We want you to feel good about choosing Sauna Marketplace long after your first session, and confident recommending us to a friend. That standard guides the advice we give, the products we sell, and the way we take care of our customers.

How It Fits

How This Product Fits the System

What it is used for

An electric sauna heater that heats the sauna room and stone mass for traditional löyly. Choose the output from adjusted room volume, then match the exact voltage, phase, circuit, controls, stones, clearances, and ventilation.

What to plan

  • Size from adjusted sauna volume, including the effect of glass, masonry, and other uninsulated surfaces; do not size from floor area alone.
  • Match the selected model's power or fuel, voltage, phase, circuit, wire, control, stone, and venting requirements before ordering.
  • Treat clearances, ceiling reference planes, ventilation, guarding, floor protection, and service access as one room-layout decision.
  • Follow the current installation manual and use a qualified installer.

    Choose a HUUM UKU controller (required)

    Your heater will not run without a UKU. Local mounts outside the hot room and runs the sauna from its own panel. Wi-Fi does the same and adds scheduling and remote start from the HUUM app, which is what you want when the sauna is not ten steps from the couch. Every finish below is the same controller underneath, so pick on looks and budget. Already own a UKU? Take the first option and we will check yours against this heater before anything ships.

    Why buy a HUUM Sauna Heater from Sauna Marketplace?

    Why choose HUUM CLIFF

    CLIFF is the HUUM stone tower for narrow rooms. Its open sides keep the stones in view, and the slender body and short clearances leave more space for benches and walking.
