Gas condensing boiler FERROLI BLUEHELIX HITECH 24 RRT (EU), 0T4B2AWA
Wall-mounted gas condensation double-circuit/single-circuit boiler with secondary flow-through hot water heat exchanger / possibility to connect a boiler.
• Range of models: double circuit boilers - 24, 28 and 34 kW, single circuit boilers - 28, 34 and 45 kW.
• In single-circuit models - built-in three-way valve with servo drive.
• Unique condensation module "TERMOBALANCE".
• Self-regulating electronic gas valve.
• Double pressure control in the heating system. Manual filling.
A large depth of burner power modulation - up to 1:10 for various models - ensures high efficiency of the boiler, working both for the heating system and hot water heating, preventing its overheating even at minimal flow.
The boilers use very efficient modulating circulation pumps (pressure from 6 to 8 m depending on the boiler capacity) with low energy consumption.
Joint operation of the boiler with solar panels is provided.
Boilers have weather-dependent automation (outdoor temperature sensor is optional).
The boilers support the OpenTherm protocol and, using the additional remote controls ROMEO or CONNECT, the temperature of the heat carrier of the heating system can be changed to maintain the set room temperature.
New control panel with CapSense touch technology, without mechanical buttons; 2.8 inch graphic LCD display.
An optional relay board LC32 is available as an option, which expands the automation capabilities of the boiler to control additional external electrical equipment and alarms.
The boilers can work with both methane and liquefied gas, without the need for additional kits to switch to another type of gas.
The non-return valve of the smoke exhaust system, installed in the standard configuration of the boiler, allows easy connection to pressurized collective smoke exhaust systems.
