I don't know of any products ________________________________________ From: [email protected] [[email protected]] On Behalf Of Nicky Marshall [[email protected]] Sent: Thursday, June 13, 2013 5:02 AM To: [email protected] Subject: Freeze prevention
Is anybody aware of approved systems for freeze prevention of sprinkler pipework that involves circulating water within pipework? We are aware of dry systems, anti-freeze systems, heat tracing. A dry system requires additional water due to area increase - a tank would be needed. Anti freeze has not got very good press lately and approved products are expensive. Heat tracing does not seem like a very energy efficient system. There are circulating systems for domestic applications and internet searches show several patents for such systems for sprinklers, but I cannot find actual products.
