EWH-01 Electric Water Heater Tune-Up Kit
This kit includes two 13-9/16 inch heating elements rated at 3500W @ 208V and 4500W @ 240V, plus upper and lower thermostats. Best for households needing a complete element and thermostat refresh on dual-element heaters. The included gaskets help ensure a tight seal and reduce leaks. Suitable for many brands such as A.O. Smith, GE, Bradford White, and more. Caution: verify element length and electrical ratings match your unit before installation. Warranty: one year.
2026 Upgraded EWH-03 Electric Water Heater Tune-Up Kit
This kit comes with two thermostats, two heating elements, and one element wrench socket. It emphasizes a risk-free guarantee and a precise thermostat range of 90°F–150°F. Best for users who want documented warranty support and clear temperature control, with fast heating due to EWH-03’s design. Limitations: ensure compatibility with your brand’s thermostat type, as Tod/APCOM interchangeability is noted but model-specific checks are still advised.
DROMIX Water Heater Element, 4500W 240V (2-Pack)
Two screw-in heating elements, 4500W at 240V, with chrome-coated copper tubes, designed to fit most dual-element electric water heaters. It reduces lime scale buildup in hard-water areas and includes a long insertion length for faster heating. Best for units using standard 13-9/16″ elements. Caution: verify thread size (1-1/2″ socket) and compatibility with your specific model.
HE 90240 Heating Element (EcoSmart Compatible)
9 kW 240V heating element designed as a replacement for EcoSmart Eco 18/24/27/36 models and similar brands. Best for upgrading to higher heat output in compatible systems, potentially shortening heating times. Ensure model compatibility before purchase. The element uses copper tubing and a screw-in design, which is common in many eco-friendly electric systems.
EWH-01 Electric Water Heater Tune-Up Kit (DROMIX)
This version of the EWH-01 kit includes two 4500W 240V copper heating elements with a 13-9/16″ insert length and two Therm-O-Disc style thermostats. Best for brands ≥ 30 gallons and for users who want interchangeable thermostats (APCOM compatibility implied). A one-year warranty adds a level of post-purchase security. Caution: confirm element length and voltage match your heater’s rating.
Buying Guide
What to consider when buying hot water heater elements and tune-up kits:
- Heater type and capacity: Verify your unit’s tank size, dual-element vs. single-element configuration, and the element lengths (commonly 13-9/16 inches).
- Voltage and wattage: Check your heater’s electrical requirements (208V, 240V, etc.) and ensure the kit or element matches for safe operation.
- Thermostat compatibility: Some kits use Therm-O-Disc thermostats; confirm compatibility with your model if you’re replacing thermostats as well.
- Material and corrosion resistance: Chrome-coated copper elements last longer in hard water environments but confirm compatibility with your heater model.
- Warranty and support: A one-year or longer warranty helps cover manufacturing defects and provides easier returns or replacements.
- Installation considerations: Some kits include a wrench or mounting hardware; verify the tools you’ll need for a proper seal and alignment.
Frequently Asked Questions
- How do I know which heating element length I need?
Measure the insertion length (from flange to tip) and ensure it matches your heater’s specification, typically 13-9/16″. - Can I replace both elements at once?
Yes, many tune-up kits include two elements and two thermostats to restore even heating across the tank. - Are Therm-O-Disc thermostats interchangeable with APCOM thermostats?
In many cases they are interchangeable, but verify compatibility with your model before mixing types. - Is a higher wattage element always better?
Not always; higher wattage heats water faster but must match your system’s electrical capacity and heat duty. - What maintenance benefits do these kits offer?
Replacing aging elements and thermostats can improve energy efficiency, heat speed, and hot-water consistency. - Do these kits work for EcoSmart or tankless models?
Some options are designed for EcoSmart-compatible models; check model compatibility to avoid mismatch.
