Understanding Your Needs

"What size do I need?" many people ask. It’s essential to determine the amount of hot water your household requires. If you have a large family, you’ll need a larger unit to meet the demand. Conversely, a smaller unit may suffice for a single person or a couple.

Types of External Gas Water Heaters

There are two main types of external gas water heaters: tank and tankless. “What’s the difference?” you might wonder.

1. Tank Water Heaters: These heaters store a specific amount of hot water. They can provide large amounts of hot water at once, but they consume energy constantly to maintain the temperature.
2. Tankless Water Heaters: These units heat water on demand. This means you won’t run out of hot water, but they may struggle to provide enough for multiple outlets at once.

Energy Efficiency

When selecting an external gas water heater, energy efficiency is crucial. “Why is that important?” you might ask. A more efficient unit saves you money on your utility bills in the long run.

Check the Energy Factor (EF) rating. Higher numbers indicate better efficiency. A gas water heater typically has an EF of 0.5 to 0.9.

Installation Requirements

Installing an external gas water heater can be complex. “Do I need a professional?” you might wonder. Yes, it is often necessary to have a licensed plumber or technician handle the installation. Proper setup ensures safety and efficiency.

Safety Features

Safety should never be overlooked. Look for the following features:

• Thermal relief valves to prevent overheating.
• Flame failure devices that shut off gas flow if the flame goes out.
• Pressure relief valves to avoid excessive pressure buildup.

“Are these features common?” you might ask. Yes, most quality models come equipped with them.

Price Consideration

Budget is always a factor. The price of an external gas water heater can vary widely. “How much should I spend?” Generally, you can expect to pay between $500 and $1,500 for the unit alone, not including installation costs.

Consider the long-term savings from efficiency. Sometimes, spending a bit more now can save you money later.

Brand Reputation

Before making a decision, research different brands. “Which brands are reliable?” Look for customer reviews and ratings. Popular brands often have better warranties and customer support.
