Making the switch to a heat pump is one of the most significant energy efficiency upgrades you can make to your home. While the benefits are substantial—lower running costs, reduced carbon emissions, and eligibility for government grants—many homeowners feel uncertain about the installation process itself. At CRG Direct, we believe transparency is key, which is why we've created this comprehensive guide to walk you through exactly what to expect from survey to commissioning.
Initial Survey and Assessment: The Foundation of Success
The Site Survey Process
Your heat pump journey begins with a thorough site survey conducted by one of our MCS-accredited engineers. This typically takes 2-3 hours and involves:
- Heat loss calculations: We measure room dimensions, assess insulation levels, and calculate your property's specific heating requirements
- Existing system evaluation: Reviewing your current heating system, radiators, and pipework
- External unit placement: Identifying optimal locations considering noise, airflow, and accessibility
- Internal unit positioning: Planning where your new heating controls and hot water cylinder will be installed
