Heating System Simulation – Part 4 of 4


Once the phenomenology of the radiators was analyzed, the possibility of finding better alternatives was raised. The following graph shows the different temperature curves from floor to ceiling in a house depending on the heating system that is used.

From these curves, it is deduced that apparently radiant floor heating is a better system than by radiators, and for this reason it was decided to simulate the radiant floor heating system in the apartment.


Temperature curves

The results of the simulation of the underfloor heating are clearly shown in the following images.

In the image below, a cut made at the height of the radiators was shown.

At first glance, differences from the radiator system can immediately be seen.  There are far fewer cold spots and the average temperature is higher—although it is true that the temperature in the living room is still lower than in the other rooms.

In the image below shows a cut at 2 meters high and, as you can see, the temperature is very similar to that of the image on the left and, therefore, the stratification is eliminated and the comfort of those living in the home is improved.

In the following image, you can clearly see the difference between radiator heating (images above) and underfloor heating (images below) as far as stratification is concerned.

The air from radiators is warm at the ceiling and cold at the floor. Also, currents of air are produced that can cause discomfort on certain occasions. On the other hand, the radiant floor heating creates an air area with a more uniform temperature throughout the whole height.
