Water Heater: Tank or Tankless?

August 27, 2008 by · Leave a Comment 

This article, posted on the NKBA website, summarizes the differences between the standard tank and tankless water heaters.  The article is authored by the folks at Rheem.  In the article, Rheem is unveiling a new website “to provide straight talk on tankless vs. tank water heaters, aimed at helping construction professionals advise their customers which system is best for different circumstances.”

Also from the article:

Rheem summarizes some of the differences:

* Product Cost: Tank water heaters typically range in cost from $350 to $550, while tankless water heaters are roughly double that amount.
* Operating Cost: Average annual operating costs for tank water heaters are in the $230 to $285 range. Average annual operating costs for tankless water heaters are about half of that, at $165 to $170.
* Installation Cost: In new construction, installing any type of water heater includes running fuel lines or electrical connections and allowing for adequate venting, so there is little difference in costs between a tankless water and a tank water heater. In remodeling, however, it will cost more to replace a tank water heater with a tankless unit. Installed costs to replace a tank water heater with a tankless unit are typically between $1,200 and $3,000, compared with a range of $500 to $800 to replace a tank with another tank.
* Size: Tank water heaters are typically four to six feet in height, and up to two and a half feet in diameter. Because of their size, tank water heaters are usually located in the garage or basement, which sometimes places the hot water far from the point of use. Tankless water heaters, about the size of a medicine cabinet, can be wall-mounted indoors or even outdoors.
* Experience: Tankless water heaters never run out of hot water. A properly sized unit allows for use of multiple fixtures and appliances at the same time. Tankless is especially ideal for luxury spa bathrooms, where one large whirlpool tub can empty a 40-gallon tank-type water heater before the tub is even filled.

While the site is open for all, including homeowners, Rheem offers a white paper and bi-monthly newsletter that is strictly limited to professionals. For more information, visit www.smarterhotwater.com.
