Ferroli TOR 24kW electric heating boiler (GCJO60EA)
Ferroli TOR 24 is a wall-mounted electric boiler designed for closed hydronic heating systems. Its nominal output is 24 kW and FERROLI specifies an efficiency of 99.5%. TOR 24 is the highest-output model in the TOR range and is designed for a three-phase 400 V 3N~/50 Hz electrical supply.
The boiler uses six 4 kW electric heating elements. Electronic control activates the elements progressively according to actual heat demand and prioritises elements with fewer accumulated operating hours, helping distribute operating load more evenly.
Heating-water temperature can be adjusted from 30 to 80 °C. With an optional outdoor temperature sensor, weather-compensated control automatically adapts the system flow temperature to outdoor conditions.
TOR 24 incorporates a high-efficiency circulation pump, 6-litre expansion vessel, automatic air vent, safety valve, water-pressure monitoring, pressure gauge and hydraulic bypass. Pump anti-blocking operation and multi-level frost protection are also provided.
The boiler supports a room thermostat and an external indirect DHW cylinder using a three-way diverting valve and NTC temperature sensor. External cylinder temperature can be adjusted from 30 to 60 °C and an anti-Legionella function is available for the external storage tank.
