I love old cast iron radiators. Can you think of another product that: 1.) Will last forever with a modicum of care; 2.) Is the best product of its kind; 3.) Is a work of art Here's one that I refinished on Sunday and hauled into the greenhouse. I was delighted, upon cleaning and painting, to see the lion head cast into the design on the columns. This is male-oriented radiant heat. You're not supposed to mix ci rads and copper finned baseboard on the same zone, but when the 24 feet of finned tube couldn't cut it, I reverted to the tried-and-true approach. When I bought the place, the greenhouse was heated with three small, ci rads which I appropriated for other uses. I thought the new baseboards would suffice. Eventually I'll probably paint the baseboards black, too; they're pretty worthless as heaters, but maybe they'll absorb some solar radiation in the summer that I can pump back into my system.
