Electric tankless heaters may not be able to heat as much volume of water as a gas-powered heater will, but they can continuously provide hot water for you and your family. Also, they are relatively cheaper and easier to install than gas tankless water heaters.

Things to consider before choosing between gas or electric tankless water heater

Type of power available

This is like the most fundamental factor to consider before you go ahead to buy any tankless water heater. Consider the availability of electricity, propane gas, or natural gas; if you only have access to electricity, then you know you have to buy an electric heater, and if you only have access to propane gas or natural gas, then you have to get a gas-powered heater. It may happen in some cases that you have access to both power options when this happens; you have to consider some other factors like the price of both power options before making your choice.

Initial cost

This has to do with what you can afford to spend a tankless water heater initially. Typically, it costs far more to buy a gas tankless water heater than to buy an electric tankless water heater. If you bought an average electric heater, you would spend around $500, while you would pay double of that or more if you go for a gas heater. You have to be careful; however, because different costs come with buying and using tankless heaters; the other expenses such as installation cost and running cost.


There are a couple of things you should consider as regards installation before you go out to get either a tankless gas heater or an electric one. One of the things is the kind of apartment you live in; if you live in a house you built by yourself, or in one that you own, you may find it easier to install, however, if you live in a rented house, you will need the owner’s approval before you can install anything of such. Gas tankless water heaters are more expensive to install, and they can take more space because you’ll have to think about ventilation and other things. On the other hand, electric tankless heaters are cheaper, smaller, and their design makes them easier to install.

Running cost

This is one of the more tricky factors that you have to consider carefully. Generally, the price of gas is lower when it is compared to that of electricity, and when you look at this, you may feel it will cost less to operate a gas tankless water heater, this is true. However, you have to consider some other things that relate to maintaining your tankless water heating system. Under normal circumstances, gas tankless water heaters require regular inspection to ensure safety. Maintaining an electric tankless heater is cheaper, and even if something gets damaged in this system, it is easier to fix.

Impact on the environment

In this age, people are being advised to do more things with consideration for the environment. Thus, you should try to consider the impact of each option on the environment. Greenhouse gas emissions are harming the environment, and the burning of fossil fuels like natural gas and propane gas contributes significantly to this. Switching from the traditional water heater to the tankless system is more environmentally friendly, but there are other things you can also consider to contribute to environmental safety. Electric tankless water heaters are more environmentally friendly, especially if the electricity is generated from sources that do not increase greenhouse emissions.


While tankless water heaters are more functional and more sustainable than traditional water heaters, they are both durable, depending on how well they are maintained and how well they are installed. They are generally made with rust-resistant and non-corrosive materials, but when it comes to maintenance, it may be easier and cheaper to maintain an electric tankless water heater than a gas-powered one. With adequate maintenance, though it may cost more, a gas tankless heater should last longer than an electric one.

Water supply and flow rate

This factor really has to do with the size of your family or the number of people that the tankless water heater will serve. If you have a large family, it might be better for you to install a gas tankless water heater; they can provide between 8-10 gallons of water per minute. If your family is a small one, or if the number of people that the water heater will serve is low, then the electric tankless water heater can serve you well; it supplies about 5 gallons of water per minute. You should know that climate can affect the flow rate; in colder weather, the flow rate can be lower than it will be in warmer climates.

Which one should you choose?

Ultimately, the decision depends totally on you. Some of the factors that have been discussed above should help you out in making your decision. What you should know is that choosing between a gas tankless water heater and an electric one is not a matter of just choosing which one you like best, it has to do with what you need.

Gas tankless water heaters are the more efficient type, and they are greatly recommended, but if you have just a small family or if you cannot afford a gas-powered heater, you should go for the electric tankless water heater. Plus, they are more environmentally friendly.
