Water Mist VS Sprinkler Systems

Which suppression system best suits my project?

We often get asked by our clients which is better a water mist or a traditional sprinkler system? At QSD we specialise in the design, installation and maintenance of both traditional fire sprinkler systems and water mist systems for domestic and residential properties so for a non biased opinion read on.

Fire suppression systems – water mist and sprinkler systems work in the same way activating when there is a fire to wet the surface of the fuel and the surrounding area to cool and supress the fire. Only the sprinkler head or mist nozzle situated in the area of the fire will release water meaning in most cases only one or two sprinkler heads are required to supress a fire.

Both water mist and sprinkler systems have fixed pipe work and fixed concealed heads. Water mist systems use less discharge less water than sprinkler systems which may result in less water damage to property. This is because mist systems are pressurised. In properties with low water flow a mist system may be more appropriate as for a traditional sprinkler system to work a water tank will be required to ensure adequate water low.

Environmental Impact and Efficiency

Water Use and Conservation

Water mist systems are renowned for their efficient use of water. By utilising fine mist, these systems consume significantly less water than traditional sprinklers, making them ideal for environmentally conscious businesses. This efficiency not only helps in conserving water resources but also reduces the operational costs associated with water usage and drainage.

Energy Requirements

Despite their high efficiency in water usage, water mist systems often require more energy due to the need for pumps that pressurise the water. Businesses considering these systems should balance the water savings against potential increases in energy use.

System Suitability and Applications

High-Risk Areas

Water mist systems excel in environments where electronics and valuable artworks are present, as the fine mist causes minimal damage while effectively suppressing fires. This makes them ideal for use in museums, data centres, and server rooms where water damage from traditional sprinklers could be catastrophic.

Residential and Commercial Use

For residential properties, traditional sprinklers are often sufficient and more cost-effective, especially in areas where water supply is not a concern. However, for businesses operating in high-rise buildings or areas with limited water supply, water mist systems may offer a practical solution.

Safety and Maintenance

Regular Maintenance

Both systems require regular maintenance to ensure optimal performance. This includes annual inspections and servicing to check for any clogs, leaks, or mechanical failures. Ensuring these systems are well-maintained is crucial for their effectiveness in emergency situations.

Legislation Compliance

It’s essential to consider local fire safety regulations when choosing between water mist and traditional sprinkler systems. Some jurisdictions may have specific requirements or preferences for certain types of fire suppression systems.

 

 

 

We recommend that both water mist and sprinkler systems are serviced annually to ensure the system is in working order and would be effective in the event of a fire.
