Gravity hot water heat

radiantking

I need to brush up on converting a gravity

Gas fired heating system. Which one of Dan's

Books should I read too refresh my memory.

There are two supply's and two returns coming

Off the existing boiler. One stat in the house.

Also have to add a separate baseboard heat zone to four season room.

Classic Hydronics

I think classic hydronics has the most info on conversions.

One of the gurus on here posted some circulator sizing info in resources. I can't seem to find it right now.

Gravity

Thank you Carl, I have that book. And will read.

This is a closed system, with expansion tank in the basement

Home owner has told me that radiators on the second floor have stopped

Heating several years back. I think I will need to figure out what is causing this

Prior to installing new system. Radiators are piped at top and bottom on same side

With vent at opposite side. Any thoughts would be appreciated.

look in attic

You may be surprised. Expansion tank in basement was probably added along with gas burner.
