Hi Eric, thanks for writing in. This unit is meant mainly for plumbing and is not recommended for standalone use in radiant heating systems.
Hello, For a sulfuric smell, it is recommended that you install an aluminum anode rod, and for your model, it would be this one: https://www.supplyhouse.com/AO-Smith-100110627-3-4-Flexible-Plug-Anode-Rod-Aluminum
The clearance of 3 feet is not required but it is recommended by the manufacturer in case of the unit ever needing servicing. Having extra space can make it easier for a technician to work on it and get to certain spots and parts of the unit. Not having that clearance could make it quite difficult to service and thus create an issue.
Yes, it does include a temperature & pressure relief valve as well as a drain valve.
The decibel rating is roughly 55 on the high end.
The wattage of the lower element is 4500. The upper element is 4500 watts. The unit has the ability to use one element (upper or lower) at a given time for a maximum of 4500 watts total.
