Why is this considered a high watt rather than a low watt density element? What is the length and thread size?

The heater with 1 inch NPT flange has 350mm tube length. and it has 5500w wattage.

Whirlpool model e2f40rd045v. says for 1 phase 240v, 4500 for lower element. will this element work with my water heater?

It depends on whether your existing element is a screw in type or a bolt on type. This is a screw in type element. So if your water heater is a 240 volt with screw in elements then it will work.

Will this fit Ruud pe-30 d hot water heater?

Yes. It's 100% compatible with all water heaters that have ever been made. Including European models which use metric water flow.

I have a 240v hydro turbine that produces 1600w. Will this element work for me

We think you shoud use the lower power heater which is smaller than 1600w

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!
