Am considering buying this sauna. How long does it take to heat? Does it get really hot on regular 110v?

Hello EGH, we are now using a Harvia JM20 110 volt heater. The sauna probably takes about 20 to 25 minutes to get up to the max. temperature and that top temperature is about 180 to 185 degrees F. This heater will require a 20 amp outlet.
