Suburban SW16DEL 16-Gallon Gas+Electric RV Water Heater
Suburban SW16DEL 16-Gallon Gas+Electric RV Water Heater Review
The Suburban SW16DEL is a 16-gallon dual-energy RV water heater — the largest RV water heater in Suburban's lineup. Sized for very large Class A motorhomes and luxury fifth wheels.
Specs: 16 gallons stored, 12,000 BTU propane burner, 1500W electric element, recovery ~17 gph propane or 6 gph electric. Porcelain-lined steel tank with magnesium anode rod.
The 16-gallon capacity is uncommon — exceeds typical RV demand even for 6-person families. Found in very large luxury motorhomes (over 40 ft) and high-end fifth wheels with multiple bathrooms.
About $750 unit, $400-$600 installed. Direct replacement for existing 16-gallon Suburban units in luxury RV applications. Service parts through Camping World.
- No combustion, no venting required — installs anywhere with 240V electrical access
- Below-average UEF 0.62 — modern standard models reach 0.65+, condensing 0.95+
- 2-year warranty — well below the 8–12 year category average; extended warranty advisable
- Resistance electric has slower recovery than gas at comparable capacity — schedule heavy use to match tank recovery
- Small 16-gallon reserve — supplemental or 1–2 person use only
