This is Unusual

Sorry to disagree Big Ed, but did you look at the rest of the photos? Nameplate by Burnhamm, clearly labeled "Electric Steam Radiator"--not something made up by a building super...

Can't disagree about its bomb potential however. 2,250 watts and what certainly looks like a 25" high four-tube Burnham "Slenderized" rad. That's about 7,677 btu in a radiator capable of liberating about 3,500 btu @ 1psi steam in a 70F room. If I've done my calculations right, it could hit about 280F in a 70F room at about 50psi. Definite bomb potential!

Cast Iron Electric Steam Radiator by Burnham. Any idea when this thing was made?

Maybe sometime between 1972 and 1974? In all seriousness I've seen other brands from the 1930's that were stand alone electric radiators.

Way older then that

It was made before you needed UL aproval. Dam thing is a bomb. Looks like it only has a heating elament and a vent. Some super made it up for when a tenant cried "MORE STEEM". He would wheel up one of those claymores and problem solved.

Funny thing Mike

I was at this ladies house last week, in her basement out of the corner of my eye I saw something very similar.
Like Ed I just figured it was "made-up" so I ignored-it.
I have to go back this week so I`ll check-it out more closely.

Well I looked,

it appears to be a made-up unit, no ID plate.
Very small CI rad with 1K electric element screwed-in the bottom.
No thermostat or vent anywhere, only petcock drain, definitely BOMB potential!
I told her never to try using that, so she gave it to me.

How many sq.ft. EDR in the radiator? 1kw isn't that much and, UL aside, it could be intrinsically safe.

Didn`t carry out

yet Mike(alot of crap in basement & was alone), but I told her I would send the boys and take-it out in the next few days.
Want a pic when I get it?

This is truely a Burnham product I have seen one floating around the Burnham offices, the guy's in tech can supply you more info on it, I belive it was Jon, that you would want to speak to,

This is similar...

... to the Clow Gasteam, which used gas as the heat source. Dan has info on it in the library, I believe. That has an air vent which prolly helped to keep it from blowing up. Asphyxiation from the unvented model was a different consideration.

The Clow

The Clows was a neat, water filled radiators with a gas burner under it. It had a few inches of water fill, a steam vent and a diaphragm regulator. When the pressure went up to about 15 psi, it would block the gas flow down to a trickle, just to keep the burner lit. There was a solder plug just for safety.

Had one here in the shop for years. Screwed a pressure guage onto it to try it one day. It simmered for about ten minutes, then the pressure went from zero to about 90 psi in the two seconds it took to shut the gas off.

I guess the regulator was slow reswponding.

They had vented and unvented models. In the vented ones, 3/4 of the heatwent up the flue.

Sure. Photos are always nice
