Celsius Combi boiler

With pellet adapter door

Celsius Combi boiler

 

The Celsius Combi Boiler is our most up to date boiler.

Celsius Combi boilers were developed to operate with either dry wood or wood pellet (DIN+ quality, 6 mm diameter thick). Its structure is similar to that of a traditional wood burning boiler, however, its operation is a lot more economical with the use of highly efficient equipment. The boiler requires minimum maintenance and will continue to meet your heating requirements over its long lifetime. The boiler can be connected to any kind of central heating system, from radiator to floor heating.

 

The Celsius Combi Boiler with Wood Pellet burner is efficient and convenient because of:

  • Automatic turn on and turn off switching
  • Keeping fire and modulation (5 performance levels)
  • Increased savings due to possibility of 4 different pellet quality parameters.
  • Faster cleaning

 

These boilers are suitable for burning wood and in auto mode Wood Pellets may also be used. Thanks to its special design the boiler can utilize both fuels with outstanding efficiency. Celsius boilers are suitable for gravity or pump controlled heating systems for family houses, workshops, various farm houses, agricultural halls, institutions and greenhouses. Celsius solid fuel burning boilers have different models which are sized by heat output to meet your individual requirements.

  • Thermostatic security valve (opening temperature 98°C)
  • Pressure security valve (2bar)

 

Applicable to the following boiler types:

Celsius anticondesing recycling pump unit to 56 kW

 

 

Celsius anticondensing pump unit

Properties:

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

 

Application:
The anti-condensing pump unit can be connected directly to the solid heating source in the heating system or to the buffer tank without any additional device. The pump unit is housed in a compact insulation box which includes the circulation pump, the anti-condensing thermostatic valve, the on/off natural circulation clapet valve, the isolating valves and thermometers. It automatically adjusts the returning water to the heating source at the selected thermostat value setting.

 

Technical features:

  • Synchronous high efficiency Wilo Yonos Para RS/7-RKC circulating pump with progressive speed control.
  • Max. working pressure 10 bar
  • Max. temperature 100°C
  • Setting temperature 55°C
  • Natural circulation clapet valve: with external control, it can be set on or off according to the type of installation.
  • Temperature thermometers: 0-120°C.

 

Nominal opening temperature: setting temperature + 10 K.
The max. usable power up to 80 kW (at Δt 30 K) with synchronous circulating pump Wilo Yonos RS/7-RKC.

 

Working mode:

 

 

 

 

Starting the installation (boiler warming up):
After the starting of the boiler, the thermic valve is fully closed towards the user’s return (gate A) and this condition remains until the fluid, warmed up by the heating source, gets the opening temperature of the thermic valve (corresponding to the setting value, f.i. 55°C). During this step the fluid sent by the boiler fully recycles through the by-pass (gate B) and the boiler temperature rises very quickly.

 

 

Loading the installation (tank warming up):
Achieving the opening temperature (f.i.55c), gate valve A proportionally starts to open while gate valve B proportionally starts to close. The boiler temperature slowly rises providing energy to the user, however the return temperature will not decrease below the setting temperature (f.i. 55c)

 

 

Working installation:
Starting from the condition of point 2, the supply temperature progressively rises up to the full opening of the thermic valve (gate A) and up to the corresponding shutting of by-pass (gate B). This happens at about 10 K more than the opening or setting temperature (therefore in the example in hand, at about 65°C). Now the installation is on working and the supply fluid temperature can rise up to the set value.

 

 

Natural circulation:
The natural circulation of fluid through the clapet valve starts as soon as the circulating pump stops and the remaining energy of the heating source is transferred to the water tank. This function starts as a security device, when the pump stops due to blackout or failure, so avoiding that the temperature of the heating source can reach high levels of danger. To turn on the natural circulation function please turn the control screw anti-clockwise.
You can lock the clapet valve any time, turning the screw clockwise (this operation has to be done when the pump is working).

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!

B-Max 30 kW pellet burner equipment

 

Pellet burner


Low-power burner, designed for civilian buildings. It is equipped with a screw pump for loading.
Bmax Technology burners have an innovative self-cleaning system which works on regular intervals: with this system the fuel grid is periodically freed from possible residue that could interfere with the correct combustion or that could induce the suffocation of the flame. In this way, the possibility of turning off the burner and the consequent dispersion of fumes are avoided.

 

Safety equipment:

  • The B-Max 30 kW pellet burner contain safety equipments:
  • Burner safety thermostat (for preventing backfire)
  • Cutting valve fire (optional) (for preventing backfire)

 

Accessories:

  • Screw (60 mm)
  • Pellet tank (200 kg)
  • Compressed air kit
