Enter the water-heater address.
We’ll check whether the location is inside the saved air-quality boundary.
Why the address changes the equipment
Is this address inside Utah’s low-NOx boundary?
Check the location first. Utah’s emissions rule covers natural-gas heaters in mapped air-quality areas. It does not cover electric or propane heaters. The boundary does not simply follow city or ZIP lines.

Check the model before comparing prices
Two 50-gallon tanks can have different burners. For a natural-gas heater inside the boundary, check the exact model’s emissions label against the limit for its burner size and use. The map cannot check the heater for you.
What about the heater I already own?
Being inside the map does not mean a working heater must come out. This rule concerns sales and installations. Older equipment and some special uses have exceptions; check those before choosing a replacement.
What Ultra-Low NOx means
NOx means nitrogen oxides, gases that form when fuel burns and contribute to air pollution. Ultra-Low NOx describes a burner designed to keep those emissions low.
