Taking a shower is more economical than taking a bath in a half-filled tub

True
If you have a low-flow shower head (5.7 litres/minute), you would have to stay under the water for 21 minutes to use the same quantity of water as if you filled the tub half-full. And 21 minutes is a long shower, as well as a huge waste of water! You’ll save even more water if your shower takes less than 10 minutes!

The direction in which a ceiling fan’s blades turn has no importance.

True

False

4 of 12

The direction in which a ceiling fan’s blades turn has no importance.

False
It comes down to science! In the winter, the blades should turn clockwise so that the cooler air is pulled upwards to the ceiling. The warm air, which tends to accumulate near the ceiling, is then pushed downwards and able to spread through the room. For the best results, the fan should run at low speed. Conversely, in the summer, the fan should push the air downwards to create a cool breeze. In this case, the blades should turn counter-clockwise. Check out your own fan to see what direction it’s turning!

To reduce your pool’s energy consumption, use a solar pool cover and a timer with your filtration pump. Enjoy your swim!
