From diagnosis to implementation: how a complete project with i-TES thermal battery is born

In a rapidly evolving energy landscape, the ability to strategically integrate smart technologies makes all the difference. That’s why more and more companies, public administrations, and design firms turn to companies like ours to develop complete thermal storage projects that combine efficiency, flexibility, and sustainability.

A project with a PCM thermal battery goes beyond simply installing a device: it begins with a structured process, starting from understanding the needs and resulting in a tailor-made system, perfectly integrated into the plant.

From initial consultation to diagnosis: the starting point

Every i-TES project begins with a listening and analysis phase.

Initial technical consultation

The first contact is often with designers, ESCo, or technical managers. The i-TES team assesses:

• the type of system (existing or new)
• thermal flows and their variability
• savings and decarbonization goals
• any regulatory, architectural, or logistical constraints

This phase is not a generic energy consultation, but specialized support to understand where and how thermal storage can make a difference.

Diagnosis and technical evaluation: plant context analysis

In this phase, real data is collected and heat demand profiles are analyzed. This allows to:

• accurately size the thermal battery
• assess the energy saving potential
• simulate operation under various usage conditions
• determine the economic return on the investment

All of this is carried out by a technical team composed of specialized engineers capable of deeply analyzing field data.

Design and sizing of the PCM thermal battery

Based on the diagnosis, the design phase begins. This includes:

1. Choosing the size, operating temperature, and type of PCM thermal battery (modular, wall-mounted, outdoor...)
2. Hydraulic circuit configuration
3. Defining the charging strategy (e.g., with heat pump or renewable source)
4. Analysis of the plant layout and available space

The goal is to ensure maximum integration without overhauling the existing system, reducing time, cost, and complications.

Implementation and installation support

I-TES doesn’t stop at product delivery.

During the implementation and start-up phase, the team:

• provides functional and hydraulic diagrams
• provides technical documentation and specialized support. In more complex systems, it offers a customized control and regulation system, designed according to the specific plant requirements.

The result is a smooth commissioning, with a constantly available technical partner.

Why thermal storage is strategic for efficiency

Integrating a thermal battery into a system doesn’t just mean saving energy, but also:

• cutting power peaks
• optimizing the use of the heat pump
• decoupling heat production and usage
• better leveraging renewable sources (e.g., photovoltaics or cogeneration)

All of this with a solution that is combustion-free, wall-mountable, slim, and safe.

The advantages of an i-TES PCM thermal battery

• Easy integration into new or existing systems
• Space-saving format, also suitable for niche or balcony installations
• No direct emissions or combustion
• Modular technology that is easily scalable
• Compatibility with heat pumps, solar thermal, photovoltaics, and heat recovery systems

When thermal storage makes sense

The PCM thermal battery is particularly effective in these scenarios:

• Renovations with limited space or architectural constraints
• Systems with intermittent and variable thermal loads
• Hospitality and public facilities with high domestic hot water demand
• Companies and SMEs aiming to improve energy class

Summary: the key steps of an i-TES project

1. First contact and specialized technical consultation
2. Energy diagnosis and data collection
3. Sizing of the PCM thermal battery
4. Consulting for the ideal hydraulic configuration
5. Supply

In conclusion, integrating a thermal storage system into your plant isn’t always a “plug & play” choice. When the solution requires customization, it’s essential to rely on a technical partner with field experience and the ability to fully understand the project.

With i-TES, you get much more than a supplier: you get a project partner who supports you from diagnosis to implementation, bringing innovation, expertise, and concrete results.
