Installing radiant floors in a genuinely old condo

I am coming close to being finished making the near impossible happen, and i had been completely restoring this genuinely old apartment built in the 1960’s with modern everything! I redid the windows, the rooms, & I even got all modern flooring put into the place. The last touch was to install radiant radiant floors into the home’s kitchen. The residing room is being heated by space furnaces for now. I had thought about getting central heating & a/c, but I am trying to keep the costs down in terms of energy use, then for the kitchen, since it’s the only place other than the bathrooms that are tile, I figured that radiant radiant floors would be the best rout to go in terms of heating. I am having a small time heating & cooling local corporation take care of this task, & I am paying him well to do so. Though, he said that the tiles have to be completely replaced first. This is the only thing from the original flooring of the condo that I have not yet replaced. I had originally thought that because it was tile, that radiant radiant floors would work & be enjoyable with the old tile. The heating & cooling specialist said I was genuinely wrong on that assumption. It had something to do with the make of the cement & mixing it with the radiant heat that would be coming up from the radiant radiant floors. That will be done in the next week. Then, all is done & a crucial success! I can’t wait!
