Tankless gas hot water heaters give you the flexibility to have multiple showers going, and then still have the water there after wards to run the dishwasher or the washing machine. The biggest factor in favor of a natural gas tankless water heater is their capacity. Several natural gas models are more compact than a regular tankless water heater, saving additional space.

Natural gas tankless hot water heaters come in several different models which can create between 2.5 to 6 gallons of hot water. Obviously, the larger capacity models are more expensive, but these are ideal for larger households where multiple hot water applications are needed at the same time. Natural gas tankless water heaters also provide consistent flow of hot water. Since gas water heaters require proper ventilation, you need to get the installation done by a professional.
