Replace heating elements can be found at amazon, click here and take a look: Amazon com rheem heating element . I hope this was helpful... cheers

If it is gas, check if the gas valve is open and the pilot light is on. If it is electric, check the thermostat on the electrorod, it should be around 120 degree. Good luck!

no way to convert lp to electric..more cost effective to buy electric water htr..by far

Electric water heater can be repaired by homeowner
If I understand correctly, water heater is producing no hot water.
Reset button clicks in, but still no heat.

Three initial things can be causing this:
1) No power to water heater. Test across top two screws on upper thermostat for 240V. Red and black wire are attached to these screws. Screws are marked 1 and 3. Upper thermostat is same that has reset button. If power tests 120 across screws, then breaker may be off on one leg. If no power, then start testing at breaker.

2) Upper thermostat is bad. Replace thermostat with generic upper thermostat available at hardware store.

3) Upper element is bad. Test and replace element using Rheem 4500 watt element available at hardware store. Image shown below. Look at label on side of tank for element wattage. Rheem puts 4500 watt elements into all their 240V electric water heaters.

If upper element is burned out the tank will not heat any water.

Rheem 4500Watt element


Upper thermostats are generic and interchangeable:

Check the elements, if you have access to a meter to check them. If they are getting power to elements and you have no hot water.
The elements are not working correctly. I had some elements check out ok till the thermostat's turned on and the elements didn't heat.
Sounds like the elements are bad.

Check the thermastat, located in removable panel. warning dont set above 120- 130. If not the case it could be a bad heating coil. Easy to change in electric just googl a how to sitr. If your not Real Handy with Your Handa I would recomend calling a plumber to check heating element, Could be cheaper to replace
