Fernox 62665 Tf1 Heat Pump Antifreeze Valve 1.25" Male Thread

The Fernox TF1 Antifreeze Valve is specifically designed to protect water-based air and ground source Heat Pump heating systems. In cold weather when temperatures drop, systems that are not treated with a glycol-based fluid can freeze within the heat pump circuit potentially causing harmful and costly damage to vulnerable heat pump components and system pipework; eventually causing premature breakdown and repair. The Fernox TF1 Antifreeze Valve is an essential, simple to install component developed to prevent frozen systems by detecting when the fluid in the circuit is close to freezing point i.e., when the circuit temperature reaches below 3° C. The TF1 Antifreeze Valve will automatically open and release system water, preventing ice from forming within the Heat Pump system and safeguarding the operation of the system.
