Electric Sauna Heater Guide – Wattage, Cost & Installation

Looking to add an electric sauna heater to create a relaxing home spa sanctuary? This guide covers how to choose the right electric sauna stove by wattage needs, sizing considerations, average costs, necessary parts and proper DIY installation steps when adding heaters.

Overview of Electric Sauna Heaters

Sauna heaters create the dry warmth and stone-diffused heat allowing wooden enclosed rooms to reach 150-200°F temperatures. Electric sauna stoves provide convenient plug-in operation without needing venting like wood-burning heaters require.

Most electric heater models include the following components:

  • Temperature adjustable control panel
  • Heating elements generating ample wattage
  • Integrated wire guard protecting internal parts
  • Stone platform housing optional accessory rocks
  • Exterior housing complete with safety railings

Electric sauna heaters with digital controls give the most accurate means for setting and maintaining perfect sauna session warmth. Integrated timers allow automatic shut offs as well for safety.

Key Sizing Considerations for Electric Stoves

Picking the properly sized electric sauna heater ensures your space warms effectively. Check these factors when selecting a model rated by the kilowatts (or watts) produced:

  • Cubic square footage – consider not just floor space but also height of ceilings when calculating
  • Insulation amounts – better insulated spaces need fewer watts to retain ample ambient heat
  • Intended usage frequency – occasionally used household saunas may need more power each session than commercial spaces warming constantly
  • Number of users – Heat needs increase per person enjoying simultaneous sessions
  • Desired warmth degree – Some enjoy extreme temperatures up to 200°F requiring major wattage capability

Ideally pick a unit sized beyond your average needs to provide the occasional extra heating boost. Undersized units run excessively with higher burnout potential.

Sauna Room Size & Recommended Electric Heater Wattages

To narrow down heater wattage amounts needed, match your finished or in-progress sauna’s cubic footage to this general sizing chart:

  • 100-150 cubic feet = 4,500+ watts
  • 150-250 cubic feet = 6,000-6,500+ watts
  • 250+ cubic feet = 2 x 3,000-watt heaters or a single 9,000+ watt commercial heater

Small 1-2 person household saunas usually need a single robust 6,000 watt unit for example. Larger luxury home installations or commercial multi-person spas may require dual heater coordination achieving 12,000+ watts.

Average Electric Sauna Heater Costs

With wattage outputs ranging from 3,000-18,000+ watts, electric sauna stove prices understandably cover quite a wide range depending on capabilities. Roughly estimate costs starting in this general baseline range:

  • Basic 120V plug-in heaters = $600-$850
  • Dedicated 240V heater models = $900-$1,200
  • Commercial-grade units = $1,500+

More affordable household electric heaters work wonderfully for home use cases. Splurge on commercial grades offering stainless steel exteriors and higher output for luxury needs instead.

Necessary Additional Parts and Accessories

Beyond the heating unit itself, complete electric systems need certain supplementary gear:

  • Separate control panel – Allows adjusting temperatures from inside the sauna safely without reaching the hot heater itself
  • Extra heating rocks – Fill unused rock tray capacity boosting efficient warmth diffusion into air
  • Protective floor mat – Shields flooring underneath from heat damage with an insulating barrier
  • Ventilation additions – Cooling vents or ceiling fans prevent overheating issues

Optional accessories like chromotherapy lights also enhance relaxation when adding finishing touches down the road.

DIY Electric Sauna Heater Installation Fundamentals

When ready to safely add your new electric stove, follow this basic process:

Chooseideal placement

The unit should occupy about a third of total wall space positioned towards the midway back of benches without obstructing seating zones.

Level the base

Use shims securing the feet snugly to prevent future rattling or movement throwing internal sensors off.

Allow ample air circulation space

Maintain clearance distances on all sides indicated inside user manuals for adequate airflow. Confined space risks overheating damage.

Set protective barriers underneath

Heavy-duty thermal heat shields protect against infra-red rays penetration downwards potentially igniting floors below.

Connect power appropriately

Either plug into a dedicated outlet safely handling at least 15 amps or hire an electrician tackling hardwired 240V connections.

Test thriftily

Confirm all sensor readouts match set temperatures without overshooting targets once powered on initially. Start testing at gradual 100°F before working upwards to desired bench marks.

Finish filling in stones

Pour water over additional rocks filling submergible pits before fastening lids avoiding messy splashes when generating steam levels.

Adding Safety Accessories to Electric Heaters

Protect further against risks like burns, fires or overheating by:

  • Installing sturdy handrails if lacking for balance entering or exiting
  • Mounting magnetic switch locks allowing remote disabling
  • Using timer devices preventing accidental 24-hour operation
  • Adding emergency shut off buttons inside for quick power downs
  • Incorporating warning lights indicating active heating modes outside closed doors

Manufacturers offer all these add-ons compatible with most new electric heaters or controllers. The upgrades provide inexpensive extra security giving you total peace of mind.

FAQs About Electric Sauna Heaters

Are plug-in electric heaters safe?

Yes, modern 120V models utilize GFCI outlets and come UL certified meeting stringent safety protocols during manufacturing. Just don’t overload outlets with too high wattage needs demanding 240V capability instead.

What is the best temperature for an electric sauna heater?

Most popular electric heaters safely reach between 150-185°F ambient air temperatures considered ideal dry method ranges. Start around 100°F for new users working upwards in 10° increments towards preferences without overdoing length until acclimated.

How long should an electric sauna heater last?

Quality electric heaters operate reliably for 5-10 years when properly maintained according to use case scenarios. Commercial or residential units subject to constant use or extreme temperature settings experience shorter functional lifespans.

Should you leave the rocks in an electric sauna heater?

Yes, always leave rocks covering the heating elements inside electric stoves no matter the usage frequency. The stones prevent direct contact accelerating corrosion of expensive heating rods yet still effectively transmit infrared waves diffusing through air.


Installing new electric sauna heaters makes enjoying home spa sanctuary benefits amazingly easy thanks to convenient plug-and-play designs and precision digital controls. Just be sure to size the unit’s wattage output appropriately according to the cubic footage needing warmth.

Carefully test initially at gradual temperatures while observing all safety protocols regarding adequate ventilation and shielding. Soon you’ll achieve perfect customizable dry sessions improving health each time you de-stress inside.

Maintaining Electric Sauna Heater Performance

Get the most out of investments into quality electric heaters by following best practice maintenance guidance.

Clean heating rocks

Remove stone debris buildup hampering airflow or clogging drainage areas by rinsing monthly. Skip chemical cleaners eroding essential protective glazes.

Inspect wiring insulation

Check behind access panels ensuring exposure risks don’t accelerate cord fraying from consistent high heat operating conditions annually.

Confirm door seals

Make adjustments as gaskets loosen over years sometimes allowing uncomfortable escape of interior air preventing chamber containment.
