The Baxi Assure HP55-6-1-PHMB, identified by GC number 7898259, represents a component of Baxi's renewable heating portfolio. Introduced in 2019, this heat pump is designed to provide efficient heating for residential properties. Per manufacturer documentation, the appliance achieves an ErP rating of A+++ at both 35°C and 55°C flow temperatures. This indicates a high level of seasonal efficiency, contributing to reduced operational costs for the end-user.
Sound emissions are a key consideration for heat pump installations, particularly in densely populated areas of the UK. The Assure HP55-6-1-PHMB has a sound power level (LwA) of 48 dB. This metric is important for assessing compliance with local planning regulations and Permitted Development criteria under MCS 020, which specifies minimum distances from neighbouring properties to mitigate noise impact. Installers should consult the full technical datasheet for specific guidance on siting.
Due to the 'low' confidence in the extracted data, specific details regarding the heat pump's nominal capacity, refrigerant type, and physical dimensions are not comprehensively available in the provided information. Engineers are advised to consult the official Baxi technical manual or product datasheet for the Assure HP55-6-1-PHMB to obtain precise specifications for system design, installation, and servicing. This ensures accurate sizing for a property's heat loss, correct hydraulic integration, and adherence to F-Gas regulations if applicable. The absence of detailed fault codes in the current data necessitates reliance on manufacturer-supplied diagnostic information during servicing.
