EvidenceHeating Sources and How to Use Them
Check the original technical, safety and public-program documents behind a heating question, including their date, scope and equipment applicability.
Use the document that answers the question
A heat-pump overview explains concepts; a model manual explains a product; a site assessment describes the actual house. They are different kinds of evidence. Compare the full model and configuration before using a specification. Confirm operative program rules before counting an incentive as approved funding. Do not turn an online summary into a safety finding.
