HUUM DROP 4.5kW Electric Sauna Heater

Overview

The HUUM DROP 4.5 kW electric sauna heater combines a rounded wall-mounted profile with a traditional open stone basket. HUUM rates this US model for sauna rooms of approximately 106–248 cu. ft. (3–7 m³). Its compact footprint leaves floor area open while the stones provide the mass used for classic water-on-stone bathing.

Features

• 4.5 kW output: Sized for rooms within HUUM’s published 106–248 cu. ft. range.
• Wall-mounted installation: Keeps the heater off the floor and creates more usable room area.
• 55 kg (121 lb) stone capacity: A generous stone basket stores heat and supports traditional steam; stones are sold separately.
• Signature DROP shape: Rounded, water-drop-inspired design for a distinctive sauna focal point.
• Brushed stainless-steel finish: Dealer-listed finish suited to modern sauna interiors.
• Compatible with HUUM UKU: Requires a compatible control system, sold separately.
• US 240 V, 2-phase wiring: HUUM’s US manual specifies a 30 A breaker and minimum 10 AWG wire for this model.
• Room-volume guidance: Select the heater from measured room volume and account for any manufacturer-required adjustments for exposed masonry, tile or glass.
• Installation-specific clearances: Required spacing depends on the model and room geometry; use the complete manual diagram.
• Heater-only purchase: Control, stones and any separately listed accessories are not included unless specified in the order.

Specifications

What's Included

The HUUM DROP set includes the heater, wall-mounting plate, reflector, heating-element retaining/support parts and installation/operation instructions. Included small parts vary by heater model. HUUM lists a heat diverter in the DROP 9 set.

Required separately: A compatible HUUM UKU control system and approximately 55 kg of suitable sauna stones. Verify accessories and current package contents for the selected model before installation.

Installation

• Confirm room volume is within 106–248 cu. ft. and apply the manual’s volume adjustment for any uninsulated stone, tile or glass surfaces.
• A qualified electrician must verify the dedicated 240 V, 2~ supply, 30 A breaker, minimum 10 AWG cable, grounding and local-code requirements. BathingBrands lists “240V/1PH,” while HUUM’s US documentation specifies 240 V, 2~; the manufacturer manual and electrician’s determination should govern.
• Mount the heater to suitable wall framing using the supplied mounting plate and hardware.
• Install the compatible UKU control and sensor as directed.
• Maintain all model-specific clearances to walls, benches, ceiling and nearby materials; do not rely on a single clearance measurement.
• Arrange the stones as instructed so air can circulate and heating elements are protected. Do not operate the unit without stones.

Operation and Usage

Operate the DROP heater only with a compatible HUUM UKU control installed and stones loaded according to the manual. Preheat through the controller. For traditional steam, add clean water sparingly to the stones only; keep water away from controls and electrical parts.

• Keep towels, clothing, oils and other combustible materials away from the heater.
• Supervise children and keep users clear of hot surfaces and required safety zones.
• Switch off and arrange inspection if the heater, control, wiring or stones are damaged or malfunction.
• Sauna bathing involves heat exposure and dehydration risk. Avoid alcohol, hydrate appropriately and leave the room if you feel unwell. Consult a healthcare professional if a condition or medication may affect heat tolerance.
