Hi Everybody,
Well, price for all energy sources is going up.
What would be the more efficient way to run water heater?
1. Decrease hot water temperature to acceptable minimum.
Assuming recovery time is also acceptable and heater will
be able to provide enough hot enough water.
This way heat loss will be minimal during the time when
there is no water use at all (most of the day time, except for
weekends and holidays and night time) but heater will be
running all the time when water is actually used.
2. Increase hot water temperature to the allowed limit.
In this case temperature control mixing valve must be installed.
This approach will minimize hot water usage and heater run time
should be less (I am not sure about this?) but heat loss will
be higher due to the grater temperature difference.
Theoretically (in ideal world without losses) there will not be any
difference at all. But in our real life it must be a difference.
What do you think?
Thank you,
