Models review

Rinnai V75 water heaters are coming from the "Value" series
that is recommended for budget-oriented families, who would like to
replace the old tank-type water heater as the retrofit or installing in
the brand new home. These models offer on-demand water heating
in residential and manufactured homes and are providing a continuous
supply of
hot water. V75 models are using both natural and propane gas for
heating and are Energy Star approved. The heaters are
recommended for heating water in homes with up to three showers.

The warranty is 10 years on the heat exchanger or 12 with the
isolation valve kit installed.

Rinnai V75i

Rinnai
V75i is
an indoor model that uses the direct venting system and
the forced combustion. That means, the water heater uses the outside
air for gas combustion, while safely moving the products of combustion
out. As it is designed with the closed combustion, V75i is suitable for
closet, attic and crawl space installations.

Rinnai V75e

Rinnai
V75e also
uses the forced combustion but without the
venting pipes as it is installed outside. This type can be installed
either on the external wall or in recess box, which protects the unit
from the harsh weather.
