About

HEAT3D  uses an innovative development of the quantitative internal IRT method, combining two new and cheap technologies to provide a low cost handheld instrument offering a quick and highly visual measurement of the heat flux through a building surface in Watts, along with its U value. These measurements can then be used to provide quantitative input to future domestic EPCs (Energy Performance Certificates), to allow before and after measurement of U values during refurbishment of existing buildings to improve insulation, and to check a new building’s performance meets predicted/designed U value expectations.

The research and development behind HEAT3D was part funded by Innovate UK
