Corrosion is often the silent enemy of water heaters, but this model comes equipped with an advanced corrosion protection system.

The unit offers a 10,000 BTU input with a recovery rate of 14.14 gallons per hour on LP gas, which is great for quickly heating water during those busy mornings or after a long day on the road. Additionally, the optional electric element expands power options, allowing for 6.10 gallons per hour recovery on electric and an impressive combined recovery rate of 20.24 gallons per hour when using both LP gas and electric element. This versatility means I can optimize hot water availability depending on my power sources and needs, a feature that makes this water heater truly adaptable and efficient.
