EQUILOG: Thermal balancing based on the actual operation of installations

The finding

Today, the majority of hydraulic balancing are carried out using theoretical data:

  • calculated flows,
  • Design assumptions,
  • Pressure measurements.

👉 Or, in reality:

  • the installations evolve over time,
  • theoretical flow rates are often unknown or inaccurate,
  • The networks present significant line losses,
  • The actual thermal requirements do not correspond to the initial calculations.

 

➡️ Result:
Imbalanced networks despite “compliant” balancing.

The solution

A real-based method

EQUILOG is based on a different approach:

👉 Analyse the real thermal behaviour of the network
rather than relying solely on theoretical hydraulic quantities.

The balancing is carried out from the return temperatures, allowing you to:

 

  • reflect the real needs of the building,
  • integrate the thermal losses in line,
  • take into account the interactions between circuits,
  • adjust the flows coherently.

A universal method

Unlike traditional approaches, the EQUILOG method is applicable:

  • ✔️ with or without bleed valves
  • ✔️ on existing or modified networks
  • ✔️ on radiators, underfloor heating, risers
  • ✔️ without prior knowledge of theoretical flows

 👉 It adapts to the network as it actually works.

Ideal for existing [situations/premises/structures]

EQUILOG makes perfect sense in the most common situations:

  • old installations without documentation,
  • networks that have evolved over time,
  • persistent imbalances despite previous adjustments,
  • impossibility of measuring or verifying flow rates.

Right Where conventional methods reach their limits,
EQUILOG provides an operational solution.

A global thermal approach

The analysis of return temperatures allows us to:

  • understand the real behaviour of circuits,
  • identify imbalances,
  • adjust the flows according to needs,
  • Optimise heat distribution.

We no longer set up a network “on paper”,
It's adjusted as it actually works.

Integration of line losses

Unlike methods based solely on pressure:

 heat losses in the network are taken into account,

  • distribution-related discrepancies are incorporated,
  • the setting reflects the installation's energy reality.

A method suited to current energy requirements

EQUILOG is particularly relevant in the following contexts:

  • of energy renovation,
  • performance optimisation,
  • of EEE devices,
  • Low-temperature operation (heat pump, condensation).

It allows for a balancing that is consistent with the actual operation of the building.
