in THE MAIN WALL
I didn't know who made it because the bottom was covered with insulation. It was in a single zone monoflow system suspended between the joists. Never had a problem with it and the homeowner commented on the warm spot in the kitchen floor. I assume that when too much air is trapped, the excess will go to the first radiator where it can be manually bled.

    Thrush air tank

    Yesterday we removed this one. It is a steel expansion tank, but the supply water flows through it.

    Nice job Bill.

    The Thrush tank I've never seen, but the Top performer....thats a different story. I've seen too many of those, and most were replacements for the original install.

    Heavy mothers, and quite a chore to move after the stone lining is saturated.Shoot, they're heavy when they're not sturated too. Hope they've improved since the first ones went in. Chris

    Huh?

    Never saw one of those before. I guess the idea is that if there is air in the system it will get trapped in the tank. Being an expansion tank, if it gets full you'll need to drain it, but not too much? And if there is too much air you'll have to let some out, but not all of it? It doesn't have a float to let out excess air does it?

    Hi Bill,

    Is that a sight window on the end in the second picture? Any plugs or fittings other than the two on the ends?

    top performers

    These are popular at one of the supply houses I deal with, however I have not used one yet. I have been using mostly Megastor lately.

    I am not really sure what the big advantage to these water heaters are. I can understand the brochure, and how the mass of the stone lining helps extend the first hour rating, but I am not sure if it is really worth the back ache!!!!

    Nice job!

    Ron,

    Ron, you mean on the end of the tank about 1/3 of the way up? That is a coin vent behind a metal tab that must protect the coin vent? I guess. No literature

    Seen one too

    They make sense. I suspect when the big old boilers went out in early sixties and their built in low velocity air seperation chambers, Thrush figured why not just do the same thing in the piping and add the compression tank too. Seems to be one of those common sense ideas that got lost over the years.
