Did you know that the water heater in your home is the number two consumer of energy, yet design and development is virtually unchanged since your grandparents drove a Model A? In America we continue to heat water 24/7 365 days a year only to be used on an average of 70 minutes per day based on a home of 3.5 occupants.

This unit was installed in the attic of a small bungalow. An old tank water heater was in a closet in the kitchen. The reclaimed space is now used as a broom closet.

Storage tank water heaters consume about 10 sq ft of floor space and have an average life in the Tri County area of approximately 13 years. During this time the efficiency is dropping due to mineral and rust build up in the tank.

Leaking and ruptured tank type water heaters cause millions in damage to homeowners and are listed as number two in homeowner’s insurance claims behind washing machine hoses.

With energy cost in the United States continuing to rise as we compete in a world economy for energy, economics has mandated we become more efficient in our homes, autos, and industry.

One way of making our homes more efficient and less costly to maintain is to convert our water heaters to what the rest of the world has used for 75 years, tankless or as it is more commonly referred to “on-demand water heaters.”

In the domestic market you will find four major manufacturers, Bosch, Noritz, Rinnai, and Takagi of which all are built of similar materials (copper, brass, stainless steel) and quality workmanship. These are high-end; high-performance category III appliances designed to last 20 years or longer.

Of the four major manufacturers mentioned above Rinnai stands alone with zero clearance with the direct vent unit model 2520FFU. It is the most versatile unit available. Rinnai, the largest manufacturer of gas appliances in the world has developed a vent system that allows installation of gas water heaters in areas, never before used such as attics, crawl spaces, and bedroom closets and kitchen cabinets. Combustion air and exhaust gases are handled through a zero clearance concentric pipe. This design reduces labor resulting in a savings to the homeowner, and also provides a safer venting system. Utilities, major retail stores, HVAC contractors as well as Paul Harvey endorse Rinnai products.

In Oregon you can receive a $340 tax credit for a tankless water heater.

Look for tankless water heaters to become required in new residential construction in the next five to seven years.

Tankless Advantage:
1. Uses 50% to 70% less energy.
2. Consumes about 2.2 cubic feet of space allowing for
installation in spaces with limited area.
3. No storage tank so there is no accumulation of depositsof rust and no consumption of energy 24 hours a day, 365 days a year.
4. With an electronic pilot light, computer modulated
burners use only the gas needed to supply demand.
5. Capable of water flows ranging from 0.5 to 6 gpm with heating capabilities of 20,000 to 185,000 BTU
6. Computer is constantly monitoring internal operations with system of circuits and sensors checking for over-or under-heating, freeze conditions, gas levels, water levels, intake air, and venting conditions.
