A: The main difference is one has a tank, and the other has no tank. That is obvious! Now let's shed some light on the subject. Lets say you already have a tank water heater, and you want to replace it with a tankless model. Location is the key. If your water heater is in the garage, or the attic, there are certain disadvantages, associated with

Isn't a tankless water heater instantaneous? Tankless water heaters use less energy so they cost less to operate. I think most folks these days go with tankless water heaters.

you will need a circulation pump instaled for each room you want hot water instantly . otherwise it will take the same amount of time wether you go tank or tankless.

Other considerations are that a tank heater has the advantage of a place for sediment and residue to lay, while a tankless will let anything get into your fixtures and potentially clog them.
Also, if you heat your water with electric, you won't want to get a tankless heater, they are inefficient and inconsistent with their hot water supply. In


Recommended: Report highlights poor water quality at nation's beaches

29.06.11 | msnbc.com

Before you wade into the water this summer, you may want to consult the beach water report released Wednesday by the Natural Resources Defense Council.

The report found that the number of closing and health advisory days at America’s ocean, bay and Great Lakes beaches spiked to the second-highest level measured by the NRDC in the past two decades.

Using data gathered at more than 3,200 beaches nationwide, the nonprofit environmental group found that 70 percent of the 2010 beach closings and health advisories were issued after testing showed bacteria levels in the water exceeded health standards. Pollution sources include storm water runoff and sewage overflows. Overall, 8 percent of water samples exceeded national standards, a slight increase compared with 7 percent for the past four years.

Study Shows Water Wrinkles May Help The Hand Grip Better | Geekosystem

We all get them. The little wrinkles that turn our finger tips into raisins after time in a swimming pool or even just your daily shower. But why on Earth do we need “pruney” fingers? Evolutionary neurobiologist Mark Changizi from 2AI Labs in ID is challenging our common perceptions about the wrinkling of our finger tips. Contrary to popular belief that the changes in our fingers are caused by the absorption of water, Changizi believes the wet finger wrinkles may be a valuable adaptation that allows us to grip objects better under slippery conditions.

According to Changizi, the wrinkles may act like rain treads on tires, creating channels that allow water to drain away when our fingers are pressed against a wet surface. This would allow the fingertips to make more contact with the wet surface, thus having a better grip. But Changizi’s hypothesis is not without skeptics....

Water gushed from the pipe covering the street with up to two feet of water.  Local business owners scrambled to fill sandbags to keep the water from entering their stores. Still a handful of stores have some water damage.

“The water was going pretty fast. It didn’t want to stop,” said store owner Hector Olazab.  “It was raining pretty hard and it just came out of nowhere.”

City crews dug a hole to get to the broken section of pipe and are still pumping water out of the hole.  They will then repair the pipe, fill in the hole and repave the street.

They are estimating that the repairs will be complete by noon Wednesday.
