Should attic water heaters be replaced before they have issues? Mine are going on 14 years and havent had any issues but i was thinking I should get them replaced. I am obviously concerned about water heater issues in my attic.

As a general rule, a tank style water heater will last, on average, 8 to 12 years. If your water heater is pushing the 10-year mark, there's a good chance it's time to replace the unit, and you may want to consider a tankless model.

Per Google

quote:

Based on the manufacturer's suggested service life, the life expectancy of a water heater is about 8 to 12 years. That varies with the location and design of the unit, quality of installation, maintenance schedule and water quality.

Mine have never been serviced. What am i looking at if they fail? They have a pan with a drain under them.

Mine is a 43 years old monkey wards...make sure the anodes are replaced regularly and flush it out every now and again.

Ours is from 1987. Should probably replace it soon

Does it have a drip pan and a drip pan discharge line ending outside, if so let it roll till it stops working or starts leaking. Blow out that drip pan drain line and make sure it’s not full of dirt dobbers

Just replaced mine. Installed when house was built in 1956, sixty four year old American made hot water heater, older than everyone on this board (almost).

I just want to know what happens when one fails in an attic. Is it going to collapse all the ceiling drywall or run nicely out the pan drain, lol.

Its a 1 inch pvc pipe straight to the outside. I have blown this out regularly. Pan is probably 4 or 5 inches deep.

YES.

I will never have a water heater in the attic again. My attic was well insulated, but many years back when it was 15 degrees for like 3 days, a water line burst while we were at work. We got a call from our neighbors that water was pouring out of the house at the slab. By the time I got home to shut the water off, that single burst water line had done $150k of damage to the house. Remediation started the next day and we were living in hotels for five months.

It was exactly the same remediation as a flood. Below about 3-4 feet, everything was demolished down to studs and slab and rebuilt. In three rooms closest to the water heater, all walls, floors, and ceiling were replaced. Two rooms required no ceiling demo because it was already on the floor when I got home. I could look up and see the underside of the roof decking. All of the insulation in the attic had to be pulled out and replaced.

If something happens and it overflows the drain pan in the attic, it can wreck your house. Granted, the same kind of massive water leak can happen with any water heater. At least there's more protection from the elements inside the house and you can put them in a utility room or a mud room that drains into a garage or outside.

from the pictures of the sizes, looks like a no brainer...how did the technology get so good to the small box thing compared to the old tank? I have no clue about any of it..

Test the drip pan with a couple of gallons of water. If it doesnt leak, you should be ok. I changed one out Saturday that was 20 y/o. The pan did its job.

I actually hate to replace old shite in my house because there's a 99% chance the new thing is going to be shittier. My oven was made in 1976 and will still cook a mean frozen pizza

Mine just busted about 3 months ago after 16 years . Went tankless on this one . Scared shite out of me when it did . Busted all down the seam but pipe to outside saved a lot of damage but better to replace now than when you HAVE to with possible damage

Can you replace two tank units with one tankless system?

You're exactly right, shite isn't built nearly as good as it was back in the day. had a friend just replace a fridge that was 8 years old. Just got a new one , rather than pay 100 bucks to have somebody come out, labor, new part, whatever..
