FAQs - Heaters For Sauna Spaces

What should I consider when choosing commercial sauna heaters UK?

It's important to consider the available power supply and amount of uninsulated areas, such as glass in the sauna, when choosing the right heater.. As well as considering the usage demands, space siz,e and desired experience

For high-traffic environments like spas, gyms, or wellness centres, electric heaters are typically preferred due to their efficient heating, programmable controls, and easy maintenance. All of our brands, such as Helo, Narvi, IKI, Tulikivi and HUUM offer commercial-grade models built for long-term durability and consistent performance.

For a more authentic atmosphere in outdoor or rustic settings, wood-fired heaters provide powerful, radiant heat and a traditional sauna feel. The HUUM hive wood burning sauna and Tulikivi hile brushed wood burning sauna are perfect options for this.

What should I consider when choosing domestic sauna heaters UK?

As Finnmark offers both wood-fired and electric heaters for domestic use, you have the choice to decide which one suits you and your sauna best. All of our supplies provide both electric and wood-burning stoves.

Electric heaters are the most popular choice for home saunas due to their convenience and precise temperature control. They’re ideal for indoor or outdoor setups where simplicity, speed, and low maintenance are key. For example, the Narvi NM Domestic Electric Heater, HUUM Drop Electric Sauna, and Helo Hanko STJ Electric Heater are all solid options.

Wood-fired heaters are perfect for those who want a more traditional, authentic retreat. They’re best suited to outdoor sauna rooms or remote locations where electricity may not be available – or where you want the natural crackle of fire and softer, radiant heat. Wood-burning stoves from brands like IKI or Narvi provide a ritualistic feel and immersive connection to nature.

Who are the leading brands offering sauna stones as well as heaters for saunas?

Sauna stones are the most essential sauna accessory, as they produce the characteristics “loyly” - the gentle yet invigorating steam that rises when water meets the heated stones. These stones are key to an authentic sauna escape, helping to produce the calm, moist heat that soothes the body and relaxes the mind.

We stock leading brands like HUUM, Narvi, and Helo that all offer a selection of sauna stones designed to enhance both performance and atmosphere. Our collections include high-quality olivine diabase and vulcanite stones, chosen for their excellent heat retention and ability to create soft, enveloping steam when water is poured over them. One example is the premium vulcanite sauna stones, which act as a striking visual feature in your sauna space and aid improved heat flow.

What are the key health benefits of healing with heat through saunas?

Healing with heat comes with lots of benefits for your body, both physically and mentally. Regular sauna sessions can help your muscles unwind, ease joint tension, and give your whole body a chance to fully relax. As your body begins to sweat, this increases blood flow, which supports cardiovascular health and gives your immune system a helpful lift.

Over time, many sauna users report improved sleep quality, reduced stress levels, and a greater sense of emotional balance and calm. Whether you choose an electric or wood-fired sauna heater, both create the consistent, therapeutic heat needed to unlock these wellness benefits. From soothing sore muscles to supporting mental clarity.
