Smart Plug Plastic 120V 4 L x 2 W

My 4000sf home takes forever to heat up. This unit cycles the water for 5 minutes every 15 minutes which works great. The other feature is to use the bulb. Works great as well. I used the first feature for a few weeks so the unit learns our patterns. Then switched to dial to bulb and she's off and running great. No linger have to turn on pump when I'm home at odd times. Lil pricey but hey, we may much more for other comfort items... this one is for the household of 5 for confort... Read more

Installed in Dec. 2018. It needs a recirculating line installed by a plumber and a water pump (purchased separately). In our house, the distance from the water heater to the most distant point of use is approx 100 feet and we have hot water in 5-7 seconds. Still working perfectly in Aug 2022. Highly recommend using this instead of a timer. This device has a sensor placed on the hot water line, 2-3feet from the water heater, and turns on the water pump only when hot water begins to flow through the line. A timer has preset working time intervals and for example if you want to wash your hands at 2 a.m. you will have to wait for hot water as if you did not have a recirculating system. This device works any time and brings you hot water in seconds, during the day or in the middle of the night. Read more

I was excited when I ordered the Taco Smart Hot water controller. I followed the well written directions and "installed" smart plug. Then I waited. When the controller is first installed it cycles the pump on and off in what they call "burst" mode. The pump will run for 5 minutes (longer than necessary at my home) and then stay off for 10 minutes. It will repeat that cycle for 1 week while it learns your home's hot water usage. After a week of "learning", the controller stopped cycling the pump as it came out of "burst" mode into "smart" mode. From that point forward it simply never turned the pump back on. It appears that the controller never really learned my home's hot water usage. I tried relocating the temperature sensor and then waited another week. After the next week, the results were still unsatisfactory. This controller is very expensive to be so opaque. Even adding a simple LED to indicate that the temperature sensor is sensing hot water usage would be a much needed (but still insufficient) improvement. 7 days of maybe learning usage is simply unacceptable. Bottom line: It is impossible to tell if the controller is learning. It takes a complete week to learn anything. There is no battery backup, so a power blip will force it to forget what has learned. It is expensive. I ended up just buying a $15.00 digital timer with a battery back up. For less than 20% of the price of the Taco hot water controller, this digital timer allowed me to cycle the pump during waking hours. For my use, I found that 4 minutes on / 16 minutes off provides hot water to all faucets and doesn't throw any codes on my hot water heater. Over night during sleeping hours, the plug does not cycle the pump. For an additional $9.00 I added a smart plug that turns the digital timer off when I'm not home. All in I have a better solution for less than 25.00. Read more

Installed the controller to replace a WeMo domestic hot water (DHW) controller at the suggestion of our boiler installers. The Taco requires an outlet where the DHW pump is plugged in, and has a temperature sensor that has to be attached to the DHW supply line. For the first week the Taco records occasions where there is hot water flow, interpolating changes in supply temperature into demand for hot water. After that the Taco turns on power to the pump to anticipate demand. There is no programming required, not even a clock to set. The Taco switch will also go into vacation mode if it senses no DHW demand for awhile (36 hours, I think) where it will intermittently circulate hot water to prevent sedimentation in the lines. During initial operation, our household schedule has been very irregular with holidays, visiting guests, lots of overtime work, etc. If I was to try and program a timer to meet demand, I would have thrown up my hands in despair. Because I can't see the programming of the Taco switch, I don't know how much excess time the pump has been running. So far, even though we can't see any indication of its self-learning, hot water supply is almost instantaneous at even the most distant faucets in our big house, saving multiple gallons of water.

I bought this and a pump to replace a failed Taco pump that had this feature built it, which worked great for 6 years. This controller doesn't seem to work as well as the discontinued taco product that had the controller built in. Seems that the controller runs the pump too much.. and the learning functionality is far less capable as their previous product. Water seems to be always hot now, and no, the controller is not in the pulse function mode. It seems to be wasting energy and running all the time, or pulsing. I am going to contact taco direct, as they need to fix this product. Read more

Good quality product from Taco, as usual. Works as intended, hope it saves us some boiler run-time on our domestic hot water tank, coming from a constantly running circulator to this smart control- time will tell. Read more

The way you strap it to the pipe is kind of hokey...I tried the smart programing which worked for about week and then it stopped circulating and only had cold water. I didn't feel like messing with it so changed to the pulsating mode which works fine Read more

This unit is great!! My hot water circulating pump used to be on a timer and was not usually on when I got up in the morning. Now, with Taco's smart technology, the Smart Plug is constantly learning when I am using hot water and continually adjusts its run time accordingly. My wife and I are contemplating building another house and if we do we will definitely have a Taco Smart Plug installed. All in all, I would definitely recommend this to anyone who has a hot water recirculating pump in their home Read more
