Energy efficiency in heating systems

Energy efficiency is now a central topic in modern construction and HVAC design.
Every renovation project, every system upgrade and every component installed represent a step toward true energy saving — and toward a more sustainable future.

Reducing consumption is not just about lowering energy bills. It means improving system performance, ensuring stable indoor comfort and extending the lifespan of heating equipment. In a context where energy prices continue to rise, even a minimum reduction can make a significant difference.

How important is energy saving today?

In recent years, smart energy management has become a clear priority at the European institutions.
The new EPBD (Energy Performance of Buildings Directive), in force since May 2024, establishes that by 2030 all new buildings must be zero-emission, with an earlier deadline of 2028 for public buildings.

In Italy, the Ecobonus 2025 confirms tax deductions of 50% for primary residences and 36% for other properties, supporting the upgrade of heating systems, boilers and energy-efficient technologies.

What does energy saving really mean?

Energy saving is more than simply consuming less.
It involves:

• conscious and informed energy use,
• preventing unnecessary waste,
• choosing efficient, high-performing technologies.

A modern heating system must ensure consistent comfort, balanced heat distribution, and energy use based strictly on real needs.

According to the GSE – Gestore dei Servizi Energetici, heating accounts for around 70% of total energy consumption in Italian households.
Optimising thermal management, therefore, is both an ecological and a highly strategic economic choice.

How do you achieve an efficient heating system?

An efficient heating system is the result of multiple elements working together:

• Proper system design, taking into account heat distribution and operating temperatures.
• High-quality components, built with durable materials engineered to maintain performance over time.
• Regulation and balancing systems, ensuring the desired temperature with minimal energy consumption.

At Itap, we design and manufacture solutions that support energy efficiency and sustainability: distribution groups, manifolds and thermostatic valves, suitable for both traditional and next-generation heating systems.

Itap distribution groups for energy saving

Among the key components of an efficient heating system, the distribution group plays a crucial role by regulating and balancing the flow of water between the heat generator and the circuits.

Itap offers two versions, designed to meet different system requirements.

Fixed-point distribution and regulation group

Designed for radiant systems, it keeps the temperature of the heating fluid constant — regardless of outdoor conditions or the thermal demands of individual rooms.

Main advantages:

• constant thermal efficiency and reduced waste;
• protection of condensing boilers from overheating;
• prevention of thermal shocks in distribution circuits;
• compact installation and minimal maintenance.

Discover more details in the technical product page.

Direct distribution group

Ideal for traditional radiator systems, it ensures a direct flow of the heating fluid to the terminals, without mixing.

Main advantages:

• maximum thermal efficiency with no dispersion;
• quick and easy installation;
• lower operating costs;
• compatibility with existing systems.

Pairing the Itap distribution group with the Itap distribution manifold with integrated hydraulic separator and adjustable by-pass ensures uniform heat distribution across all circuits, reduced mechanical stress on the circulation pump, increased stability and overall system efficiency.

This synergy results in a more balanced, reliable and energy-efficient heating layout.

Itap thermostatic valves for higher efficiency

Thermostatic valves and heads are among the most effective tools for reducing energy consumption and improving indoor comfort.

They automatically regulate the flow of hot water into each radiator based on the selected temperature. When the room reaches the desired level of heat, the valve reduces or stops the flow, preventing waste and maintaining stability.

How thermostatic valves work

Each thermostatic valve consists of:

• A nickel-plated brass body, controlling the passage of the heating fluid;
• A modulating shutter, opening and closing according to room temperature;
• A thermostatic head with a sensitive bulb, detecting air temperature and adjusting the water flow accordingly.

Main advantages:

• Independent control of each room;
• Lower energy consumption, thanks to automatic modulation;
• Stable, uniform temperature in every space;
• Easy installation, even on existing systems and in combination with Itap groups and manifolds;
• Guaranteed savings: according to ENEA, reducing room temperature by just 1°C can save up to 6% on annual energy consumption.

FAQ

What does energy saving mean?
Energy saving means not only consuming less, but managing energy intelligently and consciously — choosing efficient technologies, avoiding waste and optimising system performance.

Why is energy saving important?
It improves system performance, reduces consumption and lowers operating costs without compromising comfort. It also extends system lifespan and supports environmental protection, especially considering that heating accounts for around 70% of household energy use in Italy.

What is a distribution group?
It is the component that regulates the temperature and flow rate of the heating fluid across the circuits, optimising heat distribution.

What is the difference between a direct group and a fixed-point mixing group?
The direct group is ideal for traditional radiators and supplies fluid without mixing, while the fixed-point group maintains constant temperature in radiant systems, regardless of outdoor variations.

Why install thermostatic valves?
To precisely regulate temperature in each room, reduce energy waste and improve comfort.
