Is an Efficient Electric Sauna Heater Worth It? Savings and Payback (2026)
With electricity at 18.3¢ per kWh in the US, the saving is too small to justify the purchase: 8.0 years to pay back if you replace a working electric sauna heater, and 8.0 years for the extra cost of the efficient model when you are replacing anyway.
An efficient electric sauna heater cuts electricity by 77%: about 1,697 kWh, worth $311.23 a year in the US. Not for the electricity
- From
- Traditional electric sauna stove, 6 kW, about 2,190 kWh a year
- To
- Infrared cabin, 1.8 kW, short warm-up, about 493 kWh a year
- Usage
- One session a day
| Scenario | You pay | Payback | Net over its life |
|---|---|---|---|
| Replace a working electric sauna heater now | $2,500 | 8.0 years | $2,168 |
| Replacing anyway: choose the efficient one | $2,500 | 8.0 years | $2,168 |
Prices are typical figures; type your own quotes above. Net over its life is the total saving over the years it lasts minus what you pay. It ignores inflation, interest and changes in electricity prices, which is conservative while prices are rising.
Our take
Only worth it if you would be happy with infrared heat, which is a different experience. As an electricity investment it pays back in about four years for daily users where power is expensive, as in Germany, and in around eight at US prices.
How the two models compare
| Inefficient | Efficient | |
|---|---|---|
| Model | Traditional electric sauna stove, 6 kW | Infrared cabin, 1.8 kW, short warm-up |
| Electricity per year | 2,190 kWh | 493 kWh |
| Cost per year here | $401.65 | $90.42 |
| Over 15 years | $6,025 | $1,356 |
Usage behind these figures: one session a day. Basis: Typical stove and panel ratings with a 45 minute preheat versus 10 minutes, at one session a day. The Electric Sauna Heater page prices the appliance at its own typical hours, which you can change there.

| United States (average) | $311.23 | 8.0 years | 8.0 years | Not for the electricity |
| United Kingdom | £446.65 | 5.6 years | 5.6 years | Worth it when replacing |
| Germany | €627.89 | 4.0 years | 4.0 years | Worth it when replacing |
| France | €339.57 | 7.4 years | 7.4 years | Not for the electricity |
| Australia | A$593.95 | 4.2 years | 4.2 years | Worth it when replacing |

Local electricity prices, with the same purchase price read in local currency, which is a simplification. The saving column is what matters: the higher the price of electricity, the faster any upgrade pays back.
