We have two for that reason, just checking. Are they linked together? If not, I’d reroute lines and go down to one.
You're going to replace two water heaters because the pressure relief valve is leaking on one? Just replace the valve, they go bad quite often.
They are linked together in the sense that every hot water faucet in the house draws from both tanks...is that what you are asking?
Gonna DIY?Well...I also want to stay ahead of the curve a bit...I looked at the "fine print" on both water heaters last night and one was installed in 1999 and the other in 2000.
Gonna DIY?
If they are 20 years old I wonder if they have ever been drained to get rid of lime build up. I've done that on ours before. It may get rid of your pressure valve issue.
On top of all of that I know of a couple people who have had tankless ones freeze up and burst in the winter. I don't think I'd ever go that route personally.
Mine is 20yrs old and still running well. When it’s timecto replace, will stick with the tank.
A few people I have talked to suggested that if they have worked for 20 years then I should consider myself lucky and change them out? I hate doing that if I don't have to but I also see their point...how much longer can I expect them to last?
As someone getting ready to swap out my 15+ yo water heater soon, if you have not drained or done any recent maintenance, I would recommend not starting now. I was emphatically told not to drain mine (it was here when we bought the house and they did zero maintenance), or really do anything to it until I replace it because that could cause immediate failure.
Exactly, don’t start now. I did that and it started leaking after that and had to replace it.
Don't do a tankless. They have a shorter lifespan, need annual maintenance, and most importantly, they require a large amount of flow to generate heat.
That last point means if you wan't just a little hot water, ie lukewarm to wash hands, it is darn near impossible.
Financially they never make their extra cost up, as they typically need replaced before they recoup their initial cost.
Got some quotes and the best quote was from a local (Cedar Rapids) business that said they would replace one water heater for $970 and would knock $200 off the second water heater if I decided to replace both. This company uses A.0. Smith products (never heard of them to be honest). This included installation of the new water heaters and the removal and throw away of the old water heaters. Reasonable? The company was referred to me by a couple of different people who used them for geothermal heating/cooling systems.
I've also been told the components inside a tankless don't handle any type of hard water. So the lines inside could get holes in them and start leaking. Plumber recommenced a reverse osmosis system filtering the water before it hits the water heater.
