Eccotemp L10 Tankless Water Heater

On Backorder until 31st May 2023


The Eccotemp L10 Tankless Heater is among hottest ;) propane tankless water heaters currently available.

It provides limitless heated water in your summer cottage, cabin, lake house, camper, RV, horse washing stall, potting shed, or wherever else you'll be needing hot water.

Two "D" cell batteries power the igniter only while water is running....No chance of overheating. It is perfect for use off-grid or in areas where there is limited or no electrical service.

At a flow rate of 2.65 GPM (full capacity), the L10 provides a 30°F to 35°F water temperature increase. At a flow rate of 2 GPM, the L10 gives approximately 50°F temperature rise. Decreasing the water flow further provides a further increase in the water temperature.

The Eccotemp L10 has standard water connections, which makes plumbing with standard fixtures quick and easy. The unit also works flawlessly on modified water systems like a 12-volt pump.

The unit needs a 2" clearance from the wall, 12" side to side away from any flammable object, 36" from a window or overhang, and 18" up from the ground.
