The Heatline flow sensor kit brings together the parts that most often need attention on the domestic hot water inlet of a Heatline combi boiler: the flow sensor, the impeller (often written impellor), the inlet filter and the flow restrictor. Changing them together restores the boiler’s ability to detect hot water demand and to deliver […]

The Vaillant Pure flow turbine is the hot water flow sensor housing that sits on the cold water inlet of Vaillant Pure combi boilers. Inside it, a small impeller spins whenever a tap is opened, and that movement is what tells the boiler to start producing hot water. When the turbine clogs or wears, the […]

This is a replacement Vaillant turboTEC flow turbine that also covers the Vaillant ecoTEC pro and atmoTEC ranges and the Protherm Pantera, as listed in the title. It is the flow sensor on the cold water inlet that tells these combi boilers when hot water is being drawn. Because one part covers several widely installed […]

Made for the ECA Citius Premix condensing combi boiler, this flow turbine is the part on the cold water inlet that registers hot water demand. A magnetised impeller inside the housing spins when a tap opens, and the boiler’s sensor reads that movement. A tired or scaled turbine leaves the Citius Premix slow to react, […]
