A spreadsheet based questionnaire to be completed by an applicant where an installation uses external piping. Input answers will be assessed to let you know if Ofgem will accept external piping as being ‘properly insulated’ and, if it is, whether the associated heat loss can be disregarded. It also contains Ofgem’s heat loss calculator spreadsheet for instances where it may be more appropriate to estimate heat loss from external piping than to install meters.
Please see the Heat Loss Assessment Guidance document to help you complete the assessment.
