3. True or false? The closer the distance between the UFH pipe work, the lower the heat output of the floor.


4. True or false? An increase in the thermal resistance of the floor covering, the greater the heat output of the floor.


5. True or false? An increase in the ΔT of the UFH system creates an increase in the flow rate of the water.
