About time to replace our water heater. Any recs on tanked vs tankless based on your experience? We have a gas system. Also, is this a diy job or plumber? Any recs on a plumber to do this in BR?

Tankless was 2x more than conventional. I was told tankless has an endless supply of hot water but it isn't as hot as tanked.

Just what I heard. I chose tanked.

Either can be set to whatever temp you want. Tankless has a limit of X gpm at Y temp.

Tankless is superior in every way except price and a slight delay in sending hot water to larger houses.

I have a 40 gallon gas tank water heater. It's only me and Mrs so we never run out of hot water. I did the math on installing a tankless. The added cost of the tankless install had me saving money on my gas bill starting in 15 years. I installed another tank water heater.

We had tankless in our last house, we're building now and putting in tankless. Don't need it all the time, but when you want unlimited supply it's nice to have. I have held a sick and screaming child in a warm shower for hours so he could get some sleep, I've been miserably hungover and spent some extended time in the shower too.

At this point tank type heaters cost about 600 dollars for the plumber to buy opposed to about 350 pre covid. The installed cost should be getting closer. Get a tankless if you have the gas line to support it and get a descaling system and you shouldn't have to worry about it for a long time.

Tankless without hesitation.

Not a DIY job.

Why do you say it's time to replace the water heater? Is it not functioning properly? There may be a simpler solution than replacing it.

We have a tankless and we love it. You do have to wait a second or two for the water to get hot but once its hot it stays hot.

I'm in the same boat... my old tank heater seems to be on its last legs. Seriously considering tankless.

Who would y'all recomend in the BR area to purchase from and do the install?

as previously mentioned, if you currently have a gas tank water heat, may not be a plug and play, may need to increase the gas supply line by the meter to support the tankless

An additional drawback is if the power goes out you have no hot water. That said, I love tankless.

I assume you can't just go run out there with a lighter and fire that sucker up like the old tank water heaters

Mine is as hot or hotter than my old tank. There is a limit on how hot they will allow you to set them from the factory. Mine you get up to 120degrees and then you have to hold down the up button until it starts going up again.
If I remember correctly, mine goes up to 145 or 150. It's set on 135.

Tankless requires a 4 inch exhaust pipe while Tanks have a 3 inch. That difference was the reason we couldn’t upgrade to tankless.

It depends on the tankless you buy. If it’s a condensing tankless-you can vent it with solid core pvc. The Naviens I install are vented with a 2” Pvc pipe. The Rheem condensing is the same. The Noritz condensing tankless is vented with a 3” Pvc pipe. If you don’t get a condensing unit-you’ll have to vent it with the 4” stainless piping and that is expensive.
