Ariston

ItalyBoiler Spare Parts

Ariston is an Italian manufacturer of heating and water-heating systems, with a product line that extends into residential and light commercial boilers, water heaters, and their associated control and safety components. The brand, established in the 1930s and headquartered in Fabriano, Italy, has a long history in the European heating market and is recognized for its engineering focus on combustion efficiency and thermal management. For plant engineers and maintenance managers, Ariston's relevance lies not in complete boiler units alone but in the spare parts and subcomponents that keep those systems operational over their service life. 3G Electric supplies a range of Ariston boiler spare parts, including electronic ignition modules, ionization probes, temperature sensors, thermostats, and thermal safety devices—components that are integral to flame supervision, temperature regulation, and safe shutdown in gas-fired heating appliances.

About Ariston

The product families available through 3G Electric cover several critical functions in boiler operation. Electronic ionization ignition modules, such as the Ariston 569561, provide the high-voltage spark for burner ignition and simultaneously monitor flame presence via ionization current. This dual function is essential for safe combustion; if the flame is not detected within a specified time, the module interrupts gas supply. Temperature probes, including the Ariston 004N and the metal probe 950600, are resistive sensors that feed temperature data to the boiler's control board, enabling modulation of burner output and preventing overheating. Sanitary thermostats, like the ARX20 (part 564885), regulate the temperature of domestic hot water in combi boilers, ensuring consistent delivery while protecting against scalding. Thermal safety devices, such as the 16-10°C cutoff (part 570970), act as fail-safes that break the circuit if water temperature exceeds a set threshold, typically 100°C, providing a last line of defense against boiling or pressure buildup. City contact probes (part 990686) are used in systems that interface with district heating or external control signals, allowing the boiler to respond to demand from a remote thermostat or building management system.

For technical buyers, the key specifications of these components are their electrical ratings, temperature ranges, and mechanical compatibility. Ariston parts are designed to meet European standards for gas appliances, including EN 298 for automatic gas burner control systems, which mandates rigorous testing for flame detection and safety response times. The components are typically rated for 230V AC operation, with temperature sensors offering resistance curves that match Ariston control boards. IP ratings vary by component; for example, ignition modules are often enclosed to IP40, while probes may be rated for immersion in water. 3G Electric supports these lines by stocking genuine Ariston parts, ensuring that replacements match original specifications for form, fit, and function. This is critical because aftermarket or generic parts may have different resistance values or timing characteristics, leading to improper boiler operation or safety hazards. By supplying OEM components, 3G Electric enables maintenance teams to restore boilers to factory performance, reducing downtime and extending equipment life. The availability of these parts across global shipping routes means that facilities outside Europe can also source authentic Ariston components, maintaining consistency in multi-site operations.

Frequently asked questions

Common questions about Ariston from 3G Electric.

What is the function of the Ariston electronic ionization ignition module (part 569561)?

The Ariston electronic ionization ignition module (part 569561) serves two primary functions in a gas boiler: it generates the high-voltage spark to ignite the gas-air mixture, and it monitors the flame through ionization current. When the burner is active, the flame creates ions that allow a small current to flow between the electrode and the burner body. The module detects this current to confirm that combustion is occurring. If the flame is not detected within a few seconds after the gas valve opens, the module shuts off the gas supply to prevent unburned gas accumulation. This component is critical for safe boiler operation and is designed to meet EN 298 standards for flame supervision.

How does the Ariston sanitary thermostat ARX20 (part 564885) work in a combi boiler?

The Ariston sanitary thermostat ARX20 (part 564885) is a temperature sensor that monitors the temperature of domestic hot water in a combi boiler. It is typically a thermistor or a capillary-type thermostat that sends a resistance signal to the boiler's control board. The control board uses this signal to modulate the burner output, ensuring that the hot water is delivered at the set temperature, usually between 35°C and 60°C. If the water temperature exceeds a safe limit, the thermostat can also trigger a safety shutdown. This component is essential for maintaining consistent hot water supply and preventing scalding or overheating.

What is the purpose of the Ariston thermal safety device (part 570970) with a 16-10°C rating?

The Ariston thermal safety device (part 570970) is a high-limit thermostat that protects the boiler from overheating. The '16-10°C' rating indicates that the device is designed to open (break the circuit) at a temperature of 100°C, with a differential of 16°C (meaning it resets at 84°C). When the water temperature in the heat exchanger reaches 100°C, the device interrupts the power supply to the burner or gas valve, shutting down the boiler to prevent boiling, pressure buildup, or damage to components. This is a safety-critical component that must be replaced with an OEM part to ensure correct temperature thresholds and reliable operation.

Are Ariston temperature probes like the 004N and 950600 interchangeable?

No, Ariston temperature probes such as the 004N (part 004N) and the metal probe (part 950600) are not interchangeable. Each probe has a specific resistance-temperature curve and connector type that matches a particular boiler model or series. The 004N is typically used in certain Ariston boilers, while the metal probe 950600 is designed for other models, possibly with different mounting threads or sensing elements. Using the wrong probe can result in incorrect temperature readings, leading to improper burner modulation or safety shutdowns. Always verify the compatibility of the probe with your boiler's model and part number before replacement.

What is the role of the Ariston city contact probe (part 990686) in a boiler system?

The Ariston city contact probe (part 990686) is a sensor that allows the boiler to interface with external control signals, such as those from a district heating system, a remote thermostat, or a building management system. It detects the presence of a voltage or contact closure from an external source and communicates this to the boiler's control board. This enables the boiler to modulate its output based on demand from outside the unit, such as when a central controller requests heat. This probe is commonly used in multi-zone or commercial installations where boilers need to respond to centralized commands.

Can I use Ariston boiler spare parts in non-Ariston boilers?

Ariston boiler spare parts are designed specifically for Ariston boilers and may not be compatible with other brands. Components like ignition modules, thermostats, and probes have unique electrical characteristics, mounting dimensions, and connector types that are matched to Ariston's control systems. Using them in non-Ariston boilers could lead to improper operation, safety hazards, or voiding of warranties. It is recommended to use parts that are certified for your specific boiler brand and model. For Ariston boilers, using genuine Ariston parts ensures correct fit and function.
