“Great product to have on the hot water tank it will prevent burns/scalding (if set correctly), un certain about getting more out use out of the tank, but I can set the temp and know that no one will get burned/scalded.”
“I purchased this because I recently installed a deep and wide jacuzzi tub and could not fill it with hot water because my tank could not put out enough... and my hot water heater is only two years old, high efficiency, 60 gallons. I installed this easily, but I highly recommend skipping the PRO version. The stupid water temperature sensor severely inhibits the flow of water... it fills up over half of the pipe... I believe it is why people have complained about a drop in pressure. It throttles down a 3/4" line, making it feel like a 1/2"Not only is my 72" x 36" jacuzzi tub scalding hot, there is hot water left over now! I was skeptical, but now I am sold! I highly recommend this to those who want an economical alternative to an instant hot water heater.”
“Before this simple upgrade, one 20min shower would be all the hot water we would get. Now we can have 2 showers running at the same time, and have hot water left over for a 3rd complete shower”
“I originally had two commercial grade hot water heaters with Watts hot water extenders which worked quite well. After one of the hot water heaters failed in about 25 years, I received a new Honeywell AM-1 extender valve with the new hot water heater and made the mistake of throwing out the Watts valve. While expensive, the Honeywell valve was useless. It could not be adjusted to produce real hot water and tended to allow hot water to go back up the cold water line resulting in a real short jolt of very hot water on occasion.The appealing thing of this package is that it checks off all the right boxes. Check valves on both incoming lines prevent heat loss from cooling water coming out of the water heater sinking back and being reheated. This circulation is an energy wasting heat conduction loop if there is no check valve to prevent it. The check valve on the cold water line prevents the jolt of super hot water on startup. If you buy a valve which does not build in check valves, be sure to buy them separately.The washers with strainer screens provided prevent debris in the water lines from plugging up the valve working similar to the strainers on sink faucets. A good idea.Now the details:Low lead brass-appears good qualityTee connector provided: useful if your hot water heater has pipe configuration they assume(mine doesn't)Main Body: I was hoping to attach a hose connection to the hot water input. This has special shallow hose threading that basically needs the union provided. The union holds the very thin washer/strainer but requires a male pipe thread on input. I ended up buying a low lead brass short nipple to connect this union to the input hose. Expensive units monitor actual water temperature using a wax based sensor. From the description of this device, I suspect it is just a cheap proportioning valve mixing hot and cold water in a given ratio. But for my purposes, it is good enough and it works!The kit includes a temperature gauge for output temperature. The one I got is wildly inaccurate and useless.I used a good quality corrugated hose previously purchased for cold water input. It surprised me that I could not get a good seal with the thin washer/strainer provided in the kit I ran out of thread on the valve body when tightening. I ended up using both the thick washer provided with the hose AND the thin washer strainer. The combo worked.I used the provided corrugated hose for hot water output. This is not a standard hose! It has a shorter threaded connector piece than standard hoses. It needs the unusually thin washers provided. Do not substitute washers from a standard corrugated hose or try using these thin washers in a standard hose.”
“If you own a tank hot water heater buy this! It does a fantastic job of regulating the water temperature to level that will not scald and boost the performance of your hot water heater.”
“Looked at a LOT of options to improve hot water volume, including a new hybrid tank and a pre-heater. This seemed like an elegant approach and for the price, was easily most economical (on the initial expense...).Had a plumber install, only because I did not feel like messing with it.The product seems to work well. We are now able to fill our oversized tub with hot water, where previously, the tap turned cold halfwayThere are two basic adjustments, once installed. The plumber did turn the tank up to 140 F. And, the mixing ratio needs to be tuned to your preference. Ours is a bit on the cool side - the same position of the faucet will not be quite as hot. That is no big deal, simply turn the lever a bit more. The upper end hot water will still be very hot. The “homeowner” version of this device changes the ratio with a simple knob, this “commercial” model requires several wrenches.We have not run out of hot water and that is a huge win!”
