Anti Freeze in Forced Hot Water System

MooseRiverMan · 08-03-2009, 03:59 PM

I am getting mixed comments on the use of non toxic anti freeze in a forced hot water heating system.

I have had it in my existing system for many years (20+) and while it does affect the valves etc somewhat I thought it was worth the comfort of knowing the pipes wouldn't freeze when the power went out. Now I'm planning to put in a new boiler with an indirect hot water tank (the old boiler being a tankless hot water system) and need to figure out whether to continue with the antifreeze.

Any thoughts??
