What Are Anti-Freeze Valves for Air Source Heat Pumps?

Anti-Freeze Valves are essential accessories for protecting Air Source Heat Pump (ASHP) pipework and equipment from damage caused by frozen water. These valves provide a superior alternative to traditional anti-freeze additives, ensuring your Air Source Heat Pump system runs efficiently throughout the year. At Heat Pump Accessories, we offer a wide range of Anti-Freeze Valves that are ideal for Monobloc Air Source Heat Pumps and Hydro Split Air Source Heat Pumps.

Key Features of Anti-Freeze Valves

1. Final Protection for Your Heat Pump System Anti-Freeze Valves serve as a crucial last line of defense, providing additional protection to your Air Source Heat Pump system. Their activation is rare and typically requires extreme conditions:

• A prolonged power failure that prevents built-in Air Source Heat Pump protection from functioning.
• Extended periods of cold weather that last longer than just overnight freezes.
• Exposed pipework installation.
• Unnoticed power failure that goes unaddressed.

2. Improved Performance and Environmental Benefits Using an Anti-Freeze Valve from Heat Pump Accessories means there is no need for glycol, which enhances the performance of your Air Source Heat Pump. Additionally, eliminating glycol offers significant environmental benefits, as it reduces the system's carbon footprint while maintaining optimal efficiency.

3. Lower Maintenance Costs When it's time for maintenance, Anti-Freeze Valves ensure only water is used in the primary pipework, reducing the need for glycol-based solutions. This can significantly lower your maintenance costs by streamlining maintenance routines and reducing the frequency of complex servicing.

Choosing the Right Anti-Freeze Valve for Your System

Choosing the right Anti-Freeze Valve is crucial for protecting your Air Source Heat Pump system. At Heat Pump Accessories, we offer a full range of high-quality Anti-Freeze Valves, each manufactured in Italy and rigorously tested for reliability and performance. Our valves are designed to ensure your system operates at peak efficiency, providing long-lasting protection.

Installation Tips for Anti-Freeze Valves

• Anti-Freeze Valves should be installed at the lowest point on both the flow and return connections in the external pipework, close to the Air Source Heat Pump equipment.
• If insulation is installed, it should be omitted at the vacuum valve (top) and discharge valve (bottom).
• Insulation around the valve should match the surrounding pipework insulation but should not exceed it.
• For optimal performance, install the Anti-Freeze Valve at least 150mm above the ground to allow proper discharge and prevent snow or debris accumulation.
