2.1.3 Household hot water used
Pressing the up button from
cumulative carbon dioxide offset will
display “daily household hot water used”
(see figure 2.1.3). This is the volume –
in US gallons or litres, depending on
units of measure chosen (see section
3.2) – drawn for domestic hot water use
as read by the flow sensor on the cold-
water supply from mains. Figure 2.1.3
is an example of a reading (using US
gallons as the unit of measurement).
Pressing the up button again will show monthly (
) household hot
water used; press again for yearly (
), and once more for cumulative (
).
2.1.4 Water saved by displacing electricity generation
Pressing the up button from
cumulative water used will display either
“instantaneous power” (see section
2.2.8) or “daily water saved by
displacing electricity generation” (see
figure 2.1.4). Water saved by displacing
electricity generation is only available
when the fuel for the auxiliary water
heater is electricity, and will show before
instantaneous power. It can be
displayed in US gallons or litres,
depending on units of measure chosen
(see section 3.2).
The production of electricity requires water (see section 3.3.5). As fresh
water resources become more scarce and sensitive, it is important to use water
wisely, including directing it away from electricity generation. Water saved by
displacing electricity generation is the volume of water that is not used because
of the amount of electricity that is offset by the EnerWorks hot-water appliance.
Figure 2.1.4 is an example of a reading (using litres as the unit of
measurement).
