Do not buy a HUUM sauna heater! There are much better heaters backed by reliable companies out there. HUUM is a shady company based in Estonia. If you have ANY problems with your heater, they will not repair or replace it, even if still under their 1-year terms. I have personal experience and lost out on a $3k investment. Instead buy a Harvia or Finlandia, companies with much more experience and a track record of taking care of customer
