Yes it was a baseboard radiator. It was completely our fault. We run our wood stove whenever we are home. So Friday night-Saturday I was running the stove. The pipe that burst was on the other side of the house from the wood stove. The room the wood stove was in was 75 or so, but the heat doesn't make it to that room. Basically I was attempting to save $10 or whatever in oil and ended up costing myself $1500 in repairs. Next time it gets that cold I'm just going to let the oil run.
