Why Choose an External Gas Water Heater?

External gas water heaters offer numerous advantages. They typically heat water faster than electric models and can be incredibly cost-effective. Also, they free up indoor space since they are installed outside.

1. Assess Your Hot Water Needs

Before anything else, think about your household's hot water usage. Ask yourself:

  • How many people live in my home?
  • What appliances use hot water?
  • How many showers do we take daily?

These questions will help you determine the capacity you need in an external gas water heater.

2. Check Your Energy Source

You'll need to know what type of gas supply you have. Is it natural gas or propane? This decision impacts your heater choice, as some models are designed for specific gas types. “Can I convert it?” you might wonder. Some units can switch between gas types, but it's essential to verify first.

3. Look for Efficiency Ratings

Energy efficiency is critical. Look for the energy factor (EF) rating. The higher the rating, the better the efficiency. “What does this mean for my bills?” Good quality external gas water heaters can lead to lower utility costs. Everyone loves saving money!

4. Consider Size and Space

Space matters too. Measure the area where you plan to install the heater. Is there enough room for proper ventilation? Ensure that the size of the external gas water heater fits comfortably without causing hazards.

5. Research the Brands and Models

Take some time to investigate various brands. Look for customer reviews and ratings. “Which brand is most reliable?” Some brands are recognized for their durability and customer service. Choose wisely!

6. Evaluate Safety Features

Safety should always come first. Ensure the external gas water heater has necessary features like automatic shut-off valves and vents. “How can I check this?” Not every model includes these. Always read the specifications carefully.

7. Budget for Installation

Installation costs can add up. Make sure to budget not just for the heater but also for professional installation. “Do I really need a pro?” Unless you're experienced in plumbing and gas installation, hiring a professional is best. It ensures safety and compliance with local codes.

8. Warranty and After-Sales Support

Finally, look at the warranty. A good warranty reflects the manufacturer’s confidence in their product. “What if something goes wrong?” Knowing you have support can give you peace of mind.

Conclusion

Choosing an external gas water heater doesn't have to be a daunting task. By considering your hot water needs, energy source, and efficiency, you can make a sound decision.
