What size gas meter do you need for your house to use a 333000 BTU pool heater?

To determine the appropriate gas meter size for a 333000 BTU pool heater, consider the following factors:

- The maximum gas consumption rate of the pool heater: This information can be found in the pool heater's specifications or manual.

- Local gas utility regulations: Gas meter sizes may be regulated by local gas utilities, so it's important to check with your gas supplier for specific requirements in your area.

- Safety margin: It's recommended to select a gas meter with a capacity slightly higher than the maximum gas consumption rate to ensure adequate supply during peak demand.

As a reference, a 333000 BTU pool heater typically requires a 1-inch gas meter. However, it's crucial to consult with your gas utility provider or a licensed plumber to determine the exact gas meter size that meets your specific needs and complies with local regulations.

Here are some general guidelines based on BTU ratings and gas meter sizes:

- Up to 150,000 BTU: 3/4-inch gas meter

- 150,000 - 250,000 BTU: 1-inch gas meter

- 250,000 - 350,000 BTU: 1-1/4-inch gas meter

- 350,000 - 450,000 BTU: 1-1/2-inch gas meter

Remember, these guidelines are approximate, and the actual gas meter size required can vary depending on several factors, including the heater's efficiency and the gas pressure in your area.
