Unit C Introduction: Heat and Temperature
Figure C.I.1 – A very mysterious method of heating.
Figure C.I.2 – A worker installs in-floor heating.
An Innovative Way to Heat Your Home
The image in Figure C.I.1 looks like a strange puzzle. Can you guess what it is? Think about the last time you stepped onto a cold floor in the morning with your bare feet. Nobody likes to stand on a cold floor, and it can take a long time for the floor to warm up. If the floor is in the basement, it might be cold all the time, and especially so in winter. It sure would be nice if there was a way to make the floor warm!
It turns out there is a very good way to heat your floors, and the technology can work to heat your whole house too. It's called in-floor heating, and it works by running pipes carrying heated fluid in your floor. The great thing about in-floor heating is, not only does it keep your toes warm on a cold morning, but it costs less to operate than traditional means of heating a home. Depending on the heat source, in-floor heating can be more environmentally friendly too.
