What customers say
The Harvia Cilindro PC90 earns high praise primarily for its superior design and exceptional heat performance. Owners frequently describe the cylindrical stainless steel unit as an aesthetic centerpiece, elevating the sauna environment. Its large stone capacity is key, delivering consistently soft, voluminous steam and excellent heat retention that smaller heaters cannot match. Reliability is a noted strength, reinforcing the unit's premium quality. While the initial cost represents a significant investment, users seeking the gold standard for medium to large residential saunas find the resulting enveloping heat experience justifies the expense. Satisfaction remains deep among those prioritizing high performance and durability.
Know before you buy
You can customize your steam by where you pour water on the heater. Pouring water on the side of the unit produces a softer, gentler steam, while pouring water directly onto the top of the stone pile creates a much sharper, more intense burst of steam.
The PC90 is rated for sauna rooms between 141 and 494 cubic feet. If your sauna falls within this range, the 9kW output will provide efficient and consistent heating.
No, this model features built-in mechanical controls located on the base of the unit, allowing you to adjust the temperature and timer directly on the heater itself.
Yes, the unit is designed for versatility and can be installed against a flat wall or tucked into a corner to save floor space, provided you adhere to the manufacturer's required safety clearance distances.
This is a 9kW, 240V single-phase unit that requires a 37.5-amp circuit. We strongly recommend having a licensed electrician verify your home's electrical capacity and handle the installation to ensure it meets local building codes.
Because the Cilindro PC90 has a large 200-pound stone capacity, you should inspect the stones at least once a year. Over time, sauna stones can crumble or settle, so you may need to remove smaller pieces and replace them to ensure proper airflow and heating efficiency.
