Public water – no electrical going to it…

It looks like the fill tank for an open hydronic heating system. Any signs of old radiators in the home?

The old radiators are hooked up to a new boiler…


So yes .. there are radiators

Saying that thou... the newer boiler... is on the other side of the house...

This old house was 9000 sq ft. with 6 fireplaces and three chimneys...

The boiler is hooked up to a different chimney... on the other side of the building...

But I think your guess may be correct... good thought..

I think Charles hit the nail on the head. Last clue that it's an expansion tank for an (old) open system would be if it's higher than any other component in the house. I wonder where the overfolw drain went to?

It was for sure higher than any other component in the house…


Not sure where the overflow went to...

It was one of the most interesting homes I have looked at to date... and the biggest... I was there for over 6 hours... ![icon_smile.gif](upload://b6iczyK1ETUUqRUc4PAkX83GF2O.gif)

My guess is that it is the same principle as was done down here, but with a different source of energy.


They used to put the water tanks in the attic or on the roofs, and paint them black.

They were the first "solar" water heaters.

Up there, instead of "solar" heating the tank, the heat from the chimney would heat the tank.

Viola, hot water (okay, warm water, but at least it was not cold water).

That’s was what my first guess was…


Hot (o.k. warm) water tank...
