Flooring – How many “zones” should the underfloor heating system have

flooringheating

We're putting underfloor heating in our new apartment. On top will be a wooden floor for most of the apartment, stone/tiles in bathrooms and probably also in part of kitchen.

The constructor said that three zones would be enough:

  • Red zone (office and dining room)
  • Yellow zone (entrance, kitchen and large bathroom
  • Green zone (bedrooms, hallway and small bathroom)

Is this a fair and sufficient distribution of zones?

Usually 3 zones is plenty for a single story structure of this size. In this case I think your contractor has given you good advice. The distribution is to like living areas which is good. Obviously, more zones allow more flexibility and control, but the costs of equipment and labor rise as more zones are added.
