Gas Vs Electric Heater Pros Cons

Gas vs Electric Hot Water Systems – Pros, Cons, Comparisons and Costs

A HWS, whether gas or electric, is an integral part of your home and an essential asset that many rarely think about until it comes to a halt. Given that the normal lifespan of a good water heater is between 8 to 15 years, it is only a matter of time before you will need to replace yours.

A standard hot water system features two types; gas and electric. Both have their pros and cons that you should consider before buying. Below is an outline of their differences to help you make an informed decision that will suit your home’s unique needs.

Gas vs Electric Hot Water System Costs

Gas hot water unit prices are much higher compared to those of electric units. Based on the flow rate and star rating, an electric HWS can be much less expensive than the gas system.

Unit Type & Size

System TypeAvg. Minimum PriceAvg. Maximum Price
Instant Electric$660$1400
Gas Storage$850 (135 L)$1700 (360 L)
Instant Gas$750$1800


Despite the gas hot water systems costing less to maintain due to the reduced cost of natural gas, the electric hot water system installation guarantees more efficiency. This is simply because of how the units function. A gas water unit must expel some of the used gas, which takes some heat with it in the process. On the other hand, an electric HWS uses almost all the energy received and converts it into hot water, ensuring less wastage.
