Description
The Harvia Vega Compact 3.5kW is a wall-mounted stainless steel sauna heater with built-in controls, sized for small home saunas of 70 to 175 cubic feet. The operating switches sit at the top of the heater and can be placed on either side, and the heater can be mounted low so the lower benches also get good steam. It is designed, engineered and made in Finland.

- Sauna stones are sold separately. The heater needs a minimum of 29 lbs (1 box of AC3000). Natural stones vary in shape, so some owners order an extra box to pick the best fit.
- Harvia notes that correctly loaded and maintained stones are part of the heater's safe operation and are required to keep the warranty valid.
