For example, If you want to be running the kitchen tap with a flow rate of 1 GPM (gallon per minute) plus the shower with a flow rate of 2 GPM. You should buy a heater with the capacity to handle more than 3 GPM.
Can tankless keep up with demand?

This is more than enough for most consumers. However, if your needs are higher, you can choose a big heater that is able to heat up even 7.5 GPM.
Tankless condensing vs non-condensing?
Condensing are those heaters that heat water using a gas burner, and instead of venting gases, the exhaust gases are condensed and reused to generate more heat. They are more efficient and energy saving. On the other hand, non-condensing heater vent the exhaust gases outside. While condensing water heaters are efficient they are more complicated and prone to malfunction.
How long does tankless water heater last?
Tankless water heaters have a life expectancy of up to 20 years. On the other hand, tanked water heaters have a life expectancy of 10-15 years. Also, because they have parts which are replaceable, this can extend the life to many more years.
