Masonry Mass Stove Workshop, Southern Wisconsin, May 1-4

Hello Essa,
We still have a few spaces in our masonry mass heater workshop this May. These are super efficient heaters that have been used for hundreds of years to heat interior spaces with constant, radiant heat. See the flier below and follow this link to learn more: https://lowtechinstitute.org/2025/02/27/masonry-heater-workshop/



Thanks and please feel free to pass this on to anyone who might be interested!

Cordially,
Scott
