Saving Heat Investments
Shower 5 minutes instead of 10 minutes. The consumption for a normal shower is 10 liters per minute. If you can shower within 5 min., you can save 5*10 ltr/min with a normal, not wasteful shower. If you have installed a low-flow shower which consumes only 5 ltr. per minute you can save 5 min * 5 ltr/min. If you shower every days, this is equal to 18 m3/year and 9 m3/year, equal to 950 kWh/year and 475 kWh/year. In Denmark there was a rap music sang was made to promote to use lass shower time.
No cost.
