Eccotemp L7 Outdoor Portable Tankless Water Heater

The Eccotemp L7 is a 1.9 GPM portable outdoor LP-fired tankless water heater, positioned between the smaller L5 (1.5 GPM) and larger L10 (2.6 GPM) in Eccotemp's portable line. Designed for moderate outdoor demand — primary cabin shower, RV exterior shower, small outdoor pool rinse.

Specs: 50,000 BTU propane burner, 1.9 GPM peak at a 35°F rise, battery-fired ignition (two D-cell batteries), single dial controls for combined gas and water flow. Outdoor mounting only — front-vented combustion makes indoor use unsafe.

The 1.9 GPM peak puts the L7 between handwash-only and serious shower capacity. At a 50°F rise (typical campground source water), throughput drops to about 1.4 GPM — a light shower but workable. The L7's appeal is portability: weighs about 8 lbs, hangs on a wall hook or tripod stand, packs in a duffle bag for camping trips.

Right buyer: regular outdoor camping trips, cabins with moderate use, RV exterior wash stations for medium-size rigs. Wrong buyer: indoor installation (always wrong), heavy multi-shower use (step up to L10 or EM-7.0), year-round outdoor exposure in freezing climates (drain and store seasonally).

About $290 unit, often bundled with showerhead and stand. 1-year warranty. Parts available through Eccotemp directly and major outdoor retailers.
