FAQ

HUUM Steel heaters work well in saunas from 175 to 500 cubic feet, depending on the power rating chosen. For best results, plan for 1kW of power for every 35-45 cubic feet of sauna space, considering insulation quality and desired heat-up time.

Most installations reach 150-170°F within 30-45 minutes from a cold start. The efficient design heats more quickly than many alternatives, with the exact time depending on room size, insulation quality, and starting temperature.

While mounting the heater is straightforward, the electrical connections require professional skills to ensure safety and proper function. We recommend certified electrician installation for warranty coverage and code compliance.

Check stones yearly and replace them every 1-2 years, depending on usage frequency. Cracked or crumbling stones should be removed right away to maintain proper function and prevent damage to heating elements.
