The differences in electricity consumption between premium providers and cheap products are enormous. We know reports of electricity costs from 30 to 250 Euros and more per month! And so an alleged hot tub bargain quickly becomes a financial bottomless pit. And the ongoing operation quickly costs more than the entire hot tub ever cost at purchase. So be very careful what you buy. Unfortunately, the ongoing costs of a hot tub can exceed the purchase price many times over, and a hot tub costing e.g. 4000 Euros was not cheap if I then need 2000 Euros per year for operation. Therefore, hot tub electricity consumption is the most important point in ongoing costs.
What are these differences? What is important for low hot tub energy consumption?
- the perfect hot tub cover: with highly insulating foam, surrounding outer sealing lip, sealing strip between the two cover halves, suitable fasteners for tensioning, and generally the cover should be as thick as possible.
- the perfect overall insulation: Fully foam insulated models definitely consume less electricity than all comparable partially insulated models. Regardless of the fancy names these reduced insulations are given :-) So don't be fooled by names like Arctic Pack, Premium Insulation, Top Insulation, etc. In my opinion, full foam saves 50% of heat loss compared to partial foaming. However, there are only a few premium providers like Artesian Spas, Hotsprings, Sundance, etc. who dare to do this because the workmanship must be perfect. These manufacturers also guarantee electricity consumption of about 1 Euro per day. Leaks would be a problem with full foam, so the rule applies: Whoever fully foams builds pools that do not leak! That's why these hot tubs are also more expensive, but you quickly save about 6,000 Euros in electricity costs over 10 years!
- the perfect component choice for hot tub operation:
- small efficient circulation pump!!! Here there is everything from 80 watts to 500 watts. Sometimes also two-stage large pumps that circulate with low stage and 500 watts. That means at 20h circulation time there is about a difference of 8 kWh per day in power consumption
- efficient brand massage pumps
A few manufacturers guarantee low power consumption in writing. Notable here are Artesian Spas /Beta Wellness (Made in USA products from Artesian Spas - except Beta's own Infinity&Eco line), Hotsprings and Sundance/Armstark (Sundance Spas Made in Mexico - except the second cheap Chinese brand). Here about 1 Euro per day (at 21 cents/kWh) is guaranteed. Many other manufacturers talk about it. Many also falsely promise it, but in writing it is only available from very few like the three mentioned above. And the differences are striking. With a cheap Chinese product, you quickly have 3 Euros per day power consumption and that is then a 7000 Euro difference in power consumption over 10 years!
So that you can separate reputable providers from "less reputable" ones and also see exactly how much your hot tub really costs (including 10 years of operation), I have prepared a comparison table for download after this article. This table queries all relevant data and you can have it confirmed by the hot tub seller. This way you have an objective comparison of what costs will really come to you.
So be careful and have the power consumption confirmed in writing!!!
