How much will a hot tub cost to run? That is one of the most frequently asked questions when someone is considering a hot tub. A number of factors influence the answer to that question such as ambient temperature, electricity supplier and tariff, how much you use your hot tub and more.
However ensuring your hot tub is as energy efficient as possible is the best way to help reduce running costs, so when choosing a hot tub you should consider:
Getting the water heated to a suitable temperature requires a heater, and the majority of hot tubs use an electric heater to do so, choosing a hot tub with a higher kW rating will heat your water faster but has no direct link to using more or less energy than one with a lower kW rating, for example a if a 1kW heater takes 3 hours to raise the temperature, then a 3kW heater would take an hour.
More importantly for improved efficiency choose a hot tub with a direct contact heater and ensure the heater utilises titanium heating elements.
Insulation inside the hot tub cabinet helps to lower running costs and increases energy efficiency. Most hot tubs feature foam-fill insulation which incorporates foam around the shell which helps to conserve the heat of the water resulting in increased energy efficiency and lower running costs.
Foam-fill insulation also secures and reinforces the plumbing to help avoid leaks and also helps to reduce the noise for a quieter hot tub experience.
Covering your hot tub when not in use helps to protect your hot tub, maintain the water temperature, ensures your water is clear of contamination and also adds an extra measure of security.
Choose a hot tub with an insulated cover as this will help reduce the loss of temperature in your water ensuring less energy is needed to keep your water hot.
