When laying out the tubing for a hydronic system, where should the supply line entering the room be placed?

  1. Along an interior wall

  2. Along an exterior wall

  3. Under the floor

  4. Above the ceiling

The correct answer is: Along an exterior wall

The supply line should be placed along an exterior wall because this allows for more efficient heat distribution. Placing it along an interior wall may result in uneven heating and placing it under the floor or above the ceiling would require more extensive installation and may not provide optimal heat distribution.
