Boiler Pilot Light: Function and Modern Alternatives

Boiler Components

Boiler Pilot Light: Function and Modern Alternatives

The boiler's pilot light is a small constant flame that burns continuously and serves to keep the boiler burner operating. Essentially, the pilot light ignites the main burner whenever it is necessary to heat the water inside the boiler. The pilot light is a very low gas flame,...

Storage Boilers: Efficient Solutions for Hot Water

In Storage Boilers of any type, there is a reserve of sanitary water already at temperature and ready for use. The boiler keeps it hot, thus reducing ignition times and increasing the responsiveness of the domestic hot water system. The "boiler" is a part of the boiler that...

Safety Valves for boilers

Before 1994, boilers were equipped with this type of valve for safety in the water supply circuit. Today, modern storage boilers integrate this valve into the cold water inlet group within the boiler. The function of this valve is to prevent overpressure on the domestic water...

The Condensate Trap of the Boiler

In Condensing Boilers, this component is placed between the primary heat exchanger and the drain line, and it prevents the exhaust gases from discharging into the condensate drain pipe. Table of contents Introduction to Condensing Boilers Alternative Types of Drain Traps...

Sanitary Expansion Tank

The sanitary expansion vessel in storage boilers is essential when there is a significant storage capacity. As the water in the tank heats up, it expands in volume. This component reduces the load on the safety valve of the sanitary system. It is not uncommon to find sanitary...

Boiler Components

Air Pressure Switch: Function and Maintenance Guide

In the low-efficiency type C boiler, the air pressure switch detects the operation of the flue fan (exhaust fan). It consists of two tubes connected to the venturi ports of the extractor, functioning as pressure and vacuum sensors. This safety feature is essential not only for...

How Does a Modulating Circulator Work?

A modulating circulator is a device used in heating systems to regulate the flow of hot water within radiators. It operates by adjusting the water flow to match the actual heat demand of the environment, thereby reducing energy consumption and improving system efficiency. The...

Filling Valve: Essential for Boiler Pressure

Filling Valve: Essential for Boiler Pressure

Usually placed under the boiler, it is a faucet that bridges between the water main and the heating circuit. It is used to charge the system to a pressure of 1.2 bar / 1.5 bar. Use this filling valve to restore the pressure of the heating system. The valve should normally be...

Boiler Components

Boiler Flow Meter: Efficient DHW Control

The boiler flow meter plays a critical role in modern heating systems by detecting the demand for domestic hot water (DHW) with precision. Unlike older models that relied on flow switches, this advanced component improves efficiency, reduces energy waste, and ensures stable...

Heating Safety Valve

This component is essential for the proper functioning of the boiler. The heating safety valve is used to control excess pressure; once a certain limit is reached, it begins to release. It consists of a passage regulated by a membrane pushed by a spring. The spring of the safety...
