Longmont’s Guide to Choosing the Right Size Water Heater

How to Select the Perfect Water Heater Size for Your Home

Choosing the right size water heater for your Longmont home is crucial to ensure that you have enough hot water for your family’s needs without wasting energy. An undersized water heater won’t meet your daily demands, while an oversized one will increase your utility bill unnecessarily. Here’s how to determine the suitable size for your household’s hot water requirements.

Understanding Water Heater Capacities

Water heaters are typically available in various sizes, and their capacity is measured in gallons. For tank water heaters, common sizes range from 30 to 80 gallons, while tankless water heaters are measured by the flow rate of water they can heat, known as gallons per minute (GPM). The right size for your home largely depends on the number of occupants and your simultaneous usage needs.

Estimating Demand for Tank Water Heaters

To choose the right size tank water heater, start by estimating your household’s peak hour demand — the hour each day when your hot water usage is highest. Here’s a quick reference for average usage:

• Baths: 20-30 gallons
• Showers: 10-25 gallons
• Dishwashing by hand: 4 gallons
• Washing machine: 20-30 gallons

Add up the total amount of hot water your household uses during this peak hour to get a sense of the capacity you’ll need.

Determining Size for Tankless Water Heaters

Tankless water heaters are rated by the maximum temperature rise possible at a given flow rate. To find the right size, determine the total flow rate for all devices you might use simultaneously and add them up. For example:

• Shower: 2.5 GPM
• Kitchen Sink: 1.5 GPM

Thus, if you expect to shower while someone is washing the dishes, you would need a water heater that provides at least 4 GPM at your desired temperature rise.

Factors Impacting Size Requirements

Several additional factors should be considered when choosing your water heater:

• Hard Water: In areas with hard water, like Longmont, sediment can build up faster, potentially reducing water heating efficiency. Consider a slightly larger size or investigate water softening solutions.
• Simultaneous Uses: Consider your family’s habits. If multiple water-heavy devices are used simultaneously, opt for a higher capacity or flow rate.
• Future Needs: Think about future changes, such as additional family members or new appliances that might increase water usage.

Professional Assessment

While these guidelines can provide a general idea, each home is unique. It’s often beneficial to consult with a professional who can offer a more personalized assessment based on the specifics of your home and lifestyle. They can also help you consider other factors like energy efficiency and the latest technology that could influence your decision.

Conclusion: Tailor to Your Needs

Finding the right size water heater is about balancing your immediate hot water needs with consideration for energy usage and future demands. By carefully evaluating your household’s habits and discussing options with a professional, you can ensure that you select the most appropriate size for your Longmont home.
