Finlandia / Harvia Part # ZSP-250 2500W Element for K12.5G-U3 heater is the factory-matched heating element that restores full output and efficiency to your 230v K12.5G-U3 sauna unit. Each heater relies on six of these 2500W elements working together to deliver fast, even heat across demanding residential or light-commercial installations. Designed specifically for Finlandia and Harvia construction, the ZSP-250 fits cleanly into the existing mounting and wiring locations, helping maintain proper electrical loading and safe operation. Its robust, high-temperature design is engineered to withstand repeated heating cycles, steam, and long operating hours without premature failure. Replacing tired or unevenly performing elements with genuine ZSP-250 components helps ensure consistent stone temperature, more stable room conditions, and a comfortable sauna experience session after session, while preserving the heater’s original performance characteristics.
