Description

Construction features

• Carbon steel tank with double layer vitrification and internal treatment according to standards DIN 4753-3.
• Anti-corrosion magnesium anode to ensure the durability of the tank.
• Condenser wrapped externally to the boiler, free from scaling and chiller liquid-water contamination.
• Auxiliary coil for use in combination with solar panels (TWCTZ-S only)
• Thermal insulation in thick expanded polyurethane (PU) (45 and 50 mm).
• Sheet metal coating painted color RAL839.
• Acoustically insulated plastic top cover.
• High efficiency compressor with R134a refrigerant.
• Electronic expansion valve.
• Finned coil heat exchanger with hydrophilic treatment for TCWTZ.
• Safety devices for high and low gas pressure.
• Electrical resistance available in the unit as a back-up with a safety thermostat, which ensures hot water at a constant temperature even in extreme winter conditions.
Electronic control and user interface for unit management:
• Tank temperature display.
• Domestic hot water set-point adjustment.
• Clock display and switch-on and shutdown timer.
• Electrical resistance management, in manual mode or in automatic integration.
• Anti-legionella cycle function, with activation timer.
• Indication of any alarms and malfunctions.
• Contact for integration with a photovoltaic system: the temperature set is raised to the highest possible value, on photovoltaic inverter enabling.
• ON-OFF contact to start the unit from an external switch.

Version

• TWCTZ-B: water heater with heat pump.
• TWCTZ-S: water heater with heat pump and additional solar thermal coil.
