How to get thinner floors?
We have three 1st floor rooms that we want to convert to radiant floor heat. The house is being restored, with the remaining hot water radiators being replaced with low-water Euro units. ( most of the cast iron was broken, but the pipes hold pressure )
One is a bedroom, where the original wood floor had to be ripped up exposing the subfloor from 1930. The bathroom was gutted for minor enlargement so the subfloor is gone ... bare to the joists. The kitchen floor is old linoleum tile, over plywood, over subfloor.
The plan is to do radiant heat & tile floors in all three, but matching to the existing floors seems to be a problem.
One prospective contractor suggested using rock-board, or Hardie-board, or a similar product over the pex panels on top of the subfloor ( instead of floating in a layer of mix ) and then attaching the tile to that board. Would that work? 1/2 in. board minimum?
Would we be better off tearing out the rest of the subfloor and starting from the joists?
The kitchen has two outside facing walls ( brick ), plus a large window ( being replaced with a double-pane ), and a porch door with 12 glass windows ( plus a storm door ).
There might not be enough floor to heat it with radiant one the cabinets are installed, minus the space under the refrigerator.
Comments or suggestions are certainly appreciated.
