can i remove a honeywell heat generator?

[Deleted User]

move the gravity hot water expansion tank in the attic to be able to finish the space off. the tank is still in service and there is a honeywell heat generator in the basement. my question is, can i hook in a diaphram compression tank to the inlet pipe of the the heat generator? thereby removing the generator and then remove the expansion tank. ( both i have to admit will end up in my personal museum). my concern is that the diaphram tank would not aid in moving the water around as good as the generator did. i understand from Dan's book HOW COME that it would allow as much as 10 psi at the system top. im assuming that means i would see a gauge pressure of @18 for the height of the water plus another 10 psi from the honeywell device when the boiler was running? any help on this project would be appreciated. can i do this removal without screwing up the gravity system?

At what temperature

are they running it now, Gerry?

the aqua stat is set to open

at 200 degrees.

DanHolohan

You can remove it

but bring a BIG compression tank to allow for all that water.

thanks Dan, another question tho

the attic expansion tank is exactly set up like page 13 of HOW COME. my question is, if the heat generator was to isolate the x-tank from the pressured piping then how did this do it piped with both a supply and return pipe? i would have thought a set up with only one pipe as the supply and return would be needed? this things really confusing. makes me respect my elders even more. they got me baffled by something with no moving parts. and they did it from the grave....wait till i see them!!!!

DanHolohan

That makes no sense

The Honeywell book I have from around 1905 shows it only with the one connection, and it shows it several times that way. Could have been a mistake. They were just like us, only human.

so its possible then

that since the tank in the attic is visible and has both bottom pipes that its possible this thing has been in the system for 80 or a hundred years and has been doing nothing at all? of course someone may have installed a replacement x-tank and put it in wrong, i suppose.

last question Dan, i ALMOST promise

concering the heat generator, i understand how the water blows past the mercury as the pressure builds to a predetermined level... is the reason the device is lifted off the floor due to measuring down from the attic tank a certain distance and that was where it had to be placed in order for the water in the pipe leading to the tank to only hold a certain height of water, and when the boiler cooled off, the water higher than this point would then weigh enough to overcome the mercury in reverse, to get back into the system? i think i said that right.

What will they say about us?

As far as piping, we are so inferior to them. So much attention to detail. In my opinion, we "overcontrol" sometimes. The neighbor with the gravity system and millivolt burner is The dude" in times of crisis! Jus ramblin' ...... Love your site!




ADIOS, Tom

DanHolohan

Sure

that's possible.

DanHolohan

There was no requirement

to set it off the floor. Dealer's choice.

DanHolohan

Amen

and thanks!

Don't forget

to recycle the mercury. We save all of our mercury bulb thermostats and aquastats and #1 droppings and drop them off at a local wholesaler who is licensed to receive, store and ship mercury.

Keeps it out of the potable water supply.
