Typically, a tankless hot water heater uses about 30-50% less propane compared to a traditional tank-style heater. This is due to the fact that tankless hot water heaters only heat water when it is needed, whereas traditional tank-style heaters constantly maintain a large volume of hot water.
Another advantage of tankless hot water heaters is that they have a longer lifespan than traditional tank-style heaters. This means that the initial investment in a tankless hot water heater can pay off in the long run through reduced propane usage and maintenance costs.
