Protected result

Preliminary calculation: the full result requires technical registration. It does not replace a complete thermal review, W/cm² selection, heater type selection, circulation, insulation or electrical safety checks.

Calculation criteria

WHAT IT CONSIDERS

Base power is calculated from mass, specific heat, temperature rise and time. Then an indicative margin is added for losses and real operating conditions.

01

Initial heating

m × Cp × ΔT divided by the available time.

02

Losses

The margin helps estimate losses through the tank, environment, insulation and heat transfer.

03

Final selection

Then the heater type, sheath, flange, connection and allowable watt density are defined.

04

Quotation

The result can be copied and sent to the technical team.
