PID Logic Kombi – The perfect combination of wood and pellet heating

The PID Logic Combi is a modern combination boiler that unites the advantages of log and pellet heating systems. With selectable nominal heat outputs of 25, 35, or 45 kW, this boiler offers an energy-efficient and environmentally friendly heating solution for small to medium-sized buildings. Thanks to innovative technologies such as touch controls, a precise lambda probe, and an impressive efficiency of over 93%, the PID Logic Combi meets the highest standards.

Efficient wood gasification: Sustainable and powerful

The principle of wood gasification ensures almost complete and clean combustion of the fuel. The boiler's generously sized combustion chamber, located on the left side, allows for the insertion of logs up to 500 mm in length. A single load of wood can provide up to 4 hours of burn time at full power. At lower loads, operation throughout the entire day is even possible.

The two-stage wood gasification process protects the environment by reducing emissions and maximizes the utilization of the energy stored in the fuel. For optimal results, the firewood used should have a residual moisture content of no more than 20%.

Advanced pellet combustion

A separate boiler compartment on the right side is provided for pellet combustion. An integrated hopper offers sufficient space for 80 liters of pellets in the 25 kW version and 148 liters in the larger 35 kW and 45 kW models. Alternatively, the boiler can be connected to an external pellet supply via a suction or conveying system to further increase convenience.

Wood pellets are an environmentally friendly fuel made from renewable raw materials such as wood shavings. With quality guarantees like DINplus or ENplus A1, the pellets ensure a clean and reliable heat supply.

Automatic switching between wood and pellets

The PID Logic Combi boiler supports automatic switching between fuel types. As soon as the loaded logs have completely burned, the pellet burner automatically takes over. This ensures a continuous heat supply – completely without manual intervention. This exceptional convenience makes the boiler ideal for users who prioritize both flexibility and efficiency.

Intuitive controls and easy handling

The PID Logic Combi is easy to operate thanks to its color touchscreen interface. The integrated lambda probe continuously measures the oxygen content in the exhaust gases and optimizes the air supply for ideal combustion. This technology effectively supports both wood and pellet fuels.

Additional practical features such as an exhaust gas temperature sensor, automatic grate cleaning, and a large loading door for firewood make daily use of the boiler particularly convenient. Maintenance is kept to a minimum thanks to the easily accessible cleaning elements.

Security at the highest level

The PID Logic Combi boiler features numerous safety functions to ensure smooth operation. A safety temperature limiter (STB) shuts off the boiler in case of overheating, while an integrated safety heat exchanger ensures rapid system cooling. Additionally, a thermal relief valve provides maximum operational safety.

Even in the event of a power outage, key safety elements remain functional. This reliability makes the PID Logic Kombi a safe choice for any application.

Economic efficiency and environmental friendliness

With an efficiency of over 93%, the PID Logic Combi is among the most efficient heating systems in its class. Thanks to the pyrolytic combustion process, fuel consumption is reduced by up to 85% compared to conventional wood-fired boilers. This not only saves the user money but also conserves resources.

The extremely low emissions meet the strictest environmental standards, including boiler class 5 according to EN 303-5:2012 and the German Federal Immission Control Act (BImSchV) Stage 2. The PID Logic Kombi is the ideal solution for anyone looking for a sustainable heating alternative.

Expansion options for maximum flexibility

Numerous expansion modules can be easily integrated, increasing the boiler's functionality. These include control modules for multiple heating circuits, a GSM alarm module, and various storage container systems. Particularly convenient: For pellet supply, auger systems or screw conveyors can be used to meet individual needs.

Technical specifications

The PID Logic Combi is available in three power levels: 25, 35, and 45 kW. It features standardized connections for the flow, return, and drain, and is equipped with an exhaust outlet whose diameter varies between 150 mm and 180 mm depending on the model. All components are TÜV and CE certified to ensure the highest quality standards.
