EWH-02 Electric Water Heater Tune-Up Kit
- Contains two 4500W 240V heating elements and the necessary upper and lower thermostats with protective covers.
- Thermostats support 120V–480V, with a temperature range from 90F to 150F. High limit at 170F.
- Copper heating elements with a 1″ diameter and standard 13-9/16″ length; compatible with tanks ≥ 14″ inside length.
Best for: homeowners who want a complete, all-in-one tune-up option that covers both heating elements and thermostats. This kit provides a direct path to restoring hot-water performance on most electric tanks 30 gallons and larger. A key limitation is that it targets common models; verify tank fit before purchase if your unit uses atypical components.
EWH-03 Electric Water Heater Tune-Up Kit (Wrench Included)
- Includes 2x 13-9/16 inch copper heating elements with gaskets, plus 1x upper thermostat and 1x lower thermostat, and a dual hex socket wrench.
- Temperature range 90F–150F with 170F high limit; TOD style and Apcom-compatible interchangeability noted.
- Elements are 4500W at 240V (3800W at 208V) and screw-in for easy installation in compatible units.
Best for: users who want a robust kit with an included wrench for straightforward installation and flexible thermostat compatibility. A limitation is the need to confirm the screw-in thread and tank length compatibility with your model to avoid incorrect fittings.
EWH-03 Electric Water Heater Tune-Up Kit (No Wrench)
- Contains two thermostats and two copper heating elements with gaskets; socket tool is not included.
- Elements are 4500W at 240V (3800W at 208V); thermostats support 90F–150F with TOD style interchangeability.
- Designed for quick replacement to restore hot water production and energy efficiency.
Best for: buyers who want a complete thermostat and element replacement set at a lower upfront cost, provided they have their own tool kit. Consider the absence of a wrench if you lack one; you’ll need a compatible socket to finish installation.
EWH-00 Water Heater Thermostat Set
- Includes one upper and one lower thermostat; TOD style and interchangeable with Apcom type thermostats.
- Designed for dual-element water heaters; compatible with 120V–480V systems.
- Helps restore precise temperature control; ideal when thermostats fail or drift.
Best for: buyers who need to replace thermostats only, especially when both upper and lower thermostats show wear. A potential limitation is that this kit doesn’t include heating elements, so you’ll need to source those separately if your unit also needs element replacement.
EWH-01 Electric Water Heater Tune-Up Kit
- Includes 2× 13-9/16 inch heating elements (3500W at 208V; 4500W at 240V) and upper/lower thermostats.
- One-year warranty; suitable for most dual-element heaters with capacity ≥ 30 gallons.
- Comaptible with many major brands’s models; restores efficiency and manages energy consumption.
Best for: buyers seeking a versatile kit with broad brand compatibility and a straightforward replacement path for both elements and thermostats. A limitation is that some usages require attention to the exact voltage and wattage rating matching your tank to avoid mismatches.
Buying Guide
Key considerations when choosing an upper element water heater tune-up kit:
- Tank compatibility: Confirm tank length, NPSM thread, and element size to ensure a proper fit. Most kits target tanks ≥ 30 gallons with dual elements.
- Voltage and wattage: Most components are rated for 120V–480V and 4500W at 240V; verify your unit’s service voltage to avoid underheating or overloading circuits.
- Thermostat type and range: TOD-style thermostats are common and interchangeable with Apcom models; check the desired temperature range (90F–150F) and safety limits.
- Included tools: Some kits include an element wrench; if not, you’ll need the correct socket to avoid damaged fittings.
- Maintenance goals: Determine whether you need heating elements, thermostats, or both. If only thermostats wear out, a thermostat-specific kit may be most cost-effective.
- Installation considerations: Always power off the heater and observe hot-water safety. Proper gasket seating and thread sealing prevent leaks and improve efficiency.
- Warranty and support: A one-year warranty is common for tune-up kits; this provides coverage for manufacturing defects but not for installation errors.
FAQ
