How Tankless Water Heaters Work. Â­It's the holiday season and your peaceful suburban domicile is overflowing with houseguests. You need a nice, hot shower to soothe your nerves, but you're in line behind your in-laws and cousins. In times like these, you'll be glad you installed that new tankless water heater in your garage.
