The size of the tankless water heater you should upgrade to depends on several factors, including:
Hot water demand: The size of the tankless water heater must be able to meet the hot water demand of your home. This includes the number of people living in the home, the number of hot water fixtures, and the hot water usage patterns.

7.0 GPM (Gallons Per Minute) - Rated for 4-5 applications means enjoying on-demand hot showers for up to 3 bathrooms simultaneously
Climate: The size of the tankless water heater will also depend on the climate in your area. Colder climates require larger units to provide a constant supply of hot water.
Gas line capacity: The capacity of your gas line will also play a role in determining the size of the tankless water heater. If the gas line is not large enough to support a larger tankless water heater, you may need to upgrade the gas line before installation.
Energy efficiency: Consider the energy efficiency rating of the tankless water heater. A more efficient unit may be smaller in size but still able to meet your hot water demand.
It is recommended to consult a licensed plumber or HVAC professional to determine the appropriate size tankless water heater for your home. They can assess your hot water demand and other factors to help you make an informed decision.
