What s new about the Accelera E? 3 of insulation High setpoint of 149 F 24W ECM powered fan reduces energy consumption Electronically impressed anode is maintenance-free Secondary thermostat enables Smart Grid/PV integration Refrigerant circuit outside of airflow behind a barrier for low noise output 1500 W heating element size Corrosion-resistant coated evaporator Stiebel Eltron USA 3
Side-by-side Comparison = R21 Heat pump starts when 60% of tank is tapped. *Tank starts at max. temperature and incoming cold water is 59 F Stiebel Eltron USA 4
HPWH Placement Requirements Accelera 220 E is versatile in its application potential Can be placed both parallel to a wall and in a corner In the corner position, it can be placed close to the wall Stiebel Eltron USA 5
What s new on the inside? 24W Electronically commutated motor (ECM) powered fan for 4.4% reduced energy consumption Closed-loop electronically impressed anode replaces sacrificial anode No anode to be replaced Anode also detects whether there is water in the tank to prevent dry firing Prevents hydrogen sulfide buildup in water Chain integral sensor Multi-sensor thermocouple measures tank temperature at different heights and calculates the amount of hot water available for use 1500W backup electric heating element Compressor is rated up to 650W at high water temperatures Stiebel Eltron USA 6
Display Displays tank content in gallons, current tank temperature User option for SI units More symbols for displaying functions Defrost mode Smart grid mode/secondary setpoint Menu Button Increase Button Boost Button Decrease Button 7
Menu Structure Tank Contents (104 F mixed, 59 F cold) Current Temp. Error Menu 1 (If error is present) Set Temp. 1 Error Menu 2 (If error is present) Set Temp. 2 (If connected) Change Units (0 is US, 1 is SI) 8
Error Code Display Error code reporting uses a doubling sequence to differentiate error codes If the error number is not equal to any these issues, find out which numbers sum up to that value If the display shows error code 6, both the dome and integral sensors have failed (2+4) If the display shows error code 34, the dome sensor has failed and the tank may be empty (2+32) Stiebel Eltron USA 9
Technician s Menu Technician s Menu is available for enhanced control of unit operation A service plug is needed to access the technician s menu Connect the service plug to the X1 port on the display board to access the functions When connected, the technician s menu will show additional menu options: Adjust the accuracy of the integral sensor Reload factor: Percent of tank used before elec. element activation Tank size adjustment: For board replacement, size of tank must be initialized Monitor evaporating temperature: Good for diagnosis Ability to disable integral sensor: Good if integral sensor displays error code and cannot be fixed 10
Benefits of a HPWH At a COP of 3, ~66% of energy costs due to water heating Generally better insulated tanks (Accelera has 3 insulation) Incentives from Energy Star & Utilities for homeowner purchasing HPWH Low power use and capability for the element to be disabled can be run off-grid more easily Can be tied to PV inverters to self use electricity in regions where net metering is capped. 11

Creating Hot Water using Outside Air, Natural refrigerant & Heat Pump technology! CLASS LEADING PERFORMANCE SIMPLE INSTALLATION RELIABILITY & QUALITY MAX TECH SOLUTION ENVIRONMENTALLY FRIENDLY PRODUCT CLASS LEADING EFFICIENCY
SANCO₂ Water Heater Split system HPWH, different to the integrated products Either a 43 or 83 Gallon Stainless Steel storage tank coupled with a remote 4.5kw (15,400 Btu/h) capacity Inverter Outdoor unit Why different? Based on successful Technology from a Global scale
Why the Split?? Typical Integrated HPWH are limited, SANCO₂ is Not Integrated HPWH use energy in the home to heat the water, Cooling the home year round, SANCO₂ uses Outside air, so only natural heat is used Integrated HPWH units are less than 6,000 Btu/h of Heat Pump, when you use a lot of hot water it needs the electric elements to turn on, aka HYBRID, SANCO₂ is 15,000 Btu/h and has no electric elements Integrated HPWH s are up to 24 taller than standard WH and require much larger clearances for airflow, SANCO₂ is virtually noiseless, can be mounted up to 50ft from the tank and the tank is designed so it can fit virtually anywhere
SANCO₂ Water Heater Only ½ Cold and Hot Water pipes connecting between Heat Pump and Stainless Steel Storage Tank are required No refrigeration work required CO₂ Refrigerant in a sealed system Heat Pump can be up to 50ft from Tank Stainless Steel tank requires no power and has 2 clearances
CO₂, A Natural Refrigerant CO₂ was first used as a refrigerant in the 1890 s before R12, R22 were even synthesized, and is making a comeback in the US for Supermarket refrigeration Refrigerant ODP GWP Toxicity Flammability Notes R134a 0 1,430 No No Fluorocarbon R410A refrigerant Refrigeration & HPWH 0 2,086 No No HP, AC & HPWH R407C 0 1,800 No No HP & AC CO₂ 0 1 No No Propane Gas 0 20 No Yes Flammable NH3 Ammonia 0 <1 Yes Yes Plume Study required Natural refrigerants CO₂: Extremely low GWP compared to ALL HFC refrigerants Non Ozone Depleting, Non Flammable, Non Toxic, Safe & Simple Future proofed against phase out
Performance & Efficiency GS3-45HPA + 83 Gallon Stainless Steel Tank Energy Factor = 3.84, NEEA Tier 3+ 1st Hour = 101 Gallons at 135 F delivered water temperature Over 120 Gallons @ 125 F delivered water temperature Recovery Rate 0.3 GPM of 131 to 176 F delivered directly to the top of the tank for immediate use

Power Usage & Demand Potential This graph shows the unit was shut off for 12 hours Total Energy use 5.63 kw, no reduction in HW performance Demonstrates that System can be operated in a Utility Demand Response program
Tested Validations The Sanden SANCO₂ HPWH Provides Domestic Hot Water to any home in Ambient temperatures down to -20 F and beyond Does not require a Back up Electric Element for the Storage Tank Only needs to operate 25% of the time, when compared to Synthetic Refrigerant HPWH s Is almost 4 x more efficient than electric resistance water heating and 40% more efficient IN COLD AMBIENTS than Synthetic Refrigerant HPWH s Can produce over 135 gallons of Hot Water daily including a 12 hour shut down period 10
