WELCON explains outdoor sauna performance in freezing temperatures
WELCON EUROPE GmbH & Co. KG has provided technical insights into the operation of garden saunas during winter months. The company notes that suitable outdoor saunas can reach classic temperatures, such as 90 degrees Celsius, even when external temperatures drop below freezing.
Achieving high temperatures depends on several factors beyond just the heater's power, including the cabin's internal volume, wall construction, door quality, heat loss, and placement. While compact saunas with matched heating power can function effectively, lower outdoor temperatures increase heat demand, which may lead to longer heating phases and higher energy consumption.
Additionally, the company clarified that a 400-volt connection is not strictly necessary for all outdoor saunas. Compact models, such as the WELCON EASYHEAT series, can utilize a 230-volt sauna heater with 3.6 kW heating capacity to reach standard temperatures when paired with an appropriately designed cabin.
