1. True or false? To conform to BS EN 1264, UFH panels that incorporate an aluminium layer as a conduction device, the aluminium must be foiled within the complete groove and in contact with the pipe.

2. True or false? The greater the temperature difference between the UFH mean water temperature and the air above, the lower the heat output of the floor.

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.
