What is this?

Jeff_53

While this 'mystery part' looks interesting, I'm curious about the bass drum sitting next to it? Are there more
old drums up there?

Anthony Menafro

Can anyone tell me about this?

I'm installing a new hot water boiler and found this in the attic. The pipe going up goes to a gravity tank and the pipe to the right goes to two dead rads. All the rads in this house are the old beautifully sculpted rads and am happy to keep them. I wanted to know if this should be disconnected and install the expansion tank at the boiler?
Thanks for your help, Anthony
The lower fitting says Patented Great Britain MCH 28 1897
other patents pending. The upper fitting that looks like a flying saucer says Honeywell NO 1 System.

Old drums

Yes. There is a whole drum set and several guitars. The owner's son plays them with his friends(you know, the old BAND scene)

Anyone

Does anyone have any idea what it's function is?Anthony

sure do,

its a honeywell heat generator,,watch out, its got alot of mercury in it..it made it possible to raise the temperature in a hot water system to approaching the boiling point and still not allowing the water to flash into steam at the top of the system where static pressure would be lowest..this made water move quicker cause its density changed at the higher temperature..i have one proudly displayed in my library room..don't touch it..its hurting nothing,,and heads up, all it took was someone rapidly filling the system (filling to fast), and the mercury will have been distributed about the whole houses piping system...and you'll only know when the little balls go running around the floor and your three rooms away from the generator..ask me how i learned that- hehe.

it might be extremely old but it still works n serves it purpose. personally if it were my system id remove the old tank, cap it and install an expansion tank in boiler room. if u decide to do so, make sure to size tank correctly, gravitly systems hold a lot of water so theres a lot of expansion!! good luck

I Have One as Well

I am the proud caretaker of a Honeywell Heat Generator as well thanks to the generosity of our host, Mr. Dan Holohan.

You can read more about the Heat Generator if you click on the Library link to the left.

If I understand correctly, Mr. Gill, it was you who provided Dan with the patent information, correct?

It pays to wander off The Wall.

Gravity system

This system is only piped in 1 1/4 throughout the house. The top floor rads (2) have been capped and the attic in which it sits is very cold. I don't like the idea of leaving any piping containing water given this situation. I prefer removing these fittings rather than having a freeze up problem later. This attic has a bad draft and it's not even cold here yet(N.J.) I have every intention of removing this and I will be extremely careful in doing so. Thank you guys for your very good insight and leading me to where you've already been.Anthony
