CALORI – Ideal boiler for small and narrow boiler rooms. A wide range of proposed capacities [11-30 kW] allows the boiler to be selected to match the area of each building.
♻️ Pellet hopper integrated with the boiler, located directly above the boiler body. This solution allows the device to be placed in small boiler rooms.
♻️ An effective and high-performance pellet burner with an automatic cleaning function. Equipped with air blow modulation with the "ADAPTIVE CONTROL" system, it ensures reliable operation.
♻️ The heat exchanger (body) of the boiler with a horizontal multi-pass design of fire tubes with the use of economizers guarantees high efficiency and low operating costs.
♻️ The design of the heat exchanger ensures comfortable cleaning of the ducts, making the boiler easy to maintain on a daily basis.
♻️ Simple operation thanks to the APC K SLIM controller guarantees intuitive operation and self-control of the controller's operation.
⚡ Heat exchanger made of certified high-quality steel
⚡ High thermal efficiency in the range of 92.9 to 94.3% due to increased heat recovery from the flue gas
⚡ APC K SLIM ADAPTIVE CONTROL controller operating 4 pumps - central heating, hot water, valve pump and an additional pump. Control of one mixing valve. Preview and change of controller parameters via an additional Internet module - option at an additional charge. Possibility of connecting a GSM module - option for an additional charge
⚡ The boiler is adapted as standard for installation in a closed system, provided that the protection is installed in accordance with the boiler's DTR
⚡ ADAPTIVE CONTROL control – regulation of boiler operation based on the air flow through the exchanger
