Lifetime warranty water heaters from Marathon:

• The most durable water heater made
• Envirofoam™ insulation is completely free of CFC and HCFC ozone depleting gases
• 6-year element and thermostat warranty from date of manufacture
• Highest energy efficiency rating
• Designed for easy installation

• Carbon monoxide is not a problem with an energy efficient, electric Marathon
• Warranty for non-residential use is 15 years

Why should I bother, my last water heater lasted 22 years? Older water heaters had much thicker steel and more porcelain than today's units. Because so many costs have been cut from the manufacturing process, most steel water heaters made today will not last much longer than their warranty.

Wouldn't gas be cheaper in my new house? Not necessarily. Although gas may be slightly cheaper, gas water heaters are more expensive than electric units and the venting now required for safety can be quite expensive.
