Question: 1 / 400

When must an electric boiler have more than one safety valve?

If the input is 1000kw or more

If the input is 1100kw or more

An electric boiler must have more than one safety valve if the input is 1100 kW or more because safety regulations and engineering best practices dictate that higher capacity boilers require additional safety measures to prevent dangerous pressure buildups. The safety valve's primary function is to release excess pressure to prevent potential failure or explosions.

When an electric boiler exceeds this threshold of 1100 kW, it is considered to be in a more critical range of operation that poses a greater risk. Therefore, having multiple safety valves ensures redundancy and enhances safety, as it allows for the management of pressure in case one valve fails to operate correctly.

In contrast, thresholds like 1000 kW or lower may permit a single safety valve without compromising safety significantly because lower power levels pose less risk of hazardous pressure conditions. The threshold of 2000 kW is also relevant for certain contexts but is not the minimum requirement for additional safety valves.
