Tankless water heaters?

[Smawgunner2]

Our new house had a kitchen and full bath upstairs. We ripped out the kitchen. It was part of a new addition to the home and a dedicated 40 gallon electric hot water tank was installed. Our electric bill since we don’t have gas was 450 bucks last month. Plus the tank is 16 years old. Would replacing with a tankless save money in the long run? I’ve heard horror stories about tankless….temp fluctuations, not hot enough, maintenance etc. Any have experience with these?

We put a Navien tank less in when we built new home in 2020. Extremely satisfied with this unit. Unlimited hot water on demand. Zero issues at all with it. Would highly recommend.

I own two Rinnai R53 tankless water heaters… one in the house, one in my shop. Both have been in service since 2006. Knock on wood… I’ve not had a lick of trouble with them. Honestly, I think they’re great. Mine do run on propane though, not electric.

Ppropane here as well.

We install them all the time. As long as you do you maintenance you should not have an issue. Just replacing the existing tank would help some on the power bill. To get 16 years out of a tank is impressive. Usually the bottoms rust around 10-12

Care to expand on the maintenance needed?

Propane or Natural Gas yes do it.

Electric - I do not recommend. I have 2. One in the cabin and one in the barn. Both do well enough to make do.

Winter time temps keep them from getting the water hot enough. I am in Tennessee. Our ground water is quite a bit warmer to start with.

We have one and it runs on natural gas. Very cost effective however, it takes a few minutes for the hot water to reach the faucet. I let the shower run in the mornings while I brush my teeth….by the time I’m done, the water is warm enough to get in, after another minute, it’s hot. Never timed it but I’d say 2-3 minutes for full hot water.

On the maintenance side its pretty simple. All your doing is descaling the tanks. They make a solution thats at any box store. 2 5 gal buckets 2 short hoses and a small transfer pump. Solution goes in and does its thing and comes out. Not saying they are all the same but the ones we install have the connections all ready on them.

Yep, exactly this. ^^^

It’s pretty easy to do. I’ve done it myself a couple of times. But anymore, I just ask my HVAC guy to add it to the list when he’s servicing my furnace system.
