The Baxi HP60_UK_ERP_Label_HP60-4-1-PHMB, identified by the model number HP60-4-1-PHMB, is a heat pump model introduced by Baxi in 2019. Per manufacturer documentation, this appliance is rated with a nominal heating capacity of 5 kW. This output capacity positions it for integration into various domestic heating systems, particularly those in smaller to medium-sized UK properties, depending on the property's heat loss characteristics.
Efficiency is a key performance metric for heat pumps. The HP60-4-1-PHMB achieves an ErP rating of A+++ for both 35°C and 55°C flow temperatures. This indicates a high level of seasonal efficiency across different operating conditions, which is a significant factor for both energy consumption and compliance with current UK building regulations. The ErP label specifically highlights these efficiency classes, suggesting robust performance in standard heating scenarios.
A practical consideration for heat pump installations, especially in residential areas, is sound emission. The Baxi HP60-4-1-PHMB reports a sound pressure level of 48 dB at 1 metre. This metric provides an indication of the operational noise from the outdoor unit, which is relevant for planning permission and neighbour considerations under MCS 020 guidelines, although specific MCS certification details for this model are not available.
While specific details regarding refrigerant type, GWP, and charge are not explicitly provided in the available data, the unit's design is intended for UK domestic heating. For engineers, understanding the full technical specifications and installation requirements is crucial. Homeowners should consult with a qualified MCS-certified installer to assess system compatibility and ensure optimal performance for their property. The information presented here is based on available public data, and engineers are advised to consult the latest Baxi technical documentation for comprehensive details.
