CALORI pellet boiler – compact, efficient and low emissions

Short description

The CALORI pellet boiler is a compact, powerful boiler for wood pellets (6 mm diameter) and is particularly suitable for small installation rooms. Thanks to the slim design and the pellet container directly above the heat exchanger, the boiler can be installed to save space.

Technical data

Available nominal powers include 15 kW and 24 kW; Overall, the series covers a broad power range from approx. 11 to 30 kW. The device meets emission class 5 as well as the requirements of the Ecodesign standard and is classified in energy efficiency class A+.

Fuel and burner

Wood pellets with a diameter of 6 mm are used as fuel. The standard pellet burner has an automatic cleaning function, which makes operation less maintenance. An automatic ignition is also integrated, which makes the starting process comfortable and reliable.

Heat exchangers and efficiency

The heat exchanger is made of certified stainless steel and is equipped with inserted turbulators that recover more heat from the exhaust gases. As a result, the boiler achieves thermal efficiencies in the range of approximately 92.9 to 94.3%.

Control and operation

The modern APCK Slim control with touchscreen ensures intuitive operation. It offers PID function, automatic ignition and can control several pumps and a mixing valve in the basic configuration; Four pumps can be controlled as standard, but the APCK Slim is able to operate up to six pumps and a heating circuit mixer. Internet or GSM modules are optionally available, so that control is possible via eModul app or remote access.

Adaptive control, exhaust gas management and ventilation

The ADAPTIVE CONTROL controller adjusts boiler operation based on air flow through the heat exchanger, further optimizing efficiency and fuel efficiency. An exhaust fan stabilizes the chimney draft and prevents draft fluctuations, ensuring safe and consistent operation.

Installation and maintenance

The compact design and the pellet container located above allow it to be installed in very tight spaces. Installation in closed systems is possible provided that the safety requirements from the technical documentation are adhered to. The tubular heat exchanger is designed for quick and easy cleaning.

Scope of delivery and accessories

The scope of delivery includes a touchscreen, APCK Slim control, PID function, automatic ignition and the pellet burner with automatic cleaning. Optional accessories include GSM modules, various I-modules (I-1, I-1M), Internet modules (LAN, WiFi), several room thermostats (e.g. ST-292 v2/v3, DEFRO SPK Lux), wireless room thermostats, a set for wireless RS communication and a footstool.

Security and Guarantee

The guarantee covers 5 years on the tightness of the heat exchanger and 2 years on other parts as well as the perfect functioning of the boiler. These warranty conditions apply to boilers purchased from authorized partners in the Czech Republic. Safe commissioning and maintenance should be carried out in accordance with the enclosed technical documentation.

Advantages and areas of application

The CALORI pellet boiler offers a reliable, cost-effective and environmentally friendly alternative to fossil fuels.Thanks to its high efficiency, low emissions and versatile control options, it is suitable for single-family homes, small apartment buildings and commercial applications with limited installation space.
