In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
The pipes in one zone of my hot water heater system are frozen. It's a very long run from the boiler to the room where the baseboards are and many of the pipes are hidden in walls and under eaves of the roof. When this happened the last time a few years ago, I bought an amazing device called Thermguard www.bearmountaindesign.com/ and it solved the problem by triggering hot water through the pipes every few minutes, thus preventing the water from freezing in any potentially exposed vulnerable areas. However, I forgot the change the batteries on the Thermguard and now I have the frozen pipes. I have plumbers here who are trying to heat the pipes using some sort of HOT SPOT to send electric current through the pipes to heat them and see if it will melt the ice, but so far, no luck (many hours). It's difficult to identify where the ice has formed and the pipes run a long way through the walls of the house from the boiler.
1) Any other ideas?
2) Any creative solutions for how to prevent this in the future? I have read about using a Gycol mixture, but I am not sure who would know how to do this or the correct dilution?
