Fahri, I would not expect the heating demand to be the same between the two. The ideal heating type does not take into account any of the inefficiencies of delivering energy to the space. It is simply a measure of the amount of energy that has to be put into the space in order to maintain the space at a desired temperature. When you look at the floor heating component, you have now introduced an inefficiency of the energy transfer from the water to the layer in which the pipes are embedded and you have introduced a somewhat uncontrollable energy storage into the system. I would imagine that the difference between your two numbers was largely because of the energy required to heat up the concrete before it can effectively transfer energy to the zone.
