KOVE x Harvia Vega 8kW Sauna Heater – High-Power Stainless Steel Heater for Large Saunas
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.

What owners say.
Questions about this cabin.
Does the cabin fit through a standard doorway?
Yes. Our cabins ship in flat panels, each under 142 × 110 cm, and assemble inside the room. Our installer Tom completes the build in three to four hours.
What electrical supply does it need?
A dedicated 16-amp spur on a 230V supply for two-person cabins. Single-person cabins run from a regular 13A socket. We arrange a free pre-install electrical survey for every order.
Is the wood treated? Will it off-gas?
No treatment, no glue, no off-gassing. Built from FSC-certified Western red cedar, mortise-and-tenon joined, and finished only with food-grade tung oil where the bench meets skin.
How long does it take to warm up?
Twelve minutes from cold to 60°C in hybrid mode. Eight minutes in pure infrared mode.
What's included in the price?
The cabin itself, full installation by a Telos maker, a starter care kit, and the lifetime warranty. Delivery, install, and the 60-night home trial are included for every UK and Ireland postcode.
