Abstract

Highlights
•Energy use for DHW accounts from 16% to 50% of total heat requirement.
•Method to estimate mean hourly and daily profile of DHW from total heating readings.
•Method gives good results when DHW share in total heating demand is minimum 50%.
•Better understanding of users’ practice related to DHW and space heating is crucial.
