SAUNA HEATER FAQS
The heater you need for your sauna depends on its size, type, and your preferences. First, calculate the sauna's cubic footage (length x width x height) to determine the heater's power requirements—smaller saunas (up to 100 cubic feet) typically need 3-4.5 kW heaters, while larger ones (300+ cubic feet) may require 9-12 kW. Choose between traditional electric or wood-burning heaters for a classic sauna experience, or opt for infrared panels for energy efficiency and direct body heating. Consider features like built-in controls, safety mechanisms, and design aesthetics. For a modern, high-performance option, brands like HUUM offer stylish and efficient heaters tailored to various sauna sizes and needs.
02. What Is The Lifespan Of A Sauna Heater?
The lifespan of a sauna heater typically ranges from 10 to 20 years, depending on factors like the quality of the heater, how often it is used, and how well it is maintained. High-quality heaters from reputable brands, such as HUUM, are designed to withstand years of regular use, but proper care is essential to ensure their longevity. Cleaning the heater regularly, checking and replacing any worn-out parts, and using the heater within its recommended capacity can all help extend its lifespan. Additionally, heavy usage or neglecting routine maintenance can shorten a heater's life, so taking care of your sauna heater is key to making it last for many relaxing years.
03. How Is My Sauna Heater Shipped?
Your sauna heater will be shipped via LTL freight in large, crated boxes. A delivery appointment will be scheduled before arrival.
04. How Much Does Shipping Cost?

05. How Do I Clean My Sauna Heater?
Cleaning your sauna heater is simple and essential for maintaining its performance. Start by turning off the heater and allowing it to cool completely to ensure safety. Remove the sauna rocks and inspect them for cracks or deterioration; replace any damaged rocks. Use a soft brush or cloth to clean away dust and debris from the heater’s surface and interior, taking care not to damage any wiring or delicate components. If the heater has a removable grate or guard, clean it with warm, soapy water and dry it thoroughly before reassembling. Wipe down the rocks with a damp cloth to remove any dirt or buildup, and reposition them evenly when placing them back into the heater. Regular cleaning will keep your sauna heater running efficiently and prolong its lifespan.
