Optimize your sauna experience with the HUUM CLIFF Mini 3.5 kW, a high-performance electric heater designed specifically for limited spaces. This slim, sculptural heater combines modern Nordic aesthetics with precision engineering, allowing for remarkably small safety distances to walls. Perfect for compact residential home saunas, the CLIFF Mini ensures that even the smallest rooms can provide the authentic, soft steam (Loyly) of a premium Estonian spa.
Despite its compact profile, the CLIFF Mini features a high stone capacity and a unique internal structure that allows it to heat 25% faster than comparable heaters in its class.
Slim & Space-Efficient Design
The CLIFF Mini is engineered for tight installations where every inch counts. Its slim, wall-mounted profile allows for an industry-leading safety distance of just 2 inches from combustible walls. This makes it the ideal choice for small sauna cabins or custom-built home spas where traditional heaters would be too bulky or require excessive clearance.
Superior Heating & Steam
The HUUM CLIFF Mini is built with an integrated internal air duct that optimizes airflow, significantly reducing heat-up times and ensuring an even thermal climate. With a high stone capacity of 132 lbs (60 kg), the heater provides exceptional heat retention and steam production. When water is poured over the rounded stones, the CLIFF Mini generates the soft, consistent steam characteristic of traditional Finnish and Estonian saunas.
Durable Stainless Steel Craftsmanship
Each HUUM heater is precision-crafted in Estonia using high-grade stainless steel for maximum durability and corrosion resistance. The sculptural, vertically-oriented cage design is not just a visual statement; it is a functional choice that exposes the maximum surface area of the stones to the air for efficient heat radiation.
Easy Operation & Smart Integration
Designed for the modern home, the CLIFF Mini 4 (3.5 kW) operates on a standard 240V 1-phase connection (15 amp). It is designed to be paired with an external control system, such as the HUUM UKU series, which allows for precise temperature management and, with the Wi-Fi option, the ability to preheat your sauna directly from your smartphone.
