| Camco 2000W High Watt Density Element | Screw-In / HWD | 120V / 2000W | Universal replacements for many tanks |
| DROMIX EWH-03 Tune-Up Kit | Kit with Elements & Thermostats | 240V / 4500W (per element) | Full residential water heater tune-ups |
Camco 1500W Screw-In Element
This Camco screw-in heating element is presented as a low watt density design. The product listing highlights a low watt density heating element and UL listing, intended to reduce scale buildup and extend element life in some water heater applications.
- Low watt density element to reduce localized overheating.
- Listed features note UL compliance for safety standards.
- Screw-in form factor fits standard NPSM-style fittings used in many residential tanks.
When selecting a Camco screw-in element, confirm the specifications printed on the unit and the tank’s required voltage/wattage to ensure compatibility. The listing contains a conflicting wattage reference in features; verify model numbers and markings before installation.
Ximoon 5.5KW Titanium Flo-Thru
The Ximoon titanium flo-thru heater element is designed for spa and hot tub systems that use a flo-thru metal tube housing. Titanium construction resists corrosion and is suitable for high-salinity or chemically treated water found in spas.
- Compatible with Balboa, Gecko, and many spa control brands when used in the correct housing.
- Includes mounting hardware: terminal nuts, O-rings, and jam nuts for installation.
- Universal flo-thru design requires a metal tube style heater housing; not for standard screw-in tanks.
This element is targeted at spa and hot tub repair. Before purchasing, confirm your heater’s housing type is a flo-thru metal tube and the OEM compatibility list includes your controller or heater model.
Eastman 2000W Copper-Sheathed Element
The Eastman high watt density element offers faster heat-up times due to its wattage and density. A copper sheath provides corrosion protection and a traditional screw mount with gasket simplifies installation.
- High watt density and wattage designed for efficient, consistent heating.
- Screw mount design with gasket for secure sealing into the tank flange.
- Copper sheath for durability and thermal conductivity.
High watt density elements heat quicker but can be more prone to scaling in hard water. Confirm tank diameter and mounting thread (NPSM) to ensure fit and maintain recommended maintenance for longevity.
Camco 2000W High Watt Density Element
This Camco HWD screw-in element is a universal high watt density replacement designed to match many residential water heater applications. It includes a 1-11 1/2-inch NPSM steel bushing with a copper sheath and gasket for sealing.
- 1-11 1/2-inch NPSM steel bushing to fit common tank openings.
- High watt density profile for faster water heating.
- Gasket included; minimum recommended tank diameter noted on listing.
Camco’s HWD elements are intended for situations where the same voltage and wattage are required. Verify minimum tank diameter and element length to match your tank specifications before ordering.
DROMIX EWH-03 Tune-Up Kit
The DROMIX EWH-03 kit bundles two screw-in heating elements with upper and lower thermostats and an element wrench—aimed at full residential water heater tune-ups. Elements are rated at 4500W@240V (3500W@208V), with copper construction noted.
- Includes two thermostats (upper and lower) with temperature adjustment range and Thermo-O-Disc style.
- Two copper heating elements with gaskets for typical residential tanks.
- Element wrench included for removal/installation of screw-in elements and anode rod access.
Useful for complete maintenance or replacement when both elements and thermostats require service. Confirm element length, tank capacity compatibility, and thermostat interchangeability with your OEM parts prior to purchase.
Buying Guide: How To Choose The Right Heating Element
Selecting an appropriate heating element requires matching electrical, mechanical, and environmental factors. Use the checklist below to evaluate options for replacement or upgrade.
1. Confirm Voltage And Wattage
Match the element’s voltage (120V/240V) and wattage to your heater’s electrical circuit and original element. Using unsupported wattage or voltage can trip breakers, overload wiring, or damage the heater.
2. Identify Mounting Type And Thread
Common mounting types include screw-in (NPSM) and flo-thru tube elements. Measure flange thread size and element insertion length. Flo-thru elements require a metal tube-style housing used in spas and hot tubs.
3. Consider Element Material
Materials affect corrosion resistance and lifespan. Titanium is preferred for spa/hot tub environments and chlorinated water. Copper-sheathed
4. Watt Density: Low Vs High
Low watt densityHigh watt density
5. Compatibility With Controls
When replacing elements, verify compatibility with thermostats, control modules, and safety devices. Kits that include thermostats or thermo-discs can simplify full-system service but must match OEM specifications.
6. Installation Considerations
Ensure you have the proper tools and safety procedures: power off at the breaker, drain and relieve tank pressure, and use a correctly sized element wrench. Gaskets and O-rings should be replaced to prevent leaks.
7. Replacement Scope: Single Element Vs Kit
Decide whether to replace a single failed element or perform a full tune-up. Kits that include thermostats and multiple elements are efficient for older systems with multiple wear points.
8. Environmental And Usage Factors
Hard water, continuous heavy use, and outdoor or marine environments favor corrosion-resistant materials and lower watt densities. Spas and hot tubs require parts rated for those specific housings and chemicals.
9. Warranty And Certification
Look for UL listings
10. Verify Dimensions And Labels
Cross-check element length, sheath diameter, and thread markings with the existing unit or manufacturer specifications. Product descriptions sometimes contain inconsistent details—verify with printed labels and part numbers.
Comparison Perspectives
Below are practical comparisons to guide a purchase decision based on common scenarios.
- Residential Fast Heating: High watt density screw-in elements (Camco HWD, Eastman 2000W) provide quicker heat-up but require more maintenance in hard water.
- Hard Water Or Longevity: Low watt density elements reduce local overheating and scaling—look for low watt density models or protective coatings.
- Spa/Hot Tub Use: Titanium flo-thru elements (Ximoon) are optimized for corrosive spa environments and flo-thru housings; do not use in standard tank openings.
- Complete Maintenance: Tune-up kits (DROMIX) include thermostats, wrench, and two elements for a full system refresh and are useful for multi-part failures.
- RV Or Specialty Units: Use OEM-specified replacements for RV water heaters and appliances to maintain fit and safety; inspect element length and mounting style.
