Therefore, this water heater type is suitable if you intend to use an extended pipe or need flexibility during installation.
Direct venting becomes and types highly recommended to homes if you don’t depend on electricity. They work by draining flue gases with the pressure difference between the external colder air and flue air. There’s no need to panic about possible leaks because these systems utilize external combustion air. Besides, their pipes and combustion chamber are completely sealed.
Additionally, these units are associated with a quiet operation because they don’t have movable parts. On top of that, you will not keep watching the system because they need minimal maintenance. With these heaters, there are minimal chances of your house being subjected to negative pressures.
The pipe in the pipe kind gives you a chance to terminate the vent at a specific point. For this reason, the negative becomes the distance limitation.

Its source of fresh air is outside to enhance combustion while eliminating used gases via the fan. Based on your concern on where to situate water heaters, regulations guide when to install a vent.
