<p> It would help to know....is this duplex already
built? and considering where you live, is a woodstove being
considered for space heat?</p>

Wrenches,<br>
<br>
Is there a good way to estimate the power that will be consumed
for electric water per person per day? We are estimating the
amount of power that will be used by an all electric duplex, and
the water heater amount seems high. The current model we have
claims 3493 kWh/ year per 26 gallon tank will be consumed. With
the two units, that would add up to 6986 kWh / year for hot water,
pushing the system size to humongous for a 1300 ft sq building. <br>
<br>
Does that seem high? There will be a maximum of 2 people per unit.
<br>
<br>
The owner is considering going to 115 V units with a 15 gallon
tanks. I think the smaller tank would help, but it would seem that
the amount of hot water consumed would be the main issue. <br>
<br>
How can we get a good estimate for a per person energy usage for
electric hot water? Any other suggestions are welcome.<br>
<br>
Thank you,<br>
<br>
Drake<br>
