SOLARFOCUS - Model PelletTop - Pellet Boiler
The biomass boiler is easy to integrate into the heating system of the building. The construction of the boiler is simple and provides easy excess for customer, plumber and service engineer. The boiler maintaines its high efficiency through the special cleaning mechanism which is fully automatic. However when wood pellets burn there remains always a bit of ash which is stored in the ash box of the pellet boiler. This ash box needs to be emptied usually 4 to 5 times a year. Highest efficiencies provide you a low fuel bill, Extremely compact design, Intuitive touchscreen boiler control, Visualisation on smartphones, PCs and tablet computers.
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!
- Turbulators clean the walls of the heat exchanger at regular preset intervals. Increased exhaust gas temperature results in a loss of efficiency.
Clean fuel exchangers save fuel! - AUTOMATIC means AUTOMATIC!
Uniform efficiency saves energy costs! Manual cleaning is not required. Maintenance free.
- The pellets are transported from the intermediate container by the feed auger into the single axis rotary valve. The single axis rotary valve hermetically seals-off the combustion chamber from the intermediate container. Six-chamber system - along an axis to the feed auger with a direct flanged-connection, maintenance free drive motor.
- 100% backburn-proof even if there is a power failure. Minimum power consumption. No chains or gear wheels - low noise and maintenance free.
- The pellets fall from above through the single axis rotary valve onto the stainless steel combustion grate. The fire is not disturbed as the pellets feed from ABOVE on the fire-bed, with no mixing of ash and embers with the pellets = best efficiency!
- The downfiring combustion technology automatically transports the ash downwards into the ash pan. There is no need to use a complicated mechanism to remove the ash.
- The combustion air sucked in is regulated by the ID fan.
- Efficient external rotor motor with stainless steel fan vanes, low noise, maintenance free with speed monitoring.
- Ignition of the pellets is fully automatic via a highly heat-resistant solid ceramic glow pencil.
- The glow pencil only requires 260 W. The glow pencil operates quietly and is maintenance-free.
- The pellettop has a generous intermediate container. The vacuum system turbine enables filling of the intermediate container within pre-set times in a closed circuit, maintenance free system.
- The boiler room and pellet storage room do not have to be directly adjacent to each other. The vacuum turbine is directly mounted onto the intermediate container for pellets.

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 pellettop is 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.
- 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 cylinders with expansion modules (optional)
- The pellettop also 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.
