Editorial correction: This guide uses manufacturer documentation. ThermalFinn has not performed firsthand heater testing. Unsupported measurements, rankings and universal installation prescriptions from earlier versions have been removed.
Compare the Installation Before Choosing the Fuel
The useful starting point is the equipment that can be installed in your proposed room. ThermalFinn has no controlled wood-versus-electric performance dataset. The previous numerical winner, heat-up comparisons and claimed practical testing have been withdrawn.
| Decision | Electric heater | Wood-burning heater |
|---|---|---|
| Infrastructure to investigate | Compatible electrical supply and control package | Compatible chimney, flue route and stove installation |
| Documents to obtain | Exact regional heater and controller manuals | Exact stove and chimney instructions |
| Quote to request | Heater, controls, stones and electrical installation | Stove, stones, chimney components and installation |
| Costs to record | Measured electricity use and your tariff | Actual fuel purchases and maintenance costs |
Check the Proposed Location
Harvia’s wood-heater selection guidance explains that chimney position affects stove placement. Obtain a model-specific plan for the stove, chimney, clearances and surrounding construction before ordering. Have an appropriate installer confirm local requirements and whether the planned location is suitable.
For electric models, identify the exact regional electrical version and compatible controller. Use the electrical planning checklist to prepare information for an electrician. Do not assume a circuit specification from heater power alone.
Compare Everyday Use Without Invented Scores
Ask how each model is started, controlled, maintained and serviced. For a wood stove, review its fuel and operating instructions. For an electric heater, review controller features and any restrictions on remote operation. Choose from documented features that fit how you intend to use the room.
We do not claim that either fuel type produces a measured steam-quality advantage or a guaranteed heat-up time. Room construction, installation and operating conditions matter to any meaningful comparison.

Use the same room plan for both proposals and identify excluded work. Compare delivered equipment and installation totals, then record actual operating costs rather than projecting them from unsupported efficiency percentages.
Continue with electric heater comparisons, the room-sizing guide or the complete-cost checklist.
