FreezeFreeHose 20FT Heated Water Hose - Solid State Technology for Winter Outdoor Use | Perfect for RV, Camper, Farm & Garden Water Supply in Cold Weather

First few nights the temperature was in the "teens", and the hose did its job for my RV. However, one concern (and I am not sure how bad a concern it might be)...I can handle the fact that the water coming out is VERY warm, but what I WAS surprised about is the TASTE of the water after the hose is heated. I used the hose for almost two weeks without it being plugged in and everything was fine. After plugged in: Very strong odors, and the intense chlorine smell that is enhanced by the heat of the water is NOT pleasant. Bought a filtered water pitcher today, and it really did the job: All smells and chlorine are gone. But you have to wait for the water to cool down in another pitcher before it can be filtered, according to filter directions. Will unplug it when the nights are warmer.This hose works great but you have to be aware that the female fitting is closest to the bulky electrical component so it will not fit in small compartments. However, you can apply male/male and female/female to the ends to make the hose fit however you need. I would recommend getting the add-a-stat so your hose is not on constantly. The water does come out bath water temperature (which is good when it’s cold out). The hose will not prevent freezing if it is attached to any exposed hosing. The metal ends must be covered or protected from the elements. No leaks after two weeks of constant use. Seems sturdy.Update: I'm going through the second winter with this hose hooked up "full time" in mid-northern AZ. The sun has faded the color of the hose but it does not affect how well the hose works. No leaks. No extra insulation. The "add a stat" for $15 or so is worth it. It turns the heat on at 45-40 degrees ambient temp. Produces bathwater temperature water with a two foot snow fall on top of it. No worries of "fire".I just got back from my first cold weather camping trip with our 5th wheel. We went to Angel Fire, NM in what was suppose to be cold but not extreme weather. It ended up being a blizzard for a couple of days with howling winds and temps that dipped to -20. I wanted a GOOD heated hose for the trip so I bought this one. It worked PERFECT. It stayed flexible even in those temps. The electrical connection is well protected and stood up to days of constant snow, ice, and wind without letting moisture in and tripping the GFCI. I cannot comment on the longevity yet, but it seems very well made and I am optimistic.Have been using it for pool cover pump. I did have to loop it around the base area of where the pump sets. Otherwise it would ice up the intake of pump. Also note: A male to male garden hose is required. The heat hose plug must be dry at all times. Therefore the hose must be connected in reverse.This hose is a must have for all RV'ers. Hose works great and wasn't to expensive as others I have seen. Was in Flagstaff, Arizona during winter and glad I had this in the cargo bay. Forgot I even bought it, saved my plumbing.I purchased this product in 2019, and used it the first time we got freezing weather. Since I work with electricity every day for a living, I decided to see if it would leak water before I plugged it in to an electrical source. I'm glad I did. Once I had it connected to my RV, I turned on the water. The water instantly came gushing out of the electrical connection of the hose. I have a high quality water pressure regulator installed and preset to 40 psi. So I didn't have too much water pressure. This hose is unsafe and should be removed from the market before someone is injured, or electrocuted. It's a complete waste of money, and very unsafe. It leaks so bad I cannot even use it as a regular water hose, much less a heated one. Keep your hard earned cash and pass on this unsafe product.I’m so happy I went with this option instead of another kind of hose. It may be pricey, but this little hose was worth it! We’ve had days in the teens and the water comes out of the (cold) tap hot! I went with a shorter hose as well 10 or 15’), and am glad I did. It doesn’t coil well, so it does take up a bit of the basement space in our RV.I want to say first , Made in USA, that was the reason I bought it. This thing doesnt have a thermostat , so it runs continuously . I did just purchase the add a stat though (also made in USA) great product and fast shipping. Thanks for keeping products here in the states
