“1 year ago I started model S30 on 1-6-21 and after a few days of learning how to operate this boiler, it is working wonderfully. I replaced a 38 year old Tarm OT30 and this new boiler uses about 25% less wood than the old boiler. I am very satisfied with the operation of this new boiler and thermal storage system. You only get what you pay for and it is worth every penny spent.”
