3 Things To Look For When Choosing An Environmentally Friendly Hot Tub

If you're shopping around for a new hot tub, size, comfort, reliability and above all good value for money are probably your most important concerns. However, in an age of ever-increasing temperatures and increasingly depressing headlines about climate change, many potential hot tub buyers are looking for hot tubs that are also friendly to the environment. 

Fortunately, finding a hot tub for sale with serious green credentials becomes easier every year, and hot tub buyers can choose from a range of models that minimize their energy, water, and chemical usage while maximizing comfort and fun. If you're looking for a hot tub with minimal environmental impact, keep the following guidelines in mind as you compare models.

Bigger is not better

The first step in choosing an eco-friendly hot tub is finding a hot tub that can comfortably accommodate everyone who wants to use it, without going too large and increasing your tub's water usage. For example, a family of five who want to relax after stressful day should choose a five- or six-seater hot tub model, while lone users who intend to use their hot tub regularly for its therapeutic benefits should opt for a single or dual-seater model (dual seat models tend to be more comfortable for taller users, especially if they want to stretch muscles in the lower body).

Consider salt water chlorination

Conventional chlorine tablets and powders are very efficient, but decidedly unfriendly to the environment — the highly toxic chlorine can poison plants and animals if spilled, and may leach into local groundwater supplies, causing widespread environmental damage. 

Choosing a hot tub with a built-in salt water chlorination system is a much more environmentally conscious choice. When loaded with ordinary table salt, these systems use a harmless electrical charge to chemically alter the salt as it enters the hot tub water, turning it into bacteria-killing chlorine. These unique chlorinators eliminate the risk of spillages and other chemical mishaps, and also require much less maintenance — many smaller hot tubs only need their chlorinators refilled once a year with moderate use.

Invest in insulation

Keeping the water in a hot tub warm requires a substantial amount of energy, and you can reduce the amount of energy your hot tub uses significantly by opting for a model that keeps water warm for as long as possible. A thick, well-fitted hot tub cover can be highly effective at keeping water warm, but obviously can't be used while people are using the hot tub.

To keep energy usage low even while the hot tub is in use, look for a model with thick foam insulation in the exterior walls and floor of the tub. This will reduce the rate at which heat escapes from your hot tub water, allowing you to run your heating element less often and save a considerable amount of energy. Floor insulation is particularly important if your hot tub will be placed on a concrete patio or deck, as the conductivity of concrete can cause water to cool down more quickly.
