Harvia Club K10G: a 10 kW stainless floor heater for saunas from 388 to 600 cubic feet
The Harvia Club K10G is a floor-standing electric sauna heater made in Finland for home saunas and light commercial rooms, rated at 10 kW for spaces from 388 to 600 cubic feet. The body is stainless steel inside and out, with a curved front and a wire basket on top that holds 132 pounds of stones directly on the heating elements, so the heat comes off rock rather than bare metal. It is about 20 inches wide, 17 inches deep, and 27.6 inches tall, and weighs 60 pounds empty. Its layered walls keep the outer surface cooler to the touch.
The box holds the heater and its manual. It needs a Harvia Xenio wall control to run, and you add that on the page. Sauna stones are sold separately, so add the 3 boxes it needs on the page. On the page, choose 240 volt single phase for a home or 208 volt three phase for a commercial building. A bucket and ladle set is optional. Heating a larger room? The Harvia Club K12.5G sauna heater covers 494 to 742 cubic feet. The Harvia Club K10G ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
What size sauna room does a 10kW heater cover?
The spec table rates the Club K10G for sauna rooms from 388 to 600 adjusted cubic feet. It is engineered for both residential and commercial settings — homes, health clubs, hotels, and spas — so verify your room’s adjusted volume against the Harvia Club installation manual linked on this page before ordering.
Do I need to buy a control unit for this heater?
Yes — the K10G requires a Harvia Xenio control unit, and the Xenio CX30 digital control with WiFi appears as a required selection under Sauna Heater Controls when you order on this page. The description notes the control delivers smooth operation and temperature precision for every session.
How many stones does it take, and are they included?
It requires a minimum of 132 lbs of sauna stones, supplied as three boxes selected with your order on this page under Required Stones. Because each natural stone is unique in shape and size, the page recommends adding an extra box so you can pick the best stones for fit, form, and function.
What are the electrical options?
The heater is offered in 240V single-phase, drawing a nominal 41.7 amps across two circuits, or 208V three-phase at 27.3 amps — you choose your configuration in the Voltage and Phase selector on this page. A licensed electrician should complete the hookup per the manual and your local codes.
Is this heater safe for a family sauna?
The Club K10G uses multi-layer construction for a cooler surface temperature and greater safety, and its rocks sit in direct contact with the electric elements to filter harsh heat. It is UL tested and listed as well as ETL certified, and the safety guidance in the installation manual should always be followed.
How big is the heater itself?
It is a floor model measuring 19-7/8 inches wide, 16.9 inches deep, and 27.6 inches tall, weighing 60 lbs before stones, with a deluxe stainless steel interior and exterior made in Finland and a 2-year consumer-use warranty. It belongs to the Club series sauna heaters, which offer multiple power ratings to match your sauna size.
