Would the heater be good inside an enclosed pool area?

Great question. On page 6 of the installation manual, it states to contact your local building or fire officials about restrictions and installation inspection in your area. They would be able to assist you with local building codes/restrictions in your area. If you have any further questions or need further assistance, please feel free to reach out to one of our experienced customer service representatives and they would be happy to assist you. Thank you and have a wonderful day.
