The first step in making a wise purchase is understanding your household's hot water requirements. Most households use an average of 64 gallons of hot water per day, but this number can vary based on family size, lifestyle, and peak usage times. For example, a family of four may need between 75-100 gallons daily if everyone showers in the morning.
To calculate your demand, consider the following:
For instance, if your family of four has two showers in the morning, washes clothes and dishes each day, your calculations might indicate needing a heater that can provide at least 100 gallons of hot water daily. Knowing this will guide your heater capacity choice.
Once you understand your hot water needs, selecting the right capacity for your external gas water heater becomes essential. Water heaters are commonly available in capacities ranging from 30 to 100 gallons. Choosing a heater that is too small could leave you scrambling for hot water during peak times, while an oversized unit could waste energy and inflate your bills.
Another critical component is understanding fuel efficiency ratings. The Energy Factor (EF) is a common metric that indicates how efficiently a water heater converts energy into hot water. An EF rating closer to 1.0 means better efficiency. Generally, you should aim for a water heater that has an EF of at least 0.67, ensuring that you’re maximizing the energy you use.

Consider a household that previously had a gas water heater with an EF of 0.55. They used around 80 gallons a day. Their monthly gas bill was approximately $150. After switching to a model with an EF of 0.70, they noticed a reduction in their bill to about $120, saving them around $360 annually. Such savings can significantly offset the initial investment costs.
Safety is paramount when selecting an external gas water heater. Look for models with built-in safety features such as:
Prices for external gas water heaters can vary widely based on size, efficiency, and brand. Entry-level models can start around $600, while high-end models may exceed $2,000. It’s essential to balance quality and features with your budget. Consider both the initial purchase price and the long-term operating costs to make a sustainable decision.
Armed with this knowledge, you're now ready to choose the right external gas water heater for your needs. Consider creating a shortlist of models based on your household needs and budget. Visit local home improvement stores or trusted online retailers to compare options and read customer reviews.
If you're still uncertain, consult with a professional plumber or HVAC specialist who can provide personalized recommendations. By following these steps, you'll ensure that you make an informed choice that offers comfortable hot water in your home for years to come.
