Some people give Severin Borenstein a hard time for having a hot tub.The main reason for such high energy usage is the heating, which generally runs even on days when the hot tub isn’t being used, to keep the water from overcooling.
Holiday parks are more open to alternative heating systems, including solar and biomass boilers and heat pumps.Mr Rowntree says that an air-source heat pump can cut energy costs by up to 75%, and can pay for itself within three years. Of course, there is the option of a wood-fired hot tub. Its environmental impact would partly depend on whether the wood was from a sustainable source, but burning wood is always going to produce carbon dioxide.For tourism operators, another important component is guest behaviour. At AliKats, a set of chalets in the French Alps, the hot tubs are very popular.
As for the mid-week water change, the company believes that this is easily avoided with proper usage, such as showering before entering the hot tub.
