This is a complete kit containing everything needed to combine our TopSpa XS and Polar range of outdoor spas with a 35 kW wood burning stove.
It's an advantage to rental companies for instance, to have an additional energy source for rapid heating if the spa is used a lot and the water is changed often. Those who have access to cheap firewood can see it as economic to heat with wood. At the same time, you have access to the convenience offered by the electrical heating and efficient filtration.
