Is an Efficient Electric Sauna Heater Worth It in the UK? (2026)
With electricity at 26.3p per kWh in the UK, replacing a working electric sauna heater takes 5.6 years to pay back, which is slow. When yours needs replacing anyway, the extra cost of the efficient model comes back in 5.6 years.

| Scenario | You pay | Payback | Net over its life |
|---|---|---|---|

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 | £576.41 | £129.76 |
| Over 15 years | £8,646 | £1,946 |
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.

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.
