A gas fired tankless natural draft hot water heater has a draft hood and uses no fan or blower but relies on gravity to expel the exhaust gas out of the house. It needs no electricity to operate. Even during power outage, user still can get endless hot water. Without moving part like fan or blower, it is more reliable. And it generally costs less than a forced draft water heaters. Our natural draft models with 10L and 12L capacity are most popular among our customers. Models ranging from 6L-7L-8L-10-12L are available, too. All models can be customized as per customer’s logo.
