Rexener Bioheater can be installed up to 10 meters from a swimming pool or a hot tub. So it doesn’t have to be right next to the pool. The circulation pump handles water recycling. It is good to place the heater in a place where it can be easily adjusted. It should be installed on a stable surface that is free of water. The heater feet are adjustable. The fuel tank requires a safe platform. Make sure the tank is located where it is easy to refuel.
