This paper presents a performance evaluation of two domestic space heating systems that use air source heat pumps (ASHP) to replace conventional boilers with air source heat pumps (ASHP). The storage system consisted of encapsulated PCM spheres in a packed bed with twice the storage capacity over the temperature range of 40 and 65°C achievable with hot water. The simulations predicted a potential CO2 reduction of 23% for the detached dwelling and 20% for the semi-detached dwelling, operating the heat pumps in economy 10 electricity i.e a low tariff at times between 00.00-05.00 and 13.00-16.00; with current grid emission values by successfully offsetting the electrical load to meet the heat demand.
The research presented in this paper is funded by the EPSRC through Grant reference EP/K011847/1, the Interdisciplinary centre for Storage, Transformation and Upgrading of Thermal Energy (i-STUTE) and a Loughborough University funded PhD studentship.
