The Harvia KIP45W is a 4.5kW wall-mounted electric sauna heater for rooms from 100 to 210 cubic feet. The W in the model name identifies this as the external controller variant of the KIP45 platform - operation is managed through a separate Xenio CX170 controller (sold separately) rather than the built-in manual dials of the KIP45B. This distinction matters for buyers who want digital touchscreen control, Wi-Fi connectivity, and the ability to control the sauna remotely via the MyHarvia app. The polished stainless steel body uses dual-wall construction that keeps the exterior surface cool to the touch, allowing direct mounting on a wooden sauna wall with the included bracket. The large stone cavity holds 44 lbs of AC3000 stones (1 box, 5-10 cm, sold separately) with direct rock-to-element contact for efficient heat transfer and soft steam. Available in 240V/1PH for residential use and 208V/3PH for commercial installations. UL listed. ETL certified. Made in Finland by Harvia.
KIP45W - the external-controller variant of the most popular KIP configuration
The Harvia KIP is described by multiple authorised dealers as the most sought-after model in the industry - a traditional wall-mounted sauna heater that has been in continuous production and use for decades. The KIP45W is the W-model (external controller) variant of the 4.5kW KIP45 platform. The KIP series has two control configurations at each output level: the B-model (built-in controls) with manual temperature and timer dials integrated into the heater body, and the W-model (external controller) designed to be paired with a separate wall-mounted Xenio controller. The KIP45W is for buyers who want the KIP platform at 4.5kW with external digital control capability - touchscreen temperature management, precise scheduling, Wi-Fi connectivity, and remote app control from anywhere - rather than the simpler manual dial approach of the KIP45B.
KIP platform - dual-wall construction, large stone cavity, direct contact
The KIP45W uses the same proven KIP platform body as the KIP45B: dual-wall stainless steel construction that keeps the exterior cool to the touch, a large stone cavity for maximum heat release, direct rock-to-element contact for efficient heat transfer, and a protective stone guard. The dual-wall design means the heater body can be mounted at the specified 4.92" clearances on front and sides from combustible materials without any additional shielding - the outer steel surface stays cool enough for a wood sauna wall at the minimum distance. The wall mounting bracket is included. The compact 16.1"W x 11"D x 23.6"H profile leaves the full floor area usable for benches and movement within the room.
240V/1PH residential and 208V/3PH commercial - two configurations
The KIP45W is available in two electrical configurations: 240V/1PH for residential home saunas and 208V/3PH for commercial installations in apartment buildings, hotels, and health clubs. The 240V/1PH version requires a minimum 18.8A fuse and 10AWG supply cable. The correct configuration must be selected at the time of purchase. Both require the Xenio CX170 controller, which connects to the heater via the supplied control cable and can be surface or flush mounted in the sauna room, shower room, dressing room, or elsewhere within the rated cable distance. A licensed electrician is required for all wiring and installation per local code.

ℹ️ KIP45W (external Xenio controller) vs KIP45B (built-in controls) - same heater body, different control approach. KIP45B JH45BU1UL: 4.5kW, 100-210 cu ft, built-in manual dial controls - no controller required, simpler installation, lower total cost. Temperature dial on the left, on/off and 8-hour delay timer on the right. Choose if straightforward manual operation is preferred and digital remote control is not needed. KIP45W JH45WU1UL (this listing): 4.5kW, 100-210 cu ft, requires separate Xenio CX170 controller - digital touchscreen control, Wi-Fi connectivity, MyHarvia app access, precise temperature scheduling. Choose if remote control from outside the sauna room, smartphone app access, or digital scheduling capability are priorities. Both share the identical KIP heater body, stainless steel construction, dual-wall design, 44-lb stone capacity, 4.92" safety clearances, and UL listing. The difference is entirely in control method.

Why the Harvia KIP45W stands out
Xenio CX170 - digital control, Wi-Fi, and MyHarvia app
The KIP45W is designed to be operated with the Xenio CX170 - a touchscreen control panel with Wi-Fi connectivity and full MyHarvia app integration. Temperature, session duration, and scheduling can be set precisely from the Xenio panel in the sauna room or remotely from a smartphone before arriving. The MyHarvia app is available for both iOS and Android and provides complete heater control from anywhere within the Wi-Fi network. For a home sauna where remote preheat scheduling, precise temperature control, or app-based operation are priorities, the KIP45W with the Xenio CX170 provides all of these from the proven KIP heater platform. The controller is sold separately and can be surface or flush mounted at a convenient location.
Wall-mounted - full floor space preserved
The KIP45W mounts on the sauna wall using the included bracket, leaving the full floor area usable for benches, foot space, and movement within the room. For sauna rooms from 100 to 210 cu ft where every square foot matters, wall mounting is a meaningful layout advantage. The compact 16.1"W x 11"D x 23.6"H profile keeps the heater's footprint small on the wall. The bracket is designed for direct mounting on a wooden sauna wall at the 4.92" side clearances with no additional shielding required - the dual-wall construction manages the surface temperature at those clearances.
Dual-wall construction - cool exterior, safe at wood clearances
The KIP45W's dual-wall body keeps the exterior surface cool to the touch throughout the session. The outer stainless steel shell is separated from the inner heat-conducting components so that thermal energy is directed into the stone cavity and delivered as heat and steam, not radiated through the heater body. At 4.92" from combustible materials on front and sides, the cool exterior means no scorching, no discolouration, and no requirement for a non-combustible stand-off or shield between the heater body and wood walls. This makes installation straightforward on standard wooden sauna wall construction.
Large stone cavity with direct rock-to-element contact
The KIP45W's stone cavity holds 44 lbs of AC3000 stones (1 box, 5-10 cm) in direct contact with the industrial-grade heating elements. Heat flows from element surface to stone mass directly - stones are charged efficiently and produce soft, even steam when water is poured. The protective stone guard surrounds the stone bed and keeps the load in position during use. For a 4.5kW heater in a room from 100 to 210 cu ft, the 44-lb stone load is proportionally generous - enough thermal mass to produce consistent steam through a full session without rapid cooling between ladles.
The KIP - a traditional favourite for decades
The Harvia KIP is recognised across the industry as the most consistently purchased and longest-running electric sauna heater design in the market. Customers regularly replace 10-plus year old KIP units with new KIP units - the platform has earned a reputation for reliability, durability, and performance that makes it the default choice for straightforward home sauna installations. The KIP45W brings this proven platform to buyers who want external digital control. The stainless steel body, wall-mount bracket, protective stone guard, and direct-contact stone design are all unchanged from the KIP that has been in homes and saunas for decades. The Xenio CX170 adds modern control to a classic heater.
KIP Series platform - 4.5kW to 10.5kW, W and B models
The KIP45W is the 4.5kW external-controller entry point of the KIP Series W-model lineup. The KIP Series covers the range from small to large home saunas at four output levels: KIP45W (4.5kW, 100-210 cu ft), KIP60W (6.0kW), KIP80W (8.0kW, 247-424 cu ft), and KIP100W (10.5kW). Each W-model variant requires the Xenio CX170 controller. Corresponding B-model variants (KIP45B, KIP60B, KIP80B) have built-in manual controls and require no separate controller. All KIP models share the same stainless steel dual-wall construction, wall-mount bracket, protective stone guard, and direct rock-to-element contact. UL listed and ETL certified.
