Thanks for sharing your video. I have done something very similar but incorporated the pump into our Alexa "Good Night" routine which turns the pump on when we head to bed and shuts it off after 10 minutes. Works like a charm and gives my wife instant hot water in our ensuite bathroom which is the furthest water faucet from the hot water tank.
California here🙋🏾♀️. I have a smart hot water recirculating system in my kitchen and I love it. I use the smart mode. When my hot water is turned on within 30 seconds I have hot water. And from what I understand it shuts itself off when the hot water isn't used for some time after that. Also when it's cold outside if the pipes reach a certain low temp, it warms up the water. Now i want 2 more for my master bath and the guest bath but i have no electricity under those sinks so would have to get someone to run electricity there. Oh and my pump seems to be larger than i want. It would be a tight fit. They need to make them more compact.
We have Alexa, but no smart switches (yet). However, the Watts recirc unit comes with a valve that you can install under a bathroom sink farthest from the hot water tank. When the hot water from the pump hits it, the valve closes, keeping the cold water cold without a separate return line. We have our timer turning on the pump every 15 minutes in the morning, then every 30 minutes during the day as we're usually both home. Then once every hour after 5pm and off after 10pm. The hot water comes out warm right away and we're not wasting any water. There is also a selector for constant on or off, too, so you can turn it off while you're away on vacation without losing your settings or TofDay. Best addition to our new HW heater and I wish I had installed one years ago! I considered a "switch" but the valve and very flexible timer cinched it.
I use motion sensors instead of relying on a switch. Making it totally automatic. I have sensors in the master bath, kitchen and outside a guest bathroom. So, I don’t have to even think about pressing a button or turning on a switch or a light(i seldom turn on the light in the master bath during the day.). Which has worked great.
Brilliant!
Thanks for the video. I've a few questions. It looks like you installed the pump on a T on the cold line entering the top of the water heater? Was the check valve right after the pump before the T? I already have a thermal expansion tank on my water heater. Will the recirculation pump play well with the expansion tank? Where should the pump and valve be in relation to the tank?
Nice Pelicans shirt. You in NOLA?
Just outside in Metairie. Not a pels fan but needed a Mardi Gras shirt 😂😂
This is a great idea and hooking it into your smart home is a great way to do it. I wish I could do this as well but we have a tankless water heater so it won't work unless I put a hot water tank somewhere in the system. I wish it would though because tankless heaters have an even longer run time before you get hot water and it's a major pet peeve of mine.
From my research you can do this with a tankless! You should look into it!
Excellent and great methodology...
Hi, the pump circulates through the crossover valve. What if for some reason, the crossover valve being blocked, will the system be over pressured? I don’t see anyone install a hammer arrestor or a relief valve. Thank you!
This is too awesome
This is genius. Great job on it! 🤗
Thanks will!!
To me the big deal breaker is running a line through the walls back to the water heater.
Clever! I’m going to try it.
where did you buy it?
I love how my tankless water heater takes 3 minutes to get hot water 10 feet away. Defeats the purpose of going green. So much waste water
