Intatec ZEROGUARD Anti-Freeze Valve Protector for Inta Zero Heat Pump Valves
The Intatec ZEROGUARD is a purpose-designed two-part protector for the Inta Zero anti-freeze valve range, recommended by Intatec for use on all external ASHP installations where a Zero valve has been fitted and insulated. It protects the valve's anti-vacuum vent from dust, debris, water ingress, and mechanical interference — while keeping the vent itself clear and accessible — throughout the operational life of the installation.
Intatec explicitly recommend fitting the ZEROGUARD whenever a Zero anti-freeze valve is insulated, and specify that it should be inspected as part of the system's annual service. It is also included as standard in the Intatec Zero Professional Installer Pack range and the Barco Zero Heat Pump Installer Packs.
How the ZEROGUARD Works
The ZEROGUARD consists of two parts: a lower sleeve and a covered vent cap. The lower sleeve slots over the body of the Inta Zero anti-freeze valve and is sealed into the insulation jacket using Primary Pro Bond & Seal, integrating it cleanly into the insulated assembly and preventing water from tracking down into the insulation or valve body. The covered vent cap is then push-fitted over the top of the lower sleeve using a secure O-ring seal, enclosing and protecting the valve's anti-vacuum vent from external contamination.
The anti-vacuum vent on the Inta Zero valve must remain unobstructed at all times to allow the valve to function correctly — if the vent is blocked by debris or water, the valve may not discharge properly when the water temperature reaches 3°C. The ZEROGUARD's covered vent design keeps debris, insects, and water spray away from the vent opening, while the push-fit O-ring cap can be removed quickly by hand for annual inspection and cleaning without any tools.
Key Features
Anti-vacuum vent protection
Shields the valve's anti-vacuum vent from dust, debris, insects, and water ingress without blocking airflow.
Two-part push-fit assembly
Lower sleeve seals permanently into the insulation; covered vent cap removes by hand for easy annual inspection.
Insulation integration
Sealed into the insulation jacket with Bond & Seal for a clean, weatherproof finish that meets Part L requirements.
Intatec-recommended accessory
Specified by Intatec for all insulated Zero valve installations. Included as standard in the Intatec Professional Installer Pack range.
Mechanical protection
Provides physical protection to the valve's operating element and anti-vacuum system from accidental impact on site and in service.
Compatible with full Zero range
Fits all Inta Zero anti-freeze valve SKUs: ZERO28, ZERO35, ZERO001, ZERO114, ZERO1SW, and ZERO14SW.

Frequently Asked Questions
Why does the anti-vacuum vent need to be kept clear?
The Inta Zero valve's anti-vacuum vent allows the valve to discharge water correctly when the circuit water temperature drops to 3°C. If the vent becomes blocked by debris, insect nesting, or water ingress, the valve may be prevented from opening or may not discharge at the correct rate — potentially allowing the heat pump circuit to freeze. The ZEROGUARD protects the vent from blockage while maintaining the airflow the vent requires to function.
Is the ZEROGUARD mandatory or just recommended?
Intatec recommend the ZEROGUARD for all insulated Zero valve installations and include it as standard in their Professional Installer Pack range. While it is described as a recommendation rather than a hard requirement, fitting it is considered best practice and aligns with Intatec's guidance. Given that the anti-vacuum vent must be kept clear at all times, the ZEROGUARD is the most practical way to ensure this on an external installation subject to weathering, debris, and wildlife.
Can the ZEROGUARD be removed for servicing without disturbing the insulation?
Yes. The covered vent cap is a push-fit O-ring seal and can be removed by hand without tools, giving access to the anti-vacuum vent for inspection and cleaning at the annual service. The lower sleeve remains sealed into the insulation and does not need to be removed for routine inspection. Only the vent cap needs to come off, and it refits by pushing it back onto the lower sleeve.
How many ZEROGUARDs do I need for a standard heat pump installation?
A standard external ASHP installation has two anti-freeze valves — one on the flow pipe and one on the return pipe. You therefore need two ZEROGUARDs. The Barco Zero Heat Pump Installer Packs (28mm and 1-1/4" swivel) both include two ZEROGUARDs as part of the pack. If you are purchasing Zero valves individually, order one ZEROGUARD per valve.
Does the ZEROGUARD need to be sealed with Bond & Seal?
The lower sleeve of the ZEROGUARD is sealed into the insulation jacket using Primary Pro Bond & Seal (AS001) when the valve insulation is fitted, to create a weatherproof seal around the base of the protector. The vent cap itself does not require sealant — it relies on the push-fit O-ring for its seal. Bond & Seal 290ml (AS001) is included in both Barco Zero Installer Packs and is also available separately.
