Properly setting the operation of a pellet boiler not only saves money, but also extends the life of the stove. Do you know how to program the device and what temperature of the pellet boiler is optimal? In this article you will find all the answers!
What temperature of pellet boiler will be appropriate?
Maintaining the right stove temperature is the key to efficiency and savings. The minimum temperature of pellet boiler (or more precisely: the temperature of the water in the pellet boiler) depends on the specific model of boiler and the type of heating system. It should be about 60°C to prevent condensation and corrosion of the device.
What about the temperature of radiators, on the other hand? Looking for the answer to this question, typing into the search engine search terms like "what temperature for pellet radiators"? The supply temperature of radiators should be set depending on the installation: for traditional radiators is usually 70 ° C, and for low-temperature systems such as underfloor heating, 30-45 ° C. In both cases, the return temperature should not fall below 55°C.
How do I set the blower on a pellet stove?
You already know what the minimum temperature of a pellet boiler is. In order for the device to work properly, you need to correctly determine the other parameters of its operation. An important role in the efficient combustion of pellets plays, among other things the blow, that is, the amount of air supplied to the combustion chamber.
Too little blowing can lead to incomplete combustion and more ash deposition, while too much blowing can lead to heat loss. Adjust the blowdown according to the power of the burner, the quality of the pellets and the current settings of the boiler controller. Use the pellet boiler manufacturer's guidelines and observe the combustion process - no smoke and light-colored ash indicate proper blowing.
What is the boiler's pellet feed time and feeder stop time?
Pellet boiler temperature and blowing on the stove - what other issues should I pay attention to? Another important issue is pellet feeding time.
The pellet feed time should be set according to the boiler manufacturer's guidelines and adjusted to the quality of the fuel and the heat demand. Too long intervals can lead to cooling of the system, and too short intervals - to inefficient combustion.
As a general rule of thumb, the higher the power of the burner, the more fuel should be supplied to the unit. However, care should be taken not to feed too much pellets - an excess of pellets will cause the fuel to fail to burn completely, reducing combustion efficiency and increasing the amount of ash. To avoid such situations, adjust the feeding time according to the specifications of the stove and the quality and calorific value of the pellets used.

Standstill time, i.e. the length of the interval between feeder starts, also plays an important role in optimizing combustion. This value should be adjusted according to the boiler's power and feeder time. For example, in stoves with higher power, the standstill time can be shorter to ensure a constant supply of fuel and to maintain the right temperature.
Pellet boiler temperature: can the stove settings be done by yourself?
Users can adjust basic parameters such as setpoint temperature and boiler schedules on their own. More advanced settings, such as blowdown or fuel feeding time, should be adjusted according to the manufacturer's instructions or by a service technician. It is important to have a basic understanding of how the furnace works, as improper settings can lead to inefficient combustion or even damage to the unit. After programming the boiler, observe the stability of the boiler temperature.
If you are not sure what parameters will be best for your home, consult your installer or use the owner's manual. An optimally set furnace is not only about saving money, but also about convenience and care for the environment.
