Dear Eastside,
I just wanted to thank you for a job well done.  You have serviced my personal heating needs for years.
You will continue to receive my business because you have always provided timely and professional service.  I think one of the most important assets I have is a group of people I can count on.
Keep up the GREAT work,

Rinnai Tankless Water Heaters Portland Oregon

The Rinnai LS Series

tankless water heater

is a state-of-the art, energy-efficient water heating system that uses a gas-powered heat exchanger to heat water. The Rinnai LS is the perfect choice to supply all your hot water needs. And unlike traditional tank systems, the Rinnai system can deliver hot water to multiple water sources simultaneously at a constant user-set temperature.

Compact in size, LS Series interior wall-mount units can be placed in any room - no need to hide them in closets or utility rooms - and vent directly to the outside. Exterior units require no additional venting and can even be installed in a recessed enclosure, then painted or textured to match the exterior of your home for a clean, inconspicuous appearance.

Rinnai models are available in natural gas or propane gas units that deliver up to 9.8 gallons per minute (GPM) of continuous hot water with 15,000 to 237,000 BTU heating capacity (R98LS models). They feature a direct energy-saving electronic ignition. No more energy-wasting pilot lights. Interior mount units require no indoor make-up air and vent directly to the outside atmosphere.

With the newly designed commercial-grade exchanger, the same LS unit can be used for both residential and commercial applications. Homeowners get the reliability of commercial-grade construction and an industry-leading, 12-year limited warranty, and commercial customers get lower cost and wider availability of units.

APS (Air Pressure Sensor) maximizes combustion efficiency by sensing and controlling the air required for optimal combustion even in high-wind locations and installations with long vent runs. Advanced Technology Water Heater Portland Oregon
APS and GPS sytem accompained Water Heaters Portland Oregon

GPS (Gas Pressure Sensor) offers stable combustion by sensing gas pressure and controlling the fan speed to maintain optimal combustion, even under a wide range of gas-pressure changes.
‡B Three-phased, Pre-Mixed Burner
Controls flame by pre-mixing optimal ratio of gas and air before combustion, reducing emissions and enhancing heat efficiency.
‡C Leak Detector
Built-in leak detector prevents damage to water heater as well as personal property.
‡D Air Intake Filter
An air intake filter prevents foreign substances, such as dust or insects, from entering the system, freeing the burner from elements that would normally cause unstable combustion or energy inefficiency.
