Protection for pipe freezing

My association is in a mountain resort. Pipe freezing, and the resulting water damage is a big issue and cost for us each year. We are researching inexpensive ways to monitor indoor temperature and get an alert if there is a freeze potential. I would like to share ideas/solutions with others who have similar issues.

We have some kind of light outside the community center that will blink if the furnace goes out or the temp gets too cold, but I don't know anything about it. Ask an electrician.

I'll see if I can find out anything.

I know a homeowner that travels alot and has a couple of water and heat sensors set up in his house using something called x10 devices (do an internet search). They are set up to automatically send an alert on his cell if they are triggered.

I think regular typical security system monitoring company might also offer a similar service. Can be done ... not prohibitively expensive.

Monitoring is a GREAT idea BUT you must realize that if the pipe is installed in a building cavity that is subject to freezing, if you are moniutoring the building interior, the pipe, in this cavity will freeze anyway.

I am a Professional Engineer that investigates causes of frozen pipes for the insurance industry. In addition to maintaining heat at reasonable levels, (I say never below 60 degrees) pipes should be located and insulated in building cavities that are not in contact with exterior temperatures if that can be helped.

For pipes that are installed in exterior walls, in floors over unheated spaces or across attic floors I have patented a pipe insulation design specifically intended to prevent pipes from freezing when located in these areas.

Presently I am working with a company in Smithfield Rhode Island Branch River Plastics (www.branchriver.com) to bring it to market (ask for Greg Kelleher)

I once read that if the unit is going to be vacant during the winter, the homeowner should have the water drained from the house (a plumber can help with this) and then shut it off - since the pipes would have air in them, freezing wouldn't be a factor.
