Description
Small 3.6 kW electric heater with integrated control from Austria
This unit is the entry-level model from the Austrian manufacturer Sentiotec (a Harvia brand): a 3.6 kW electric heater whose control is part of the housing itself. It is intended mainly for small Finnish saunas and runs from an ordinary 230 V socket.
Why it is worth it
- 230 V / 50 Hz supply – no three-phase installation needed
- The control is built into the unit, with no extra cabinet
- Clockwork timer for operation of up to 4 h
- Small, light housing – 8 kg
Timer and safety
The timer has two modes: an immediate start with operation of up to 4 hours, or a delayed start after 1 to 8 hours, again with operation of up to 4 hours. For protection, the heater has a thermostat with a safety cut-out set to 110 °C.
Heat-up and housing
The housing is made of galvanised steel, and its collar is made of polished stainless steel. As a guide: in a Heikki sauna, a temperature of 80 °C is reached after about an hour. The internal parts are made of corrosion-resistant materials.
