After a lot of research, I settled upon a heating system that leverages a hot water heater to circulate heated water through plastic pipes that I laid within the slab. It’s highly efficient and creates a gentle, even heat throughout the space. For the second floor, i added a second zone with slightly cooler water to be compatible with the engineered floor that will be laid above it. It was highly labor intensive but in the end really worth it.
