Brian of Rhode Island was interested in an OWB-9 waste oil boiler. He has had an Omni OWH-250 forced air furnace for 10 years now and absolutely loves it. He’s expanding his shop and will be using this for additional supplementary heat. He services the OWH-250 himself and is extremely familair with our equipment. His shop size is 1,800 sq. ft. with 11 ft ceilings. After doing his research and talking to our sizing experts, he purchased a OWB25. Thanks for your business Brian!
