I have had a long sought after 502 for a year now and loved it. Now I have a 530 and I like it better. They both heat about the same but the 530 tank dose not get hot like the 502. The 530 cleans up very easy no paint to worry about. The only con I can find so far is the height so may tip over if bumped but the tank stays cool and I do not like a hot tank of gas. Can anyone tell me the BTU of each? So far it takes about 20 min to get 10 cups of coffee done.
