Why I Chose a Tankless Water Heater for My RV
I was tired of running out of hot water during trips and dealing with bulky water tanks. Tankless water heaters, like the Girard model, provide hot water on demand without storing it, which saves space and energy—perfect for an RV setup. The compact design was a huge plus for me.
Key Features I Looked For
