I think that tank in tank design is just two nipples from the inner tank welded through the outer tank. Not unlike how the coils of a typical indirect exit the tank? I don't know of any other seals?

I'll bet many of the tank in tank have been filled and started incorrectly. I know I have😯

That design has been around what 30 years or more, there must be enough of them working well?

Debatable whether they outperform a coil type of the same square footage HX. They could be less scale prone.

Draining was the biggest issue, you had to plan for that.

A good observation, Ed.

Training is so available these days. I imagine every manufacturer of analyzers offers online and live training. Bacharach had excellent on site training and trainers.

The introduction of mod cons changed the game as far as owning an analyzer. At the very least you can check and confirm the numbers.

Assuming the meters are checked and calibrated as needed.

Drill and re-tap is the standard procedure for this.

you should be able to drill and re-tap thise vent ports. You may need to go a size larger

You can get 1/4 & 3/8 sizes

How's your water. Test for chlorides if you want a stainless tank.

I have had the best luck with glass lined steel tanks. This tank is sold under different brand names. Bock, Laars, now BW, Lochinvar.

Dual anodes, brass drain, large smooth coils, a nice pro quality tank.

How much hot water are you needing? 40- 50 gallons covers most homes, unless you nave a large soaking tub or other high load need?

Imagine how much water my service pipe leaked in the 10-12 years it was leaking underground.
