I had an seasoned boiler idea in my basement.
Metal grates were all over my dining room floor.
The boiler would heat plus the moderate air would rise up through the grates. That is how my lower area of my home got heated. It actually was quite effective. The lake house felt toasty plus I never seemed to have chilly spots. I hated the look of those metal grates though. It was so ugly plus you were limited on where furniture went. So I covered up most of them but the main, central grate. When there was only one opening for heating, it was no longer as effective. I then was ready to toss the boiler once it died. After that the last grate was covered up plus I had a attractive dining room. I treated myself to a gas fireplace with a faux wood burning fire. It had a large wooden mantle plus a glass front. It actually was pretty. It wasn’t so fine at heating though. I had to get a supplemental oil furnace for the home office because it just could not do the job. The dining room consistently had chilly spots plus the heat actually liked to linger on the ceiling. It was kind of a pain… Now I am on my second furnace. When the fireplace died I ripped it out plus went back to a boiler system. Now though, I have piping within my floorboards. The boiler heats water that flows through the pipes for a heating effect, and you don’t see anything, but you think the heat. It is a way better way to provide heating in the home.
