Every real Finnish wooden tub or outdoor spa from SpaDealers can be equipped with a water heater: wood stove (15 or 25 kW), gas water heater (24 kW) or electric instantaneous water heater (1x3 kW or 2x3 kW), which are located only on the outside side of the portable spa. This allowed us to increase the usable space inside the heated hot tub and ensure rapid and even water heating throughout the volume with a water temperature difference of up to ~ 5-6 °! It is possible to choose from several types of hot water heating in a hot tub or use a combination of them. We want to draw our customers' attention to the difference between an external and an internal heater.
The electric water heater for the hot tub with the thermostat, as well as the hot water heater without the thermostat, has a power of 3 kW, which provides a water heating rate in the range of 1-2 ° C / hour.
