Fluidit Heat™
Modeling Platform for District Energy Systems
See which consumers, pump stations, and pressure-difference control nodes become critical when you change the supply temperature curve, across the full year and not just on one winter design day.
Fluidit Heat runs fast, explicit time-series simulations on your full network, so you can validate the temperature reduction before decision making.
References
The temperature reduction looks fine on paper. The hydraulics say otherwise.
A few degrees off the supply-temperature curve lowers losses and CO₂. But the extra flow shifts pressure losses into parts of the network nobody expected. Static design-day studies do not catch this.
By the time the network shows you the problem, you are already past it.
That is where most low-temperature projects stall. Not in the strategy slide, but at the hydraulic details.
Pressure difference disappears at the wrong control nodes
The margin you thought you had is not there once flows rise across the network.
Pump duty shifts in unexpected places
Stations that looked stable on the design day start operating close to the limit during normal seasonal operation.
Critical consumers lose heat before anyone notices
Power deficit shows up at the customer long before traditional planning models expose the issue.
Purpose-built for district energy networks. Built for engineers.
Fluidit Heat helps district heating engineers understand what actually happens when supply temperatures change across the network.
Run fast annual time-series simulations to identify where pressure, flow, pump duty, or consumer delivery become critical before operational issues appear in the field.

Built for the questions you cannot answer with a design-day study.
Every feature in Fluidit Heat™ addresses a real operational problem. From supply temperature curve design to critical node detection, the platform gives you the visibility engineers need to make confident decisions.
Hierarchical scenario management
Keep the baseline network untouched. Create low-temperature scenarios alongside the original model and compare them side by side across maps, tables, and network views.
Full-year time-series simulation
Run hourly simulations across the entire year to see how pressure, flow, temperatures, and delivered heat behave across changing operating conditions.
Detailed substation modeling
Model every consumer substation individually with separate heating and hot water demand behavior. Identify which consumers lose margin first when temperatures change.
Pump station and production validation
Test pumping strategies, control nodes, and production plans against the new temperature regime before operational bottlenecks appear in the network.

FAQ
Questions district heating engineers usually ask before evaluating a new modeling platform.
Most hydraulic tools simulate a single operating condition. Fluidit Heat runs full annual time-series simulations, so you can see how the network behaves across changing weather, demand, and operational conditions throughout the year.
No. Most utilities start from existing network topology and operational data. Fluidit Heat supports integrations with GIS, SCADA, NIS, and historian systems to accelerate model creation and validation.
Lower supply temperatures change pressure losses, flow behavior, pump operating points, and consumer delivery margins across the network. Fluidit Heat makes those changes visible before they become operational issues.
Yes. Every substation can be modeled separately with its own heating and domestic hot water demand behavior, allowing engineers to identify which consumers become critical first.
Fluidit Heat is primarily used by district heating engineers, thermal network planners, utilities, and engineering consultancies working on network optimization, modernization, and low-temperature transition projects.
