Tankless Water Heater
R75LS
models
Rinnai R75 LSi and LSe main features and benefits
There are two Rinnai tankless water heater R75LS models; Rinnai R75LSi and R75LSe model; both of them supplying up to four hot water units simultaneously, with 7.5 gallons per minute and 180 000 BTU per hour. Both on demand Rinnai models are whole house units using natural gas and propane - LP gas for heating.
Rinnai
R75LS models are very attractive with its silver metallic and shiny
look so you can
put them anywhere inside your home, and if your kitchen is equipped
with the stainless
steel appliances, it's a perfect match. I would say, hidden in a closet
is
not the right place for such contemporary designed Rinnai
water heaters.Rinnai R75LS models are selling as the "luxury models" designed for medium to larger homes and if you need a water heater that has a higher capacity.
Rinnai Tankless Water Heater Feature Review
Rinnai is green.
Rinnai on demand water heater, when comparing to standard water heating units is advanced in protecting environment as it produces less greenhouse gases like NOx and CO2, making it a green water heater.Quality components.
Heat exchanger on Rinnai R75LS
models is
commercial grade unit, made of copper, resistant on
corrosion and reliable on high temperatures. Warranty on heat exchanger
is 12 years (residential use), while on other replacement parts is 5
years and one on
labor. Based on many user reviews and plumber feedback, these units are
truly durable; their life expectancy is 20 years and over.Rinnai water heater is using electronic ignition to fire gas, not an energy consuming pilot light that is burning even when there is no need for hot water heating.
Easy installation.
Installation of the digital controller is highly recommended so you can set hot water temperature as you wish and within a specific range and with an error code indicator you can diagnose and troubleshoot any problem. These digital controllers are standard equipment on all Rinnai tankless water heaters.For large homes, offices or restaurants, two Rinnai tankless hot water heaters can be connected by EZConnect cable, so they can work as one unit, providing much more thermal power and hot water.
Rinnai is high efficient.
Both Rinnai gas heaters R75LSe and R75LSi, are Energy Star qualified with the energy factor 0.82 for both propane and natural gas use. Tax credit up to $300 and other local rebates are available.Safety features

The main competitors in tankless water heating industry, in US and Canada are Noritz, Bosch, Paloma, Navien, Takagi and Rheem.
Rinnai R75 LSe or R75LSi
Rinnai
R75LSeN
model
has a
great advantage being an outdoor unit so you don't have to worry
about possible gas leak, venting system installation, flue gases, water
leaking, or finding the right spot
for its installation. Even hanging outside they are still able to provide sufficient hot, potable and clean water, with a consistent and safe temperature, for two to three baths home or any other application in residential and commercial use.
If
you decide to buy
Rinnai interior model R75LSi
you have to provide the appropriate venting.
Rinnai R75LSi can be installed virtually anywhere for domestic
water heating as it
is designed as combustion sealed water heater.Flexible unit installation with concentric venting system is such an easy solution. This Rinnai model is using direct vent system where one concentric pipe is used for air intake and for venting gases out.
Rinnai vent kit has to be original, without any modifications on the pipe, like reducing the pipe diameter, and to vent directly outside through the wall, without any connections to the existing vent or chimney.
To prevent condensate draining back into the water heater through venting system, an integrated condensate collector is used to protect the unit with the proper installation (angle) of the flue pipe.
Either way you go, interior, direct vent or exterior installation, Rinnai tankless water heater, from series R75LS, is designed not to lose any performance, to be safe for your family and to be used even for hot water heating application up to 10 000 ft or over 3000 m above the sea level.
