SOPHISTICATED TECHNOLOGY IN DETAIL

TECHNOLOGY and BENEFITS

At first glance, all pellet boilers are the same. But the difference is in the detail – and that is significant for low-maintenance and reliable operation! The SOLARFOCUS developments are protected by numerous patents. Pioneering technology for your pellet boiler!

Large stainless steel filling chamber
  • The generously dimensioned stainless steel filling chamber is designed to accommodate logs with a length of half a metre (max. 56 cm). 
    10-year guarantee as per maintenance contract on the filling chamber.
  • The filling chamber volume is decisive for comfort: The larger the filling chamber, the less often you have to stoke it with more wood.
    Large filling chamber – long burning time!
 
Hopper grate
  • The patented, funnel-shaped chrome-plated steel crucible provides the greatest heat volume with the smallest surface.
  • Resulting in lower heat losses.
 
Heat exchanger cleaning system
  • “Christmas Tree” Screws that clean the walls of the heat exchangers at preset periods. The screws are closely aligned to the heat exchanger walls, removing any residues and depositing them in the ash chamber.
  • AUTOMATIC means AUTOMATIC!
    Uniform efficiency saves energy costs! Manual cleaning is not required. Maintenance free.
 
Automatic ignition / ember retention
  • The boiler ignites the log wood fully automatically via a hot-air fan at the times you set.
  • You can select the "Ember retention" function: Embers then remain in the combustion chamber on the hopper grate for a certain time. This facilitates firing up after a complete burn-out
 
Generously dimensioned ash chamber
  • Large ash chamber, with high-compressed fireclay bricks.
    Easy to replace, no complicated setup work required.
  • Lengthens the intervals for emptying of the ash. 
    Individually mounted fireclay bricks are service-friendly and ensure a long service life for the high-temperature combustion chamber.
 
Induced draft fan
  • The combustion air needed in the various areas is sucked in by the speed-controlled induced draft fan. It is controlled by the microprocessor which is built into the control system by the measuring values determined by the lambda sensor.
  • Efficient external rotor motor with stainless steel fan vanes, low noise, maintenance free with speed monitoring.
 
Secondary air control with servo-motor
  • The lambda-controlled secondary air admixture allows unparalleled combustion quality with highest efficiencies even when burning different biomass fuels (pellets, log wood, waste wood).
  • Even in the partial-load range, the therminator II touch remains many times below the emission limit values.
 
Backup battery
  • The backup battery prevents overheating in log wood mode in the event of a power failure.
  • Corrugated stainless steel pipe for best quality and safety.
Flange for pellet auger
  • Blanking flange for subsequent retrofitting for pellet operation – already included at no extra charge. Pellet flange optionally on the left or right. 
  • The choice is always yours with the therminator II. If you decide after a few years that you no longer want to heat with log wood, you can simply expand the boiler for automated pellet operation. This gives you a full pellet boiler with efficiencies of up to 95.4 %.

THE HEART OF YOUR NEW HEATING SYSTEM

The intelligent boiler control ecomanager-touch

To meet your daily comfort requirements, control is particularly important. You control when the heating comes on and how warm it should be. Both changing outside temperatures and your own personal living habits are taken into consideration. If the therminatoris used in combination with a solar system, the burner only starts up when the required heating energy cannot be provided in full by the solar system. This prevents any uneconomical boiler starts.

ecomanager-touch
  • 7" VGA colour touch display 
    guarantees simple and intuitive operation
  • Powerful microprocessor
    USB and Ethernet interface
  • Power-saving standby mode – only 4 watts
 
A wide range of access options
  • Recording of ACTUAL values on a USB stick
    Remote query via Ethernet interface
  • Remote control via smartphone, PC and tablet computer
  • Info messages via e-mail or text message to your mobile phone (option)
 
 
Heating circuit and buffer charge control
  • 1 weather-controlled heating circuit (standard)
    Upgradable to up to 8 heating circuits with expansion modules (optional)
  • 3-point heating curve + heating periods individually adjustable
  • 1 buffer charging circuit (standard)
    Upgradable to up to 4 buffer tanks with expansion modules (optional)
 
Hot water or DHW heating

    Upgradable to up to 4 DHW tanks with expansion modules (optional)
  • Up to 4 fresh water stations can be controlled via expansion modules (optional)
    With or without recirculation pump
 
Control of the solar energy system
  • The  thermitnatoralso controls your solar energy system!
  • Optimum exploitation of solar energy via shared control. The boiler only switches on when the sun does not provide enough energy.
  • Up to 2 triple circuits can be controlled.
    Also suitable for high-efficiency pumps.
 
Remote control module touch
  • Operate your thermitnator from the comfort of your living room with a remote control module! 
    7" VGA colour touch display, on-wall/in-wall
  • Communication via Ethernet with the ecomanager-touch boiler control
    Access to actual and required system values

ecomanager-touch  with mySOLARFOCUS app for mobile phones

  • helps you to measure and control your heating system and your the hot water system.
  • If the boiler is used in combination with a solar energy system, the burner only starts when the required
    heating energy cannot be fully provided by the solar energy system. This prevents any uneconomical boiler starts.

weather man function for highest solar thermal gain

  •  if the SOLARFOCUS boiler is connected to the internet the weather server will update the boiler controller with weather forecast data.
  • through live weather data the controller is able to utilize the solar system as much as possible in order to reduce the pellet consumption and to make the system as profitable as possible.
