" BURBANK, Calif. -- The staff here is always looking for ways to be more efficient, even if they&amp;#039;re relatively small. So Jay Leno invited the folks from A.O. Smith Water Heaters recently to bring their new, high-efficiency Vertex water heater to the Green Garage. Actor and environmentalist Ed Begley Jr. came along to check out the installation, as well as  to his garage. Ed was certainly impressed with the work so far, and he&amp;#039;ss exited about this water heater, too.  A.O Smith brand manager David Chisolm and Bateman Water Heating Engineering&amp;#039;s Scott Bateman explained that the Vertex isn&amp;#039;t just a regular gas water heater: It generates a whopping 76,000 BTUs per hour, but it&amp;#039;s also 90 percent efficient. Most home water heaters in service today are around 78 percent efficient, and tankless models are 80 percent efficient. The key to this unit&amp;#039;s performance is in the coil. Inside the tank, the Vertex has a &amp;quot;helical coil&amp;quot; heat exchanger, which essentially has an increased surface area exposed to the water compared to a conventional heater. This helps produce more hot water, more efficiently, and at a lower cost. The Vertex is said to produce as much hot water as much larger models and claims to provide a continuous flow of hot water--enough for hot shower after hot shower. A.O. Smith says home owners are saving up to 30 percent on their hot water utility bill. Sounds good to us.
