When considering purchasing a hot tub, there many details to consider. One of these being the energy consumption that will accompany your new home spa. That’s right, if you purchase a hot tub expect to see your energy bill climb. Purchasing the most energy-efficient model possible and making use of smart ownership practices, will minimize the financial toll that a hot tub has on your home. Make sure to consider these four points when looking into the energy-efficiency of a potential hot tub.
Fitted Cover and Quality Insulation
Both these points revolve around preventing the removal of heat from your hot tub. And the more your water temperature drops, the harder your hot tub has to work to heat the water. Properly fitting spa covers stop rising heat from escaping the spa. On the other hand, spas with full-foam insulation provide dense insulation, which serves to maximize heat retention.
Hot Tub Placement
A hot tub that’s sheltered on all sides or located by a house corner or tall trees, won’t lose heat as fast as one with all the sides exposed. Having barriers around your spa helps to shelter it from cold winds and retain some of the heat. So, determining the right place for your hot tub is just as important as which one you choose.
When it comes to energy-efficiency, basic is best. The more diverter valves and elbows and union points in the design, the poorer the jet performance will be and the more piping the water has to travel through. This allows for more heat to be lost as the water is cycled through the system.
Many hot tubs make use of lights on the exterior or inside the tub. Depending on the type of bulb being used, the amount of electricity that’s drawn upon varies. For instance, LED bulbs are much more conservative with their energy use than incandescent bulbs.
