Sauna Electrical Requirements

Sauna Electrical Requirements

PLEASE HAVE A LICENSED ELECTRICIAN WITH A COMPLETE KNOWLEDGE OF LOCAL CODES DO ALL OF THE WIRING FOR THE SAUNA.  And please follow the specific heater manufacturer’s installation instructions that arrived with your heater.

Here is some helpful information to pass along to your electrician in order to get your sauna up and running:

The sauna heater will require 220v and must be hard-wired to the electrical box.

If your sauna comes with a 4.5kw or a 6.0kw heater, it will require a 30-amp breaker and 10/2 wire, unless it is positioned more than 30 feet from the breaker in which case it will require 8/2 wire.

If your sauna comes with an 8.0kw heater, it will require a 40-amp breaker and 8/2 wire.

Your sauna also comes with a light that will require 110v power with 15-amp service, and your electrician can wire the on/off switch inline wherever you choose.  For example, if you have an outdoor sauna, you may wish to have the switch positioned closer to your house so you can flip it on your way to the sauna.  We don’t recommend placing the switch inside the sauna room.  If that’s something you’d like, it is possible to upgrade to a light with an integrated switch.

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 through this hole.  In a barrel sauna, it can also come up through the floor below the heater.

Heater owner’s manuals can be found on our website, or you can contact us and ask us to send you one.

How efficient are the sauna heaters?

Because they run on 220v of electricity, draw less than 40 amps of power, and are constructed from high-grade sections of softwood that are almost an inch and a half thick and provide excellent insulation, Almost Heaven Saunas are quite efficient.  Good news for your energy bill.

How long will it take to heat up?

Heat up time is largely dependent on the ambient temperature surrounding your sauna and your desired temperature.  It’ll heat up faster in, say, 75F versus 35F weather, and it’ll heat faster to 160F versus 190F.  However, a good rule of thumb is that the sauna will reach 165F in 30-40 minutes and 190F in less than an hour.
