Well that choice depends on the type of energy source you have available.
Tankless coil vs electric water heater.
Indirect systems can be fired by gas oil propane electric solar energy or a combination of any of these.
By contrast a tankless water heater is basically a box around a heating coil.
So a tankless water heater heater will still cost less to run.
Even though a hybrid heat pump is technically more energy efficient gas is generally cheaper than electricity in the phoenix area.
May require a backup system for cloudy days or high demand times.
However for some people they can far outweigh the disadvantages.
Water is drawn from the top since heat rises and the heating coil works to raise the temperature of the whole tank when new water is added.

These water heating systems work with forced air systems and hydronic or radiant floor heating.
A tankless coil water heater provides hot water on demand without a tank.
Whereas traditional water heater installation costs around 500 tankless installation costs double or more.
It has to run pretty much constantly in order to keep the tankful of water hot for when you want it.
Gas heaters can have a higher capacity.
Sometimes called on demand water heaters tankless systems supply continuous hot water when needed and for this reason have increased energy efficiency.
We rated the annual energy consumption cost excellent for a gas.
In actual fact it is a bit more complex.
Can be used in any climate and the fuel sunshine is free and a renewable resource.
Although tankless water heaters heat water on demand they do have output limits on their flow rate.
Tankless systems are typically electric oil or gas fired.
Gas and electric tankless water heaters run more efficiently than the conventional water heaters of the same fuel type.
True the advantages of gas tankless heaters are fewer in number.
When compared with typical electric storage tank models propane tankless systems save more than 150 in annual energy costs.
50 more efficient than gas electric water heaters.
