Gas Tankless Water Heater Pros
1. High Performance
If we talk about performance then nothing can beat gas tankless water heater. Electric tankless water heater can’t even stand in front of gas one in terms of performance.
Most of the gas tankless water heater provides hot water supply heater with the flow rate of at least 8GPM and their flow rate increase upto 11 GPM. It is enough to meet the requirements of large homes.
So if you need more hot water then gas tankless water heaters are perfect. That’s why customers who have bigger households prefer a gas tankless water heater. And if you are living in a colder climate then they are the best option for you.
2. Operating Cost Decrease Gradually

So the overall cost of a gas tankless water heater is quite low as compared to the electric one.
Gas Tankless Water Heater Cons
1. Gas Tankless Water Heaters are Quite Expensive
The purchasing cost of a gas tankless water heater is much more higher than the electric one.
Although non-condensing systems are cheaper but if we have a look on their efficiency then its quite low. Non-condensing gas water heaters don’t collect the water vapors.
They send them out through a flue on the other hand condensing gas water heaters uses the vapors and reduce wastage of energy. Hence, the non-condensing gas water heaters may be cheap but the result is not satisfactory.
2. The Installation Process is Complex and a Bit Expensive

You are always at risk of poisonous carbon monoxide gas that can explode your home.
4. Annual Maintenance is Required
If you wanted to minimize the risk that a gas tankless water heater poses then you are required to call the HVAC professional for inspecting the safety on an annual basis.
Other than this you are supposed to flush your gas tankless water heater at least once in a year this will increase the life span of your heats.

And for other maintenance, you just need to clear the inlet screen filter to avoid any kind of obstruction.
5. High Thermal Efficiency and Easy to Repair
When we talk about thermal efficiency then no water heater can stand in front of an electric tankless water heater.
Some electric tankless water heaters are upto 99% thermal efficient. If we talk about gas tankless water heater then they are only 85% thermal efficient (Maximum).
On the other hand, if we talk about bug fixing then electric tankless water heaters are also easy to repair and in case of tankless gas water heater, troubleshooting is another thing, its even difficult to identify the bug.
This is again the advantage of an electric tankless water heater over gas one.
Electric Tankless Water Heater Cons
1. The Flow Rate of Hot Water Heater is Quite Low
The hot water heater flowrate of an electric tankless water heater is quite than a gas one. Its flowrate is upto 8 GPM (gallons per minute) in a warmer climate and upto 3.5 GPM in a colder climate.
So it will be unable to fulfill. the requirement of the big household located in the colder climate.
2. High Power Requirement
If you living in a colder area then your electric tankless water heater requires more electric power to operate. In colder areas, you will require 200 AMP electric supply and in warmer areas 150 AMP(maximum) electric supply is sufficient.
