Which type of boiler needs a temperature gauge?

The correct choice indicates that both steam and water boilers require a temperature gauge to operate effectively and safely. Temperature gauges play a crucial role in monitoring the operating conditions of these systems.

For steam boilers, the temperature gauge is vital for ensuring the steam produced does not exceed safe operating limits. High temperatures can lead to excessive pressure, making the system unsafe and potentially leading to catastrophic failures.

Water boilers, on the other hand, require temperature monitoring to maintain efficient heating and to prevent overheating. By keeping track of the water temperature, a water boiler can maintain the optimal thermal efficiency and prevent issues such as scaling or system damage due to excessive heat.

Both types of boilers utilize temperature gauges to provide operators with critical information regarding their current state, ensuring both efficiency and safety in their operation. The dependence on this monitoring instrument underscores the importance of temperature management in both steam and water systems.
