18 July

When no repair and professional plumber is enough to fix your hot water system or heat pump, well, it must have been many years already for your old system and nothing lasts forever, so let’s take a closer look at and shop for a replacement. Let’s see which is the perfect new water heater for you at a good price. Maybe, gas hot water heater or gas continuous flow systems? Or electric water heaters from the many choices available in electric models.

You can try cost-effective new models or stick to your old and tested brand. But you need to consider your budget. A hot water system is a significant investment, but you could save some back on your bill rather than maintain a faulty one or buy a low-quality one.

You must also think about how much hot water you need, whether to have a water tank or go tankless. Take into account also your water usage, property and household size. And consider how energy efficient you want to be, think about greenhouse gas emissions. For every model and type, there are advantages and disadvantages. So, without further ado, let’s see the pros and cons of gas or electric hot water system. Are gas systems better for you? Or should you consider electric hot water heaters?

For most households, the running costs of heating water or heat pumps accounts for a quarter or more of the entire energy bill, not considering yet gas heaters and electric system or any other type of hot water heaters like continuous flow hot water or instant hot water and solar hot water systems. Also, installation costs shouldn’t be set aside for this will also create a dent in one’s budget. It means the gas vs electric hot water question is one you need to get right.

Both gas hot water systems and electric hot water system types of hot water systems are available as hot water cylinder or storage units or storage tank, where heated water is stored in an insulated tank or instantaneous ‘tankless’ systems, and water is heated on demand.

Let’s get the lowdown on gas vs electric hot water system with the important things to know about each and give you a more informed decision.

Gas Hot Water System vs. Electric Hot Water System

1. Efficiency

Regarding efficiency, look at their respective energy factors (EF). The higher efficiency heaters will have higher EF numbers. This number evaluates how effective a water heater is at producing hot water. It also measures how much fuel or electricity is required to heat your water.

Electric hot water system wins out from an efficiency perspective with an EF that can go higher than 0.9 compared to conventional gas hot water systems.

Most of the energy loss from gas hot water systems are during the venting process, which doesn’t occur in an electric hot water heater.

But with climate change now on everyone’s lips, households and governments are trying to spruik more efficient alternatives.

2. Installation

With an up-front price and because they’re easy to install or replace, electric hot water is still a prevalent choice.

Gas hot water systems models cost more upfront and are more costly in maintenance and installation.

Gas hot water systems need a more complicated installation that includes a ventilation system. If you’re switching to a gas water heater, PVC pipes will be required to vent through the roof. With no exhaust gas, they can be very compact. You will also need to perform regular maintenance and repair for this ventilation system when the gas system water heater is replaced.

3. Operating Costs

Despite the higher upfront cost, most gas water heaters make up for this price difference within a year, so long as they are well maintained. And your energy bills will likely be lower with a gas water heater.

You’ll likely spend less money overall if heating your water supply with gas. Natural gas is one of the cheapest sources of energy, and in most cases, the cost of electricity will be much higher.

But technology is speeding ahead to make electric hot water options that involve off-peak rates to heat water overnight, which is less costly.

4. Safety

Like any other appliance run on gas, water heaters are susceptible to gas leaks if they run on propane or natural gas. This can be a health hazard and poses a danger to your property and safety.

Although with proper maintenance and periodic inspections, you can lessen the threat with your gas water heater. But you’ll never experience this with your electric hot water system. And electrical safety issues are less than the high risk of gas leaks.

5. Lifespan

A continuous flow gas-powered hot water system has an average lifespan of 15-20 years with proper care. Electric hot water systems can last at least 8- 12 years, depending on whether it is a tank system or tankless.

How you take care of your hot water system also weighs on its lifespan. If you maintain it well and promptly respond to issues, you can double the lifespan of your hot water system, be it gas or electric.
