Some individuals view owning a hot tub as a significant consumer of energy, primarily due to high heating requirements, even when the hot tub is not in use. Research conducted by Prof Severin Borenstein at the University of California, Berkeley, sheds light on the energy consumption patterns of hot tubs.
Prof Borenstein's analysis revealed that heating the hot tub daily accounted for about 18% of his household’s electricity usage, equating to greenhouse gas emissions comparable to a transatlantic flight.
To address the energy inefficiency of hot tubs, various strategies can be employed. One critical aspect is the power source for heating the tub, with green energy options recommended to reduce the carbon footprint. Additionally, utilizing solar water heating and energy-efficient heat pumps can significantly lower electricity consumption.
Karl Rowntree, a technical director in the hot tub industry, emphasizes the importance of insulation, tub size, and temperature settings in enhancing energy efficiency. Innovations like sleep timers and control system features can further contribute to reduced energy usage.
For tourism operators like AliKats in the French Alps, managing guest behavior plays a crucial role in minimizing hot tub energy and water consumption. Implementing policies such as extra charges for summer hot tub use and discouraging drinking in hot tubs can lead to substantial environmental benefits.
The hot tub market has experienced fluctuations in recent years, with a surge in sales during the pandemic-driven staycation trend. Despite the maintenance costs associated with hot tubs, many in the tourism industry view them as essential amenities that drive bookings and customer satisfaction.
Prof Borenstein highlights the holistic perspective on hot tubs beyond mere energy consumption, underscoring their potential health benefits like stress relief and improved sleep quality.
