Saving electricity at circulation pump of the heating
A circulation pump ensures that there is always warm water in the line, so you do not have to run cold water unnecessarily for too long. However, as the water in the line does not cool down so quickly, it is sufficient if the pump is switched on and off every fifteen minutes. This works wonderfully with a timer, which contains in the circle arranged pins for adjustment. A pen for a quarter of an hour. So 15min on and then 15min off in alternation. Conclusion: Half the cost of electricity with almost the same effect.
