H.S. Tarm is one brand... not sure if they are nationwide though. There should be several brands available.

Do a search for Wood Master wood stoves. On their website is a dealer locator. Enter your zip code to find a dealer near you. They have wood boiler systems for all sizes of homes. There are many brands like them.
