Wood Burning vs Electric Sauna Heaters - Which is Right for You?

Choosing a sauna heater is one of the most important decisions in any sauna project. The heater defines the character of the heat, the atmosphere of the sauna and the overall bathing experience, so getting the choice right matters. At Home of Clay we stock a comprehensive range of Harvia sauna heaters covering both wood burning and electric options, and this guide will help you understand the key differences so you can choose the right heater for your sauna, your space and your lifestyle.

Wood Burning Sauna Heaters

Wood burning sauna heaters are at the heart of the authentic Finnish sauna tradition. For those who want the genuine article, the crackle of a real fire, the smell of burning wood, the slow build of heat through a large stone mass and the deeply atmospheric experience of tending a fire before a sauna session, a wood burning heater is the only choice.

Harvia's wood burning range includes some of the finest heaters available in the UK. The Harvia Legend range covers the Legend 150, Legend 150 SL, Legend 240 SL, Legend 240 GreenFlame and Legend 300, representing the pinnacle of wood burning sauna engineering with large stone capacities ranging from 120kg to 260kg, powerful outputs from 16kW to 23.5kW and a range of installation configurations including through-wall SL models for loading from an adjacent room. The Linear range covers the Harvia 16, Linear 16, Linear 18 Compact and Linear 22 GreenFlame LS, offering more compact wood burning options for smaller sauna rooms. The Pro 20 SL and Pro 20 Duo SL provide a unique 2-in-1 sauna heater and through-wall fireplace experience.

The Advantages of Wood Burning

The heat produced by a wood burning heater with a large stone mass is widely regarded as the finest sauna heat available. The stones absorb an enormous volume of thermal energy during the firing process and release it slowly and gently throughout the session, producing a soft, enveloping warmth that maintains a consistent temperature and responds beautifully when water is poured over the stones for steam.

Many sauna enthusiasts find that the ritual of building and tending the fire is as much a part of the sauna experience as the bathing itself. Wood burning heaters are also the right choice for outdoor saunas and locations without convenient access to mains electricity. Harvia's GreenFlame technology, featured in the Legend 240 GreenFlame and Linear 22 GreenFlame LS, reduces carbon monoxide emissions by approximately 70% compared to standard wood burning heaters, making it the most environmentally responsible wood burning sauna heating available today.

The Practical Considerations of Wood Burning

Wood burning heaters require more preparation time than electric alternatives, typically one to two hours from lighting the fire to reaching bathing temperature depending on the heater, the stone capacity and the sauna room size. They also require a chimney or flue installation, a supply of dry firewood and a degree of ongoing attention during the heating process. For those who want to walk in and start bathing immediately, an electric heater may be the more practical choice for everyday use.

Electric Sauna Heaters

Electric sauna heaters offer unmatched convenience. They heat up quickly, are straightforward to control, require no chimney installation and can be switched on remotely, making them the most practical choice for everyday home sauna use. For those who want a high quality sauna experience without the preparation time and practical demands of a wood burning heater, an electric option is often the better fit.

At Home of Clay we stock the Harvia Delta Combi D29S, a unique combined electric heater and steamer that offers traditional sauna, steam sauna, herbal sauna and fragrant sauna modes from a single compact corner-mounted unit, ideal for small sauna rooms of 1.5 to 4 cubic metres. For those who want a dedicated electric sauna heater for a larger room, our team can advise on the most suitable Harvia electric model for your specific sauna room size and requirements.

Steam Generators

For those who want a pure steam room experience rather than a traditional dry sauna, Harvia's HGD and HGP steam generator ranges provide professional-grade steam performance for home and commercial installations. The HGD range covers outputs from 4.5kW to 15kW suitable for rooms of 2 to 28 cubic metres, whilst the HGP220XW extends to 21.6kW for the most demanding professional spa applications. All models in the HGD and HGP ranges feature MyHarvia WiFi app control, the Harvia Xenio touch-screen panel and titanium heating elements for exceptional longevity.

Which is Right for You?

The honest answer depends on how you plan to use your sauna and what kind of experience you want from it.

Choose a wood burning heater if you want the most authentic Finnish sauna experience, you have an outdoor sauna or a location without easy mains electricity access, you enjoy the ritual and atmosphere of a real fire, or you want the largest possible stone mass for the softest and most consistent heat. The Harvia Legend range is the natural starting point for those who want the finest wood burning sauna experience.

Choose an electric heater if you want to be able to use your sauna at short notice without lengthy preparation, you have a smaller indoor sauna room, you want precise temperature control at the touch of a button, or everyday convenience is more important to you than pure authenticity. The Harvia Delta Combi is an excellent choice for compact indoor saunas and those who want the flexibility of multiple sauna modes.

Choose a steam generator if your priority is a steam room rather than a traditional dry sauna, or if you want to add a steam facility to an existing shower enclosure or tiled steam room. The Harvia HGD range provides an outstanding steam room experience for home and commercial installations of all sizes.
