  [Participants' self-reported comfort ranges differed drastically in some cases, with a maximum range of 10°C and a minimum range of 2°C. Quote: "... traditional TRVs — as well as smart TRVs set in the way we asked participants to set them — may have reduced our ability to pre-heat homes as much as we aimed to." Quote: "We noted that a lot of participants kept doors to adjoining rooms closed during events. This prevented airflow and may have amplified the effect of different thermal properties of the building fabric throughout their home, as warmer areas performed better and cooler areas did not benefit from warm airflow. Homes with greater variation in their fabric energy efficiency would increase the potential effect." Quote: "HeatFlex events consisted of two different windows, each usually lasting two hours. Pre-heating window: we changed the customer's smart thermostat setpoint to the maximum acceptable temperature. Flexibility window: we changed the customer's smart thermostat to the minimum acceptable temperature." Quote: "This could potentially be developed further into a personalised intervention whereby participants can provide the extent of discomfort they are happy with given a certain expected financial return (similar to risk ratings on financial investments)."]
