Tank Heater Sizing Calculator

Calculate required heater duty (BTU/hr) to heat fluid in oilfield tanks and treaters. Formula: Q = V × ρ × Cp × ΔT / t, plus heat loss allowance.

Notes

Heat loss factor accounts for radiation and convection losses from the tank walls. Typical values: insulated tanks 10-15%, bare tanks 20-30%. Gas usage assumes 80% burner efficiency and 1,000 BTU/SCF natural gas.
