The gas vs electric hot water debate has been going on for many years and will continue long into the future in all likelihood. Some times the focus is on the greener choice, sometimes it is about the cost, and there are other considerations people make depending on personal needs. Here is a look at some of the things to think about when you are choosing a gas or electric hot water system for your home.
What are the cost differences?
So if you just look at the bills each month, gas is cheaper in terms of running cost. While the installation of a gas hot water system costs more than installing an electric system, based on the savings you’ll make you can typically get that extra money back in a year or two of use. So then after that time is up your savings kick in.
Installation costs are another factor in the cost differences between an electric hot water system vs gas. An electric hot water system costs less to install and is a simple process to connect it to the power supply. With a gas system, you pay more for the installation and you have to use a licensed gas plumber who has the proper certification to do this and connect it to the gas pipes and make sure the venting is right and so on. It takes longer, needs specialised people and so costs more.
Do you have a gas or electric hot water system now? Hot water system replacement costs will be higher if you’re switching from electric to gas or vice versa since new wiring and gas pipes need to be installed to supply the unit.
How long will you live there for?
How long you are going to live in that home is a key part of your decision between an electric hot water system vs gas. If you are going to be there for 5 years or longer you can consider choosing a gas installation as you will be there for long enough to get your money back and then enjoy the big savings. If you are planning on moving in the next couple of years then you might make a different choice that has short term benefits.
When talking about costs, it’s important to note that any repairs can dint your savings. So ask about any maintenance needed after the installation to avoid hot water problems.
Tank or tankless?
A closer look at the tank or tankless questions with gas vs electric hot water systems shows that this has a big impact on how much energy a unit uses. With systems that use a tank, they store the heated water so that it is there when the homeowner needs it. There are different tank sizes but that average one for a regular home begins at 250 litres and then as the home gets bigger so does the tank. Tank models though are less energy-efficient than tankless models.
If your big drive to getting a new system is to be more energy-efficient and go green, tankless is for you. However, they are best suited to smaller homes and apartments. Tankless units are more efficient because it is not using energy to heat up a large tank and then keep that tank hot all the time. It generates hot water on demand. It is worth noting here that if green energy is very important to you, solar is also an option!

Gas VS Electric Hot Water System: Conclusion
When deciding whether to have a gas or electric hot water system if you are staying there for a few years, gas makes sense. You save money on your energy bills and will get back the extra installation and system costs. If you are not planning on hanging around then electric makes more sense, especially if you are replacing an electric hot water system. With both gas and electric, tankless is more energy-efficient and so also saves money, however it is not the best option for large buildings.
