Fernox TF1 Antifreeze Valve

*This product comes as a single unit*

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.

A high-performance antifreeze valve specifically designed to protect water-based Heat Pump systems.

Manufactured from brass for robust, durable and long-term operation.

Industry-leading KV values for high performance.

Automatic operation when the circuit temperature reaches below 3° C.

Supplied with both Male and Female BSP connections for ease of installation on the flow and return pipes.

Available in different sizes to ensure full compatibility for multiple applications.

The system should have 2 valves per system.

IMPORTANT - When connecting a new heat pump directly to a radiator/underfloor domestic heating circuit, it is advisable to ensure the heating circuit is cleaned and flushed to remove all sludge and corrosion debris before the new heat pump is installed.

It is important that all heating systems are flushed and cleaned, and the correct inhibitors are added to the system. We can recommend suitable inhibitors depending on your system.
