Did you guess that your boiler could connect to radiant floors? I had no plan that this existing until a week ago. I did some research online about our old boiler system. The boiler had been in our house for years just heating our home. I then heard the boiler could do so several more things besides house heating. After researching, I found hydronic heating. How this works is connecting piping to the boiler. The boiler heats a bunch of water & pushes the hot water through the piping. The piping is installed within the floorboards of the house. The warmed up piping is what creates radiant floors. How awesome is that? Apparently hydronic heating is very efficient too. I have only had our hydronic gas furnace for one week. So I have not seen savings yet. But, according to what I have read, the gas furnace is not care about a gas furnace. With a gas furnace, the heated air rises to the ceiling since hot particles are lighter. With radiant floors, the hot air stays at the lowest level. Since your lower body is consistently warm, you believe naturally warmer. This means you are able to set your thermostat lower. Lower thermostat means less heating needed & this means lower bills. Also, with hydronic heating, everything that touches the floors absorbs the heat. So the couch, chairs & table all believe heated with this system. I have noticed this personally. So far, after only a week I care about our heated flooring system. I can’t wait until the radiant floors save me currency too.
