Boiler Replacement & Heat Pump Installation for Stillwaters House, Avington Park Estate 

At LR Mechanical, we specialise in upgrading heating systems to improve efficiency, reduce costs, and deliver lasting performance for both commercial and high-end residential properties.
 
Our recent project at Stillwaters House, a luxury holiday home in the Avington Park estate, shows just how much of a difference modern solutions can make without compromising comfort or luxury.
 

Tackling Rising Energy Bills at Stillwaters House 

When the client approached us, the property was being heated by two outdated electric boilers. Their monthly heating bills soared to over £2,000 and the system was unable to support the amenities at the luxury holiday home, including the outdoor sauna that could not be used reliably.
 
Our brief was to design and install a new system that reduced costs and, more importantly, improved reliability and future-proofed the property for long-term performance.
 

Replacing Inefficient Boilers with Modern Heat Pumps 

To resolve the issues the client wanted us to tackle, we carried out a full system replacement. We removed the two electric boilers and performed high-efficiency heat pump installation. The project, completed in just two weeks, included:
 
  • Two 12 kW heat pumps positioned discreetly outside the property
  • Three 200-litre hot water cylinders for a reliable hot water supply
  • Full pipework and system upgrades to connect the new installation
  • Safe removal and decommissioning of the outdated boilers
 
Since the project was fully MCS-certified, the client was also able to get government funding to help cover some of the costs. As experienced commercial heating engineers, we ensured the system delivered both efficiency and compliance.
 

Key Features of the New Heating System 

The new system includes many new features such as:
  • Outdoor installation of two advanced heat pumps for efficiency and low noise
  • Three hot water cylinders to manage the high demand of the property
  • Hybrid-ready design, allowing flexibility for future upgrades
  • All-new pipework and connections for reliability and safety
 

Immediate Cost Savings and Performance Gains 

The benefits of the new system were clear straight away:
  • Heating bills reduced from £2,000+ to £500-£800 per month
  • The outdoor sauna, previously unusable, is now fully operational
  • Enhanced comfort and consistent heating throughout the property
  • Long-term energy savings and reduced environmental impact
 

Aftercare and Ongoing System Support 

Our job doesn’t end with installation. We continue to provide aftercare to ensure long-term performance. From routine servicing to commercial plumbing repairs, our support keeps systems running efficiently and reliably for years to come.
