Rheem UV11698 Upper Thermostat Overview
The Rheem UV11698 Therm-O-Disc Upper Thermostat is designed for electric water heaters with a TOD-style high-limit configuration. It features two-pole high-limit contacts, allowing reliable switching and protection against overheating. The thermostat is rated to operate up to 150 degrees Fahrenheit, which fosters safe operation and helps prevent scalding. Installation compatibility with many Rheem systems makes it a strong option for replacements or upgrades in mid- to late-model heaters.
Key considerations: ensure your unit uses a TOD contact configuration and confirm the upper thermostat position in your heater. The 150°F limit provides a conservative safety threshold, but always align with your appliance’s recommended settings and local codes.
Eastman 60172N Double Throw Upper Element Thermostat
The Eastman 60172N twin-throw upper thermostat is designed to fit many water heaters from brands like American, Craftmaster, Rheem, and more. It features a built-in safety switch to help prevent overheating and offers an adjustable temperature range from 90°F to 150°F. The SPDT (single pole double throw) design enables switching between two outputs, which can support dual-element configurations and ensure precise temperature control.
Consider that compatibility depends on thermostat mounting style and the specific wiring scheme of your heater. If you plan to adjust temperatures for efficiency or safety, verify your unit’s element arrangement and required switching type before purchase.
EWH-00 Electric Water Heater Thermostat Kit
This kit from DROMIX includes both upper and lower thermostats for double-element heaters, offering a universal Tod/APCOM style compatibility. The kit supports a broad voltage range from 120V to 480V and comes with a one-year warranty. The included thermostats use Therm-O-Disc style construction, which is common in many electric water heaters and can be swapped with compatible APCOM styles. A practical choice for full thermostat replacement during a tune-up.
Note that this kit is non-simultaneous, meaning the upper and lower thermostats operate independently. Verify your heater’s electrical configuration to ensure proper installation and safe operation.
Reliance 9001954-045 Upper Thermostat With ECO
The Reliance 9001954-045 upper electric thermostat includes an ECO feature for enhanced energy efficiency in select electric water heaters. While the listing emphasizes the ECO option, it remains essential to confirm compatibility with your unit’s upper-element configuration. This thermostat is designed to deliver reliable temperature control within typical residential ranges and can be a suitable replacement option for engines expecting an ECO-enabled solution.
For buyers, it’s important to confirm that your heater uses the same contact type and mounting style as this model to ensure a straightforward swap and continued safe operation.
Rheem SP8295 Electric Thermostat
The Rheem SP8295 thermostat is a TOD-compatible replacement designed for Rheem water heaters. It uses a 110–170°F adjustment range with a thermostat tolerance of ±5°F and a differential of 5–15°F. The thermostat configuration is SPST (single-pole single-throw), making it straightforward for standard replacement tasks within compatible Rheem units. This model emphasizes ease of selection when repairing or upgrading a Rheem system, aligning with the brand’s typical electrical architecture.
As with any replacement, verify that the part matches your heater’s controls, including the required TOD style and wiring scheme. If your unit uses a different brand or a non-Rheem configuration, you may want to consider alternatives listed above for broader compatibility.
Buying Guide: Key Considerations For Choosing Water Heater Thermostats
- Thermostat type and compatibility: Confirm whether your heater uses Therm-O-Disc TOD, APCOM, or other style thermostats, and verify mounting and wiring compatibility before purchasing.
- Element configuration: Determine if your unit uses single or dual elements, as this affects whether you need an upper, lower, or dual-thermostat kit and whether SPST or SPDT switching is required.
- Temperature range: Most residential heaters operate safely between 90°F and 150°F; selecting a thermostat with an adjustable range within this window allows customization for safety and energy efficiency.
- Safety features: Look for built-in safety switches, high-limit protection, and ECO settings that help prevent overheating and reduce standby losses.
- Warranty and support: A one-year or longer warranty provides protection against manufacturing defects and offers buyer confidence for replacements.
- Voltage and compatibility: Ensure the thermostat supports your system voltage (often 120V or higher in electric water heaters) and check that it works with your heater’s brand and model.
- Ease of installation: Kits that include both upper and lower thermostats or clearly labeled components can simplify replacement, especially for DIY setups.
- Reliability and reviews: Consider models with established field use and positive feedback regarding durability and performance in typical household conditions.
