Selecting the water heater
Hot water needs are not easy to assess, as they increase very
rapidly as users get used to this major convenience. As a result, the
recommended capacity should be much greater than existing
needs.

Selecting the location
Electric water heaters should be located in a place which is not
exposed to freezing, as close as possible to the various drawing
points, so that the piping is kept to a minimum length. If the tapping
points are very far from each other, it may be better to use two
water heaters.
While selecting the location of the heater, make sure that the cold
and hot water pipes are accessible and easy to connect.
