solar thermal accessories

How do you transform a standard solar thermal system into a high-efficiency one, capable of ensuring maximum performance and longevity for years? The answer is not only the quality of the panels or storage, but is hidden in the details: in the precision, reliability, and technology of solar thermal components. These elements, often considered secondary, are actually the real protagonists that ensure the correct functioning, safety, and energy optimization of the entire system. From the management of the heat transfer fluid to protection against overpressure, each component plays a crucial role. Novasfer designs and manufactures a range of components for solar thermal system designed to meet the specific challenges of this sector, providing installers and designers with high-performance and durable solutions.

Flow meters and control devices: The heart of precision

A solar thermal heating system operates in a dynamic balance, where the correct circulation of the heat transfer fluid is essential to maximize heat exchange. A flow that is too slow cannot effectively transfer the energy captured by the panels, while a flow that is too fast does not allow the fluid to heat up sufficiently. Precise management of this parameter is the key to efficiency. Our components for solar thermal are dedicated to the control are designed to provide accurate data and allow for fine-tuning of the system.

Flow meters for perfect system balancing

The flow meter is one of the most important accessories for a solar thermal system for monitoring and calibration. This tool allows for real-time visualization of the amount of fluid flowing through the circuit, enabling the installer to perfectly balance the different sections of the system and set the circulator speed optimally. Novasfer flow meters are made with materials resistant to high temperatures and corrosion caused by glycol fluids, ensuring precise and reliable readings over time. Their installation not only facilitates commissioning but also becomes an important diagnostic tool for identifying any anomalies, such as blockages or pressure drops, that could compromise performance. Choosing a quality flow meter means having full control over the system’s efficiency, transforming a hypothetical operation into a measurable certainty.

Safety and maintenance systems: protecting your investment

A solar thermal heating system is an environment that works in extreme conditions, subject to high temperatures and pressures, especially during periods of summer stagnation. Solar thermal system components dedicated to safety must guarantee the reliability and be ready to intervene at any time. Novasfer has developed a complete range of thermal accessories dedicated to protection, built according to the European regulations.

Automatic air vents and degassers for maximum efficiency

Air is the number one enemy of a closed hydraulic circuit. Its presence can cause noise, corrosion, cavitation phenomena in the pump, and, above all, a drastic reduction in heat exchange. In a solar system, where the fluid can reach high temperatures, the air bubbles production is a common phenomenon. The automatic air vent is the component that prevents these type of issues. Installed at the highest point of the circuit, this device automatically outflow the air accumulated in the circuit, keeping the heat transfer fluid pure and ensuring that only the liquid comes into contact with the exchange surfaces. Our venting kits are designed specifically for the solar applications, with materials and gaskets able of withstanding high temperatures and the chemical composition of antifreezes, ensuring secured operation and a long lifespan. These components of a control unit for thermal solar systems are essential for reduced maintenance and constant efficiency.

Safety valves and filling groups for overpressure protection

During stagnation (when there is solar radiation but no heat withdrawal), the temperature in the solar collector can exceed 200°C, causing fluid evaporation and a rapid increase in pressure. The safety valve is the last safeguard component that protects the entire solar thermal heating systems and its components from damages. Calibrated to a specific pressure, it opens automatically to release excess pressure, closing once conditions return to normal. Novasfer valves are certified and tested to ensure precise and repeatable intervention. Combined with filling groups, they facilitate pressure setting and circuit maintenance, making system management simpler and safer for the professional.

Connection components and heat transfer fluid management

The robustness and reliability of a system also depend on the quality of its connections. Fittings, valves, and solar collectors must guarantee a perfect seal over time, resisting to thermal shock, high pressures, and the chemical aggression of glycol fluids. Using components for solar thermal system not specific to this application is a mistake that can lead to leaks, failures, and costly repairs. Our range of solar thermal heating system components is the result of decades of experience in brass processing and the design of hydraulic solutions. Novasfer maintains total control over the supply chain, from stamping to brass processing, ensuring extremely high-quality standards for every single piece. This direct control allows us to create custom fittings, ball valves, and components that perfectly meet the needs of the solar sector.

Fittings and valves specific for high temperatures and special fluids

The fittings used in solar thermal heating systems must offer much more than a simple mechanical connection. They must be equipped with gaskets (such as FKM or EPDM for high temperatures) and be able to maintain elasticity and sealing even after countless heating and cooling cycles. The brass used for our solar thermal system components is selected for its excellent mechanical strength and corrosion resistance. Our shut-off valves are designed for safe isolation of various circuit sections during maintenance, with ball mechanisms that ensure perfect closure and a long operating life even in demanding working conditions.

Kits and integrated solutions for the professional installer

We understand the daily challenges of installers: limited time on site, the need to minimize the possibility of errors, and ensuring an impeccable final result. For this reason, in addition to individual components of solar thermal system, we offer integrated solutions and pre-assembled kits that simplify installation and ensure perfect compatibility between the various elements. These systems are the result of our vision focused on practicality and efficiency, combining multiple functions in a single compact and easy-to-assemble product. This design philosophy is at the heart of our offer: for more complex systems, discover the complete catalog of circulation units for systems, where integration reaches its highest level.

The quality of materials: why brass is the winning choice

Brass is the best material for high-quality hydraulic components, and in the solar thermal system sector, its properties are even more valuable. Its excellent thermal conductivity, corrosion resistance (especially with specific low-lead alloys), and mechanical robustness make it ideal for withstanding the typical stresses of these systems. Unlike other materials, brass does not degrade with exposure to UV rays or high temperatures and guarantees dimensional stability that prevents leaks. All our production of components for solar thermal systems is based on this material, processed with CNC machines to obtain minimal tolerances and perfect finishes. This experience is also made available to our OEM partners.

Why the quality of accessories determines the success of a solar thermal system

Investing in high-quality solar thermal heating system components is not an additional cost, but the best assurance of the performance and durability of the entire system. A precise flow meter, a reliable safety valve, an efficient air vent, and watertight fittings are the elements that, working in synergy, allow the system to always operate at its peak performance. Novasfer is committed to providing the plumbing and heating sector not with simple products, but with complete and reliable solutions, designed by technicians for technicians.
