Did you know that water heating accounts for about 18% of your home's energy use, making it the second-largest energy expense in most households?
That's a huge chunk of your utility bill tied to a single appliance!
Choosing the best water heater for your home isn’t just about keeping your showers hot—it’s also about saving money, improving energy efficiency, and ensuring your family’s comfort.
Whether you're replacing an old unit or installing one for the first time, Rosenberg Plumbing will walk you through everything you need to know to make a smart, informed decision.
Factors to Consider When Choosing a Water Heater
Capacity
The right water heater size makes a huge difference. Too small, and it'll struggle to meet your family’s demands. Too large, and you’ll face unnecessary energy expenses. This is where a water heater-size guide comes in handy.
Tank water heaters are typically sized by their gallon capacity, while tankless models are rated by their gallons-per-minute (GPM) output.
For example, a family of four might need a 50-gallon tank or a tankless system with at least 6-7 GPM.
Assess your household’s peak water usage to estimate the right capacity. Think about showers, dishwashing, and laundry that may occur simultaneously.
Fuel Source
Water heaters are powered by either electricity, gas, or, in some cases, solar energy. The fuel source you choose depends on your home's existing infrastructure, budget, and energy efficiency goals.
Consider the availability of gas lines or adequate electrical capacity when shopping. Knowing this upfront makes water heater installation smoother.
Understanding Energy Efficiency Ratings
No one wants skyrocketing utility bills, right? That’s why checking the energy efficiency ratings is just as important as water heater size.
Water heaters display the Uniform Energy Factor (UEF) score, which highlights their efficiency. The higher the UEF, the more energy-efficient the unit is.
Although energy-efficient models might cost more upfront, they often compensate with lower long-term operational costs.
For example, a high-efficiency electric water heater might use less power, while a gas-powered condensing model captures more heat, saving you money.
By understanding these ratings, you can find a balance that fits your eco-friendly goals and budget.
Gas vs. Electric Water Heaters
Gas Water Heaters
Gas water heaters are a popular choice due to their ability to deliver quick and consistent heating. They often suit the needs of larger households or those in areas with colder climates.
Pros
Faster Heating
Gas-powered models heat water significantly faster than their electric counterparts, ensuring a steady supply during peak usage times.
Reliable During Power Outages
Since they don’t rely on electricity, gas water heaters keep running even when the power is out—a big plus in areas prone to storms or blackouts.
Lower Operating Costs
If natural gas prices are affordable in your area, running a gas
water heater can be lighter on your wallet compared to electric ones.
Ideal for Large Families
With their quicker recovery rates, gas water heaters are excellent for larger households that require higher water volumes throughout the day.
Cons
Higher Upfront Costs
Gas models typically have a higher initial purchase price and installation cost, especially if additional ventilation work or gas line upgrades are needed.
Ventilation Requirements
Proper venting is essential to avoid carbon monoxide buildup, which can complicate water heater installation and sometimes increase expenses.
Safety Risks
Without proper maintenance, there’s a risk of gas leaks or carbon monoxide poisoning, making routine checks and servicing critical.
Electric Water Heaters
Electric water heaters are versatile and known for their straightforward operation and easier installation process. They’re a great fit for households with smaller water demands or where clean energy options like solar power are accessible.
Pros
Ease of Installation
Electric models are relatively simple to install since they don’t require venting systems or connection to gas lines. This reduces labor costs and installation complexity.
Efficient Heat Retention
Electric water heaters tend to have better insulation, meaning less heat loss and steady water temperatures over time.
No Risk of Gas Issues
With no combustion process involved, electric water heaters eliminate concerns about gas leaks or carbon monoxide exposure.
Quiet Operation
These units operate much quieter than gas water heaters because they don’t involve burner mechanisms. This makes them an excellent choice for homes where noise sensitivity is a factor.
Solar Compatibility
If your home uses solar panels, electric water heaters can seamlessly integrate, making them an eco-friendly and cost-efficient option.
Cons
Slower Heating Times
Electric models take longer to bring water to the desired temperature, which might not be ideal for larger families with high water demands.
Higher Operating Costs in Some Areas
If your home’s electricity rates are steep, operating an electric water heater could lead to higher energy bills compared to gas options.
Limited Efficiency in High-Demand Situations
While great for smaller households, electric water heaters can struggle to meet demands during heavy usage periods.
Decision-Making Flowchart
Determine Household Size
1-2 people? Opt for a smaller tank or a low GPM tankless unit.
3+ people? Look for larger capacities or higher GPM outputs.
Assess Energy Preference
Want lower long-term operating costs? --> Consider gas.
Need ease of installation and maintenance? --> Go electric.
Evaluate Your Budget
Tight budget upfront? --> Select a standard efficiency model.
Looking to save on future bills? --> Choose a high-efficiency UEF-rated unit.
