Harvia KIP45B: a 4.5 kW wall heater with built in controls for saunas from 100 to 210 cubic feet
The Harvia KIP45B is a compact stainless steel sauna heater made in Finland for small rooms, rated at 4.5 kW for saunas from 100 to 210 cubic feet, about the size of a one or two person closet sauna. It hangs on the wall, measures 16 inches wide, 11 inches deep, and 24 inches tall, and weighs 40 pounds empty. The stones sit in a mesh cage directly on the heating elements.
The box holds the heater and its manual. It runs on a 240 volt circuit, with nothing else to add except the stones. Two knobs built into the base set the temperature and a 60 minute timer, or delay the start by up to 8 hours so the room is hot when you get home. Sauna stones are sold separately, so add the 1 box it needs on the page. A bucket and ladle set is optional. Prefer a wall control outside the sauna? The Harvia KIP45W sauna heater pairs with a Xenio digital control. The Harvia KIP45B ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
Is this heater a good fit for a compact home sauna?
Yes – the 4.5kW KIP45B is rated for sauna rooms of 100 to 210 adjusted cubic feet, per its specification table, and its sleek 16 x 11 x 24 inch wall-mounted body is designed to be compact. Verify your room’s volume against that range and the installation manual on this page before ordering.
What can the built-in control panel do?
The control panel sits at the base of the heater and includes a 60-minute timer and a thermostat. It also lets you preset a startup delay of up to 8 hours, so you can have the sauna heating in advance – all without needing a separate wall-mounted control unit.
Do sauna stones come with it?
Stones are selected with your order rather than packed in the heater carton: the Required Stones option on this page covers the one-box, 50-lb minimum the heater requires. Because each natural stone is unique in shape and size, the page recommends an extra box for the best fit – additional freight charges apply.
What kind of circuit does it need?
The KIP45B operates on 240V single-phase power, with the specification table listing 18.8 amps. Leave the wiring to a licensed electrician working from the installation and operation manual and your local electrical codes – those, not the product page, determine the breaker and wire sizing for your sauna.
Why do the rocks sit right on the heating elements?
That is deliberate: this heater places the sauna rocks in direct contact with the heating elements, which the page notes produces a radiant, penetrating heat, while the large rock capacity maximizes efficiency and heat storage. The industrial-grade elements are also designed for ease of service down the road.
Where is it made, and what if I need more power?
The heater is designed and made in Finland and is UL listed, with a 2-year consumer-use warranty in the Includes tab and the full Harvia warranty PDF linked at the top of this page. If your sauna room is larger, Harvia’s KIP heater range comes in four power levels to suit your needs.
