Kove x Harvia 8KW Electric Sauna Heater For 8–12 m³ Saunas | KOVE-HARVIA8

High-Output Scandinavian Heating for Larger Sauna Cabins

The Harvia Vega 8kW Sauna Heater is a powerful yet refined electric sauna heater designed for larger sauna cabins and frequent shared use. Manufactured in Finland, it combines clean Scandinavian design with Harvia’s proven reliability, making it a trusted choice for both residential and professional sauna installations.

Fast & Even Heat Distribution (8–12 m³)

Designed for sauna rooms with a volume of 8–12 m³, the Harvia Vega 8kW delivers strong, consistent heat while maintaining excellent temperature balance throughout the cabin.

The heater’s internal structure allows it to be mounted lower on the sauna wall, helping heat circulate effectively to both lower and upper benches. This creates a more comfortable, evenly heated sauna environment — particularly important in larger cabins and shared sessions.

Full Stainless Steel Construction

The Vega features a full stainless steel outer casing, offering a modern, understated appearance alongside excellent durability in high-temperature, high-humidity sauna environments.

• Corrosion-resistant stainless steel housing
• Designed for long-term performance in demanding sauna conditions
• Clean Scandinavian aesthetic suited to modern sauna interiors

Built-In Mechanical Controls

The Harvia Vega 8kW is designed for simplicity and ease of use, with integrated mechanical control switches positioned on the upper side of the heater.

• Mechanical temperature control up to 110°C
• Integrated timer for flexible session durations
• No external control panel required

This makes the Vega particularly well suited to family saunas, shared spaces, rental properties, and professional wellness environments.

Installer-Friendly & Flexible Design

Thanks to its symmetrical design, the heater does not require left- or right-hand configuration and can be mounted easily using the supplied wall-mounting rack.

Electrical connections are made from the side of the unit, simplifying installation and improving accessibility for electricians.

Electrical requirements: Fixed-wired connection required. Installation must be carried out by a qualified electrician in accordance with UK regulations.

Sauna Stones & Heat Stability

The Harvia Vega 8kW uses sauna stones to stabilise heat output and generate steam when water is added.

• Stone capacity: Approx. 20 kg
• Stones required: 1 box of 5–10 cm sauna stones (sold separately)

Correct stone loading helps protect the heating elements while improving heat consistency and steam quality during longer sauna sessions.
