Baxi heat pump brings efficient heat to self-build Suffolk property

A renewables specialist in Suffolk has transformed the sustainability credentials of a spacious three-bedroom self-build property in Peasenhall by fitting a new air source heat pump.

The 2,600ft² self-build property, built by owners Jonathan and Emma Hayes, required a heating system capable of improving energy efficiency while being suitable for off-grid applications. Another significant requirement involved curtailing the environmental impact of the property. Jonathan reached out to Renew East, a renewable heat specialist, who recommended Baxi’s HP40 Monobloc Air Source Heat Pump (ASHP).

Approximately a third of the properties in Suffolk, including the luxury self-build, were not connected to the mains gas grid, making it a prime candidate for a renewable heating system. Although Renew East Director, Luke Nicholls, is an experienced heating engineer, he welcomed the opportunity to benefit from the support of Baxi services on his first installation of the new product.

After carrying out complete heat loss calculations on the property, Luke recommended the 11kW Baxi HP40 Monobloc heat pump with a 250l hot water cylinder. This system feeds the underfloor heating, which emits 11kw of heat even at temperatures as low as -5°C. The system control panel has a user-friendly interface that aids the commissioning process by allowing Luke and his team to view the performance of the outside unit from within the property. Simultaneously, Jonathan and Emma have complete control over the temperature in their home through the heat pump’s connection to Baxi’s uSense smart room thermostat.

The Baxi monobloc design aided in the smooth installation process of many standard components such as the mims controller, circulation pump and expansion vessel, housed in the main outdoor unit. 

As part of the company’s support for its heating engineers, Renew East accessed Baxi’s extensive heat pump services and expertise both before and during the project, leading up to its installation. To familiarise themselves with Baxi solutions, the team was encouraged to attend hands-on heat pump training, covering design and application, in addition to the practical elements of the installation and commissioning of the system. Once the installation was complete, they benefitted from the commissioning supervision offered by Baxi’s expert heat pump engineers. They could ensure the solution delivered its intended design performance before handover to the homeowners.
