My gas usage seems constant for the past 6 months (summer/fall time) so perhaps this is normal usage for my house but my gas company says my gas usage is Tier 2, which is a higher amount per therm.

Before I hire someone to inspect or before I spend a few dollars buying a gas leak detector from Amazon, I wanted to know if 1/2 a therm per day sounds reasonable? The items in the house that use gas are:

• stove/oven
• water heater (50 gallon tank)
• dryer
• fireplace (not used or turned on since it's summer/fall time)
• gas line outside for a grill but we don't have one

I'm not too privy to how my local utility company sets up the tiers but the fact that I'm already at Tier 2 before the winter comes concerns me. I would expect more gas usage during the winter and thus being pushed up to Tier 2 but not right now when I'm just normally using the gas appliances.

• The stove we use almost every day to cook dinner or heat water for tea.
• The water heater I set to 120F or 130F? Not sure the temp but it's at the second lowest setting so I'm not sure but it's probably around that temp
• The dryer we use once a week when we have a load of laundry. Not sure the temp in Fahrenheit but we dry on Low heat for about 1 hr
• The fireplace isn't used since it's summer
• The gas line outside isn't used and is in the closed position from what I can tell.

In any case, hopefully someone can tell me if this sounds reasonable for the appliances and usage we're using.
