天然气是萨凡纳最常用的加热水的燃料，最好的即热式取暖器使用天然气. 有电加热器，但需要200安培的电源. Tankless water heaters heat your water as it flows through the device; they are compact and almost silent in their operation. A conventional water heater with a tank will eventually run out of hot water when the tank is empty; a tankless water heater can deliver a limitless supply of hot water instantly as long as water is flowing through it.
一个基本的无罐系统也可以减少大约15%到25%的天然气费用.
