I am moving into a new house that has underfloor heating (wet system) throughout the ground floor.
I am trying to decide what flooring material to use. (tile or wood)
I know that tile will be a better material, as it will allow heat to pass through more easily. My understanding of this is based on the materials R value
But I am wondering how can I calculate, or even roughly know, how a materials R value will affect the heating costs?
For example, given these values, (both 7mm thick)
- 0.02 -> Ceramic Tile
- 0.25 -> Engineered Wood
Does this mean tile is ten times faster to "feel" hot? i.e. if it takes 10mins to heat tile surface to 12C, will it take 100mins for the wooden floor?
Or is R value simply not important or not a good indicator of heating times or potential heating costs?
