Stiebel Eltron Accelera 220 E Heat Pump Water Heater
58 Gallon | High-Efficiency Hybrid Technology | Commercial & Residential Performance
The Stiebel Eltron Accelera® 220 E represents a major advancement in water heating technology, combining high-efficiency heat pump performance with proven German engineering. Designed for both residential and light commercial applications, this 58-gallon unit delivers exceptional energy savings, reliable hot water output, and long-term durability—making it a premium alternative to conventional electric or gas water heaters.
Advanced Heat Pump Technology for Maximum Efficiency
Unlike traditional water heaters that generate heat directly, the Accelera 220 E uses air-to-water heat pump technology to extract heat from ambient air and transfer it into the water tank. This process dramatically reduces energy consumption while maintaining consistent hot water availability.
- Heat pump output: approx. 1700 watts
- Uniform Energy Factor (UEF): up to 3.115
- DOE estimated annual energy use: approximately 1040 kWh
- Estimated yearly operating cost: approximately $169
The result is up to 80% lower hot water energy costs compared to standard electric resistance water heaters.
Optimized Hybrid Operation
The Accelera 220 E is engineered to prioritize heat pump efficiency while maintaining performance during high demand:
- Integrated 1.5 kW electric booster element
- Designed for approximately 90% heat pump / 10% resistance usage annually
- Automatic operation with intelligent system management
This ensures reliable hot water delivery even during peak usage, without sacrificing efficiency.
High Capacity and Strong Performance
With a 58-gallon storage tank, the Accelera 220 E is ideal for households and light commercial applications requiring dependable hot water supply.
- First hour rating: 50.3 gallons
- Operating temperature range: 42°F to 108°F ambient air
- Maximum water temperature: 149°F
This combination of capacity and performance makes it suitable for a wide range of applications, from homes to offices and small commercial facilities.
Built for Durability and Long-Term Reliability
Stiebel Eltron’s engineering excellence is evident in every component of the Accelera 220 E:
- Glass-lined steel tank for corrosion resistance
- Impressed current anode for extended tank life
- Wrap-around condenser design to prevent refrigerant contamination
- 3-inch insulation for low standby heat loss
The unit is designed for long service life with minimal maintenance, even in demanding environments.
Quiet Operation and Added Environmental Benefits
The Accelera 220 E operates with a low sound pressure level of approximately 52 dB(A) at 3.3 feet, making it suitable for indoor installation.
In addition to heating water, it also:
- Cools and dehumidifies surrounding air
- Improves indoor comfort in utility spaces
Smart Design and Installation Flexibility
The Accelera 220 E is engineered for versatility and ease of installation:
- Operates on a single 240V / 15A circuit
- Air flow rate: 324 CFM
- Can be installed in a variety of residential and commercial environments
- Up to four units can be installed in parallel for increased capacity
Its compact footprint and flexible airflow design allow installation in basements, mechanical rooms, and utility spaces.
