How Much Water is Used?
Typically, a 5 – 10L bucket of water is suitable for a shower for one person. Recycling shower water is a smart trick for showering the family. Simply, stand in a big bucket while you shower with the inlet hose taking the run-off back into the system. This way you can cycle the water through the heat exchanger continuously. Soap suds etc do not damage the heat exchange unit.
How long your bucket of water takes to empty depends on the pressure that your pump delivers the water and if any flow restrictor is implemented on your shower head. You can do the maths by working out how many litres of water the pump is designed to deliver. Some water pumps are designed to deliver around 4 litres of water a minute (4 LPM), whilst others may deliver up to 7 litres per minute (7 LPM).
