The Harvia KIP45B is a 4.5kW wall-mounted electric sauna heater for rooms from 100 to 211 cubic feet, built for small to medium home saunas with built-in manual controls - no separate controller required. The KIP45B is the built-in control variant of the KIP Series: two dials at the base of the heater handle everything. The left dial sets the temperature. The right dial is the on/off control and delay timer, letting the heater be set to start up to 8 hours in advance and automatically shutting off after 60 minutes of operation. The controls can be repositioned from the front face to the right side of the heater during installation for added layout flexibility. The polished stainless steel body with dual-wall construction holds 44 lbs of AC3000 stones (1 box, 5-10 cm, sold separately) with direct rock-to-element contact and a protective stone guard. 240V/1PH, 60Hz. UL listed. Made in Finland by Harvia.
Built-in controls - no separate controller needed, ready to wire and run
The defining feature of the KIP45B relative to the rest of the KIP Series is the built-in control panel. Where the KIP80W and other KIP E-model variants require a separate Xenio wall-mounted controller, the KIP45B has its controls integrated into the heater body itself - two manual dials at the base, accessible from the front or right side depending on how the controls are positioned during installation. For a home sauna where simplicity is the priority, there is no additional controller to purchase, wire, or mount on the wall. The heater is self-contained: set the temperature, set the timer, and the session runs and shuts off automatically. The 8-hour delay function allows the sauna to be preheated before arriving home without any digital setup or app.
KIP platform - dual-wall construction, large stone cavity, direct contact
The KIP45B shares the full KIP platform with the rest of the KIP Series. The dual-wall body keeps the exterior surface cool to the touch throughout operation, allowing direct mounting on a wooden sauna wall using the included bracket without scorching. The large stone cavity holds 44 lbs of AC3000 stones in direct contact with the industrial-grade heating elements - heat transfers from element to stone efficiently, and the steam produced when water is poured on the stones is soft and consistent. The protective stone guard keeps the stone load securely in position during use. At 16.1"W x 11"D x 23.6"H and 30 lbs net weight, the KIP45B is compact and practical for a small sauna room where wall space is at a premium.
2" safety clearances on all sides - flexible wall positioning
The KIP45B requires only 2" from combustible materials on the front, left, right, and floor (1PH). Ceiling clearance is 3.5 ft from the top of the heater. These are among the most compact safety clearances available for any sauna heater in this output class and allow the heater to be positioned against a sauna wall corner or sidewall with minimal loss of usable room area. The minimum room ceiling height requirement is 6.56 ft. All wiring must be performed by a licensed electrician per local code. The 240V/1PH configuration requires a minimum 18.8A fuse and 10AWG supply cable.

ℹ️ KIP45B (built-in controls) vs KIP80W (external Xenio controller) - choosing the right KIP configuration. KIP45B JH45BU1UL (this listing): 4.5kW, 100-211 cu ft, built-in manual dial controls - no separate controller required, simpler installation, lower total cost, ideal for small home saunas where straightforward operation is preferred. KIP80W JH80WU1IUL / JH80WU1MIUL: 8.0kW, 247-424 cu ft, requires Xenio CX170 controller sold separately - digital touchscreen control, Wi-Fi connectivity, MyHarvia app access, precise scheduling. Both share the same KIP platform: wall-mounted, dual-wall construction, stainless steel body, direct rock-to-element contact, protective stone guard, 2-year warranty. Choose the KIP45B for small rooms (100-211 cu ft) and straightforward built-in control. Choose the KIP80W for larger rooms (247-424 cu ft) and digital remote control capability.

Why the Harvia KIP45B stands out
Built-in controls - no separate controller to buy or install
The KIP45B's most practical feature is what it does not require. Where most Harvia electric heaters - including the KIP80W - need a separate Xenio wall controller purchased, wired, and mounted independently, the KIP45B has everything integrated into the heater body. Two manual dials at the base handle all control functions. One sets the temperature. The other turns the heater on immediately or programs a delayed start of up to 8 hours, then shuts the session off automatically after 60 minutes. For a straightforward home sauna installation where simple, reliable control is the goal, the KIP45B is complete out of the box - stones are the only required addition.
Controls repositionable - front or right side
The KIP45B's built-in control panel is not fixed to the front face of the heater. During installation, the two-dial control assembly can be repositioned to the right side of the heater body. This allows the controls to face the sauna room entry point, bench area, or any direction that makes practical sense for the specific room layout - rather than always facing forward regardless of where the bather is seated. The repositioning is done during initial installation with no tools beyond standard mounting hardware. It is a small but genuinely useful feature for optimising control access in a small sauna room.
8-hour delay timer - sauna ready on arrival
The right-side dial allows the KIP45B to be set to start up to 8 hours before it is needed. Set the delay in the morning before leaving and the sauna is fully preheated by the time the session begins - with no app, no Wi-Fi, and no digital panel required. The 60-minute auto shut-off means the heater turns itself off automatically at the end of the session even if the bather forgets, providing a safety backstop that makes leaving the heater running unsupervised during preheat straightforward. For a simple home sauna with predictable use patterns, the delay timer and auto shut-off cover the full range of operational needs without any complexity.
Dual-wall construction - mount directly on wood
The KIP45B uses the same dual-wall body design as the rest of the KIP Series. The outer stainless steel shell is separated from the inner components, keeping the exterior surface cool to the touch during full operation. This allows the heater to be mounted directly on a wooden sauna wall using the included bracket - the cool exterior prevents scorching at the 2" front and side clearances from combustible materials. For a small sauna room where the heater is close to wood walls, benches, and trim, the dual-wall construction eliminates the need for a non-combustible shield or standoff behind the heater body.
44 lbs of stones with direct rock-to-element contact
The KIP45B holds 44 lbs of AC3000 stones (1 box, 5-10 cm) in direct contact with the industrial-grade heating elements. Heat transfers from element surface to stone mass directly - the stones accumulate thermal energy efficiently and release it as soft, consistent steam when water is poured. The protective stone guard surrounding the stone bed keeps the load in position during use. For a 4.5kW heater in a room from 100 to 211 cu ft, the 44-lb stone load is proportionally generous - enough stone mass to produce quality steam across a full session without the stones cooling rapidly between ladles.
KIP Series platform - 4.5kW to 10.5kW, built-in or external control
The KIP45B is the entry configuration of the KIP Series in the built-in control (B-model) variant. The KIP Series covers the full range from small home saunas to medium commercial applications across four output levels: KIP45B (4.5kW, 100-211 cu ft), KIP60B (6.0kW), KIP80B (8.0kW), and corresponding E-model variants (KIP60W, KIP80W, KIP100W) that require a separate Xenio controller for digital and Wi-Fi control. All share the same wall-mounted platform, stainless steel dual-wall construction, direct rock-to-element contact, and protective stone guard. Choose the B-model for built-in simplicity. Choose the E-model for external digital control and Wi-Fi capability. We are an authorized Harvia dealer.
