the competition: irrigation sprinklers
Irrigation sprinklers vs. SprayHose for protecting a home
Today, the most commonly used devices to protect homes from wildfires are irrigation sprinklers.They are expensive and take a long time to deploy.
The SprayHose is much lower in cost and deploys more quickly.
Unlike sprinklers, the SprayHose has no moving parts which can be damaged during deployment.
The spray nozzle can send water straight up.
Sprinklers cannot do that.
Because sprinkler array is always moving, it will let more embers get by.
THE SPRAY NOZZLES PRESENT A CONTINUOUS WALL OF WATER TO PASS FEWER EMBERS. WALLS WILL BE KEPT MORE WET.
