How safe are the hoses?
The hose is custom manufactured and is more than rugged enough for the application. They are designed for an operating pressure of 150psi and have been burst tested to 600psi while the Heat Assault system generates less than 40psi. In more than a decade of experience with hundreds of systems in the field we have never had a bursting failure of these hoses. All of the connections at the end of the hoses are self sealing so they will leak only a few teaspoons of HTF when they come apart. The HTF is a Propylene Glycol/ Water solution (Plumber’s Antifreeze) which is environmentally safe.
