Using a compliant pack such as this Calmag Part L pack ensures the installation meets both regulatory requirements and manufacturer conditions of warranty, protecting the engineer from liability and the homeowner from invalid warranty claims.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n  \u003cdiv class=\"cm-faq-item\"\u003e\n    \u003ch3\u003eIs this pack sufficient for a large system?\u003c\/h3\u003e\n    \u003cp\u003eThe inhibitor and cleanser concentrates are each sized for a domestic system of up to 10 radiators or 100 litres of system water volume. For larger systems (more than 10 radiators or commercial installations), additional concentrates should be purchased to achieve the correct dosage rate. The filter and scale inhibitor are standard 22mm and 15mm fittings compatible with all standard domestic heating systems.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"cm-faq-item\"\u003e\n    \u003ch3\u003eDoes the filling loop need to be permanently installed?\u003c\/h3\u003e\n    \u003cp\u003eNo — the filling loop is a temporary connection used to pressurise the sealed heating system. It is connected to the cold mains, used to fill or re-pressurise the system, and then disconnected and removed after use to prevent any backflow risk.

No power or chemicals are required — the device uses a sacrificial electrolytic element that reacts with calcium ions to inhibit their crystallisation into hard scale on heat exchanger surfaces.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"cm-infobox\"\u003e\n\u003cstrong\u003e⚠️ Note:\u003c\/strong\u003e Pack designed for systems up to 10 radiators \/ 100L.
