The V4073A Valve has been designed to control the flow of water in domestic central heating systems, where both radiator and hot water cylinder circuits are pumped. It is typically suited for small to medium sized installations
Exposing external pipework or unoccupied properties to freezing temperatures risks burst pipes and system failure. Fernox ALPHI-11 offers dual protection: preventing water freezing and guarding metal surfaces against oxidation and scale. Designed for modern renewable systems like air-source heat pumps, it safeguards heat exchangers, circuits, and underfloor heating without compromising efficiency or seals.
Scalemaster Electrolytic Scale Inhibitor for whole house protection using proven patented technology it is also ideal for individual appliances which incorporate stored water. Helps meet Part L of the Building Regulations and achieve cost savings through reduced energy use.
Designed to control a combi boiler or single zone, the ST9100C one-channel time switch supports mains, low voltage, or potential-free switching of heating loads. It offers up to three on/off cycles per day and can be programmed differently each day, with optional 5/2 or single-day setups. The Line of Text (LoT) display provides clear instructions at all times, ensuring straightforward installation and use.
