HUUM Electric Heaters – Efficient Heat, Maximum Control

If you want the convenience of consistent, reliable heating without sacrificing the feel of a traditional sauna, a HUUM electric heater is likely the right choice. Designed and made in Estonia, HUUM’s electric range delivers soft, consistent steam, clean Nordic aesthetics, and a surprising level of control — suitable for both compact home saunas or a full commercial suite.

Here’s what sets HUUM electric heaters apart:

  • Stone-Heavy Build for Gentle, Long-Lasting Steam: With an exceptionally large stone capacity, HUUM heaters deliver soft steam (leil) and even heat distribution that is close to to the feel of a wood-fired sauna.
  • Smart, Efficient Control: Use a control panel on the wall or upgrade to Wi-Fi and app-based systems that let you preheat your sauna remotely from your phone.
  • Award-Winning Nordic Design: With sculptural forms inspired by nature, like the DROP and CLIFF, HUUM brings minimalist designs into the sauna space – making them ideal for modern interiors.
  • Built from Premium Stainless Steel: Corrosion-resistant and built for longevity, HUUM electric heaters are engineered to handle the heat.
  • Energy-Efficient & Space-Smart: Whether you're looking for a heater for a small, urban installation or a larger wellness project, HUUM offers both compact and high-output models, all designed to run cleanly and efficiently.

Shaped by decades of sauna expertise, an electric HUUM sauna stove gives you the performance you'd expect, with a design you’ll want to show off.

HUUM Wood Stove – Traditional Heat, Refined Design

Whilst convenience is great, there's something irreplaceable about the ritual of a wood-fired sauna. A HUUM wood stove connects you to something timeless, slower, and deeply restorative. Crafted in Estonia, HUUM’s wood-burning stoves are rooted in a Nordic sauna culture where fire still defines the experience. These stoves honour that heritage – not by copying the past, but by refining it.

Here’s what makes HUUM wood stoves different:

  • Authentic Wood-Fired Experience: Lighting a fire by hand is part of the experience. HUUM wood stoves are made for those who see a sauna as a ritual. 
  • Optimised for Soft Steam: Like their electric counterparts, these HUUM stoves are built with generous stone capacity to ensure deep, even heat and the signature soft steam (leil) that defines a proper sauna session.
  • Modern Build, Traditional Soul: Each HUUM wood stove is engineered for clean, efficient combustion using durable stainless steel, while still embracing the essential textures of raw metal, flame, and stone.
  • Eco-Conscious Construction: HUUM is committed to sustainability, using recycled materials where possible and focusing on energy-efficient combustion across the wood-burning range.
  • Made for Remote & Off-Grid Use: With no need for electricity, HUUM wood-burning heaters are perfect for off-grid cabins, lakeside retreats, or anywhere you want total independence and deep quiet.

A HUUM wood stove is for those who value stillness, effort, and tradition. It’s heat with meaning – a slower kind of wellness that starts with fire and ends in silence.

Frequently Asked Questions

What makes HUUM sauna heaters unique in the market?

HUUM sauna heaters combine Estonian sauna tradition with modern design and smart functionality – a balance few brands achieve.

Founded by Siim Nellis, whose family has built sauna stoves for generations, HUUM draws on deep cultural knowledge to create heaters that prioritise soft steam, efficient performance, and timeless aesthetics. Whether electric or wood-burning, every HUUM sauna stove is crafted in Estonia using durable materials, minimalist forms, and a clear respect for the sauna as a ritual.

What maintenance is required for HUUM sauna stoves?

HUUM stoves are low-maintenance by design, but regular checks help ensure long-term performance.

A HUUM electric heater will only require occasional upkeep: inspect wiring annually, check the stainless steel casing, and replace sauna stones every 1-2 years to maintain soft steam and airflow. In commercial saunas, more frequent stone inspections may be necessary due to heavier usage.

Remember to check the heating elements periodically for signs of wear or damage to ensure optimal performance and safety.

A HUUM wood stove will need a bit more attention. Empty the ash pan regularly, inspect the chimney for soot build-up, and keep the firebox clean. Stone maintenance is the same, just replace them as needed to preserve heat efficiency and steam quality.

What's the difference in heat-up time between HUUM electric and wood stoves?

HUUM electric heaters typically heat up in approximately 40-45 minutes, but this can take more or less time depending on the size, insulation and location of the sauna. They’re ideal for regular use, especially when paired with a Wi-Fi control system that lets you preheat remotely.

HUUM wood stoves take a little longer (around 45-60 minutes) as the heat builds naturally through the fire. It’s less about speed, more about ritual. Many users see it as part of the experience. Heating time can vary depending on the location and outside temperature, especially if it's an outdoor sauna.

Both deliver the same result: soft, consistent steam thanks to HUUM’s high stone capacity. The choice depends on how you like to sauna. If you’re struggling to choose between the two, our Sauna Heater Buying Guide covers all the pros and cons for you.

Are HUUM sauna heaters suitable for DIY sauna builds?
