Best way to measure gas consumption???

AdmiralYoda

Okay guys, just a homeowner here wanting to try and measure fuel consumption after some changes to my boiler.

I lowered the pressure, new Vaporstat, other maintenance items etc.

I'm thinking read the gas meter at the start and end of some period of time and then figure out the heating degree  days for that period.  Then I will know cubic feet of gas per degree day.

Then I can compare this to a previous gas bill for comparison.

Any other thoughts?

That should be quite accurate, provided that any non-heating gas loads in the house are similar between periods: water heater, range, clothes dryer, etc.

you can compensate approximately  for the non-heating gas loads by subtracting your usage during the non-heating months of the year; however, since incoming cold water tends to be colder in the winter, if you have a gas water heater it will use a bit more fuel in the winter months.

Recommend you login to you local gas supplier site to download utilization date Both Washington Gas and Columbia Gas in area provide gas utilization by month with average temperate. Very useful to compare usage based on average temperature, daily utilization and same month performance from 2020.
