Combi 40 - 43 simplified system II.

Celsius Combi boiler

With pellet adapter door

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.

Accessories:

• Fire grates (grills) 
• Wooden pellet burner adapter door
• Filling/draining trap

Celsius safety heat exchanger

It protects the boiler and environment if the boiler is overloaded and the heating system can not heat distribute (There is not buffer tank and irregular usage).

Content of equipment:

• Celsius safety heat exchanger
• Vent valve
• Thermostatic security valve (opening temperature 98°C)
• Pressure security valve (2bar)

Applicable to the following boiler types:
Celsius classic, Celsius C and Celsius Combi boiler

F-Celsius anticondensing package to 65 kW

Boiler protection unit to prevent condensation
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.

Content of equipment:

• circulation pump (Grundfos UPM3 25-70 Hybrid)
• pump hollander (ball tap) 1 piece
• Celsius boiler protection valve
• to 65kW KVS 7,2

Principle of operation:

1. Starting the system (heating the boiler)
After the launching of the boiler, the thermic valve is fully closed towards the user (gate A) and remains in this condition until the fluid is warmed up by the heating source, gets the opening temperature of the thermic valve (corresponding to the calibration value, f.i. 55°C). During this step the fluid sent by the boiler fully recycles through the by-pass (gate B) so the boiler temperature rises very quickly.

2. Loading the system (heating the tank)
Reaching the opening temperature (f.i. 55C), gate A proportionally starts to open while gate B proportionally starts to close. The boiler temperature slowly rises, giving energy to the end user, but the returning temperature will not decrease below the calibrated temperature (f.i. 55°C).

3. System operation
Starting from point 2, the flow temperature progressively increases to fully open gate valve A. This will correspondingly close gate valve B. This happens at approximately circa 10k higher than the calibration or opening temperature (therefore in this example at 65c). Now the installation is fully operational the supply fluid temperature can increase to set value.
For example, if the valve opening temperature is 55°C, then it is totally opened in the direction of A → AB in case of +10°C.

Euroster 11E pump controller

Central heating/Utility hot water system pump controller

Euroster 11E is a modern microprocessor-based controller used to control central heating (CH) system pump or utility hot water (UHW) system pump.

The Euroster 11E controller features the ANTY STOP function that prevents idle pump rotors against seizing. Once the heating season is over, every 14 days the function automatically turns ON the pumps for 30 seconds. To that end the controller must be left powered up.

The Euroster 11E controller may be operated in two modes: it may control CH system pump or UHW system pump. In the former mode the CH system pump is engaged if sensor temperature has exceeded the preset limit. In the latter mode the UHW system pump is kept running until sensor temperature reaches the preset value.

• Set 1 has been complied for layouts in which CH system pump is control,
• Set 2 has been complied for layouts in which UHW pump is controlled.

Technical features:

B-Max 50 kW pellet burner equipment

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 50 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
