Harvia's Spirit series digital sauna heater, made by Harvia in Finland, is a traditional Finnish-style wall-mounted sauna heater. The Spirit is a cutting edge design that reaches high temperatures, and generate lots of steam. This heater showcases the round sauna stones which creates a modern yet elegant atmosphere in the sauna without abandoning the traditional sauna experience.

This digital sauna heater is operated by the touchscreen control pad which mounts outside of your sauna. Harvia's new digital control pad is WiFi ready, which means your sauna heater can also be controlled from your smartphone by downloading the MyHarvia app. 

If this product is installed outdoors, the power unit and touchscreen control panel must be housed in weatherproof protection. Weatherproof boxes are not included with the product and should be sourced locally by your electrician. Any damage to your equipment resulting from failture to install the power unit and control panel in weatherproof protection will not be covered by Harvia under warranty and will have to be replaced at your expense. Please note the weatherproof box for the control unit should be ventillated at the bottom to allow for cooling. 

Electrical Requirements

All electrical wiring must be performed by a qualified and licensed electrician with complete knowledge of local codes and regulations. 

This sauna heater will require 220v and must be hard-wired to the electrical panel. The 8kw digital heater will require a 40-amp breaker and #8 copper wire. The 6kw digital heater will require a 30-amp breaker and #10 copper wire, unless they are positioned more than 30 feet from the breaker. In this case, they will require #8 wire. For this digital heater, the power from your electrical panel will run to the power unit box (see diagram below) which must be positioned outside of the sauna, but within 13 feet of the sauna (due to the temperature sensor cable length). The Harvia power unit is not weatherproof and must housed in weatherproof protection or located in a dry area. The power unit feeds power to your sauna heater, temperature sensor and the digital control panel via separate wires and cables. The digital control panel must be positioned within 16-1/2 feet of the power unit box. The digital wall control must also be outside of sauna and housed in a weatherproof box.

Your electrician will drill a hole in the wall of the sauna below the heater for the conduit. All of the wiring will come into the sauna from the power unit through this hole.

To make the connection to your power unit, your electrician should use copper wire with 90C insulation. Do not use aluminum wire to make the connection. Consult with an electrician so you can determine the requirements for your particular situation. All wiring must conform to all national, state, and local codes and regulations.

Because our saunas run on 220v of electricity and draw less than 40 amps of power they are quite energy efficient and should not be a significant drain on your electricity bill.
