Great Valves

Review Posted 05/25/2021
These are super easy to install and super functional. Very easy to switch to "flush" mode to flush the water heater.

Takagi Unit must have add-on
By Richard W.

Review Posted 06/05/2020
Absolutely have to have valves like these for your tankless water heater system. These fit the Takagi T-H3-DV-P perfectly. Price kind of high, otherwise work very well.

VERY SATISFIED!!! This Is My First Whole House Hot Water Heater
By Brian M
Whitesboro, New York
Purchased 12/23/2019 |
Review Posted 01/31/2020
VERY SATISFIED!!! this is my first whole house hot water heater I wanted the best of the best and I got it. Pricey but you get what you pay for. The ability to adjust temperature from your cell phone is very handy. If your'e looking for one with all the whistles and bells than this is for you. Definitely get the Webstone service valves. Don't use Duravent only use 2" PVC pipe 2" Duravent is sized differently and not worth the hassle in getting a transition adapter and it's too much over kill. Let's talk WiFi, mine would not connect to my router it saw the router but would not connect problem was the connection on the WiFi module. After talking to Bosch I removed the display and installed it in the other port provided. (Note: they used double back tape to hole module in it doesn't just pop out as one might think. After I swapped it then it connected ASAP!!.
My only other issue was shipping damage. First one sent was discovered by carrier as damaged and turned back before it arrived to my house. The second one shipped in record time from eComfort, was also damaged from shipping box. Showed no signs of damage. however styrofoam was all damaged and case and cover were bent.
I do not attribute this to eComfort, I cant say enough good things about them. eComfort has been extremely helpful my hats off to all especially Bob D.
They sent a new door front from Bosch that was damaged. I installed myself.
Extremely satisfied with eComfort and you will be too.....
