There are many tips to help you reduce costs. The most promising are:
Place the spa in a protected area near walls without strong wind access to reduce heat loss.
Use the insulation cover and ground insulation cloth to keep the water warm as much as possible.
Buy a small spa. Less water to heat, fewer costs.
Use the spa outdoors in summer and indoors in winter. It is much more expensive to maintain a constant warm temperature in winter.
Clean the hot tub regularly. A hard water treatment system and filtration system prevent the creation of calcium on the walls that significantly prolong the spa’s life.
