Let’s have a detailed look on the pros and cons of both electric and gas tankless water heaters.


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

It’s no longer a secret that gas tankless water heaters are expensive than electric ones and their installation cost is also high.

But when we talk about monthly operating cost then we can say that the gas-electric tankless water heaters are very beneficial. It’s a monthly operating cost is very low and also decreases with time.
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 know that the purchasing cost of gas tankless water heater is very high but it’s the installation cost is way more higher.

You need to spend extra money on gas lines if they aren’t pre-installed at your house and it’s quite expensive.

And if you are living at high altitudes, then the installation process is way more problematic for you.

3. Complex Venting Procedure and High Risk

How could we forget the venting problem that came together with the installation of a gas tankless water heater?

If you are changing your gas tankless water heater with another model then you are required to change the venting as well as different models required different venting ducts.

And if we talk about the risk a gas tankless water heater poses then it’s no longer secret that how much damage it can cause if there is leakage in piping.

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.


Electric Tankless Water Heater Pros

1. Less Costly

The price of an electric tankless water heater is way lower than gas one.

So if you have low budget then the Electric tankless water heater is best option for you can easily find a high quality electric tankless water heater at a price starting from $500.

Even the top electric tankless water heater costs less than $1000.

3. Compact in Size

Although all tankless water heater are compact in size but electric tankless water heaters have an ultra-compact design.

Electric tankless water heaters are about 1/3 of the size of the gas tankless water heater. So if you are facing space problem then an electric tankless water heater is the best choice for you.

3. Maintenance is Less Expensive

Unlike gas tankless water heater the maintenance of an electric tankless water heater is minimal. You are required to flush it for long-lasting use only once in a year.

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.
