I installed one in a house we renovated over this year. Had to do away with the flue pipe for the 40 gal water heater because it was in the way of the new shower we were installing. Was never a fan of the tankless water heaters in the past but it seemed like they had come a long way. I put in the Navien NPE 240A2 along with the Navicirc valve under the kitchen sink. We moved into the house in August 2024. I am amazed at how the Navicirc works! I was skeptical. The water heater works great too. It's an impressive piece of equipment. I hope it outlast me! 20 years?
Curious why you say don't get a tankless if you have Propane. I run 2 tankless systems - one for domestic and one for in-floor heat - on propane and they work great. There's a natural gas and propane option for some brands, or like this Navien it's one unit with different orifices and settings to change to accommodate either natural gas or propane.
I’m also curious. We run a Rinnai external in Northwest GA and ours has been great for the last 4 years. We do have a large jacuzzi bath we are about to remove which we noticed gets two cold spots in the flow when we occasionally fill it, but we have a hot tub and don’t want a large jacuzzi inside as well so it’s going… that’s been our only issue.
It works without a dedicated recirculation line, but you need either the Grundfos bypass valve or the Navicirc valve. On the latest models (A2) it works without doing any additional plumbing.
My company charges 6 k roughly , and they're junk. You have to flush if often, and your water must be treated as well. Warranties are terrible , tech support will not talk to you and most of us installers don't know what we're doing because there's no training. Stick with a direct fired storage tank , easier and cheaper in the long run , more reliable less head aches and more hot water
Makes sense, but we had an AquaStar(bought out by Bosch) tankless in Boise Idaho, thing lasted for 20+ YEARS!! My plumber was stunned. Just installed a Navien here in Monterey, CA. So far, so good.
I'm curious as well. We have tankless with propane, and obviously natural gas is less expensive, but we haven't seen any crazy propane use with our tankless. It seems pretty efficient.
It's ok to use it with propane, the propane conversion kit is included inside, along with the instruction on how to convert it. For the Navien units that is.
Recirc is a nice option that’s easy with the built-in pump on these units. Normal tankless units make “cold sandwiches” or take a while to warm up with low flow. These internal circulation models have a nice warm buffer to make sure hot water is always readily available, but you still need to wait 30-60 seconds for it to show up at your faucet. If it’s easy to put in a recirc loop (from furthest fixture to the recirc port) at the time of installation, you can have almost instant hot water, especially if you set up a pump schedule as this video shows you how to do. I’m actually really excited about this because a recirc loop is costly energy/wise, but being able to schedule it, and also to control temp deltas and pump run-times for firing on recirc makes this technology a lot more feasible to me.
@swagulous5097 Just had a 240a2 NG installed and came across this video setting up a schedule (plumber left the recirculation always on). I didn't see the need to have it heating the recirc line while everybody sleeps. Like this video, I set mine from 6am-9pm. Wish there was an easy way to see energy costs difference between having the recirc off, always on, and a schedule. The Navian replaced two 50gal electric tanks so I'm sure I'm saving a ton either way 😂.

This video is perfect, super simple, clear an easy to follow - Thanks!
I had NO IDEA "1 Day" was everyday same time. I was doing "7 day" and trying to program each day. PIA! Thank you Eric!
Why did you choose external recirculation? Wouldn’t it be internal? Thanks for the video.
Internal heats what inside the tank external heats what’s in the pipes
Appreciate this video my man
You bet
What about the bypass for this setup? Where and how is it installed.
Can you set it up for external recirculating with a external line without a external pump?

Can the external recirculation work with having to install the Navicirc valve?

Small houses only
What would be the total cost of implementing a Navian tankless for a house up north?

@@keaters123 My Bradford White 75 gallon storage lasted 5 years. My tankless in my other house is going on a decade, so theres that!
Why do you mention don’t use tankless if own propane?

It is included and very easy to change out.@@OCREPIPES
