Water flow rate = 13.94 litres per nozzle per minute.  Pressurized 300 Litre Water Cylinder, with BurnStop environment-friendly additive, supplies water to the low flow rate, CPVC (Chlorinated Polyvinyl Chloride) pipe network serving 25 Mist Ceiling Heads/Nozzles fixed at pre-determined locations.  See Plans.  Water runtime is 10 minutes, between 2 heads operating simultaneously without any mains water backup.  Installation takes 3 days in total (2 days first fix, plus 1 day second fix and commissioning).

The mains water supply system in Ireland is not reliable.

Cost for the above Notional Water Mist Installation is €7,340.00 (Euros) / £5,676.00 (British Pounds) – plus VAT.  This price is on the basis as a one-off installation in Ireland.  If a number of properties require installation at the same time, then travel costs are dispersed and the individual price per property is significantly reduced.
