Electric Or Gas: Which Water Heater Type Should You Choose And Why?

Water heaters are an essential part of every home and office utilities. It takes care of heating the water without the need of boiling them manually.

There are two main types of water heaters: electric and gas. Two of them serve the same function - to heat water to a certain temperature.

But which one should you choose? Is one better than the other? What is/are the advantage/s of using one? In this article, we’ll help you answer those questions in order for you to choose the right one.

The Different Types

Electric Water Heater

An electric water heater is a device to heat water using, well, electricity. It is used to provide hot water for baths, showers, and other household needs.

Electric water heaters are usually more expensive than its gas counterpart but considered to be safer and easier to install. It also requires less maintenance than gas models.

One or more electric heating elements heat the water in the storage tank. The thermostat is used to control the temperature of the water in order to set it to the desired level.

Gas Water Heater

A gas water heater is a device that uses natural gas or propane to heat water for domestic use. It typically consists of a storage tank, a gas burner, and a thermostat.

The water in the storage tank is heated by a gas burner, which is ignited by a pilot light or electronic ignition system. The thermostat is used to control the temperature of the water, allowing you to set it to the desired level.

When you turn on the hot water tap, the hot water is drawn from the storage tank through the hot water line and into your plumbing fixtures.

Things To Consider

Electric Water Heater

Cost

The cost of having an electric water heater installed depends on the unit size, type, and any additional features or installation requirements. On average, you can expect to pay $800 to $1,500 for the unit and $500 to $1,000 for installation.

Efficiency

Electric water heaters are more efficient than older models that are powered by gas or oil. An electric water heater's efficiency can be determined by the size of the system, the produced water temperature, thermostat setting, and its energy factor of EF.

A higher EF means a more efficient water heater, most efficient models having an EF of 0.95 or higher. Overall, electric water heaters can be a very efficient way to heat water for your home, as long as they are properly maintained and used in an efficient manner.

Safety

Electric water heaters do not produce carbon emissions or other byproducts of combustion, which means they do not pose the same risk of carbon monoxide poisoning or other safety hazards as gas water heaters.

Environmental impact

If you are concerned about the environmental impact of your water heater, an electric water heater may be a better choice, as it does not produce carbon emissions.

However, it's important to note that the electricity used to power the water heater may have been generated using fossil fuels, which can contribute to climate change.

Gas Water Heater

Cost

Just like an electric water heater, the cost can also depend on the size, type, and additional features. But on average, the price can range up to $270 - $900 per 30 gallons, and the installation fee can go up $3000.

Efficiency

The efficiency of a gas water heater is typically measured by its energy factor (EF). A good gas water heating unit can give 0.6 to 0.7, which means they use about 60-70% of the energy they consume to produce hot water. And sometimes, a pretty efficient unit can give you an EF of 0.95 or even higher.

But like its electric counterpart, the efficiency would still depend on the model, size and year manufactured.

Speed

Gas water heaters can usually heat water faster than electric water heaters, which means you may have to wait less time for hot water when you turn on the tap.

Capacity

Gas water heaters are available in larger sizes than electric water heaters, which means they may be able to meet the hot water needs of larger households more easily.

Conclusion

There are pros and cons to both electric and gas water heaters, and the best choice for you will depend on your specific needs and circumstances. But is one really better than the other?

There are things you might consider such as fuel type and availability, initial cost, operating cost, and its environmental impact.

It is still up to you as a buyer and a customer on which to choose. Whether you choose this because of its efficiency that the other cannot offer.

