It is designed for domestic storage tank and tankless heater installations where hot water return lines benefit from demand-based operation rather than continuous running.\u003c\/p\u003e\r\n\u003cp\u003eRated flow reaches 7.5 L\/Min against a maximum head of 1.4 m, drawn from a 7 W motor at 0.07 A on a 1 x 240 V supply, matching the hydraulic output of the fixed-speed Comfort range while adding selectable operating logic. Three modes are available: AUTOADAPT for automatic demand-based adjustment, Temperature Control for return-line temperature triggering, and Continuous Operation for round-the-clock running when preferred.\u003c\/p\u003e\r\n\u003cp\u003eIn AUTOADAPT mode the pump reads system behaviour and adjusts its own duty cycle rather than running at a fixed rate regardless of demand, while Temperature Control mode limits operation to periods when the return line has actually cooled. A spherical rotor and single-bearing arrangement keep internal friction low across whichever mode is selected.\u003c\/p\u003e\r\n\u003cp\u003eThe drinking-water approved brass housing handles liquid temperatures up to 95°C and system pressures to 10 bar, with the pump head removable for cleaning in hard water areas. At 80 mm port-to-port with an IP44 enclosure and included insulating shell, it fits tight installation spaces while giving the installer control over how the pump actually runs.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eThree selectable operating modes: AUTOADAPT, Temperature Control, and Continuous Operation\u003c\/li\u003e\r\n\u003cli\u003eSpherical rotor geometry with a single-bearing support system reduces internal friction\u003c\/li\u003e\r\n\u003cli\u003eComposite impeller construction resists corrosion in domestic hot water applications\u003c\/li\u003e\r\n\u003cli\u003eRemovable pump head permits access for cleaning and descaling without draining the system\u003c\/li\u003e\r\n\u003cli\u003eBrass pump housing with dezincification-resistant properties and drinking-water approval\u003c\/li\u003e\r\n\u003cli\u003eInsulating shell fitted as standard to reduce heat loss from the pump body\u003c\/li\u003e\r\n\u003cli\u003eCompact 80 mm port-to-port body dimension for installations with space constraints\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50978282012919,"sku":"99164487","price":522.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-comfort-15-14-b-ta-brass-autoadapt-circulator-pump-for-domestic-hot-water.png?v=1785223203","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-comfort-15-14-b-ta-brass-autoadapt-circulator-pump-for-domestic-hot-water","provider":"Foundation Pumps","version":"1.0","type":"link"}
