Case Study

Case study: Rivendell ASHP cost and carbon savings for period building 

The transition towards renewable energy sources is gaining momentum, and more and more homeowners are seeking environmentally friendly solutions for their energy needs. In this case study, isoenergy helped the new owners of a period Cotswold stone house to replace their oil boiler system with a more sustainable solution. 

In this case study, isoenergy replaced an oil boiler system in a period Cotswold stone house with a more sustainable solution, resulting in significant cost savings and reduced carbon footprint.

Property type: Residential 
Technologies installed: Heat pump  
Collector type: Air 
Size (kW): N/A 
New/retrofit: Retrofit   

The recommended solution:  After thoroughly assessing the property, isoenergy recommended installing an air source heat pump system. This solution involves the installation of an outdoor unit that absorbs heat from the air and a compressor unit that transfers the heat into the property’s heating system. This technology is highly efficient and cost-effective, with a significantly lower carbon footprint than traditional heating systems. 

Reduction of carbon emissions by 80%

isoenergy worked closely with the owners to design a customised air source heat pump system most suitable for their property’s unique requirements. They ensured the installation was completed to the highest standards and provided ongoing support and maintenance services to ensure the system’s long-term performance. 

Key features:   

  • 16kW CTC air source heat pump 
  • 300 litre hot water cylinder 
  • 200 litre water buffer tank 

Outcome:  The air source heat pump at Rivendell is a prime example of how a period building can be comfortably and efficiently heated by an air source heat pump. The client has significantly reduced their long-term running costs, and carbon emissions reduction is over 80%. The owners now have a sustainable heating system that is reliable, efficient, and cost-effective. They can now enjoy a comfortable living environment without worrying about environmental impact.
