One thing I like about the coil-type tanks is that the hotter boiler fluid is encased in the water it is heating. This reduces heat loss off the tank when compared to a tank-in-tank version. I also would not use a fin-tube heat exchanger in a water heater for the reason hot rod mentioned. I also agree that it is a good idea to look for a tank with a good access hole for cleaning. As a side note, the Crown/Burnham stainless 120g tanks have more surface area on the coil than a Vitocell V 300.

Favorite indirect

Just wondering what type of indirect water heaters you all favor. What about designs, tank in a tank, or coil HX?

have provided the best performance and least amount of failures. They handle hard water conditions much better than a finned coil type HX, from my experience.

Next would be a large diameter coil type HX, like the Viessmann, Buderus, and I believe Bradford White has a new line of large diameter, un-finned glass lined tanks.

Buderus and Viessmann have large cleanouts to check conditions from time to time.
