Simple questions

[Bart Ross]

So I am about to close on my first duplex. During my home inspection one of the water heaters showed it is 19 years old, the other is 2. So I know I am going to have to replace it in the near future. 

The question is this. When replacing a water heater has anyone ever used tankless water heaters vs the traditional tank water heater? What are the pros and cons in a rental unit?

Be extra careful with the sizing of the existing plant before you ever consider a conversion like this.

Tankless electric heaters need  high current circuits.

Tankless gas heaters need larger, higher load gas supply, chimney and venting systems.

The project will not be a simple plug and play.