The Best Air Conditioning Units for Homes in London, Ontario

By kevin Wu • May 20, 2025

As climate patterns shift and summers grow hotter across Canada, homeowners are increasingly turning to air conditioning as a necessary part of daily comfort. But with that comfort comes a cost—both financially and environmentally. If you're tired of soaring electricity bills or want to reduce your household's energy use, investing in the best energy-efficient air conditioners in Canada is a smart move. This guide is here to help you understand what makes an air conditioner energy-efficient, what types are most suitable for Canadian homes, and which models top the charts in 2025. We'll also look at common misconceptions and practical insights to help you make an informed decision without relying on guesswork—or risky DIY installations. Key Takeaways Energy-efficient AC units can significantly lower electricity costs and reduce your carbon footprint. In Canada, features like Energy Star certification and high SEER ratings matter most. Choosing the right AC isn’t just about the unit—it's also about correct installation and expert servicing. Carver Sheet Metal in London, Ontario offers expert advice and trusted installation services for the best air conditioning units Canada has to offer. What Makes an Air Conditioner Energy-Efficient? Understanding SEER and Energy Star Ratings When evaluating energy-efficient air conditioner , the Seasonal Energy Efficiency Ratio (SEER) is a crucial metric. This number indicates how much cooling a system delivers per unit of energy consumed. In Canada, a SEER rating of 14 or higher is generally considered efficient. Many of the best air conditioning units Canada homeowners trust have SEER ratings well above 18. Energy Star certification is another key indicator. These models meet government-backed standards for efficiency without sacrificing performance. According to Natural Resources Canada, switching to an Energy Star-certified AC can reduce cooling costs by up to 30% annually. Central vs. Ductless vs. Portable Units There’s no one-size-fits-all solution. Central air systems are ideal for larger homes, especially those with existing ductwork. Ductless mini-splits offer more flexibility and room-by-room control, making them perfect for renovations or homes without ducts. Portable units, while convenient, often lag in energy efficiency. If you’re in a city like London, Ontario, with its mix of older and newer homes, it’s critical to match the type of unit to your home’s structure and insulation level. That’s why professional consultation is key—something Carver Sheet Metal excels at. Why Energy Efficiency Matters More in Canada Our Unique Climate Demands Better Tech Canadian summers can swing from mild to sweltering, depending on the region. While a basic unit might suffice for coastal areas, inland cities like London, Ontario often face sharp temperature spikes. An energy-efficient air conditioner adapts better to these fluctuations while keeping consumption low. Furthermore, Canada's electricity prices vary by province, with Ontario typically ranking among the higher cost zones. Investing in a high-efficiency AC helps mitigate those long-term costs. Environmental Impact The environmental benefit of using an energy-efficient system cannot be overstated. Less power usage means fewer emissions. With Canada targeting net-zero emissions by 2050, every household can contribute by upgrading their cooling systems. Features to Look For in 2025 Smart Thermostat Compatibility More units now pair with smart thermostats, allowing better temperature control and scheduling. This minimizes energy waste and improves comfort. Variable-Speed Compressors Unlike traditional systems that switch on and off, variable-speed compressors adjust gradually. This reduces energy spikes and prolongs the unit’s lifespan. Quiet Operation & Compact Design Noise may not be the first thing that comes to mind, but it affects your living space significantly. Modern energy-efficient models are quieter and better suited for family or multi-use spaces. Top 5 Energy-Efficient Air Conditioners in Canada (2025) While we’re not naming specific brands to stay focused on your needs rather than promotion, here's what the top-rated units on the market share: SEER Ratings of 18–26 These are among the highest on the market and ideal for long-term savings. Energy Star Certified Every top pick meets or exceeds government standards. Wi-Fi Connectivity Control via smartphone apps for better energy management. Multi-Stage Cooling Offers customizable comfort while using less electricity. Trusted Warranty Longer coverage usually signals quality parts and engineering. Each of these features contributes to lower operational costs and a reduced carbon footprint—goals every homeowner in Canada should prioritize. Why DIY Isn’t the Answer for Installation Energy-efficient systems are only as good as their installation. A poorly installed AC unit, no matter how advanced, can leak air, short cycle, or draw too much power—completely offsetting any potential savings. In fact, government and utility providers recommend professional installation not just for efficiency but also for safety and warranty compliance.
