Extended warranty up to 5 years is available if already agreed through your Baxi Specification Manager. Product warranty must be registered directly through Baxi Project Hub within 30 days of commissioning if commissioned by a Baxi Heat Pump Installer. For other installations, a Baxi commissioning visit must be booked via baxi.co.uk/projecthub. The Baxi Assure HP50 ASHP and the magnetic filter must be serviced annually within 60 days of the anniversary of the commissioning date. The warranty will revert to 2 years if the magnetic filter is not fitted at installation or is removed.
The Baxi Assure HP50 is identified as a monobloc air source heat pump, part of the Baxi Assure product family. As a monobloc unit, the primary refrigeration circuit is contained within the outdoor unit, simplifying installation by eliminating the need for F-Gas certified installers to handle refrigerant on site. This design typically involves connecting the unit directly to the property's heating system via water pipes.
Regarding warranty, the Baxi Assure HP50 comes with a standard 2-year warranty. An extended warranty of up to 5 years is available, subject to specific conditions. These conditions include prior agreement through a Baxi Specification Manager and registration via the Baxi Project Hub within 30 days of commissioning if installed by a Baxi Heat Pump Installer. For other installations, a Baxi commissioning visit must be booked. Crucially, the extended warranty is contingent on annual servicing of both the HP50 ASHP and its magnetic filter within 60 days of the commissioning anniversary. Failure to fit the magnetic filter at installation or its subsequent removal will revert the warranty to the standard 2 years. Both parts and labour are covered under these warranty terms, and registration is mandatory.
Operational controls for the HP50 include compatibility with a wired controller. The appliance requires annual servicing, with a recommended service interval of 12 months. Due to the source document being a warranty guide, detailed technical specifications such as nominal capacity, efficiency ratings (COP, SCOP), refrigerant type, sound power levels, and physical dimensions are not provided. Similarly, specific fault codes and their resolutions are not detailed within this documentation. Engineers requiring these specifics should consult the full technical datasheet or installation manual.
