The Caria Pellet Boiler Has Arrived

The Caria has arrived at Kroll

The Caria CP23 23kW fully automatic hydronic wood pellet boiler is being installed and demonstrated at Kroll Dandenong

The boilers have been designed to heat hot water and must be connected to a heating plant and/or a domestic hot water plant within the limits of its performance and output.

The boilers have a maximum outlet temperature of 90°C (set point is max. 80°C) and a maximum allowable operation pressure of 3 bar gauge. Return water temperatures must not be lower than 55°C.

The boilers are not suitable for use as a direct water heater. Where potable or sanitary hot water is required, a matching indirect heat exchanger must be provided in the system.

The boiler must be fired by its original burner and pellet feeding screw.https://kroll-heaters.com.au/wp-content/uploads/2024/12/Screenshot-2026-06-20-124457.png

The boiler is suitable for use in an open vented or closed expansion vessel heating systems. The system must have a matching expansion system. Make sure that the open vented expansion vessel and pipes are protected against frost.

Second pass heat transfer combustion gas pipes have turbulator to maximize heat transfer to water and to clean the pipe inner surfaces.Please do not remove any of the turbulators, since this will cause loss of efficiency and damage to the boiler. The installation of an automatic low temperature control valve is a requirement to prevent condensation within the boiler. The warranty is void if this is not fitted and operated at 55°C. We recommend the LK Armatur LK810. See youtube.com/watch

The user and basic operational controls allows the time and temperature settings of the boiler and plant controlled from the boiler to be appropriately set by the client for the intended use of the building.
