Gas boilers parts hydro block feature:
Valves: Hydro blocks contain multiple valves, including a water inlet valve, a water outlet valve, and a gas valve. These valves work together to regulate the flow of water and gas in the boiler.
Sensors: Some hydro blocks include sensors that detect the water temperature and pressure. These sensors help to control the boiler's performance and prevent overheating or overpressure.
Overall, hydro blocks play an important role in regulating the flow of water and gas in gas boilers, ensuring that they operate efficiently and safely.
