I have this. You have to connect the two pipes under the sink in the furthest part of the house from the water heater. For us, we picked a spot downstairs in our master bathroom since our master bedroom is on the ground floor. Our shower would take 2-3 mins to warm up which was a huge waste of water. I now have this connected to a smart plug. A few mins before I want to shower I ask Alexa or Google to turn on my water heater. It turns it on and within 10 mins I have instant hot water. I also have a smart activity setup that says to turn this off 10 mins after it is turned on. This protects it from running mom stop if you forget to turn it off. Using the built in timer to turn it on and off only works if you have a set schedule and shower at the same time everyday.

I've had one of these for years. Just to reiterate it makes both the hot and cold water "warm", so you have to run the water a bit to get really warm water or really cold water, since the water in the hot and cold pipes have been warmed up.

best pump in the market been using for 4 years 5000 sqft home i place two pumps and 4 sensors different areas in the house
turn on timer 5.00 am to 11.00 pm it use to take 4 min before i get hot water up stairs wasted so much water. Now 30 seconds i have hot water, no complaint this will save some $$ because you not waiting for hot water to filter through

As far as how much i really do not care because i need hot water entire house at any given time.

Yes cold water tap will take 30 seconds before you see cold water because you have hot water filtering through the cold water pipe.

I'm confused by the people asking about wasted energy while using this. Are you referring to the cost of the energy it takes to heat the water that replaces the water pulled from the water heater, in the event that you have this running on a schedule and don't end up using the water soon after? Or the cost of running a pump for a few minutes?

Assuming the former— Let's remove the discussion of schedules for a moment, and say that you wake up and run the water for ~3 minutes to get it hot so that you can wash dishes or whatever. Pressing a button and doing other chores while this thing runs and coming back then getting hot water instead of running cold water down the drain seems like a no-brainer in this case, right? Am I missing something? Are there downsides to running hot water through cold pex lines (besides temporary warm water when you were expecting cold) or anything like that?

Our community has rated this post as helpful. If you agree, why not thank jockovonred

Thank you.

So there's savings in water but waste in energy by having to continuously heat new water coming into the tank. Wonder what the cost/benefit to this is (water saved vs. energy used)?

These 2 articles do some math regarding energy savings:

There's some math involved in calculating the energy costs:

To clarify, my question was total cost/benefit.

-cost of energy to run hot water heater
-cost of energy to run device
-sunk cost of the device
-savings of water recovered

*I understand that the convenience of instant hot water can be "priceless" and that is the tradeoff for the benefit for some people.

Just trying to understand the value proposition for this device.

Save water that would otherwise go down the drain while waiting for hot water at fixture. Definitely wasting energy.

I think I'll wait with the all of the West in drought, I think there will be rebates soon for water-saving devices.
+1 right now water is cheap compared to energy even in PHX. That will change...

It has a built in manual timer so that it doesn't have to run continuously. If you want minimal waste, use a smart-plug with the pump and only turn on a few minutes before a shower, then turn off when you're done

I put one in last year and love it.
There was no noticeable increase in electrical use but we saw instant savings with our water bill plus the luxury of instant hot water.
There is about a 50' run from our electric water heater to our master bath shower. I use a Wyze Google enabled smart outlet to control it and a 30 minute run time limit in case I forget to turn it off using the Wyze app.

Quote from yas070 :
I guess all depends you want hot water instant or wait 4 min?
so what the cost for heating hot water all day verses waiting 4 min every time you want to use hot water.?

I not worried about the extra cost I just need hot water available to me at any given time of the day.
I'm just saying it may not save $$

Its not "instant" if you have to wait 5 minutes for it to circulate

I posted to the thread, not your comment, so have a wonderful day.

As the OP mentioned, like the majority of installers, these will be placed on a wifi-enabled plug for circulation on-demand, and require several minutes of circulation before the water gets hot.

The only solution to true "instant" hot water is to install a mini water heater under the sink. I get hot water in less than 5 seconds with this Bosch unit

Would this help with frozen pipes? I've read that some people have used this to circulate water overnight using a smartplug to get the water flowing instead of just dripping the faucet.

This seems to be a bad idea. It wastes energy. Also, you shouldn't drink the water from your hot water tap .... and now you are putting your funky tasting and hot water into your cold water tap along with any lead that may be in dissolved. $185 for much worse water quality and higher energy bills.

I know this may have already been answered, but the simple answer is yes. Plumbers will tell you it costs about $1/day to run it all of the time.
