Hello everyone! Today I will tell you about a fairly simple but effective piping scheme for a solid fuel boiler for closed heating systems. This information is especially useful if you want to do everything yourself and ensure stable operation of your boiler. I will also give some practical advice to avoid mistakes and increase the service life of the equipment.

Why do you need proper piping?
A solid fuel boiler is especially effective in combination with a buffer tank, which works as a heat accumulator. But it is not always possible to use this option - whether due to budget, space or other reasons. That is why it is important to know how to organize the piping without a heat accumulator in order to:
Minimize the likelihood of boiling the coolant.
Avoid condensation on the heat exchanger.
Ensure stable and safe operation of the system.
Main piping elements
1. Safety group
This is the first key unit. It includes a pressure gauge, air vent and safety valve. It is installed as close as possible to the boiler on the supply line. It is important to remember:
There should be no shut-off valves between the safety group and the boiler.
The operating pressure of the safety valve should correspond to the maximum operating pressure of the boiler (specified in the device passport).
It is better to direct the coolant discharge into a container or onto the floor, but not into the sewer. This will allow you to notice an emergency situation immediately.
2. Shut-off valves and taps with union nut
After the safety group, you can install taps with union nut - these are detachable connections that simplify boiler maintenance. They are mounted on the supply and return lines, and are directed towards the boiler.
3. Bypass line with thermostatic valve
The bypass line with a three-way mixing valve plays an important role:
It helps maintain the desired temperature of the coolant, preventing condensation.
The valve is triggered at a temperature of 45–55 °C. If you have firewood, choose 55 °C, for coal, 45 °C is suitable.
Important: the entire bypass line, including the return line, must be made of metal pipes.
4. Expansion tank
The tank compensates for the thermal expansion of the coolant: it takes away excess liquid when heated and returns it when cooled.
5. Circulation pump
For the system to operate continuously, it is better to install the pump on the return line. A coarse filter must be installed in front of it. This will protect the pump from debris, which can lead to its jamming and boiling of the boiler.
To ensure uninterrupted operation of the pump, it is recommended to connect it via a UPS (uninterruptible power supply). This is especially important in case of power outages.
Advantages of the correct scheme
Stable operation of the boiler: The heat exchanger will be reliably protected from condensation and corrosion.
Safety: The probability of emergency situations due to overheating of the coolant is excluded.
Durability: All elements of the system will work with maximum efficiency, extending the service life of the equipment.
Conclusion
That's it! A simple and reliable piping scheme will ensure the smooth operation of your solid fuel boiler. If you want to get professional help, do not hesitate - order the installation of a furnace near you from
