SANCO2 GS4-45HPC-D Low Ambient Heat Pump Water Heater (Outdoor Only)

As a highly energy-efficient alternative to the traditional electric or gas water heater, our unique system saves money, reduces greenhouse gas emissions and eliminates the production of carbon monoxide.

The SANCO² heat pump water heater system consists of two parts. The heat pump unit, where the hot water is produced, using the CO2 refrigerant to extract heat from the ambient air, and the 43, 83 and 119 gallon storage tank.

High Performance:

The SANCO² unit has the highest UFHR (Uniform First Hour Rating) of any comparably sized Storage Electric or Heat Pump Water Heater.  The Natural Refrigerant (CO² ) used by the SANCO2 allows it to make and store hotter water than any other Heat Pump Water Heater. This means there is more energy stored in the tank which translates into more hot water delivered via the factory supplied Mixing Valve.

Energy Efficiency:

The SANCO² unit works to maximize the UEF value not only in the test lab, but also in real world operation due to several of its unique features:  

• Inverter Compressor Inverter C ompressors increase the efficiency of a heat pump by varying the speed of the compressor and hence the amount of electrical energy used.  
• DC Fan Motor & Water Pump T he other motors in the SANCO², the fan and water pump, are also powered by direct current (DC), just like the Inverter Compressor. This allows both to run at a speed based on load requirements to optimize energy efficiency.

Capacities:

• 43 Gallon System: GS4-45HPC + SAN-43SSAQA
• 83 Gallon System: GS4-45HPC + SAN-83SSAQA
• 119 Gallon System: GS4-45HPC + SAN-119GLBK

The reasoning for this product is that the Coil of the GS4 unit will continually draw heat/energy from the ambient air to the CO2 refrigerant being moved through the unit just like an air conditioner this will remove water from the ambient air even at the low ambient, this condensate is then dripped onto the base pan of the unit and could freeze to affect the rotation of the Fan and possibly the Pump.

To enhance the Unit operation in a cold Ambient we have created a new version of the GS4 to improve it’s operation in locations such like the Northeast US.  This unit is the GS4-45HPC-D and while it has the exact same performance and pretty close to the same efficiency (low ambient is slightly lower) it will have a 132W Heater energized below 34F to ensure no more freezing of the condensate.

This heater cannot be set up as an option or accessory for the GS4 unit as it does require wiring, unit control etc so this is why the new GS4-45HPC-D is created.  The GS4-45HPC-D does have a slightly higher price point to the GS4-45HPC unit but we believe that the price point considering the benefits to the reliability and longevity of the GS4 is still very acceptable Warranty:
