7 Essential Tips For Choosing The Right Water Heater For Your Home

How to choose a water heater

Choosing the best water heater for your home is crucial for comfort and energy efficiency. To make an informed decision for how to choose a water heater?, prioritize what matters most to you. 

In this article, we will discuss seven essential tips to help you select the right water heater, whether you’re upgrading an old electric one or installing a new solar water heater. These tips will empower you to choose wisely.

1. Think about Your Hot Water Needs

Understanding your household’s hot water needs is the first step in choosing the right water heater. Different household sizes and water usage patterns require different water heaters.

For instance, a family of four will have different needs compared to a single individual. On average, a person uses about 64 gallons of water per day, with 17 gallons dedicated to showering alone. Following are different types of water heaters.

  • Tankless Water Heaters: Ideal for households with varying water usage patterns as they heat water on demand.
  • Storage Water Heaters: Suitable for homes with consistent, high water usage as they store hot water in a tank.
  • Heat Pump Water Heaters: Efficient for areas with moderate to warm climates.
  • Solar Water Heaters: Best for sunny regions with high solar potential.

Knowing your household’s hot water needs is crucial for choosing the right water heater tankless, storage, heat pump, or solar. Each customized to varying usage and climates.

2. Consider Energy Efficiency

In choosing a water heater, energy efficiency is crucial for reducing both your energy bills and your carbon footprint.

  • Energy Star Ratings Look for Energy Star-rated water heaters. These units meet strict efficiency standards set by the U.S. Environmental Protection Agency and can save you up to 14% on water heating bills.
  • Annual Operating Costs Tankless water heaters typically cost less to operate annually compared to traditional storage heaters. For example, a tankless unit might cost around 367 – 440 AED per year, whereas a storage unit could cost 734 – 1,101 AED.
  • Government Incentives and Rebates Many governments offer rebates and incentives for purchasing energy-efficient appliances. Check local and federal programs to potentially save on your initial investment.

Consider energy efficiency to save on costs and lessen environmental impact, taking advantage of Energy Star ratings and government incentives for maximum savings.

3. Check Fuel Sources 

The availability and cost of different fuel sources can influence your decision. Widely available, but can be more expensive in areas with high electricity rates. 

  • Natural Gas: Often cheaper than electricity, but requires a gas line connection. 
  • Propane: Good for rural areas without natural gas, but generally more costly. 
  • Solar: Environmentally friendly and cost-effective in sunny regions.
  •  Hybrid: Combines electricity and other sources for increased efficiency.

Research local fuel prices and availability. Natural gas might be a cost-effective choice in urban areas, while propane or electric might be more practical in rural locations.

4. Decide The Right Size And Capacity

Choosing the correct size ensures that your water heater meets your household’s demand without wasting energy.

  • Understanding Gallon Capacity (for Tank Heaters): choosing a storage water heater, the tank size is important. Smaller households can use a medium-sized tank, but larger families might need a bigger tank to have enough hot water available.
  • Flow Rate (for Tankless Heaters) Calculate the required flow rate (in gallons per minute) based on simultaneous water use. For instance, a showerhead uses 2.5 gallons per minute, so a tankless heater with a 5 GPM flow rate can handle two showers at once.
  • First Hour Rating (FHR) The FHR indicates how much hot water the heater can supply in an hour. For a family of four, look for an FHR of at least 50 gallons.

Choose the right water heater size for your home’s hot water needs, whether it’s a storage tank or tankless, by considering tank size, flow rate, and First Hour Rating (FHR).

5. Durability And Warranty 

Understanding the expected lifespan and warranty of different water heaters can help you make a cost-effective choice.

  • Tankless Water Heaters: 15-20 years 
  • Storage Water Heaters: 8-12 years 
  • Heat Pump Water Heaters: 13-15 years 
  • Solar Water Heaters: 20 years

Look for warranties that cover both parts and labor. A good warranty typically lasts 6-12 years for storage heaters and 10-15 years for tankless models.

6. Quality Of The Tank And Heating Element

Choosing a water heater with a high-quality tank and heating element is crucial for long-term efficiency and reliability. The tank’s material, such as stainless steel, glass-lined steel, or polymer, determines its durability and resistance to rust, making it ideal for areas with hard water. 

Stainless steel tanks offer robust durability, while glass-lined tanks retain heat effectively and protect against rust. Equally important is the quality of the heating element, which significantly impacts the heater’s efficiency and energy consumption. 

Opting for a Rust-proof water heater ensures optimal performance, preventing scale deposits from hard water and extending the appliance’s lifespan.

7. Installation And Maintenance Requirements

Proper installation and regular maintenance are key to the longevity and efficiency of your water heater.

  • Professional Installation Hire a professional for installation to ensure safety and optimal performance. Improper installation can lead to inefficiency and hazards.
  • Maintenance Needs Regular maintenance tasks include flushing the tank to remove sediment, checking the anode rod, and inspecting the pressure relief valve. These steps can prevent costly repairs and extend the unit’s lifespan.
  • Cost of Installation and Maintenance Installation costs vary but typically range from 1,835 to 5,505 AED. Maintenance costs are minimal, often around AED 367 annually, but can prevent expensive repairs down the line.

Installing and maintaining your water heater properly is key for it to work well, last long, and stay safe, which helps avoid costly repairs.

What Is The Most Efficient Type Of Water Heater?

The most efficient type of water heater is a heat pump water heater. It uses electricity to move heat from one place to another instead of generating heat directly, making it 200-300% efficient. Some models place the compressor unit outside to reduce indoor heat loss.

How Do I Calculate What Size Water Heater I Need?

To find the right size water heater, multiply the number of people in your home by 12 gallons to determine the First Hour Rating (FHR). For instance, a household with 4 people needs an FHR of 48 gallons.

How Much Should I Spend On A Water Heater?

The cost of a water heater varies by type and size. Standard tank heaters typically cost  1,835 – 5,505 AED, while more efficient models like heat pumps or tankless heaters range from 3,670 – 11,010 AED or more. Consider both the initial cost and long-term energy savings.

How Can I Save Money On Hot Water Heat?

To save money on hot water heating, lower your water heater thermostat to 120°F (49°C), insulate the heater and pipes, and install low-flow fixtures. Upgrade to an energy-efficient water heater like a heat pump or tankless model.
