Why choose an electric hot tub?

Of course, we believe an electric hot tub can't quite replace the charm of wood-fired heating. What makes electric heating special, however, is its ease of use: with just the push of a button, you switch on the heater and it does all the work for you. What's more, your hot tub can be up to temperature within just 4-6 hours, depending on its capacity. And... no more smoke nuisance! That's another great advantage of an electric hot tub. In short: an electric hot tub is very simple to use, letting you enjoy warm water quickly and effortlessly.

Built-in hot tub heater

One variation of electric heating is a built-in heater from Pahlen. The great advantage of this option is that the heater is fully integrated into the hot tub, staying out of sight, so you keep a sleek and minimalist design. The built-in heater is available in three power outputs: 3, 6 and 9 kW, and is very easy to use. With just the push of a button, you switch on the heating. You easily adjust the temperature using the dial on the heater, up to a maximum of 45 degrees.

Heating with a heat pump

The new, modern way of heating with a heat pump is an energy-efficient and practical solution for your hot tub. The Inverboost heat pump is available in no fewer than 10 different power ratings, up to a maximum of 30 kW. 30 kW?! Yes, that's right. Thanks to the smart and innovative system, however, actual energy consumption is much lower: on average just 4.5 to 5 kW. The heat pump is easy to operate via the Inverboost app, giving you control over your hot tub's temperature anytime, anywhere. This makes the solution not only efficient, but also exceptionally user-friendly and practical. You can find more practical information about the heat pump here.

Electrical connection for electric hot tub

No heavy-duty power connection is needed for the 3 kW built-in electric heater. For the 6 and 9 kW versions, a heavy-duty power connection is required. Information about the power consumption and heat output of the heat pump can be found here.
