Verify the inputs
Measure or document each input. If a value is only an estimate, record its source and test a conservative alternative.
Frost & ground/ CALCULATOR
Heat-trace energy use
Estimate connected load and energy use for a thermostatically controlled heating cable.
FROM ESTIMATE TO ACTION
Use the result, not just the number.
Keep the calculation traceable
Save the input link or copied result together with the date, units and assumptions. A number without its inputs cannot be checked later.
Confirm the decision
Compare the estimate with the related guide, current product data and requirements that apply at your location before buying or building.
Inputs to verify
- Heated cable length (m)
- Use the installed heated length, excluding cold leads.
- Cable power rating (W/m)
- Use the applicable rating at the design condition.
- Average duty cycle (%)
- Estimated fraction of enabled time at full rated power.
- Enabled hours per day (h/day)
- Hours per day the control permits operation.
- Number of days (days)
- Length of the scenario.
