Sherpa SHW

The heat pump water heater range, available in 300 l and 200 l versions, can guarantee a high level of efficiency thanks to the use of renewable energy.

Overview

PHOTOVOLTAIC INTEGRATION
Contact for integration with photovoltaic system that forces the ignition and raises the set point of the machine. The energy produced by the photovoltaic system is stored in order to reduce the costs of DHW production and maximize energy savings.

SOLAR MANAGEMENT
Compatible with solar thermal: the unit can work with a second source of energy such as solar panels (solar circulator management). Valid only for model 300S.

SMART CONTROL
The actual set of the heat pump is regulated by a climate curve, to prevent high pressure alarms from occurring in case of hot air taken from outside (over 25°C with water at 65°C, over 35°C with water at 55°C).

Functions

Available in two versions:standard model with heat pump, electric heater and 200lt tank (Sherpa SHW S1 200); model with coil for solar panels, electric heater and 300lt tank (Sherpa SHW S1 300S).
COP>2,6* ACS at 65°C
Energy class
: A
Working range in heat pump with air temperature from -10C° to 43C°.
Carbon steel tank with double-layer vitrification.
Anode magnesium anticorrosion to ensure the durability of the tank.
Externally wound condenser to the boiler free of fouling and gas-water contamination.
Thermal insulation in polyurethane rigid foam (PU) 45mm thick.
Outer plastic cladding Acoustically insulated plastic top cover.
High efficiency compressor with refrigerant R134a**.
Safety devices for high and low gas pressure.
Electrical resistance available in the unit as a back-up (with integrated thermostat with safety at 90°C), which ensures hot water at a constant temperature even in extreme winter conditions.
On-OFF contact to start the unit from an external switch.
Weekly disinfection cycle.
Possibility to manage the recirculation of domestic hot water or solar integration (presence of a dedicated temperature probe, flow switch input and control for an external pump). Valid only for model 300S
Electronic expansion valve for a precise control.
