4. Once the screws are removed, you can easily remove the back panel out of its slot.

  5. Locate the thermostat connect block found on the rear of the control board. You can find a small wire jumper that is pre-installed from the factory.

  6. Remove the jumper using the screwdriver and insert the thermostat wires in place of the jumper.

  7. Tighten the screws back once the wires are connected to the respective terminals. Note that it doesn't matter which wire goes in either terminal.

  8. Reinstall the back panel and set up the thermostat by following the product's manual instructions.

  9. The control board will automatically read the thermostat and will be ready for operation.

If you are still uncertain about the process, refer to the video below for a detailed demonstration.

Installing a thermostat to your pellet stove is worth the money if you want a controlled climate inside of your home. These units not only allow you a convenient use but also perform effectively for a long time.
