Assess heat tracing energy use
Heat According to Demand
Energy use follows heat losses and actual operating hours. Pro Therm assesses insulation, setpoints, controls and circuit structure together. We identify technically appropriate changes while preserving required freeze protection and process temperatures.

A nominal value in W/m does not automatically describe annual consumption. Operating hours, ambient conditions, pipe temperature and control behaviour determine actual energy use. Assessment records the measurement period and operating conditions. Self-regulating cable output is particularly temperature dependent.
03
Set temperatures from process requirements
An unnecessarily high setpoint can increase heat loss. The permissible value must nevertheless follow the fluid, process and protection function. Operating and shutdown …
An unnecessarily high setpoint can increase heat loss. The permissible value must nevertheless follow the fluid, process and protection function. Operating and shutdown phases may have different requirements. Changes are agreed with the operator rather than applied as a universal reduction across all circuits.

Prioritise measures by benefit and effort
Small insulation repairs or setting corrections differ from circuit restructuring or controller replacement. We distinguish technical necessity, expected effect, …
Small insulation repairs or setting corrections differ from circuit restructuring or controller replacement. We distinguish technical necessity, expected effect, investment and operational disruption. Savings are assessed only from traceable data; no fixed percentage is promised.

Before a measure, define what will be measured: one circuit or an entire distribution panel, energy or instantaneous power, over which period and operating states. Record setpoints, enable signals and outdoor temperatures as well. These inputs allow changes to be interpreted.
Installed kW multiplied by 8,760 hours represents assumed continuous operation, not measured consumption. An economic assessment uses credible operating hours, suitable measurements, electricity price and implementation cost, with differences in production and weather conditions made explicit.

How much energy can be saved?
This depends on the starting condition and operating circumstances. A credible fixed percentage requires reliable data.
Is replacement with self-regulating cable enough?
Not automatically. Heat losses, target temperature, controls and operation determine demand. Technology is selected for the task.
Can heating be switched off in summer?
Only where process and protection requirements permit. Temperature maintenance and freeze protection may need different enable conditions.
What measurements are useful?
Energy or current with time period, temperatures, setpoints and operating hours. A single value without context has limited meaning.

Wet insulation, open transitions and uninsulated fittings increase demand. A control adjustment cannot remove these losses. We therefore assess the thermal condition before replacing heating equipment. Insulation material or thickness changes are coordinated with the heating system's temperature limits.
If insulation needs renewal or improvement as part of an optimisation project, we can offer this service with partner companies. The measure is coordinated with heating, sensor positions and accessible fittings. Its effect on energy use is assessed against the actual operating conditions.

Unsuitable sensor locations can cause excessive energised time or cold areas. We assess the measured temperature and whether it represents the circuit. Enable signals and alarms are also reviewed. The appropriate strategy follows the installation, not just the controller brand.

Before-and-after comparisons need comparable conditions. Colder weather or longer production hours can increase consumption despite an effective improvement. Measurements are therefore linked with temperature and operating time. Required freeze and process protection remain the deciding criteria.

Standards reference (checked 14 October 2026): ISO 12241:2022, adopted in Germany as DIN EN ISO 12241:2022-09, provides thermal-insulation calculation rules primarily for steady-state conditions. Heat-up assessment additionally considers stored energy and heat transfer over time.
