We have an old farmhouse, too, and did a major renovation of the kitchen as well. There was one big radiator in the kitchen, about 2 feet high and almost 4 feet long. With two exterior walls we needed about 16 feet of baseboard unit to equal the heat output of that cast iron beast. With the custom kitchen we had designed for us, there was only about 1 foot of wall space that didn't have cabinets, and that was right by the door. We solved the problem by putting in a radiant heat system in the floor. There are several companies that sell the necessary hardware. I bought mine from Maxxon. See www.maxxon.com. The hot water flows through cross-linked polyethelyne tubing and transfers the heat into a 2 inch thick mortar bed. We used ceramic tile as the floor covering. It's a good bit more work and $$, but there is nothing like a warm floor under bare feet on a cold winter day. Food for thought. Good luck.
