Advice on Indirect Tank - Dunkirk Artesian

Options
Looking to install a modcon with a indirect domestic hot water tank. In my research I came accross the Dunkirk Artesian tank. It looks like they surround the domestic coil with boiler water. This appears to have some interesting attributes including longer life of the tank and good heat recovery. Anyone have any comments on this? Are there similar approaches out there with competing products?

    Not new tech just new package

    the old side arms so many folks hated were same idea. I feel the volume side for the domestic water allows for room for the crud in the water to go somewhere besides clogging the flow pipes. The idea of an indirect in my mind is to have a highway of wide lanes for the water with the most contaminants, that being the domestic water. The boiler water actually has less contaminates because it is the same water recycled back and forth through the boiler and coil.

    Interesting Perspective

    That is interesting, never thought of that. My old boiler has an abandoned side arm that was replace with a direct fired unit. Too much crud inside the water pipe?

    I also saw that the Ergomax is essentially the same idea, although the use of a buffer tank might be beneficial no? How is this different from a tank-less water heater? Would those suffer the same fate?

    Tankless heaters are subject to

    water quality issues. If the side arm did not work out why not use a standard indirect water heater? The large capacity of water on the boiler side will also require a larger expansion tank.
