Product Information
Full details
The Altecnic iStop Anti-Freeze Valve is designed for system installers and maintenance professionals seeking to protect heat pump systems and other pipework from freeze damage. Its key benefit is automatically draining the system medium when temperatures drop to approximately 3°C, preventing ice formation and subsequent equipment damage. A potential caveat is its specific activation temperature, which may require monitoring in extreme cold environments.

Extended Product Information
FAQs
How does the iStop Anti-Freeze Valve work?
The valve contains a thermostatic element that expands and contracts with temperature changes. When the temperature drops to approximately 3°C, the element triggers the valve to open, allowing system fluid to drain and prevent ice formation.
What type of fluid can be drained by the valve?
The valve is designed to drain the circuit medium, typically water or a water/antifreeze mixture used in heating systems.
Can this valve be used in any heating system?
It is primarily recommended for systems where freeze protection is critical, such as those with heat pumps, or where pipework is exposed to low temperatures. Ensure compatibility with your specific system's pressure and temperature ratings.
Does the valve automatically close when the temperature rises?
Yes, as the temperature increases above the activation point, the thermostatic element retracts, allowing the valve to close.
What is the activation temperature of the valve?
The valve is designed to activate and drain at an average temperature of approximately 3°C.
Do I need to manually reset the valve after it has activated?
No, the valve is automatic. It will close on its own once the temperature rises sufficiently.
Where is the best place to install this valve?
Install it in a location where it can accurately sense the temperature of the system medium and where gravity will assist in draining the fluid effectively away from vulnerable components.
Troubleshooting
Valve fails to open at low temperatures.
Ensure there are no obstructions preventing the valve mechanism from moving. Check that the ambient temperature is indeed reaching the activation threshold of approximately 3°C. Verify proper installation and that the valve is not being held closed by external force.
Valve leaks after closing.
Inspect the valve seat and seal for debris or damage. Tighten union connections if the leak appears to be at the fittings. If the valve itself is faulty, it may require replacement.
System fluid is not draining sufficiently.
Confirm that the drain outlet is not blocked. Ensure the valve is correctly oriented and that the system has enough fluid to drain when the valve opens.
Pros and Cons
Pros
- Prevents costly damage from ice formation in pipework and equipment.
- Automates freeze protection, reducing the need for manual intervention.
- Simple to install with union fittings.
- Enhances the longevity of heat pump systems.
Cons
- Activation temperature is fixed at ~3°C, which might not suit all climates without additional measures.
- Requires the system to be able to safely drain fluid when activated.
- Primarily designed for specific applications like heat pumps.
Setup, Compatibility & Care
Setup:
- Install the Altecnic iStop Anti-Freeze Valve in the desired location within the heating circuit, ensuring it is oriented correctly for drainage.
- Connect the valve to the pipework using the provided union fittings, tightening them to ensure a secure, leak-free seal.
- Ensure the valve's drain outlet is directed to a safe and appropriate disposal point for the system fluid.
Compatibility:
- Suitable for use with standard plumbing and heating systems, particularly those incorporating heat pumps.
- Compatible with various pipe materials that can be fitted with a union connection.
- Check system pressure and temperature ratings against the valve's specifications (refer to manufacturer's technical data).
Care:
- Periodically inspect the valve for any signs of corrosion or damage.
- Ensure the drain outlet is clear of obstructions.
- While the valve is automatic, it's good practice to test its function annually, especially before the onset of colder weather, by simulating a low-temperature condition if possible.
