For years the people I was with and I just used the basement for extra storage; During the COVID lockdown there was a lot of free time to do household projects, so I took on the chore of clearing out the basement. There were boxes and bags down there from when the people I was with and I first moved in! Most of it went right into the trash bin. If I hadn’t needed it for almost a decade, why bother keeping it at all? When it was all said and done there was a important room open and waiting to be repurposed. The only thing keeping the section from being a Rec Room or a spare kitchen was the water boiler. The water boiler sat in the corner, and generated so much heat and moisture it would be taxing for the room to remain occupied for long periods of time. This was why it was being used for storage in the first locale, because the water boiler made it too moderate down there. In a fit of inspiration, I realized I could kill 2 doves with one stone and use the water boiler as the source for a lake beach house sauna. The water boiler would supply ambient heating and high levels of humidity, so if I could amp that up a little more the whole basement would be an amazing wet sauna. I called an Heating plus Air Conditioning professional to get his expert opinion, and he said the water boiler would be perfect for this idea; He did request a up-to-date humidity cut-off switch, so that if the air quality became dangerously damp the water boiler would turn off.
