This project is looking at how Compact Combination (CoCo) hybrid heating appliances could kickstart a rapid large-scale uptake of low carbon heating into the stock, providing flexibility, comfort, reliability, and familiarity for occupants.

Compact Combination hybrid heating appliances

Compact Combination (CoCo) hybrids are comparable to a combi boiler in size and heating performance; offering a potential low carbon direct boiler replacement option with minimum disruption. We are researching how such an appliance could kickstart a rapid large-scale uptake of low carbon heating into the stock, providing flexibility, comfort, reliability, and familiarity for occupants. To understand the complex usage of domestic heat we are performing robust analysis of large-scale detailed domestic boiler heat demand data, to ensure CoCo hybrids meet the heat demands of customers (specifically the 20 million combi boiler owners) and deliver significant reductions in carbon emissions.

What we are asking

  • What are the characteristics of combination boiler heat demand?
  • What specification would a CoCo hybrid need to match heat demand and provide lower carbon emissions from domestic heat?
  • What cost and carbon savings could be achieved at household level while maintaining boiler-like heat delivery?
  • What would be the energy system benefits of widespread CoCo hybrid deployment?
