Tankless water heaters are growing in popularity. These high efficiency water heaters heat the water as it flows through the device, and do not retain any water internally, except for the water that is in the heat exchanger coil. The chief advantage of a tankless water heater is the continuous flow of hot water; as compared to a limited flow of continuously heating hot water from conventional tank gas heater.
Some advantages of a tankless water heater unit:
- Long-term energy savings
- Unlimited hot water
- Less physical space taken up in your home
- No risk of water damage
