The pellet heating system

The new space-saving pellet boiler from the Lower Bavarian premium manufacturer BRUNNER relies on efficient technology: By using condensing technology, a particularly high degree of efficiency is achieved. The pellet boiler can replace an oil heating system in existing buildings or be installed in new buildings. As of this year, the federal government has subsidised both variants with up to 45 per cent of the investment costs.  

The new pellet boiler measures just 0.53 square metres and 0.84 square metres, including the water storage tank. This makes the BRUNNER pellet condensing boiler the smallest in the world and therefore ideal for new buildings, where space is expensive and technical rooms are planned tightly. Even in narrow boiler room conditions in existing buildings, the system easily finds its place and replaces the old oil heating system. A pellet storage is set up where the former tanks used to be, and BRUNNER supplies the components for the installation at the same time. The smell of oil in the house is something of the past.     

Technical features

Regardless of whether it is a new build or a replacement in an existing building, the new BRUNNER pellet heating system solves every problem. It has the only pellet boiler on the market that is equipped with continuously variable fuel metering. A technically sophisticated operation mode directly on heating circuits and hot water tanks without a buffer tank is possible - and saves even more space. 

A tested supply air set is available for room air independent operation, while installation is quite simple. If a chimney renovation is necessary, BRUNNER also has a coordinated chimney renovation package ready. If chimney renovation is not feasible or desired, the pellet heating system is also available as a calorific value variant with a higher flue gas temperature. The flue pipe and chimney package come from the manufacturer and are guaranteed to fit. Charging pump and expansion vessel are already integrated in the boiler. 

The BRUNNER pellet heating system runs as serial equipment and free of charge online via tablet and smartphone, remote maintenance can be set up at any time. 

High efficiency, low emissions

A pellet condensing boiler has the smallest CO2 footprint of all. Thanks to condensing technology, the energy of the fuel used is almost completely utilised and the efficiency is significantly increased. When using surface heating systems (underfloor heating), the flue gas temperatures of the BRUNNER pellet heating system range from 28 to 38 degrees. The output of the boiler automatically adjusts to the heat demand in a wide range from 4 to 17 kilowatts and covers all requirements from old buildings to highly insulated new buildings. The emission values of the appliance are far below the strict legal limits even without additional separation and filter devices

Encouraged by the state

Efficient technologies that supply buildings with heat on the basis of renewable energies are financed by the state. For condensing boiler technology - including the new BRUNNER pellet boiler - this applies to both new and existing buildings as of this year. The funding rate is up to 45 per cent of the costs of the heating system up to maximum of 22,500 euros
