Kove x Harvia 4.5KW Electric Sauna Heater For 3–6m³ Saunas | KOVE-HARVIA45

Premium Scandinavian Sauna Heating

The Harvia Vega 4.5kW Sauna Heater is a refined, high-quality electric heater designed for smaller sauna cabins where reliability, even heat distribution, and clean Scandinavian design matter. Manufactured by Harvia in Finland — one of the most respected names in sauna heating — the Vega range is trusted worldwide in both residential and professional sauna environments.

Even Heat Distribution from Floor to Bench

Designed for sauna rooms of 3–6 m³, the Harvia Vega 4.5kW delivers fast, consistent heat with a structure that allows the heater to be mounted lower on the sauna wall.

This lower mounting position improves air circulation and ensures heat reaches the lower benches as well as the upper seating area, creating a more balanced and comfortable sauna environment throughout the cabin.

Full Stainless Steel Construction

The Vega features a full stainless steel outer casing, giving it a clean, modern appearance while offering excellent durability in high-temperature, high-humidity sauna conditions.

• Corrosion-resistant stainless steel housing
• Designed for long service life in demanding sauna environments
• Minimalist Scandinavian aesthetic

Built-In Controls for Simple Operation

The Harvia Vega is designed to be easy to use, with integrated control switches positioned ergonomically on the upper side of the heater.

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

This makes the Vega particularly well suited to shared spaces, rentals, and professional settings where straightforward operation is essential.

Flexible, Installer-Friendly Design

The heater’s symmetrical design means there is no left- or right-hand configuration to worry about — it can simply be mounted in position using the supplied wall-mounting rack.

Electrical connections are made from the side of the unit, improving accessibility during installation and reducing setup time.

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

Sauna Stones & Performance

The Harvia Vega 4.5kW heater uses sauna stones to regulate heat output and produce steam when water is added.

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

Correct stone loading helps protect the heating elements and improves heat stability and steam quality.
