Need advice on replacing an old steam furnace

Perhaps the best place to start is with the book "We Got Steam Heat", which is available from the store on this web site. It is a very good introduction.

Steam heat is excellent, but it does have to be done correctly. The boiler (we don't call it a furnace, but that's OK) is sized according to the system to which it is attached, not -- as in many other systems -- to the heat loss of the building.

There are a number of makes of steam boilers, but the most important part of replacing a steam boiler -- in my view -- is the skill and knowledge of the installer. Even the best steam boiler will perform poorly if the installation isn't well done.

Hwangnyc, is this the same boiler you posted about with the water loss? Did you find out where the water is going? Did you find your old boiler having a hole that was the water loser?

It is a very good idea to correct the water losses before a new boiler is installed.
Any pictures of your existing installation??

Hello there,

I just found your site and signed up immediately. I learned already that automatic water feeders are a mixed bag. Thanks!

Turns out I have other questions, too many to list here.

Since 1981 I have lived in southern Wisconsin in a load-bearing masonry home built in 1925. It has the original low-pressure steam ARCO boiler and radiators with Trane No. 1 controls. The coal/stoker was converted to NG in the 50s. The thing doesn't have a Hartford loop (whatever that is), and the automatic shut-off switch dates from the 50s too. It's a giant tea kettle with a pilot light, burner and blow-off valve, nothing else.

While I have had it inspected occasionally, I never had a service call in 35 years until last New Year's Day when the paper-thin sight glass failed. This I took as a wake-up call so I'm talking to heating contractors about replacement.

I assume this is long overdue, but I only have to add a little water once a year and the thing works like a charm.

Any suggestions? Thanks again.

OK. Thanks.
