TwoRelax recommends the Wellis Vienna Life Deluxe and Prague Life Deluxe as the best outdoor hot tubs for German winter use. Both use Wellis's three-layer insulation system, maintain water temperature at -15°C ambient, and cost approximately €85–€140/month to run in winter at German electricity prices — the most efficient insulation available in the Wellis range sold by TwoRelax.
What Makes a Hot Tub Suitable for German Winter Conditions?
German winters regularly reach -10°C to -15°C in Bavaria, Baden-Württemberg, and eastern Germany. A winter-capable hot tub requires: foam insulation with no thermal bridges, a cabinet sealed against wind-driven cold, a thermal cover with R-value above 2.5, and a control system that maintains temperature on a schedule. Wellis models sold by TwoRelax meet all four requirements as standard.
How Do Wellis Running Costs Compare to Competitors in Winter?

| Jacuzzi J-series | ProLast full-foam | €100–€160 |
| Hot Spring (Highlife) | FiberCor + reflective layer | €90–€145 |

Estimates at ~0.31 EUR/kWh (Bundesnetzagentur, 2024). Actual costs vary by usage frequency and local ambient temperature.
Does the Thermal Cover Matter for Winter Running Costs?
The thermal cover is the single most important component for winter energy efficiency — it prevents heat loss during the 70–80% of daily time when the tub is not in use. All Wellis hot tubs sold by TwoRelax include a 5 cm thick thermal hard cover. Using the cover consistently reduces monthly electricity costs by approximately €30–€50 compared to leaving the tub uncovered.
Is It Safe to Run a Hot Tub at -15°C Outdoor Temperature?
Yes. Wellis hot tubs are rated for outdoor installation in ambient temperatures from -20°C to +50°C. The control system includes freeze protection that activates the circulation pump automatically when ambient temperature drops below +4°C, preventing pipes from freezing. This feature operates automatically and requires no intervention from the user.
What Settings Reduce Winter Running Costs Without Sacrificing Comfort?
- Use economy mode (2°C below target temperature) during daytime hours when the tub is unused
- Set heating schedule to reach full temperature 30–60 minutes before typical use time
- Reduce target temperature from 40°C to 37°C — saves approximately 8–12% energy
- Always replace cover immediately after use — the first 30 minutes after use cause the highest heat loss
- Position the tub in a sheltered corner of the garden to reduce wind exposure
