Input:
Question: What to use for a float and how to attach it.
Document: Heating time is rather short, and in watching the on/off pattern of the sous vide controller, the unit is pulsed for no more than a second at a time once the water gets to the desired temperature. Another plus in my specific case, is that I can attach the water pump feed lines to the heater itself so that everything is fairly self-contained, and I can yank all the cooking parts out at the same time.
item did exactly what it was suppose to .. use it to heat water for a carpet machine . very happy with it
this product works very well in what it is intended for. i use it for heating grease for biodiesel and it works very well.
haven't been able to use it-won't fit into the tank opening of the tank i needed to thaw. going to give it away
Don't use it to help with even a small size pool to keep it warm, it just can't do it. Fine for a bucket.
Heats 3 gallons of water in 10 minutes, amazing! Do not drink the water though, only for use for work.
Great product for exactly what it is advertised for! Easy to use and worked exactly as advertised! Worth every penny!
Works very well on 5 gallon buckets. The outer protection is good, and I could use this heater in a plastic bucket.
I got this for when our solar water heater isn't working on rainy days and now is our cloudy rainy days will test out soon use with extreme care.
Easy, rapid water heater. Can boil 5gal water in 10 min, It was well worth the price, for what i use it for. I rate it Excellent!
