About GasFireCost

GasFireCost (gasfirecost.xyz) is an independent unofficial calculator for natural-gas and propane fireplace running costs. It sits in Đạt’s home-energy planning fleet — not a utility, HVAC OEM, or licensed installer.

Purpose. Turn fireplace BTU input, efficiency, and local fuel prices into hourly / seasonal dollar estimates so you can compare NG vs LP and size expectations before a service call.

Curator. Đạt — independent publisher of this gas-fireplace running-cost calculator. Role: maintain BTU→therm/gallon formulas, prefer nameplate ratings over marketing copy, and keep NG vs LP comparisons estimate-only. Contact: hello@gasfirecost.xyz.

Planning estimates only — not financial advice. Fuel tariffs, venting, and appliance nameplate ratings vary. Confirm with your bill and a qualified technician.

Some instructional wording and page structure may be AI-assisted drafts; BTU math and fuel-cost formulas are curated from documented sources and reviewed before we ship updates.

Explicit formulas stay on Methodology — we do not dilute them here.
