PID Logic Kombi combination boiler – Perfect combination of wood and pellet heating

The PID Logic Combi is a state-of-the-art combination boiler for the simultaneous use of logs and wood pellets. With an impressive nominal heat output of either 25, 35, or 45 kW, this boiler is ideal for small to medium-sized buildings. The innovative touchscreen control, precise lambda probe, and an efficiency of over 93% make the PID Logic Combi an economical and environmentally friendly heating solution.

Efficient wood gasification: Clean and durable

The wood gasification principle ensures almost complete combustion of the fuel. The spacious combustion chamber on the left side of the boiler allows for the insertion of logs up to 500 mm in length. A single load of wood will burn for at least 4 hours at full power and can be extended to a full day under lower load conditions. For optimal results, logs should have a moisture content of no more than 20%.

The two-stage wood gasification process reduces emissions and maximizes the energy utilization of the fuel. This protects the environment and significantly reduces fuel consumption.

Advanced pellet combustion

Pellet combustion takes place in the separate right-hand section of the boiler. An integrated storage container allows for convenient and space-saving pellet storage (80 liters for 25 kW, 148 liters for 35/45 kW). Automatic pellet filling from an external storage facility via a suction or conveying system is also possible.

Wood pellets are an environmentally friendly fuel made from natural wood shavings. They are subject to strict quality standards (DINplus or ENplus A1) and thus guarantee efficient and clean combustion.

Automatic switching between wood and pellets

The PID Logic Combi can automatically switch between fuel types. Once the loaded logs are used up, the pellet burner seamlessly takes over heating. This automatic switchover, however, only occurs when burning wood or pellets. This ensures a continuous heat supply without the need for manual intervention.

Comfortable controls and easy handling

The integrated control unit with color touchscreen offers maximum ease of use and controls all boiler functions. The lambda probe continuously measures the oxygen content of the exhaust gases and regulates the primary and secondary air supply to ensure optimal combustion with both wood and pellets.

Additional features such as an exhaust gas temperature sensor and automatic grate cleaning increase efficiency and ease of use. The large loading door of the combustion chamber makes adding wood easier, while the simple cleaning through the bottom door minimizes maintenance.

Reliability and safety features

The PID Logic Combi boiler is equipped with several safety features. A built-in safety temperature limiter (STB) immediately shuts off the boiler at a temperature of 95°C, while a safety heat exchanger effectively cools the combustion chamber through fresh water purging. Additionally, a thermal relief valve ensures maximum operational safety.

Even in the event of a power outage, important safety mechanisms remain active, ensuring that the boiler functions reliably in every situation.

Economical and environmentally friendly

With an efficiency of over 93% and the ability to efficiently use logs and pellets, the PID Logic Kombi is one of the most economical heating solutions on the market.The pyrolytic combustion of wood saves more than 85% fuel compared to conventional wood-fired boilers.

Thanks to its extremely low emissions, the PID Logic Kombi meets the highest boiler class 5 according to EN 303-5:2012 and the requirements of the German Federal Immission Control Ordinance (BImSchV) Stage 2. This means that it is not only economical but also environmentally friendly.

Flexible expansion options

The PID Logic Kombi can be expanded with various optional modules. These include, for example, a GSM alarm module and control modules for up to eight heating circuits, which can be regulated according to outdoor or room temperature. The pellet supply can also be optimally adapted using a vacuum system, an auger, or a large storage container.

Technical details and connection options

The boiler is available in 25, 35, and 45 kW output sizes and features standardized connections for flow, return, and drain. The flue diameter varies between 150 mm and 180 mm, depending on the output. All components are manufactured and tested to the highest quality standards, including TÜV and CE certification.
