Harvia KIP45W: a 4.5 kW wall heater for small saunas from 100 to 210 cubic feet
The Harvia KIP45W is a small, wall-mounted electric sauna heater made in Finland, rated at 4.5 kW for saunas from 100 to 210 cubic feet, or a one or two person room. Its rectangular stainless steel body has a light gray finish. It measures 16 inches wide, 11 inches deep, and 24 inches tall and weighs 40 pounds empty. The mesh cage on top holds an unusually large load of stones for its size, with the stones resting directly on the stainless steel heating elements.
You get the heater and its manual. It needs a Harvia Xenio wall control to run, and you add that on the page. There are no knobs on the heater itself. The digital wall control lets you keep the timer and thermostat outside the hot room. Sauna stones are sold separately, so add the 1 box 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. Rather have the controls on the heater? The Harvia KIP45B sauna heater has them built in. The Harvia KIP45W ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
Will this heater work for a small home sauna?
Yes – the 4.5kW KIP45W is sized for sauna rooms from 100 to 210 adjusted cubic feet, making it one of the smaller wall-mounted electric sauna heaters in the lineup. Check your room’s volume against that range and confirm final sizing with the installation and operation manual linked on this page.
Do I have to buy the control separately?
The KIP45W needs a wall-mounted time and temperature control to run, and one is not in the heater box – but you do not have to hunt for it elsewhere. The Harvia Xenio CX170 digital control with WiFi appears under the Required Sauna Heater Controls selector on this page, so it is added right along with your heater order.
How many sauna stones does it take?
A minimum of 50 lbs of stones – one box – is required, selected through the Required Stones option when you order on this page. Natural stones vary in shape and size, so the page recommends an extra box to give you more choice for fit, form, and function; additional freight charges apply to the extra box.
What are the electrical requirements?
The specification table lists 240V single-phase operation at 18.8 amps or 208V three-phase operation at 12.5 amps. Hookup should be completed by a licensed electrician following the installation and operation manual and your local electrical codes – those determine the correct breaker and wiring for your installation, not the product page.
How much electricity does it use per session?
This is a 4.5-kilowatt heater, so at full output it draws about 4.5 kWh for each hour it runs – an hour and a half of operation uses roughly 6 to 7 kWh. Actual consumption depends on your room size, insulation, and thermostat setting, so treat that as an upper-bound estimate.
What comes in the box, and what is the warranty?
The Includes tab lists the sauna heater itself, the installation and operation manual, and a 2-year warranty for consumer use. The required stones and wall-mounted control are chosen through the selectors on this page so everything arrives in one order, and the full Harvia warranty PDF is linked near the top of the page.
