Electric Water Heater

[rickrichards]

So I have recently installed a drive-point well system (some may call it a sand point). The water is drawn by a 3/4 hp jet pump, which then spits out the water en route to a Bosch AE125 electric hot water heater.

The installation of the water heater requires that no plastic (PEX or other) be connected within 3 feet of the unit which I take to mean the inlet, or the outlet. The entire unit including the pump and the heater are housed in a temperature controlled shed which is attached to my cottage. What I would like to know is:

If I don't want to use stiff copper lines going to and from the hot water tank and would prefer something flexible, what are my options? And, what are the considerations?

I have looked at corrugated copper as one potential but have read some very negative things. Stainless steel braid maybe, although I am unsure about the pressure?

if it is the ability to work on the heater that is causing you twitterpation then why not continue with the ridgid copper pipe but add

a union on each line, at the w/h. then, the w/h can be removed with out using torch instead a pipe wrench would be the tool of the day


in my opinion, ss or corrugated are poo poo

actually, it is 18'' not 36'' on the pex/plastic pipe but we wont quibble
