Your home's gas appliances all compete for the same fuel supply, and an undersized meter can cause performance problems or generator failures. Use our free Gas Appliance BTU Calculator to estimate your home's total gas demand and determine whether you may need a meter upgrade. [Click here to learn how to read the size of your current gas meter](https://guardianhomegenerators.com/blog/is-your-gas-meter-big-enough-for-a-whole-home-generator).   Select your gas appliances, enter the quantity of each, and adjust the BTU values to match your equipment. We'll calculate your total gas load to help estimate the gas supply capacity needed for your home. When you call for your meter upgrade, tell them your required capacity.  The most common meter sizes are 630,000 , 800,000, 1,000,000, and 1,500,000 BTU/hr.  There are high-pressure gas meters (pounds) or low-pressure gas meters (ounces).  Generally, you want to stay with the same meter type you currently have.  A low-pressure meter has a white face behind the dials, and a high-pressure meter has a red face. Default BTU/hr values are estimates only. For the most accurate results, use the BTU/hr ratings listed on the appliance nameplate, specification label, or owner's manual.  NOTE:  1,000 BTU/hr also equals 1 C.F.M (Cubic Feet per Minute).  300,000 BTU/hr = 300 C.F.M.   **Please note**, the calculation requirements assume every gas appliance is operating at full capacity simultaneously, which is unlikely to occur in normal household use.  Calculations should be reasonably close, but they don't need to be exact.  For example, each burner on a cooktop is 500 - 15,000 BTU.  The cooktop calculation assumes all burners are on at the same time.  And a homeowner will rarely be operating a pool heater while the generator is running.   Appliance Qty BTU/hr input   Summary 0 appliances selected Select appliances above to see your load summary.

The homeowner is responsible for verifying actual appliance loads and total calculations. Default BTU values are typical appliance inputs. Actual values will vary by model — check your equipment's nameplate or spec sheet and adjust as needed.
