The New HS Tarm Bonus Plus Wood Boiler

Coming this fall we will be introducing a new wood boiler to our line-up, the HS Tarm Bonus Plus. This will be a great boiler for someone looking for a compact, easy to use, well priced boiler. We are calling this the little sibling of our popular HS Tarm Solo Innova boiler. It is well suited for well insulated small to mid sized homes. This boiler will also work great with a single 400 or 300 gallon tank which simplifies piping and saves space.
