Water tank pump
From Greenlivingpedia, a wiki on green living, building and energy
Water tank pumps are quite efficient and don't use much power to operate.
[edit] Example 1 - water pump for all household water requirements

Surrey Hills house water tank pump
For example, sample measurements from a pump operating for the Surrey Hills house supplying all water needs in August 2008 were:
Hours | 297 |
Days | 12.375 |
kWh | 2.8646 |
kWh/h | 0.009645118 |
kWh/day | 0.231482828 |
[edit] Example 2 - water pump trial for garden watering
This trial was conducted with a water pump used to water a garden, also in Surrey Hills, Victoria. The pump was run for 20 minutes, the volume pumped and the electric energy used were both measured.
Volume pumped - litres | 608 |
Energy used - kWh | 0.35 |
Water usage per day (2 person household) - litres | 122 |
kWh/day | 0.070 |
