Since my 8 year old metal buffer tank leaked I'm considering replacing it with fiberglass or other non rusting material. It doesn't need water heating capability just storage. I don't want to spend $1200 for another Marathon water heater, that's what I have for the finishing tank. Any help appreciated, thanks
metal tank with periodic anode rod changes will be the cheapest route. there are Marathon storage tanks (non powered). not sure how much of a discount you get for the non-powered version relative to their powered brothers/sisters.
Did your metal buffer tank have an anode rod installed? If so, what was the condition of the anode rod when it started leaking? If your anode rod was completely consumed during that 8 year period, you may just need to replace with a similar tank and plan on inspecting and replacing the anode rod at a more frequent interval, say every 4 years.
A standard glass lined electric water heater like in the following link with periodic anode rod inspection/replacement will likely be your most cost effective solution for a buffer tank: https://www.homedepot.com/p/Rheem-P...ric-Tank-Water-Heater-XE50M06ST45U1/205810732
The tank did not have an anode so I'll be checking into a metal tank with an anode. Also will make sure to change the anode every 4-5 years just in case. Thanks for the info
i have gotten new anode rods from "waterheaterrescue dot com" I'd post a link but every time I do it, it takes days for my post to show up. without an anode rod, I'm surprised it even lasted a year or more
