It's guaranteed not to leak as well. Marathon is the only water heater with that warranty. Check their warranty. And the water temperature of a water heater isn't enough to do anything to the threads. Sounds like installer error.

If you can sweat pipe or solder copper as some people call it, you should be able to replace your water heaters with a friends help.

Here's a good tip. Make sure you have all the supplies you need, have a plan and start in the morning. I have seen several people DIY and they get stuck because they need 1 part after Home Depot closes. Start early and you can always run to the store if needed.

It doesn't say why, but we've been down that road before.


Interesting about the leaking though. You are right. For some reason I remember their slogan being "guaranteed not to rust" Who knows.

Don't know if $300 is reasonable since I installed my heater myself. It isn't all that difficult. You do need a 120V receptacle nearby for the heater's control circuitry. As for the gas line, I paid the gas company $100 to run it for me - just not something I wanted to mess with. In some places (though not here), it is illegal to work on gas lines unless you're licensed.

Replace your sacrificial anode and tanks will last much longer.

We had a Titan tankless in our previous house. It was less than three years old when it caught fire. Flames were coming out of the vents at the top. Cut off breaker and grabbed a fire extinguisher but it was too late, the heat caused the compression fittings on the water pipes to expand and the pipe burst outwards, twisting it behind the wall and putting out the fire.

New house has a tank heater. I like it.

I have the NR-98 DVC-NG since 2011 and it works fine and saves me money on NG. The newer units are now Condensing units and use PVC pipe for intake and Flew pipe NRC-98 by Noritz. I installed it myself for about $1250.Live in the Past or Live for the Future!

1. Is it time for new water heaters?
2. If so, are tankless recommended?
3. If tankless are recommended, what brand and type unit do you recommend?
4. If tankless are not recommended, what brand and type of unit do you recommend?

Thanks!

I ended up installing a single 85 gallon water heater and replumbed the house to accept hot water from the single heater. A few hours of work and I have saved tons of money by doing this. My propane gas bill used to be 100/month. Now I pay < 30/month for the electric Marathon 85 gallon.

Despite some other opinions expressed here, I love the tankless and would never go back.
That is totally dependent on the quality of the water. A lot of people are on well and it usually has a lot of mineral content.

I researched on-demand HWHs when it was possible we would have to install a second HWH only for the kitchen. Then I ditched this idea when a plumber was willing to jackhammer in a crawl space under a stairs to repair a below-slab hot water leak.

Consumer Reports did a study of tankless water heaters in October 2008 (http://www.consumerreports.org/cro/a...heaters-ov.htm). I believe efficiencies amd maintenance hassle have improved since then. Nevertheless installation costs for on-demand HWHs are significantly higher than for traditional HWHs.

What I liked about the Noritz MRC661-OD is this (www.noritz.com/products/nrc661/):
It is made for outdoor use.
There is no vent pipe. (It uses condensing technology.)
It is relatively small (7" deep, 14" wide, 21" tall) and hangs on a wall (36 lbs.).
It can be supplied with a 1/2" gas line. (There are other gas pipe requirements.)
The energy factor is 0.91.
Someone else was going to pay for the installation!
Less hassle and less costly for the someone else than demo'ing and rebuilding half the stairs and moving us out for half a week.


Since not having to consider a second HWH, I have begun to think about calc build-up on plumbing fixtures. I am going to try out an idea I read about for the recommended annual cleaning of a Noritz on-demand gas heater: A pump is immersed in a bucked and pumps vinegar through the HWH and drains back into the bucket -- for an hour. I intend to pump vinegar through our kitchen sink hose and nozzle which is starting to switch hard between full and spray. We'll see how much this improves the situation.
