Gas vs. Electric Hot Water Systems
Shorter Life Span
Tankless gas hot water systems have a lifespan of up to 20 years whereas electric storage hot water systems will only last up to 10 - 12 years.
Greater Upfront Cost
Tankless gas hot water systems can cost up to 50% more than an electric hot water system depending on the size.
Larger Storage Needed
Electric storage hot water systems require a tank and a larger installation area whereas tankless gas hot water systems are much smaller and can be attached to a wall taking up much less space.
Cheaper Running Costs
Though gas hot water systems have a higher upfront cost, they are much cheaper to run than electric storage hot water systems. On average, after the first year, a gas hot water system will have already made up for the higher upfront cost.
Limited Supply of Hot Water
Tankless gas hot water systems heat water whenever it is needed whereas storage electric hot water systems heat a tank full of water. Once that water has been used up a new tank will need to be heated before you can use your hot water again.
