Rheem Mobile-Home Specific 30-Gallon Gas Water Heater
Rheem Mobile-Home Specific 30-Gallon Gas Water Heater Review
The Rheem Mobile-Home Specific 30-Gallon Gas Water Heater is engineered specifically for mobile home and manufactured housing applications. Mobile homes have specific HUD code requirements for water heaters: side-wall venting where applicable, specific dimensions, and certified materials.
Specs: 30 gallons stored, 32,000 BTU input, UEF 0.58, 60-gallon FHR, 6-year tank warranty. Atmospheric vent through B-vent. Direct-spark ignition. Magnesium anode rod. Approximately 50" tall × 18" diameter — fits standard MH water heater compartment dimensions.
The 30-gallon capacity is the standard mobile home size. Most MH water heater cutouts are sized for 30-gallon units; upsizing requires modification.
About $499 unit, $1,100 installed. Right buyer: mobile home owner replacing existing MH gas water heater. The MH-specific certification is what differentiates this from equivalent residential Rheem Performance 30-gal Gas.
- Natural gas combustion — faster recovery than electric resistance at comparable tank size
- Below-average UEF 0.61 — modern standard models reach 0.65+, condensing 0.95+
- 6-year warranty — below the 8–12 year average for premium models in this class
- Small 30-gallon reserve — supplemental or 1–2 person use only
- Low 30000 BTU input — slower recovery than modern 40K+ BTU alternatives
