What is a Heat Loss Survey?
A heat loss survey is a detailed assessment of how your property retains and loses heat. Using professional equipment and industry-standard calculations, we measure your home’s thermal performance to determine exact heating requirements.
This technical survey is crucial for accurately sizing heating systems, particularly for heat pump installations. It provides the data needed to ensure your new system is powerful enough to heat your home efficiently while avoiding unnecessary costs from oversizing.
Our Survey Process
External Assessment
We begin with a thorough external inspection of your property, including measuring wall areas, identifying construction types, and assessing windows and doors. We’ll check your roof condition and note any obvious heat loss points around your home.
Internal Assessment
Room-by-room heat loss calculation, factoring in insulation levels, window sizes, building materials, and airtightness. Proper calculations help determine the required flow temperature and emitter sizing, ensuring optimal performance and energy efficiency.
Data Analysis
Using industry-standard calculations, we process your survey data to determine:
