Tankless Water Heaters
Posted on 6/25/25 at 6:30 pm
Posted on 6/25/25 at 6:30 pm
I'm looking into swapping out my gas water heaters (2 - 40 gal.) for tankless water heaters. I've spoken to 2 different plumbers and both said they aren't a fan. 1 plumber said I would also need to add a pump under the sink and in the master bath so that I get instant how water.
Does anyone have experience with the tankless water heater and do you like it? Any issues with the tankless that you've experienced?
Also, did you have to install a separate pump? Thanks.

Do it, best decision I ever made other than emergency generator

Do it, best decision I ever made other than emergency generator, and we don't have a pump.

I've heard more experts speak against them

What was so bad about waiting 30 seconds for water to heat up?
Is there another benefit?

How about endless hot water and not waiting for the gas or electric tank to heat back up?

That would require the water heater to run constantly would it not? Or would you put the pump on a timer?

I have a tankless with a pump in my bathroom. My bathroom is the furthest away from the heater, so they recommended the pump. It just help to keep some warm water in the line. I can hear it queef as I call t from the bathroom once in a while. We can take a shower in all three of the bathrooms with no issues.

I self-installed a Rinnai 20 months ago. It has a built-in recirculation pump in the heater. I had to buy a Wi-Fi module , thermal bypass valve, and I bought a push button.
The thermal bypass valve is installed under the farthest sink (master) from the water heater. The valve allows the water heater to return hot water via the cold water line, back to the water heater. This allows for recirculating without a dedicated return line. The wi-fi module allows me to control the water heater via their app, or via the push button. The app allows me to schedule the recirculating pump to begin making hot water when I want. So, at 6:15 AM, it starts recirculating hot water. Without the pump running, it takes 70 seconds to get hot water to the master shower. With the pump running it takes 10 seconds to get hot water to the master shower. The push button is next to my master shower. It starts the recirculation pump when pushed. I use it when I shower off the schedule.
So far, I dig it. I did the first flush last September, going to do another this September. I would have kept a tanked if I had the choice, but the idiot that finished my basement, trapped the tanked in a closet by building a door that is too narrow to remove the tank and replace.

The pump isn't necessary.

I replaced 2 50 gallons tanks with 1 tankless. Love it.

I think having hot water in the system circulating constantly will negate some of the efficiency of the system, so I would not opt for the pump. However, the prospect of unlimited hot water around the holidays when you have a house full of people is intriguing.
Also, be aware that there aid some maintenance that you have to do periodically on these units for them to operate correctly. Most people have a plumber flush the unit periodically.

My only regret is not ditching the beast electric one that's on the main side of the house when I had the chance. If I did that now, it would be a permanent attic fixture.
On our master suite side, we have a gas tank less that's mounted outside. Never had a hot water issue and wait time is about 30 seconds.

I love mine. No pumps either. Takes a little bit for hot water but you get use to it. Super efficient
Some of them let you use pvc as the vent which is great for DIY. My Takagi been going strong
