A: Warwick Rhode Island USA . I have been to the factory and seen them made. I think they do now offer and import but these are the domestic versions.

A: That really depends on your system as they are all different. Some systems are designed and installed to make this easy. They, like mine, have an isolation valve that allows you to close off the expansion tank. With those you can then unscrew the old tank and screw in the new one. However, most are not set up with maintenance in mind. So, you need to take significant water out of the system before you can replace the tank. Then you need to replace the water and more importantly purge out all the air. I don’t find this daunting but then again, I have done it before. The answer to your question depends on your system and your knowledge relative to the principles of a hydronic heating system. Let me add if are unfamiliar with how these systems work and unscrew the old tank water is going to come out under pressure, and that water could be dangerously hot if the system is up to temperature. If you are unfamiliar with how to change a tank, I would suggest you contact a local qualified licensed plumber. Chris 978 651 3301
