50 Gallon Indirect Hot Water Tank Manufacture Recommendations?

PilotPat24

Hello,

Does anyone have a preference or recommendation for a 50 Gallon Indirect Hot Water Tank?

Thanks,

Pat

Lochinvar SIT050 stainless tank or Viessmann stainless
IMHO

If you go with stainless make sure the chlorides in your water are less than the manufacturer spec.

Thanks for the feedback guys. How do you go about getting your water tested for chloride levels? For what it's worth, below is the whole house water filter I have on the house.

Hi, If you are on a municipal system, they will have a water quality report for you. Probably online.

Thanks! I actually called my water supplier and they are going to come by next week to test the water. I will update you with the results.

I prefer glass lined tanks. They can handle most any water condition. Keeping the anode in tact is the key to long life in glass lined tanks, either fired or indirect.

or use a powered anode

I like the Bradford white tanks. 3 anodes and a great warranty.

The welds are often blamed for stainless tank failure when in fact the chlorides attack the welds more so than the stainless itself. Dave Davis of HTP explained that issue many years ago when I visited HTP factory. Back early in the SuperStor days
His dad had a welding division of HTP, used to be in the other side of the HTP building, so he knew welding metallurgy fairly well. The metal properties change at the welds, so different shield gases, wire composition, pickling after the weld, etc. have been tried.

George at HeatFlo knows stainless fabrication well, if you get a chance to chat with him.

That is one reason you see all the different alloys of stainless being used over the years 304, 316, 409, 316AL and Ti stabilized, etc. Trying to find a stainless the handles all the water treatment chemicals, welds easily, handles thermal expansion...

And the water treatment chemicals have changed over the years. Chloramines in place of chlorine for example. Peroxide, Iodine, etc.

One brand out of Canada used to use a different stainless for the coil and tank.
