What Are The Different Types of Tankless Water Heaters?
Electric
If you decide to stick with an electric tankless water heater, analyze the amperage, voltage, and circuit breaker requirements carefully before buying.
Most of the devices will vary from 110V to 277V; each model has different requirements. So make sure that your house electricity system can manage the water heater you're going for.

Inspect your gas line to ensure it will satisfy the requirements of your brand-new gas-fired tankless water heater.
How to Choose A Water Heater With The Right Flow Rate?
It's important that you choose a water heater with a flow rate that aligns well with the taps in your home. Each product has its own temperature limit and flow rate. If the water doesn't get hot enough, or if the flow rate is too low or too high, the heater won't do the job properly.
For example, a shower might have a demand of 4 gallons per minute while a dishwasher may only demand 1.5 gallons per minute at 100 degrees.
