MUST READ BEFORE BUYING THE UPGRADED HEATER

Please note the following disclaimer regarding the use of UPGRADED HEATERS:

The standard heater provided with the sauna has undergone careful testing for general use, capable of reaching temperatures of 170-180°F suitable for mass usage. Upgraded heaters such as Huum and Saunum models are specifically designed to reach higher temperatures, ranging from 190°F to 220°F. It is at the sole discretion of the customer to opt for higher temperatures.

Customers are reminded that Upgraded Heater's temperature regulation is essential and must be continuously monitored using the heater's UKU control. Leaving the heater unattended at high temperatures can result in wood discoloration and damage to the digital controls inside the sauna. In such cases, any resulting issues will not be covered under warranty, and CalmSpas assumes no liability for any damages incurred.
