Propane powers a surprising amount of life in Pembroke, NH, and across the Greater Concord area, from furnaces and boilers keeping homes warm through brutal New England winters to backyard grills and fire pits that stretch summer well into fall.
Knowing how much propane you’re likely to use helps you budget smarter, avoid unexpected run-outs, and choose the right tank size for your household.
Here’s a straightforward look at how propane consumption works and how to estimate yours.
Propane is one of the most versatile home energy sources available to rural and suburban homeowners. In the Pembroke and Greater Concord region, common propane applications include:
Each appliance draws at a different rate, so total consumption is the sum of everything running in your home.
Every propane appliance has a Btu, or British thermal unit, rating, which tells you how much energy it burns per hour. One gallon of propane contains approximately 91,502 Btus.
Here’s the estimated average per-hour usage of propane for several common propane appliances.
Gallons per hour = Appliance Btu rating ÷ 91,502
| Appliance | Typical Btu/hour | Approx. gallons/hour |
|---|---|---|
| Propane furnace | 80,000–100,000 | 0.87–1.09 |
| Propane boiler | 100,000–150,000 | 1.09–1.64 |
| Water heater | 30,000–50,000 | 0.33–0.55 |
| Gas range/cooktop | 5,000–15,000 | 0.05–0.16 |
| Propane fireplace | 20,000–40,000 | 0.22–0.44 |
| Propane standby generator | 50,000–100,000+ | 0.55–1.09+ |
To estimate daily usage, multiply the gallons-per-hour figure by the average number of hours each appliance runs per day.
For example, a 100,000-Btu furnace running eight hours a day consumes roughly 8.7 gallons daily, or around 261 gallons over a 30-day month.
Propane doesn’t stop at the back door. Outdoor propane appliances are increasingly popular with Greater Concord homeowners looking to get more from their properties:
These appliances typically consume less propane than heating systems, but they add up across a season. Factor them in when sizing your tank.
Tank size depends on how many appliances you’re running and how frequently they operate. Johnny Prescott installs tanks ranging from 100 gallons to 1,000 gallons, and the right fit depends on your total estimated consumption.
A quick guideline for Concord-area homeowners:
Propane burns cleaner than oil, delivers more Btus per dollar than electric resistance heating, and works reliably even when the power grid doesn’t. For homeowners in rural areas, where natural gas lines don’t reach, propane offers the performance of gas with the flexibility of on-site storage.
Understanding your consumption is step one. Step two is making sure you never run out.
