Question: what is the heating range of this water heater?
Document: great little water heater for my cabin in the sandhills of North Carolina.My dad had one of these water heatersmany many years ago
Great heater for the shop if you need to heat up a bucket or pail of water for shop use. Also great for tile setters to heat up water for tub saw. Takes about 10 minutes.
Great sous vide heating element for a DIY setup.
It doesn't seem to do much other than serve as a weight, but if you leave it in it gives off a strong plasticky smell -- I didn't even attempt to taste the water I heated with it in there.After pulling the disk out, I heated a pan of water and tested the heater again by making tea. Perfect. No off-flavors at all and faster than the stovetop.
I wish it would be a little bit longer so it could heat more water. It works great. Specially on winter time.
I buought this to heat a small tank of water and it works very well for that. A gallon of water nearly gets to boiling in about 8 minutes. Seems very well constructed.
I would not leave this unit plugged in un-attended for any length of time. it does not have a thermostat, and will continue to heat the water. I would worry about the parts and washer getting to hot. If attended, and monitored you have no problem, you can un-plug/turn-off the unit to regulate the heat. I just got a new 40 gal washer, and have no worries it will heat that parts cleaner just as well.
The handle is shorter than in the photo by as much as 2/3. Still, it worked well when I tried it. I'll probably make a longer handle out of PVC -- which I was planning to do anyway, so not a huge deal.I'll be using this with a propane burner for brewing beer.
My reason for purchase was to keep my parts washers warm....It would actually heat a 20 gallon parts washer to the point of being to hot to handle. The parts, which are normally very greasy and oily, come out amazingly clean, with little to no effort. I simply use a small amount of de-greaser, and allow the tank to heat up, which only takes about 5-10 min.
I knew what I was getting into.
Answer: yes
