Project overview

The SAPPHIRE Solo project will explore the provision of smart energy systems in homes that incorporate heat pump technology, battery, and Solar PV. Adopting a system approach, the smart energy system’s key benefit is to enable a switch from gas to electric heating without raising energy bills. This delivers more carbon savings and offers greater economic benefit than installing heat pumps on their own.

The project aims to understand the feasibility of aggregated installations for optimised management and generation of grid services revenues which help fund the equipment, to provide a further benefit to the consumer. The project also includes developing an approach to work with local gas service engineers, boosting install capacity and providing a key channel to market at scale.

This project was supported during phase 1 of Heat Pump Ready to prepare a feasibility study. The final report is published below:
