So a tankless water heater heater will still cost less to run.
Tankless coil vs electric water heater.
Tankless systems are typically electric oil or gas fired.
Even though a hybrid heat pump is technically more energy efficient gas is generally cheaper than electricity in the phoenix area.
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.
Sometimes called on demand water heaters tankless systems supply continuous hot water when needed and for this reason have increased energy efficiency.
Can be used in any climate and the fuel sunshine is free and a renewable resource.
True the advantages of gas tankless heaters are fewer in number.
50 more efficient than gas electric water heaters.
When compared with typical electric storage tank models propane tankless systems save more than 150 in annual energy costs.
By contrast a tankless water heater is basically a box around a heating coil.
Well that choice depends on the type of energy source you have available.
It has to run pretty much constantly in order to keep the tankful of water hot for when you want it.
These water heating systems work with forced air systems and hydronic or radiant floor heating.
A quick glance at the electric vs propane tankless water heater chart may give you the impression that electric is the better option.
Indirect systems can be fired by gas oil propane electric solar energy or a combination of any of these.
Gas and electric tankless water heaters run more efficiently than the conventional water heaters of the same fuel type.
May require a backup system for cloudy days or high demand times.
Tankless systems heat your water on demand using gas or electric coils.
A tankless coil water heater provides hot water on demand without a tank.
Gas heaters can have a higher capacity.

Although tankless water heaters heat water on demand they do have output limits on their flow rate.
In actual fact it is a bit more complex.
However for some people they can far outweigh the disadvantages.
