Celsius Wood 90 - 125 industrial solid boiler 


The Celsius Wood Boilers have an outstanding, large firebox which can be fuelled with straw bales or wood logs. With its new design and increased efficiency is will provide efficient economic heating.
Celsius Wood Boilers are capable of producing heat to meet the needs of small factories, industrial and agriculture facilities.


In this category their 82% is an outstanding high efficiency.
These boilers have a large firing door(660x500mm).
Wood, log and straw bales are all adequate fuels.
Cleaning is easy due to the broad door. The insulation is 5cms thick and the multilayered steel door gives high efficiency as well.

Celsius anticondensing pump unit to 125 kW



Boiler protection unit for preventing condensation 2-way pump unit for solid fuel boiler with electronic servomotor for the control of the temperature. Condensation is an often experienced phenomenon during the use of the solid fuel boilers which is always harmful, will cause lifespan shorthening, efficiency drop, and higher heating costs.


  • Complete assembled units.
  • Space-saving, it has minimal space requirement due to compact design.
  • Insulated, the assembled units have insulating cover.

The written technical specifications refer to Wilo Stratos Para 30/1-8 pump in
the complete pump unit.

Celsius insulated buffer tank



Celsius buffer tanks:

To maximise the efficiency of a solid fuel heating system a buffer tank should be installed. When the boiler has produced energy to satisfy the heat demand, excess energy produced by fuel in the combustion chamber can be captured and stored in the buffer tank. The exception to this is when using wood pellets, where the pellet burner will automatically stop when the heat demand has been satisfied.
When the heating system have surplus heat ,the buffer tank stores it, therefore the wood boiler doesen't need an automatic draft regulator which ruins the burning efficiency.


Advantages of Celsius insulated buffer tank:

  • High quality insulation (C energy rating, EU complaint)
  • More economical burning
  • Lower pollutant emissions
  • Aesthetic design
  • Guaranteed continuous heating (for example: It can heat all night)
  • Hot domestic water modul can be connected

Euroster 813 controller



Operating principle:
The EUROSTER 813 control unit is a universal microprocessor controller with graphical display. The controller is responsible for the pump to operate on the basis of the difference between the set temperatures. It is possible to set up in the control an automatic disinfection function.


The control is responsible to turn on the pump on the basis of the difference between the set temperatures to ensure that the container is warmed by only the surplus heat, thus making energy savings.
The controller has a variety of automatic emergency circuit options.


You can set the emergency value of solar ebullience. There's an automatic vacation mode available, which takes care of cooling the storage to the set value, overheated by the solar system. This mode is important, if the storage is not used on a daily basis and ebullience of the solar panel will be induced. The keyboard of the control unit is lockable in the purpose of protection of your set parameters, which can cause an error.


The controller has a security sensor testing, if sensor sings, it will automatically trigger the pumps, preventing the ebullience. The controller has a sensor calibration mode, which allows you to avoid false temperature measurement by the long lines.


Treatment of controller
The graphics display of the EUROSTER 813 controller makes it easy to set up the controller. The options of setting the controller:
- Pressing the +/- buttons at the same time you can reach the menu.
- Pressing the -/ok buttons at the same time you can lock the keyboard.
- Pressing the +/ok buttons at the same time you can reach the manual mode, pressing the /+ button you can select the manually accessible devices.


After entering the menu you can set the following values:

  • time
  • disinfection (on/off)
  • modes
  • maximum emergency starting temperature of collector or boiler
  • minimal starting temperature of pump
  • maximum temperature of storage
  • starting and shutdown temperature of solar delta T
  • temperature of storage/hysteresis
  • calibration of solar sensor
  • calibration of storage sensor


Controller can be applied to:
In the case of Vacuum-tube control plane collector, mixed-fired boilers and buffers.
The pump must not be interrupted by other equipment!
