Buying Guide: Best Gas Water Heater
When it comes time to replace your old water heater, one of the biggest decisions you’ll need to make is whether to go with a gas or electric model. Gas water heaters remain a popular choice for many homeowners due to their fast heating time, energy efficiency, and reliability. If you have access to natural gas in your home, a gas water heater is an option worth considering. This buying guide will walk you through everything you need to know to choose the best gas water heater for your needs.
How Gas Water Heaters Work
Gas water heaters heat water using natural gas or propane. The gas is burned, and the resulting hot gases heat a storage tank filled with water. The main components are the gas valve and burner, which control the gas input, and the flue, which ventilates gases out through the roof. The tank, which is coated with a glass lining, retains heated water until you need it. When you turn on a hot water tap, cold water enters the tank, pushing the heated water out through the hot water outlet.
Compared to electric models, gas heaters heat water more rapidly. The instant heat from the burning gas means you’ll never run out of hot water. Gas models also tend to have lower operating costs. They have higher energy efficiency, using around 60–67% of their input energy to heat water, compared to 90–97% efficiency for electric tankless models.
Key Factors to Consider
Fuel Type
Most gas water heaters run on natural gas, but propane models are also available. Natural gas tends to be more economical. Check on the availability and cost in your area. Homes not connected to utility gas lines can install an outdoor propane tank.
Energy Efficiency
Look for the Energy Factor (EF), which measures how efficiently the heater uses its fuel input. The higher the EF, the more hot water you get per unit of fuel. EF for gas models ranges from 0.5 to 0.7. Higher-efficiency units have better insulation and heat exchangers.
Tank Capacity
Check the tank size (measured in gallons) relative to your household size. Gas heaters range from 20 to 100 gallons. Larger families need bigger tanks. You also want an adequate first-hour rating (FHR), which is how much hot water is produced per hour.
Safety Features
Gas water heaters should have an automatic gas shut-off device that stops the gas flow if the pilot light goes out. Flammable vapor sensors will also shut off operations if they detect gas leaks. Look for units certified by CSA International.
Costs
The initial purchase price, energy costs, and maintenance costs are all factors. More efficient models tend to have higher upfront costs but save on fuel costs long-term. Also, consider the warranty period.
Size and Installation
Pay attention to the dimensions, weight, venting requirements, and clearance space needed. Proper installation is important for safe operation, so hire a professional if needed.
Conclusion
Choosing a suitable gas water heater requires balancing factors like fuel type, tank capacity, efficiency rating, and overall costs. Determine your household’s hot water requirements, fuel availability, and budget. Do some comparison shopping while keeping an eye on brand reputation and product certifications. With some careful research, you can find an optimal gas water heater that will provide reliable hot water for your home. Installation is best left to professionals to ensure safe and proper operation. With the right gas water heater, your family can enjoy an endless supply of hot water for years to come.
Frequently Asked Question
What size gas water heater do I need for my home?
The size of the gas water heater you need depends on factors like the size of your household, your hot water usage patterns, and the climate where you live. As a general guideline, a family of four typically requires a 40–50 gallon capacity heater, while larger households may need a 50–80 gallon unit. Consulting with a plumbing professional can help determine the ideal size for your specific needs.
How long does a gas water heater typically last?
Gas water heaters usually have a lifespan of around 8 to 12 years with proper maintenance. Regular flushing to remove sediment buildup, inspecting and replacing sacrificial anode rods, and ensuring proper ventilation can help extend the life of your unit. However, factors such as water quality and usage patterns can also influence longevity.
Are gas water heaters energy-efficient?
Gas water heaters can be energy-efficient compared to electric models, especially in areas where natural gas is readily available and relatively inexpensive. Modern gas water heaters often feature energy-saving technologies such as improved insulation and electronic ignition systems. Look for models with a high Energy Factor (EF) rating to ensure efficient operation and lower utility bills.
What maintenance tasks are necessary for a gas water heater?
Regular maintenance is essential to keep your gas water heater functioning optimally. Tasks include flushing the tank annually to remove sediment, checking and replacing the anode rod every 2-3 years, inspecting the burner and flue for debris or corrosion, and testing the pressure relief valve for proper operation. Following the manufacturer’s maintenance recommendations outlined in the owner’s manual is crucial.
How do I know if my gas water heater needs repair or replacement?
Signs that your gas water heater may need repair or replacement include inadequate hot water, strange noises like rumbling or banging, visible leaks or corrosion on the tank, fluctuating water temperatures, and an age approaching the end of its expected lifespan. If you notice any of these issues, it’s advisable to contact a qualified plumber to assess the situation and recommend the appropriate course of action, which may involve repairs or installing a new unit.
