What is the hysteresis of a pellet boiler?

Choosing the right hysteresis for your pellet boiler is one of the key settings. Read the following guide and make your boiler run efficiently and economically regardless of the conditions outside the window.

What is the hysteresis of a pellet boiler?

Pellet boiler hysteresis is a mechanism that ensures stable operation of the heating system by setting the temperature range at which the boiler turns on and off. With the two-way hysteresis on Stalmark boilers, the user sets both the lower and upper temperature thresholds, allowing more flexible management of the boiler cycle.

For example, with a set target temperature of 60°C and a hysteresis of 5°C, the boiler will turn off when it reaches 60°C, but will only turn on when the temperature drops to 55°C. Thanks to the two-way hysteresis, when the temperature starts to rise and exceeds the set upper threshold (e.g. 62°C), the system can automatically adjust the intensity of operation or stop heating before responding to the drop below the lower threshold.

Introducing such functionality helps minimize the number of cycles of turning the boiler on and off, which reduces wear and tear on the unit and increases its lifespan. For the user, this means more stable and efficient operation of the heating system and optimal fuel consumption, which translates into energy savings and better control over thermal comfort.

What should be the hysteresis of a pellet boiler?

Now that you know what hysteresis is, it's time to answer the question: what should be the appropriate hysteresis of a pellet boiler at home? The optimal value of this parameter depends on several factors, such as:

- boiler power

- the area to be heated

- external conditions (e.g. outdoor temperature)

- user expectations for thermal comfort

Typically, the optimal hysteresis for a pellet boiler is between 3°C and 7°C. A smaller hysteresis (e.g. 2-3°C) will cause the boiler to turn on more often, which can increase fuel consumption and strain the boiler mechanisms. A larger hysteresis (5-7°C) allows the boiler to turn on less often, which in turn can reduce operating costs, but also make the indoor temperature less stable.

How to set the hysteresis of a pellet boiler?

Most pellet boilers have a built-in control system that allows you to adjust this parameter. The procedure for setting the hysteresis depends on the boiler model, but in general it looks like this:

1. Enter the control menu - in most cases, you will access the boiler settings through the control panel or mobile app (if the boiler is compatible with a remote control system).

2. Select the temperature option - in the settings you will find a section for the temperature of water in the heating system and the hysteresis.

3. Hysteresis adjustment - set the hysteresis value at the level that is optimal for you. It is best to start with a value of about 5°C and test how the system works in practice. You can adjust the setting depending on whether the boiler turns on too often or the thermal comfort is not sufficient.

Optimal hysteresis of a pellet boiler - what to pay attention to?

Setting the optimal hysteresis of a pellet boiler requires a little patience and observation. Here are some key things you should pay close attention to:

- Pellet consumption - if you notice that the boiler is using more fuel than usual, perhaps the hysteresis is set too low. Try increasing the hysteresis by 1-2°C and see if the pellet consumption decreases.

- Thermal comfort - it is important to look not only at the bills, but also at the thermal comfort in the house. If the room temperature fluctuates too much, it may mean that the hysteresis is set too high. In this case, lowering this parameter by 1-2°C is likely to improve the stability of the heating.

- Frequency of turning on the boiler - turning on the boiler too often can lead to faster wear of the device. On the other hand, too low a hysteresis can cause the device to operate in an almost continuous mode, which is beneficial neither for the boiler nor for your wallet.

Setting the right hysteresis for your pellet boiler is a key element that affects the efficiency of your heating system. By understanding what the boiler hysteresis is and how it works, you can better control fuel consumption and thermal comfort in your home. The optimal hysteresis value is usually 5°C, but this can vary depending on individual needs and external conditions.

Remember that the settings can be easily adjusted, and testing different values will help you find the golden mean between comfort and economy. If in doubt, seek advice from the boiler manufacturer or a specialist who can help you adjust the settings to suit your heating system.
