In dwellings connected to district or communal heating schemes occupants are commonly charged based on actual heat consumption, providing a direct link between heat consumption and weekly heating cost. This article investigates how the use of fixed-rate, shared-cost charging without dwelling-level metering affects the heating and controls use in communal network social housing. Living room and radiator temperatures in 50 flats were monitored over a winter heating season and occupants surveyed at monitoring install and removal. The primary stated and observed heating strategy was to leave the heating always on and control through the radiator thermostatic radiator valves. Of people who used timer control, total heating hours reduced with increased frequency of manual intervention. Mean indoor temperatures up to 27.7°C were observed, implying many residents are adapted to higher indoor temperatures. Thus, the current model encourages wasteful behaviour and education on use of controls is key to transitioning residents to charging for actual heat use. Practical application: This article intends to inform the landlords of communal network social housing schemes on the impacts that shared-cost recovery methods of charging for heat has on heating and controls use. This charging method can impact the behaviour of the network occupants resulting in higher heat consumption, overall higher heating costs and subsequently higher carbon emissions from the site if occupants are not adequately trained in how to operate their heating effectively. Where similar charging methods are implemented, the article hopes to inform operators of the potential vulnerabilities of the network occupants to changes in the method of charging for heat.
