in THE MAIN WALL
I have been research indirect hot water heaters and there seems to be a bunch of choices:



Glass lined

HDPE lined

Stainless 444

Stainless 316L

Stainless 316 Ti



Listed in increasing cost...



I am placing this in a oxygen barrier system off a conventional boiler copper heat exchanger boiler...

    Which Indirect

    Hi Radiohead,



    I'd go for the one which is most compatible with your water chemistry and is easy to flush/clean.

    How often?

    With SS indirect HW heater, how often would you suggest cleaning +/or flushing?  Do they actually need it?  I mean, depending upon water quality.  I am within NYC's water system.

    which Indirect

    Hi Jimbo,

     I have a Super Stor s/s indirect and I have to flush it once a month due to the amount of iron in my water. There are other indirects which have an access opening which would have made it easier to clean. I have to drain and refill mine two or three times to get most of the fine rust out.

    question

    Interesting as I was leaning towards the superstore..



    The triangle tube and the superstore are about the same price..  The Buderus (ubknown stainless) and the Viessman are 2x as expensive.  The Viessman is the Ti stainless.



    I am on well water, maybe I should do a whole house filter?



    Which water heater is easiest to flush?

    Not my first choice

    The Lochinvar is the cheapest $$$ with the least corrosion resistant stainless.



    The Lochinvar is made from the444L stainless steel.

    The easiest water heater to flush

    is a tankless! A filter is always a good idea. Mechanical filtration should always be first on line then followed by the proper equipment, neutralizer, softener, iron removal, ect.

    Remember what ever is left in your potable water eventually makes it to your wash machine. Always check for naturally high ppm of sodium, this will take stainless out in short order.

    Smart Tank

    After researching numerous tanks and possibilities, I selected the TT Smart-40, running hot using a mixing valve to reach a usable water temp for my DHW.  If need be, I will stick a hose into the inner tank and attach a small transfer pump to pull the water out.  Here in NYC, actually Staten Island, the only time the water seems sediment fouled is when they work on the main line out front or use the fire hydrant, so I don't know if a filter is necessary.
