Winters can be harsh and one of the problems with the winter being freezing is that people feel cold in their own homes as well. This is why adequate floor heating is needed to warm the room from the bottom up.
The idea behind generating heat from down upwards is that it also warms your legs, which can get cold easier. Once the floor is nice and warm, the warmth will spread higher up the ground as well to other areas of the room. Once the bottom area is warm, the air will mix up easily with the cold air from above so that gradually the entire home gets nice and warm.
The air gets easily distributed pretty much everywhere and once warm, it stays that way for a longer time than when using traditional heating sources.
While people have recently started using this type of heating, it is not a new concept at all. It has been first used during the Roman Empire when people were using water hydraulic pumps to bring water up from below the ground. You had pipes attached to the pumps so that the water would be pumped upwards through the pumping mechanism which would push it through the pipes. The water was getting heated and it would pass through the actual floors. This heat was generating a nice warm floor that would warm up the air around it as well.
It took a while to perfect this method and early on it did take quite a lot of time to get the room warm, however these days there are very easy floor heating devices that can make the room warm in a jiffy. You can find currently electric heating mats that you put under your flooring for fast warmth spread over the entire floor. This is using the power supply at home and this means that you can easily connect it to your home electricity supply.
As for the installation, it can be done quite fast, much faster than in ancient times. Within a day the system is up and running without having to reinstall any of your flooring in the process. And when it comes to how much electricity you are consuming, that is hardly worth mentioning as it doesn’t consume all that much either.
