How do I determine the size of the heater?

Take L x W x H to calculate cubic footage, and then find the correct heater on the Finnleo or Helo heater sizing chart. On the infrared saunas, the correct amount of emitters and wattage has already been determined and maximized for each room.

What type of circuit breaker should I use?

Standard breakers, properly sized for the heater according to the National Electric Code. For the standard Infrared saunas, they can be plugged in to normal household 120 volt outlets (15 and 20 amp).

Why do you recommend so many different wood choices?

Woods are determined for multiple reasons. The main reason is performance. All the woods we use in our saunas have been used for centuries in sauna use and have long proven their viability for sauna use. The main reason for wood choices is user preference and style. We hand select clear softwoods such as Western Red Cedar and Canadian Hemlock (vertical grain only) and European fine grained woods such as European Alder complemented by matching bench materials which enhance the user experience and comfort. We determine the best profiles, thickness, framing materials, hardware and provide you with a product that is built to last. Our warranties and decades of experience confirm our leadership in this regard.

No. Only an authorised person is allowed to connect a sauna heater to the electrical network, according to the electricity regulations in force.

Is it wise to use thin insulation?

It is never wise to save on insulation, as a change will affect the output selection. Pay special attention to the ceiling. We always measure saunas fully thermally insulated. When using a Sauna-Satu, for example the minimum requirement is 60 mm in the walls.

When resetting the stones, broken and sand-surfaced stones are removed and replaced by new ones. This does not apply to sauna heaters in institutional use!

How do I calculate the sauna volume, when installing an electric sauna heater in the sauna?

Multiply the height by the width and length. Add the volume of cold surfaces to the previous result: i.e. calculate the stone and glass surface are and multiply by 1.5.

Time and Money

What is the average cost to operate?

If used 3 times/week, a 6 kW heater will use about $4 to $6/month. A 2.1 kW heater would use about $2/month. For Far-infrared, the typical sauna uses $3 to $5 per month. Steambaths average $3 to $5 per month.

What is the average heat-up time for a sauna?

A traditional sauna typically heats up in 30-45 minutes. During this time period the rocks will be properly heated for soft heat and soft steam – and the wood interior will be comfortably heated, too. With the addition of a Saunatonttu heater heat up time is cut in half. On the infrared side, most bathers find that a 10 minute wait is about right. By then, the air has warmed up a little and the emitters are running at full power.
