Contents

• Background

• Heat pump & thermal storage set-up for DSM

• Progress

• Results

• Future work

Backgrounds

• Domestic sector energy consumption for heat and heat

related emissions

• Electricity/heat daily and seasonal demand shift

• Heat pump retrofit challenges

• Non-dispatchable renewables generators limitations and

impact on grid (e.g. wind curtailment )

• Demand side response of heat pump and thermal

storage

Future plans

• Heat pump performance improvement

New working fluids

• System parameter optimisation

• Controller development for : weather compensation and

electricity pricing/load benefits

• End-user satisfaction
