Pellet heating system
Comfort, efficiency, environmental friendliness – these are the features that characterize Hargassner’s pellet boilers. As with all our biomass heating systems, flexibility and a wide range of variants are also a top priority for our pellet heating systems: this is how we ensure that there is a suitable wood pellet heating system for every need. We are proud that our Nano-PK and Smart PK boiler series won the “Energiegenie” Innovation Award in 2020. This underlines our unwavering commitment to innovation and excellence in heating technology.
Nano-PK
This is what makes it unique
The Hargassner pellet boiler from the Nano series is the right choice for anyone looking for maximum comfort and powerful heating performance. The “Nano” requires little space and can even be installed in a niche in small technical rooms. Due to the fully automatic technology it ignites and cleans itself. It independently maintains the desired room temperature and you can enjoy cozy warmth yourself.
Small, compact design
Can be installed flush with the wall on three sides and is therefore ideally suited for small heating or installation rooms and, depending on your local building regulations, it no longer has to be installed in a separate boiler room.
minimum space requirement:
0.69 m² for Nano-PK 32
Quick to transport
The Nano-PK boiler is a single-unit system and therefore very easy to transport. In most cases, it no longer has to be disassembled.
Quick installation
All accessories and piping are implemented in the boiler ready for connection. All the connecting components, such as the flue pipe, pellet transport pipes, etc. run upwards and away from the boiler. The easy installation saves you time and money!
Maintenance openings easy to access
All the boiler’s components have been arranged in a way that allows them to be accessed from the front or top easily.

Nano-PK
The future of heating
Most efficient
low-temperature boiler
The usable output range for the heating water circuit of the Nano extends from low to high temperature. In these heating systems, an outside temperature sensor smoothly adjusts the boiler output to the current heat demand. Economical buildings or transitional periods often require heating water temperatures that can be lowered to approx. 40°C / 104 °F. The low-temperature boiler therefore only ever generates as much heat for the radiators as is actually needed.
This saves radiation losses and less power is lost through the chimney.
Practical
consumption display
A reliable reminder on the display, remote control, mobile phone or tablet automatically provide a notification when pellets need to be refilled.
Fully refractory-lined high-temperature combustion chamber with a lambda sensor
Refractory has proven itself as the best material available in terms of heat storage, function and durability. The high combustion chamber temperature at full and partial load contributes to very good combustion efficiency of up to 96% and low emission values.
The lambda sensor regulates exactly the right quantity of fuel in every output range according to the pellet quality. This guarantees economical and low-emission combustion.
Automatic pellet transport
The hopper in the boiler is filled automatically at the set times and as required. A suction system transports the pellets via the fuel extraction system into the hopper
with the help of a turbine. With suction hoses, the pellets can thus be transported up to 20 m from a storage room.
A metering double rotary valve in a cast design provides 100% protection against burn-back by means of pressure compensation. The fuel falls through the rotary valve into the feed auger. This then transports the pellets directly into the combustion chamber.
Intelligent ash disposal
A distribution mechanism on the sliding grate compacts the ash and fills the ash pan to the last corner. This allows much longer emptying intervals. The display of
the boiler, the remote control or mobile devices reliably shows when the pan needs to be emptied. A filling reserve then gives you about another week. That is Hargassner pellet heating comfort!
Depending on the heating time, an automatic cleaning system for the heat exchangers is activated. This clears the boiler walls of residue, which then falls directly into the ash pan. In the Nano-PK 32, the ash is discharged by a transport auger in combination with an ash box.
Benefits of the large-scale pellet boiler series up to 330 kW
Eco-PK
The Eco series pellet boilers are ideal for any application that requires medium to high heating output. If up to six boilers are connected in cascade, or in series, an output of up to 2 MW is feasible. This is cutting-edge heating technology, complete with numerous energy-saving features, allowing heat to be produced with fewer emissions and at a lower cost when energy demands are high. The “Ecos” represent effective and efficient heating.
Energy-saving Eco operation
Speed-controlled EC exhaust fan with negative pressure control
Hargassner uses energy-saving EC exhaust fans in its Eco-PK boilers. The crucial advantage of this GreenTech EC technology is the significantly higher efficiency level of up to 95%. This saves energy and therefore electricity costs as well. The negative pressure unit constantly measures the pressure conditions in the combustion chamber. The “Lambda Touchtronic” control software regulates the speed of the exhaust fan, thus keeping the negative pressure at an ideal level. This concept ensures combustion with the lowest possible emissions and therefore maximum efficiency.
Energy-saving ignition
Thanks to the new design of the ignition element, the power consumption has been reduced to just 300 W (up to 1,000 W less) and, at the same time, the efficiency of the ignition process has been increased.
- Energy savings of more than 88 %
- Smart ignition monitoring
- Silent operation
One boiler – two options
Suction extraction system with day hopper for pellets
The wood pellets are suctioned out of the fuel storage room, temporarily held in the day hopper and fed into the boiler via a double rotary valve.
Direct fuel extraction system (RAP) for pellets
The wood pellets are transported by means of a direct auger from the pellet storage to the boiler.
Eco-PK Strong step grate
Closed grates in the combustion chamber with a high firebed – optimizes the gasification process and minimizes micro-dust emissions.
During the heating cycle, only the rear rotary grate is opened during the de-ash process. The ash falls down, the residual embers remain and enable further combustion of the newly extracted fuel.
The combustion chamber is cleaned completely before the boiler is restarted. Both grates open and cold ashes and foreign bodies such as stones or nails are disposed of.
For fuel with a very low melting point, the rotary grate’s additional “breaker function” will break the clinker.
Sophisticated technology
Eco-PK
Fully refractory-lined combustion chamber with standard recirculation
The refractory combustion chamber’s very good storage effect guarantees high combustion temperatures (even for partial load), minimizes the number of times the boiler has to be ignited and reduces emissions.
Every Eco-PK has flue gas recirculation integrated as standard to combat ash clinkering caused by dry fuel or fuel with a low ash melting point. Cooling the firebed prevents the ash of low-grade fuels with low melting points from melting. The residues can then be disposed of very easily via the ash extraction system.
Automatic pellet
transport
The hopper in the boiler is filled automatically. A suction system transports the pellets via the fuel extraction system into the hopper with the help of a turbine. With suction hoses and air, the wood pellets can thus be transported up to 20 m from a storage room.
A metering double rotary valve in a solid steel design provides 100% protection against burn-back. The fuel falls through the rotary valve into the feed auger in a constant quantity. This then transports the pellets directly into the combustion chamber.
Optimized cleaning for high convenience
ALL heat exchanger pipes – including the first pass – are cleaned at regular intervals. The edges of the auger turbulators efficiently remove any fly ash residue from the boiler pipes and this drops straight onto the ash auger. Both the fly ash and the grate ash are transported into a fully integrated ash box by just one ash extraction auger. The residues are crushed as they are being transported and then compacted in the box, resulting in increased annual efficiency and a higher degree of cleaning convenience.
With Eco-PK 70 – 200, only one drive is required for heat exchanger cleaning and ash extraction. Optionally, there are also different ash transportation systems in a 240 or 300 l ash bin.
Independent firebed monitoring
Non-contact sensors monitor the height of the firebed, so the most efficient combustion condition is achieved.
Lambda sensor control
The lambda sensor integrated into the control unit detects the calorific value of the fuel and thus regulates the optimum fuel/air mixture.
Integrated back-end protection
An integrable back-end protection with energy-saving pump and motorized mixer is available as accessories.
- Quick and easy installation
- Compact and cost-effective
