Tankless water heaters only heat water when you need it, so minimal energy is wasted. That doesn't meant they're all the same, though.
Each product has ratings for the amount of heat it generates -- in British Thermal Units (BTUs) or kilowatts (kWs) -- and the actual volume of water delivered -- usually in gallons per minute (GPM).
Both of these factors must be considered to ensure you'll have enough hot water for your needs.
