Compatibility:
Rexener Bioheater should not be used with seawater as it can cause problems due to the high salinity and the warranty does not cover any damage that may occur.

Circulation:
Yes. The Rexener heater is so efficient that the heater does not operate optimally when in free circulation. If your pool (hot tub / pool) already has a circulation pump or sand filter system, you can take advantage of it with Rexener. If you do not already have a circulation pump or sand filter, you can easily order them from our online store while ordering a heater.

Installation and Maintenance:
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.
It is not necessary to move the heater indoors in winter, especially if it is in use. If the heater is drained of water, it can also be stored outdoors. Of course, it is always better to keep the device in a warm, sheltered place when not in use.
Water must not freeze inside the heater. If you wish, you can keep the water so warm that it does not freeze, so you do not need to drain the appliance. If the heater is not used (or the heat is not maintained), the unit must be emptied before frost.
The fuel remains in a weatherproof tank, so you don’t need to empty the tank even in frost. It is always advisable to change the fuel if the fuel stops for a long time.
In the frost, make sure that the heater uses winter grade fuel.
Behind the heater there is a drain plug for draining the water. So does the Rexener circulation pump.
