Tankless Water Heaters

Have you heard of Tankless Water Heaters?  They've been in use overseas for years and are becoming more common in the United States.

Though more expensive initially than tank type heaters, they are purported to function longer and use less energy, electric or gas.  No more idle water sitting in a tank being heated, waiting for someone to draw.  These heaters give instant heat (you control the temperature), are designed to be energy efficient, and will save you money in the long run.

This video describes just how they work and the advantages vs. a tank type water heater.
