HUUM CLIFF 11kW Electric Sauna Heater — Floor-Standing
Slim Vertical Floor-Standing Sauna Heater for Rooms 354–566 cu ft | 165 lb Stone Capacity | Made in Estonia
The HUUM CLIFF 11kW is a floor-standing electric sauna heater designed for residential sauna rooms from 354 to 566 cubic feet. Its slim, vertical profile is engineered for space-efficient installation with reduced safety clearance requirements — making it an excellent choice for saunas where a traditional wider heater won’t fit.
Manufactured in Estonia from stainless steel, the CLIFF features an internal air duct design for efficient heat distribution, removable ribs for optimized stone placement, and direct contact between heating elements and stones. A compatible HUUM UKU control system and sauna stones are required for operation and are sold separately.
Who This Is For
The HUUM CLIFF 11kW is the largest model in the CLIFF Series — ideal for homeowners and sauna builders who need a high-output floor-standing heater for a large sauna room. Its slim footprint makes it a strong choice for installations where space is at a premium but output cannot be compromised.
