What should I expect to pay for a replacement water heater?

- normal 40 galllon upright heater
- in attic, but steps leading to it (not ladder)
- screwed flex lines for supply
-already drained and partially disconnected

Not emergency work, but I want to get it replaced soon.

Yeah I was going to say, no one is doing it hourly plus parts anymore for the most part. I'm seeing $2k-3k range generally speaking.

$2500 to $3200.

You could get the heater and diy. It's really not hard especially if using flex lines

Just did a 50 gallon replacement:

Got two prices, 40 gallon at $2,000 and 50 gallon at $2,300

Went with the 50 gallon for a couple reasons. The company for the 50 gallon provided a professional series Rheem with an expansion tank, and replaced/ cleaned up in and out lines. The other company did not provide these items and services in their quote.

DO NOT BUY FROM BIG BOX STORE...unless budget is a major concern.

Whichever you choose to do make sure the tank you get is the simplest function in terms of repair parts being readily available. I say this because the tank we replaced had a thermopile type unit, not thermo couple, and the part was $700 not including labor. It was 11 years old. Natural Gas.

If you are gonna spend $3000 for a conventional water heater, spend $6000 and have an on demand put in your attic. You will not regret it.

I went ahead and upgraded from 40gal to 50gal. The quote came in at $2450, so I went ahead and agreed….they will install tomorrow.


Doing it myself was tempting…..but I am getting to the age where I don’t need to be wrestling around with a water heater in the attic any more!

I appreciate y’all’s feedback!

I am pretty handy and do most DIY, but messing with plumbing and natural gas in the attic was not on my list of things I wanted to tackle, buy new tools for, and break my back hauling the old one out of the attic and back up.

I've seen it mentioned here and many other places, but why do they put them in attics these days? My old house built in the late 60s has it in the basement/garage, and the townhouse we bought new in 2004 had it in the garage as well. Seems like more of a PITA to install in the first place, and even worse to replace up in an attic.

We had ours replaced a couple of years ago in Birmingham for around $1,200. Upgraded from a 40 gal to a 50 gal tank, natural gas, and he did the replacement and haul off for that price.

Can't give up them square inches of floor space baw.

Utility rooms aren't a thing anymore. People want laundry rooms which are their own luxury spaces. Can't be polluting that vibe with water heaters and air handlers and shite like that.

Honestly, if mine had been downstairs, I would have replaced myself….and wouldn’t have to deal with repainting my ceiling now!

As Downshift says, they put them in the attic just to save floor space…same with central A/C units. If you think about it, two water heaters and a central a/c unit would require the floorspace of a small bedroom.

In the last 3 years I've replaced 2 of mine myself with the help of my son.

the only hard part is getting the new up into the attic and into place.

Takes 30 min to drain the old one.
but the copper lines and install shark bite water heater lines.
Get the new one in place and connect the lines
connect gas line and light.

its a 2 hour job at the most and most of that is the draining of the old one.
