If you are concerned about fire, why not install a fire supression system. They are fairly simple to design and if you are familiar with pex plumbing, they are easy to install. This is a good manual to get you started:
http://www.usfa.fema.gov/downloads/pdf/publications/fa-155.pdfI have been looking into fire supression because our county is requiring them on all major subdivision plans that are not located within designated fire districts. A fire supression system helps to keep your family safe, can lower your home owner's insurance, and is a very good idea if you are more than 10 minutes from a fire station. And unlike as Hollywood portrays, a fire sprinkler system doesn't come on as a whole, each sprinkler is triggered by heat and then once the fire is out, the owner turns off the water system. On average a sprinkler system only uses about 350 gallons of water to extinguish a fire, whereas a fire truck on average will put down almost 3,000 gallons to extinguish a fire which can lead to a lot more cleanup after the fire. If I were to build a new house, I would definately look into a fire sprinkler system.
