Maxa CALIDO Monobloc Heat Pump Water Heater

The Heat Pump water heater is one of the most economical systems to heat the water for domestic use or for small business activities.

Using free renewable energy from the air, the unit is highly efficient with high COP factor and low running costs. Its efficiency can be up to 3~4 times more than conventional gas boilers or electrical heaters.

The unit is especially designed for offering sanitary hot water for family use. It’s extremely compact structure and elegant design are suitable for indoor installation.

The Maxa CALIDO is available in 1 wall mounted version with 100 liters vessel and 3 floor standing versions with insulated tanks of 200 and 300 liters capacity:

• CALIDO 200/300: Standard version, heat pump with integrated storage vessel and electric heater.
• CALIDO 200S/300S: Standard version with auxiliary coil for use in combination with solar panels.
• CALIDO 200D/300D: Standard version with double auxiliary coil in order to have at the same time three energy sources.
• CALIDO PENSILE 110: Wall mounted version with integrated storage vessel and electric heater.

Main Technical Features for the floor standing versions:

• Steel tank with double layer vitrification.
• Anti-corrosion magnesium stick for assuring the durability of the tank.
• Condenser wrapped externally to the boiler, free from fouling and refrigerant-water contamination.
• High thickness polyurethane foam (PU) thermal insulation of 42mm.
• Outer shell made of grey colour plastic material (RAL 9006).
• Acoustically isolated top part plastic cover.
• Highly efficient compressor with the R134a refrigerant.
• High and low gas pressure protection.
• Electrical heater available in the unit as a back-up (with integrated thermo cut out with protection set at 90°C), assuring constant hot water even in extreme cold winters.
• ON-OFF contact for starting the unit from an external switch.
• Weekly disinfection cycle.
• Possibility to manage hot sanitary water re-circulation or solar water integration (presence of a dedicated temperature probe, flow switch input and command for an external pump).
• Electronic expansion valve for precise control.

Advantages:

• The actual set of the heat pump is controlled by a climate curve to prevent high pressure faults from the hot ambient inlet air.
• The integrated electric heater along with the weather compensator operate automatically to attain the desired temperature at all conditions.
• Predisposition for integration with photovoltaic system. After enabling the photovoltaic inverter, the set temperature will increase to the maximum value (according to the weather compensator control).
• Weekly automatic anti-legionella cycle.
