Good for premanufactured home heaters.
Glad you had it, neither Lowe's or Home Depot had it, and putting a higher wattage element would had caused electrical problems. I installed it a year ago.

Serves its purpose well!
I utilized this element in a bit of a different manner, instead of running it off of 240 AC, I tied it to a set of solar panels that make 220 DC. They only make 1100 watts but the resistance of this element (this was attempt #3) matched my panels perfectly! On a good day my 40 gallon tank will make 190 degree water! That equates to almost 80 gallons of usable water with no grid electricity or gas!

Bad weld on power lug.
Arrived quickly, besides the bad spot weld the quality is good. The seal is probably a little big for use on a water heater, will replace with an o-ring. Sending back for replacement.
