KOVE 8kW Electric Sauna Heater – High-Power Wall-Mounted Heater for Large Saunas

Sale price  £189.00 Regular price  £229.00

Maximum Power for Large Sauna Cabins

The KOVE 8kW Sauna Heater is a high-output, professional-grade electric heater designed for larger sauna cabins and frequent shared use. Built for demanding environments, it delivers fast heat-up times, excellent temperature stability, and strong steam performance — making it ideal for spacious home saunas and commercial wellness settings.

Powerful Heating for 9–14 m³ Saunas

Engineered for sauna rooms between 9–14 m³, the KOVE 8kW heater provides the additional power required to heat larger spaces efficiently and maintain consistent temperatures throughout longer sessions.

A generous 25kg stone capacity (stones sold separately) allows the heater to store and radiate heat steadily, improving thermal stability and producing richer, more controlled steam when water is added to the stones.

Built for High-Demand Sauna Environments

The KOVE 8kW heater is constructed using materials selected specifically for durability, safety, and long-term performance in high-heat, high-humidity conditions:

  • Aluminised zinc outer casing for corrosion resistance and structural longevity
  • 304 stainless steel heating elements for rapid heat-up and even heat distribution
  • Robust internal components designed for frequent daily operation

This makes the heater well suited to both private installations and professional settings where reliability is critical.

Simple Mechanical Controls

Like all KOVE sauna heaters, the 8kW model uses clear, mechanical control dials — ideal for shared use and commercial environments where ease of operation matters.

  • Temperature control: Adjustable up to 110°C
  • Timer: Up to 3 hours of continuous operation

No complex electronics, no learning curve — just dependable, intuitive control.

Wall-Mounted, Space-Efficient Installation

The heater is supplied with a wall-mounting bracket for secure installation and optimal airflow. For safe operation and effective heat circulation, it should be installed approximately 9 cm above the floor.

Electrical requirements: Fixed-wired connection required. Installation must be completed by a qualified electrician in accordance with UK regulations (Part P / BS 7671).

Sauna Stones (Required)

The KOVE 8kW heater is designed to operate with sauna stones, which protect the heating elements, regulate heat output, and improve steam quality.

  • Stone capacity: Up to 25 kg
  • Sauna stones: Sold separately

Correct stone loading is essential for performance, safety, and long-term reliability.

Which Heater Size Is Right for You?

  • Choose 8kW if your sauna is large (9–14 m³) or used by multiple people at once
  • Ideal for barrel saunas, large garden saunas, and commercial cabins
  • For medium-sized saunas, a 6kW heater may be sufficient

Ideal For

  • Large home sauna cabins
  • Outdoor barrel and garden saunas
  • Gyms, hotels, spas, and wellness facilities
  • Shared sauna sessions and extended use

Warranty Overview

Consumer Customers (B2C – UK)

Unless a shorter product-specific warranty period is stated within this guide, KOVE products supplied to consumers include a 2-Year KOVE Manufacturer’s Warranty commencing on the date of delivery.

The standard consumer warranty is structured as follows:

  • Year 1: Parts and labour;
  • Year 2: Parts only.

Where a product or component has a shorter warranty period stated within this guide, that shorter product-specific warranty period applies.

During the applicable warranty period, KOVE will, at its discretion and where a valid manufacturing defect is confirmed:

  • Repair the product;
  • Repair or replace the defective component;
  • Supply replacement parts where appropriate;
  • Replace the product with a new, refurbished or equivalent model; or
  • Provide a refund where repair or replacement is not considered appropriate.

The method of resolution will depend upon the nature of the fault, the age of the product, product availability and the requirements of applicable consumer legislation.

This warranty is provided in addition to your statutory rights.

30-Day Commercial Returns Policy

KOVE also offers a voluntary 30-day returns policy for unused, unopened products returned in their original packaging.

Return shipping charges apply unless otherwise agreed by KOVE.

This policy is separate from any statutory cancellation rights available under applicable consumer legislation.

Customer Responsibilities

To maximise product performance and maintain warranty coverage, customers are responsible for:

  • Installing products in accordance with the supplied instructions and local laws.
  • Using products only for their intended purpose.
  • Following all maintenance procedures contained within the user manual.
  • Maintaining products in a clean and serviceable condition.
  • Reporting faults promptly once they become apparent.
  • Preventing avoidable damage through continued operation after a fault develops.

Failure to carry out reasonable maintenance may result in damage that is not covered under this manufacturer’s warranty.

  • Use only water treatment products approved or recommended by KOVE.

  • Protect the unit from freezing conditions.
  • Drain the unit before temperatures fall below freezing.
  • Follow all maintenance procedures contained within the user manual.

Commercial & Shared Use

KOVE chillers may be suitable for shared use, gyms, studios and frequent plunging routines, provided the correct model has been selected and appropriate maintenance is carried out.

Higher usage places greater demands on the filtration system. As a minimum, the secondary hair net filter should be inspected and cleaned daily, or more frequently where required. The larger filter cartridge should also be inspected regularly and replaced whenever water flow becomes restricted or in accordance with the maintenance schedule.

If you are purchasing a chiller for commercial or shared use, we strongly recommend contacting the KOVE team before ordering so we can discuss your setup and recommend the most suitable product.

Where a product is used in an environment or application for which it is not designed, or contrary to KOVE’s recommendation, warranty coverage may not apply where that use has contributed to the fault.

Warranty Exclusions

The warranty does not cover damage resulting from:

  • Dirty or blocked filters;
  • Restricted water flow;
  • Failure to replace filter cartridges;
  • Poor water chemistry;
  • Corrosion caused by unsuitable chemicals;
  • Freezing damage;
  • Inadequate ventilation;
  • Incorrect electrical installation;
  • Power surges or unstable electrical supplies not attributable to the product;

  • Installation must be completed in accordance with the supplied instructions and local laws.
  • Electrical work should be completed by a suitably qualified electrician where required.

  • Check benches and fixings.
  • Keep ventilation openings clear.

Timber

Timber is a natural material. As a result, it may naturally:

  • Expand and contract;
  • Develop minor checking or surface cracks;
  • Display knots;
  • Change colour over time;
  • Fade due to UV exposure;
  • Show minor movement resulting from seasonal humidity.

These characteristics are not manufacturing defects unless they materially affect the structural integrity or safe operation of the product.

Sauna Heater Elements

Sauna heater elements that reach the end of their normal service life through regular use are considered consumable components and are not covered under this warranty.

However, heater element failures resulting from a manufacturing defect remain covered during the applicable warranty period.

  • Excessive moisture beyond normal operation;

Oxygen Concentrator Service Life

The supplied oxygen concentrator is designed with an expected service life of approximately 1,600 operating hours before major servicing or replacement may be required.

This service life is dependent on operating conditions, maintenance and usage.

The oxygen concentrator remains covered against manufacturing defects during the applicable warranty period. However, normal performance degradation or replacement resulting from reaching its expected service life is not considered a manufacturing defect and is not covered under warranty.

Replacement oxygen concentrators and spare parts remain available from KOVE.
