Professional-Grade Sauna Heating for Smaller Cabins
The KOVE 4.5kW Sauna Heater is a compact, high-performance electric heater built to deliver a reliable traditional sauna experience in smaller cabins. Designed for consistent daily use, it provides fast heat-up, even temperature distribution, and simple mechanical control — ideal for home saunas, garden builds, and professional wellness spaces where dependable heat matters.
Fast, Even Heat Output (3–6 m³)
Optimised for sauna rooms of 3–6 m³, the KOVE 4.5kW heater warms the cabin quickly and maintains a steady sauna climate throughout the session.
A 15kg stone capacity (stones sold separately) helps the heater hold and radiate heat effectively, delivering a more stable, comfortable sauna environment — particularly once the cabin is fully up to temperature.
Built for High Heat & Humidity
Sauna environments are demanding, with constant heat cycling, moisture, and steam. The KOVE 4.5kW heater is designed for long-term durability using materials chosen specifically for these conditions:
-
Corrosion-resistant aluminised zinc outer casing for dependable performance in humid environments
-
304 stainless steel heating elements for reliable heat output and extended service life
- A compact, space-efficient form factor suited to smaller sauna cabins
Simple Mechanical Controls
Control is intentionally straightforward. The built-in mechanical dials allow you to set temperature and session duration quickly — ideal for shared spaces, rentals, or anyone who wants a simple, no-learning-curve sauna experience.
-
Temperature control: Adjustable up to 110°C
-
Timer: Up to 3 hours for flexible heat-up and session lengths
Wall-Mounted, Space-Saving Installation
The heater is supplied with a wall-mounting bracket for secure installation and clean positioning inside the cabin. For safe operation and effective airflow, it should be installed approximately 9cm above the floor, helping distribute heat evenly while keeping the footprint minimal.
Electrical requirements: Fixed-wired connection required. Installation must be carried out by a qualified electrician in accordance with UK regulations (Part P / BS 7671).
Sauna Stones (Required)
The KOVE 4.5kW heater is designed to operate with sauna stones, which stabilise heat output and improve overall sauna performance.
-
Stone capacity: Up to 15kg
-
Sauna stones: Sold separately
Correct stone loading helps protect the heating elements and improves heat consistency and steam quality.
