Its elegantly curved design and smart connectivity options make it as beautiful as it is capable—a true statement piece that transforms your sauna into a modern wellness sanctuary.\u003c\/p\u003e\n\u003ch3\u003eThoughtful Finnish Design\u003c\/h3\u003e\n\u003cp\u003eThe Spirit series represents Harvia's vision of what a contemporary sauna heater should be. The curved black steel body flows naturally upward, designed to showcase the beauty of rounded sauna stones rather than hide them behind industrial housing. Every detail reflects Finnish design philosophy: functional, beautiful, and built to last.\u003c\/p\u003e\n\u003ch3\u003eSmart Safety Features\u003c\/h3\u003e\n\u003cp\u003eSafety is engineered into every aspect of the Spirit SP90E. Dual safety sensors monitor both the heater and sauna room temperature independently, preventing overheating from any source. An integrated weight sensor detects if items are placed on top of the heater, automatically preventing remote start-up—so you can preheat your sauna from anywhere with complete peace of mind.\u003c\/p\u003e\n\u003ch3\u003eWi-Fi Ready Convenience\u003c\/h3\u003e\n\u003cp\u003eConnect the Spirit SP90E to a Xenio Wi-Fi control package and manage your sauna from anywhere using the MyHarvia mobile app. Start preheating on your commute home, adjust temperature from your phone, or set schedules that match your routine. The heater is also compatible with standard Xenio wall-mounted controls for those who prefer traditional operation.\u003c\/p\u003e\n\u003ch3\u003eMaximum Power for Larger Spaces\u003c\/h3\u003e\n\u003cp\u003eWith 9 kilowatts of heating power, the SP90E handles sauna rooms from 177 to 494 cubic feet—the largest capacity in the Spirit lineup. This makes it ideal for spacious 3-5 person home saunas or light commercial use. The generous 110-pound stone capacity stores substantial thermal mass for consistent heat and satisfying steam when you pour water over the stones.\u003c\/p\u003e\n\u003ch3\u003eInstallation Requirements\u003c\/h3\u003e\n\u003cp\u003eThe Spirit SP90E requires a dedicated 240V circuit with 50-amp breaker and hardwired installation by a licensed electrician. A Xenio series control (sold separately) is required for operation. The heater includes a temperature sensor, wall-mounting bracket, and all necessary mounting hardware. Designed, engineered, and manufactured in Finland. ETL certified for safety. Backed by Harvia's 1-year residential and commercial warranty, plus Sauna Republic's dedicated customer support.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003ch3\u003eDesign \u0026amp;
