For cost savings, the hot tub is the most important quality and efficient insulation. Well we know that, and therefore we use for our whirlpools latest technology.
The basis is a quality hot tubs with cover that insulates hot tub above. Further release of heat insulation prevents the shells, and in particular casing and bottom.
Our hot tubs can be insulated polyurethane foam or modern Al-PUR films always sufficient powers to prevent heat loss and thus the money needed for heating hot tubs.
Not only used insulating material, but also a place that insulates are important.
Heat is needed to keep the inside of the hot tub and therefore isolate itself not only the shell but also the cladding and the bottom. It will create space that is heated by the heat pump to produce. No heat does not come to ruin.
