Grundfos Circulation Pump COMFORT 15-14 BX T DACH

COMFORT 15-14 BX T COMFORT T is an efficient circulator pump designed for domestic hot water recirculation in residential buildings with a dedicated return line. The pumps are compatible with all types of hot water tanks, instantaneous systems, solar and heat pumps, regardless of whether mixing or balancing valves are installed in the system. The pump features a compact housing and a permanent magnet with an integrated control unit. The spherical rotor with impeller ensures optimal function, supported by a robust single-ball bearing system. The brass pump housing with drinking water approval guarantees safety and reliability. The COMFORT T also has a built-in temperature sensor to maintain the water temperature. The COMFORT T has a temperature control function which automatically activates the pump when the internal temperature sensor detects that the water temperature drops below a certain value. The control type automatically adjusts the on/off temperature to the maximum temperature measured in the system. The maximum system temperature is measured every 12 hours for 15 minutes to allow dynamic adjustment of the on/off temperature. Product features: {_BL_} Q/H performance designed for single and multi-family homes, depending on the required operating point, to account for heat losses in the respective piping system. {_BL_} Heat losses reduced by 25% compared to a continuously operating pump. {_BL_} Low power consumption and quiet operation. {_BL_} Complies with pipe manufacturers' flow velocity limits, including DN 15, DN 20 PEX, copper, and others. {_BL_} Approved for drinking water; thanks to the brass pump housing, stainless steel rotor, and composite impeller. {_BL_} A design that facilitates the removal of scale and dirt deposits by disassembling the headpiece, allowing the product to meet requirements for unlimited water hardness. {_BL_} Dry-running protection to prevent failure if the system no longer contains water. {_BL_} Various mounting positions, even with the pump head downwards. {_BL_} A pump head that allows for mounting brass pump housings from 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 with pre-assembled mains plug with 1.5 m cable and a double insulation protection design that eliminates the need for an earth cable. {_BL_} Thermal insulation shells to reduce heat losses. {_BL_} Shut-off and check valves included in "BX" versions reduce installation costs. {_BL_} An optional vent flange providing a simple solution for bleeding or draining the system without the need for an additional permanent vent valve. {_BL_} Optional connection fittings for pipe connections of various sizes and types. {_BL_} Optional check valves and shut-off valves are available.
