GRUNDFOS Circulator Pump COMFORT 15-14 BXA PM 1x230V G1 DACH

COMFORT 15-14 BX TA The COMFORT TA is an efficient circulating pump designed for hot water circulation in residential buildings with a dedicated return pipe. It is compatible with all types of hot water tanks, instantaneous water heaters, solar, or heat pump systems, regardless of whether the system has mixing or regulating valves installed. The pump features a compact casing and a permanent magnet motor with an integrated control unit. The spherical rotor, equipped with an impeller, ensures optimal functionality, supported by a robust single-bearing system. The potable water-approved brass pump housing guarantees both safety and reliability. The COMFORT TA also incorporates a built-in temperature sensor for maintaining water temperature. The user-friendly interface features LEDs and push buttons on the control panel. This provides an intuitive way to display and adjust operating times and control modes, ensuring a comfortable and energy-efficient experience in the residential area. The COMFORT TA offers three control modes: AUTOADAPT, Temperature, and Continuous 24/7. With AUTOADAPT control mode, the pump quickly learns usage patterns throughout the day, ensuring hot water is available only when needed, via an external sensor on the supply pipe. The pump can therefore distinguish between morning, evening, weekdays, weekends, and inactive periods such as holidays, saving energy and water by operating the pump only when required. After 24 hours of no hot water usage, the pump automatically enters holiday mode and resumes operation when there is a demand for hot water. For the first two weeks after installation, the pump frequently starts based on temperature control to ensure immediate comfort until the usage pattern is learned. The pump provides immediate comfort whenever it detects a demand for hot water, regardless of the usage pattern. Once a week, the pump runs a 15-minute disinfection (anti-legionella) cycle. The water heater needs to enable this feature once a week. The temperature control mode integrates both the external and internal sensors for a more accurate measurement of the water temperature and activates the pump when the water temperature falls below a specific level. The on/off temperatures are automatically adjusted based on the maximum measured temperature in the system. The maximum temperature of the system is constantly measured, enabling dynamic adjustment of the on/off temperatures. This mode also includes an automatic holiday mode for enhanced energy efficiency, making it ideal for holiday homes. Continuous 24/7 control mode The pump operates continuously 24 hours a day. The product offers: {_BL_}Q-H performance designed for single and multi-family houses, depending on the required operating point to adapt to heat loss in a specific pipe layout. {_BL_}67% reduction in heat loss compared to a continuously running pump. {_BL_}Low energy consumption and silent operation. {_BL_}Compliance with pipe manufacturers' flow velocity limits, including DN 15, DN 20 PEX, copper, and others. {_BL_}Potable water approval, ensured by the brass pump housing, stainless steel rotor, and composite impeller. {_BL_}A design that makes it easy to clean scale and foreign deposits by removing the pump head, making the product meet unlimited water hardness requirements. {_BL_}Dry-running protection to prevent failures if the system runs out of water. {_BL_}Multiple installation positions, including with the pump head pointing downwards. {_BL_}A pump head that fits brass pump housings of old and new pumps of the same design, even from different pump manufacturers (such as WILO, VORTEX, LOWARA, DAB, and others). {_BL_}Easy electrical installation, provided by a pre-mounted mains plug with a 1.5 m cable and a double-insulated protection design that eliminates the need for an earth cable. {_BL_}Insulating shells to reduce heat loss. {_BL_}Check and shut-off valves included in the BX variant, reducing installation costs. {_BL_}An optional drain flange, which provides an easy way to vent or drain the system without the need for a permanently installed additional drain valve. {_BL_}Optional connections for pipe connections in different sizes and types. {_BL_}Optional check and shut-off valves are available.
