High Efficiency (e-models)
    The outdoor furnace is sited 30-100 ft from the house, preferably down wind. Insulated pex lines are run underground from
the wood furnace to your basement or crawl space. Hot water from the outdoor furnace is piped first to the water heater. A
flatplate heat exchanger is used to preheat the water entering the water heater. The supply from the outdoor furnace then
continues on to the air handler or boiler. A coil is placed in the duct or another flat plate is used for a pressurized boiler. Your
existing water heater and heating system ( heat pump, gas furnace, boiler, etc.) will still work as they always did but are now
used only as a back up.
