Just wanted to show off my new Tarm. About 1600 gallons of unpressurized storage buried outside the basement wall (to the left of the boiler), Hydrosmart HS115 lp boiler for backup. All plumbed in using the Tarm Biomass' stss1 plumbing schematic, with various small variations. Walk in basement, so its nice to bring wood in. To the left of the boiler is one of those huge lawn wagons with pneumatic wheels... Those are awesome for bringing in large loads of wood. Boiler install, homemade tankand all plumbing done by yours truly. Like my dad says, its handy to be handy.
