Steam Radiator in Hot Water System


We have one radiator in the house that is a steam type radiator but the house is a hot water system. This radiator has a vent valve (water valve) halfway up the radiator instead of on the top. Because of this, only half the radiator heats up. I like the radiator and don't want to replace it and am looking for advice on how to bleed the air.
Thanks.

Your semi hosed.

It should have been converted to a water rad.

Many of those rads. have a flat spot near the top, above where the steam vent is. that is where it is drilled and then tapped for a bleeder to be installed.

if you want to attempt this your self. Wait till winter is over.
Then do it in the spring. So that if you crack the rad. You don't have to do without heat.

Before you start this project verify the radiator is connected with top nipple ports. All sections should be touching each other.

Well, there is no flat spot at the top to tap a bleeder and while the fins "touch" the core is only connected at the bottom. So, perhaps I am fully hosed.

If I attached an external elbow and temporarily extended the height of the vent above the top would this allow me to fill it?

Thanks for all the help.

Nope.

The air will stay in the sections.
