In this remodel & pool cabana house project with Architects Rick & Cindy Black we decided to use one Noritz tankless water heater to serve both houses. This was possible by using a Metlund D'Mand circulation pump. Unlike traditional circ pumps, this pump utilizes a thermocouple controller so it knows when the water is hot and shuts down the pump.

Matt, you look so young. I'm so old that in videos of me 10 years ago I still look old! I enjoy your channel! 😊
So glad your video popped up in my UA-cam feed. I have a combination boiler/hot water system in my home. It’s been good and bad, and maintenance is costly. My kitchen is on the opposite side of the house, and I feel like I waste water, trying to get hot water in my sink.
just found this video and how far you've come! amazing!
Wow how you have changed since this video was done
This video needs a revisit !
Wayne, thanks for your complements! We discussed an electric tankless but this Casita has a small kitchen & a full bathroom so we needed more hot water than a small unit could supply. The gas tankless was existing so all we had to do was pipe the water to the Casita and install the Metlund pump. They run about $300-400 plus install so it's a great solution. We also stubbed out for an outdoor gas tankless to be added in the future if necessary. Best, Matt
Thanks Joe! Really appreciate all your advice. I rented a Canon XA10 with a wireless setup and it was sweet! Hope to buy one in the next 6 months. Great suggestion on adding the website to the description. Best, Matt
The Bosch 1.5GPM unit would run a faucet but not a 2.5GPM shower and certainly not two fixtures at once. I would also expect it to need a dedicated 20amp circuit. The Metlund D'Mand pump seemed like a better solution.
Insufficient information. How is this thing plumbed? Does it return the water to the inlet of the tankless heater? Is there a checkvalve or two somewhere?
Fantastic Matt, great sound, nice edit and graphics, informative...you have hit your stride. Suggestion you might put your web site in the description or annotations..You Da Man!!
This is an awesome video! Still relevant almost 10 years later. However Metlund pump doesn't exist anymore. I can't find another water recirculation pump with the activation button like the Metlund. Is there an alternative you're aware of?
How does the water from the pump get back to the hot water heater and how is it connected to the heater once it gets back there?
Can anybody make me clear, so that cooled down water in the "hot water line" goes back to tankless water heater via recirculation line? And how do you know when your hot water is ready after pushing the button? How do you know when you need to push the button again?
No mention about how much insulation was put on both of the pipes between the buildings?
Hi. I have a 30 gal electric water heater in my house which is right by my bathroom so water is hot rapidly but if someone takes a long shower, for example, mine is just barely warm. Would this help that in any way? Or is it just to keep hot water available quickly? Thanks!
great video. I have 2 bathrooms less than 20 feet from each other. do you have to install a pump at both locations? or is it perhaps a single pump with a recirculation line installed as well? let me know if you can clarify.
The 3- to 4-second delay in getting hot water out of the tap in this video was the time it took for the water to get from the under-sink pump to the aerator on the faucet, not the time for it to be delivered 75 feet from the water heater. The actual time to get hot water from a "cold start" condition is how long it takes from the moment the pump is triggered with the pushbutton until it shuts off when it senses that hot water has arrived, and that can vary, depending on the distance to the heater, the size of the delivery pipe and the capacity of the pump. Low power pumps can take several minutes to deliver water. By using a high power pump, like those used for hot tub spas, the wait time can be reduced to around 20 to 30 seconds.
I don't understand how the cold water faucet (at the recirc pump location) doesn't produce hot water when opened?
Did you run a dedicated recirc line back to the water heater or did you install it like a retrofit which forces the hot water into the cold water line?
Does the cold water line gets warm like some other types of pump?
