Have you ever wondered how energy efficient a Softub is, or how long it takes to warm the water up? Unlike most hot tubs, Softub has no dedicated heating element. Instead, it uses waste heat from the pump motor to warm the water, which is in a sense very clever design. On the other hand, since the pump (hydromate) consumes roughly 900 W, the warm-up process takes a bit longer. How long will it take? Use the calculator below to estimate warm-up time and energy for a Softub Portico (1100 L) based on outdoor temperature, starting water temperature, and…
