How to Select the Right Water Heater For Your Home

Water Heaters 101: How to Select the Right Water Heater For Your Home

A water heater is a household appliance designed to heat water for various domestic uses, such as bathing, cooking, cleaning, and more. It ensures a steady supply of hot water whenever you need it. The basic function of a water heater is to raise the temperature of cold water to a desired level for immediate use. There are different types of water heaters, but their primary purpose is to provide hot water efficiently. Choosing a water heater for your home involves considering several factors to ensure you select the right type and size of water heater that meets your household's hot water needs efficiently. 


To begin, determine your hot water needs by calculating your daily hot water usage in gallons. Consider activities like showering, dishwashing, laundry, and cooking, and the number of people living in your home. Remember that these calculations provide estimates and actual usage can vary based on personal habits, appliance efficiency, and other factors. It's a good idea to round up your calculated hot water usage to ensure you choose a water heater that can meet your needs comfortably. If you're uncertain about the calculations, consulting a plumbing professional can provide more accurate guidance based on your specific situation.


Types of Water Heaters

There are a few common types of water heaters to choose from:


  • Tank Water Heaters:  These are the most common type of water heaters. They consist of an insulated tank where water is heated and stored until it's needed. The heated water is drawn from the top of the tank when a hot water tap is turned on. They come in various sizes to accommodate different hot water demands.
  • Tankless Water Heaters: Also known as instantaneous or on-demand water heaters, these units heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water flows through a heat exchanger and is quickly heated to the desired temperature. They are more energy-efficient because they only heat water when it's needed.
  • Heat Pump Water Heaters: These use electricity to move heat from the air or ground to heat water. They are energy-efficient and work well in warmer climates but may have limitations in colder climates.
  • Solar Water Heaters: Solar water heaters use energy from the sun to heat water. They consist of solar collectors that capture sunlight and convert it into heat, which is then transferred to the water. These systems can be active (using pumps to circulate water) or passive (relying on natural convection).
  • Hybrid Water Heaters: A hybrid water heater, also referred to as a hybrid heat pump water heater, operates using a heat pump technology similar to what's used in air conditioners and refrigerators. The heat pump extracts heat from the surrounding air and transfers it to the water in the storage tank. It doesn't generate heat directly, but rather moves existing heat from one place to another. In addition to the heat pump, hybrid water heaters typically have an electric heating element that can be used as a backup when there's a high demand for hot water or when the ambient air temperature is too low for efficient heat pump operation.


Fuel Sources For Water Heaters

Water heaters can be powered by various fuel sources, depending on the type of heater and regional availability. The most common fuel sources for water heaters include:


  • Electricity:  Electric water heaters use electric heating elements to heat the water in the tank. They are widely used and are suitable for areas where electricity is readily available.
  • Natural Gas: Gas water heaters, also known as tank-type or tank-type gas water heaters, use natural gas as the fuel source to heat the water. They are commonly found in many households due to the availability of natural gas in certain areas.
  • Propane: Propane water heaters work similarly to natural gas water heaters but use propane gas as the fuel source. They are often used in areas where natural gas is not readily available.
  • Solar Energy: Solar water heaters use energy from the sun to heat water. They have solar collectors that capture sunlight and transfer the heat to the water.


Other Items to Consider When Selecting a Hot Water Heater

Size/Capacity: The size of the water heater is crucial to ensure you have enough hot water. Look for the First Hour Rating (FHR) or gallons-per-minute (GPM) rating, which indicates how much hot water the heater can provide in the first hour of use.


Energy Efficiency: Check the Energy Factor (EF) rating for efficiency. A higher EF indicates greater efficiency. Tankless and heat pump water heaters are generally more energy-efficient than traditional tank heaters.


Space and Installation: Consider the available space for installation. Tankless and smaller units might be more suitable for homes with limited space.


Upfront Cost and Long-Term Savings: Balance the initial cost with potential long-term savings on energy bills. Energy-efficient models might have higher upfront costs but can save you money over time.


Warranty: Look for water heaters with solid warranties to ensure you're covered in case of malfunctions or issues.

Installation and Maintenance: Consider installation costs and requirements. Some water heaters might require modifications to your plumbing or electrical systems. Additionally, factor in maintenance needs for the chosen type of water heater.


Research Brands and Reviews: Look for reputable brands with positive reviews and a history of reliability.

Consult a Professional: If you're unsure, consult a plumbing professional. They can help you assess your needs and recommend the best type and size of water heater for your home.


Remember that choosing the right water heater depends on your specific household needs, budget, and local conditions. Take your time to research and consider all factors before making a decision.
