Genuine Rheem sickle element kit, part number 050262K. 4800 W at 240 V, copper sheath, 150 kW/m² watt density, gasket included.
4800 W is the highest of the common ratings and is normally used in larger tanks on off-peak or controlled-load tariffs, where the tank has to recover its full volume overnight.
Specifications
- Rheem part number: 050262K

- Sheath material: copper
- Watt density: 150 kW/m²
- Shape: sickle (curved)

What watt density means
Watt density is how much heat the element pushes through each square metre of its surface. 150 kW/m² is the standard, more compact fit. A 120 kW/m² element spreads the same wattage over more surface, so it runs cooler and scales more slowly — which matters most at the high wattages. We stock both.
Copper or Incoloy?
Copper is the standard sheath and suits most mains water. If your water is hard or from a bore, or elements have been failing early, fit Incoloy 800 instead.
Fitting notes
- Fit the supplied gasket — never re-use the old one.
- Clean the flange face back to bare metal and clear any calcification.
- Pull the bolts up evenly in a cross pattern. Do not over-tighten.
- Check the circuit and tariff support 4800 W before going up from a lower wattage — that is an electrician's call.
