Stiebel Eltron Tempra 36 Plus Key Specs
Wattage: 36kW
This unit provides 36 kilowatts of heating power. This high output allows the heater to raise water temperature significantly even during colder months. You can expect consistent hot water flow for multiple fixtures. Compare this to lower wattage models if you need stronger performance for busy households or colder climates. Higher wattage generally supports higher flow rates.
Voltage: 240 or 208-Volt
The heater requires a standard 240-volt or 208-volt electrical supply. This is typical for major appliances in US homes. You must ensure your home has the correct voltage to operate the unit safely. If your electrical panel only provides 120-volt circuits, this model will not work. Check your existing wiring before installation to avoid compatibility issues.
Temperature Control: Digital temperature control
The unit features digital temperature control for precise settings. You can select the exact water temperature you want. This eliminates the need to guess or adjust mixing valves manually. Digital controls often improve energy efficiency by heating water only to the required degree. Compare this to analog dials which may have less precise temperature regulation.
Dimensions: 14.52" x 16.54" x 4.61"
The physical size is compact, measuring roughly 14.5 inches high and 16.5 inches wide. The depth is slim at 4.6 inches. This small footprint allows installation in tight spaces like closets or utility rooms. You can mount it on a wall without taking up much floor space. Compare these dimensions to larger tank-style heaters that require significant room.
Physical Design And Build Quality
The Stiebel Eltron Tempra 36 Plus presents a compact, rectangular form factor. According to the listing, the unit measures 14.52 inches in height, 16.54 inches in width, and 4.61 inches in depth. This slim profile allows it to mount on a wall without protruding excessively into the room. The gray finish offers a neutral look that blends with most utility spaces. The device weighs 19 pounds, making it manageable for installation but sturdy enough for permanent mounting. You do not need to worry about venting, as this electric model requires no exhaust pathways. This simplifies placement options significantly.
The front panel features a digital temperature control interface. This layout lets you set precise water temperatures directly on the unit. The power indicator light provides immediate feedback on operation status. You can reduce the water flow rate until the light stops blinking, ensuring optimal heating efficiency. The sleek design is intended to fit anywhere you choose to install it. Its compact dimensions mean it can be placed in closets, under sinks, or in dedicated utility rooms. The absence of bulky external components keeps the visual footprint small. This makes it suitable for homes where space is at a premium. The straightforward control scheme ensures you can adjust settings without complex menus. The build focuses on functionality and space efficiency. You get a reliable heating element housed in a durable, weather-resistant casing. This design supports long-term use in various indoor environments.
Setup And Everyday Use
Installation requires a robust electrical infrastructure because this unit draws up to 150 amps. You must have a minimum 300-amp electric service to support the load safely. The device operates on either 240 or 208-volt power supplies, which are standard for high-capacity residential circuits. Unlike gas models, it requires no venting, allowing flexible placement in utility rooms or closets. The compact dimensions of 14.52 by 16.54 by 4.61 inches help it fit into tight spaces without dominating the area.
Daily operation is managed through digital temperature control. You set your desired water temperature directly on the front panel. A power indicator light on the cover provides visual feedback. If this light begins to blink, it signals that the water flow rate is too high for the current heating capacity. You need to reduce the flow until the light stops blinking. This feature ensures you do not sacrifice pressure for temperature, allowing you to balance both effectively.
The sleek gray design blends into most utility areas. There is no need for complex exhaust systems or gas lines. This simplicity reduces maintenance requirements. You get reliable hot water on demand without the standby heat loss associated with tank models. The unit saves at least 15 to 20 percent on the hot water portion of your electric bill. This efficiency comes from heating water only when you turn on the tap. The digital interface keeps settings precise and consistent for everyday household use.
Electrical And Installation Checks
Before you finalize this purchase, verify your home’s electrical capacity. This unit demands a minimum 300-amp service and draws up to 150 amps. Standard residential panels often lack this capacity, so an upgrade may be necessary. Confirm your breaker box supports 240 or 208-volt circuits. The device requires digital temperature control integration, which is built-in, but you must ensure your wiring gauge matches the high amperage draw. Unlike gas models, no venting is needed, simplifying placement in tight spaces like closets or utility rooms. However, the lack of external venting does not reduce the electrical burden. You should also check if your current plumbing fixtures can handle the flow rate adjustments. If the power light blinks, you must reduce water flow. This unit suits homes with strong electrical grids. It competes with other high-output electric heaters by offering consistent performance without combustion risks. Ensure your electrician confirms compatibility before installation.
Check before you buy
- Confirm minimum 300-amp electric service capacity.
- Verify 240 or 208-volt circuit availability.
- Check wiring gauge for 150-amp draw.
- Ensure no venting is required for location.
