The past few years I have borrowed an immersion heater from a gemach. It has always worked out, b'H, but I always felt pressured to have to work within my time slot.
I am a big DIYer and know I can manufacture one, but I am having difficulty putting together a parts list.
A google search for immersion heater (and other variations) results in many options.
Anyone with hvac/plumbing background that can give me some advice?
Thanks
