Why a detailed site survey matters
As the saying goes, fail to prepare and prepare to fail. Conducting a detailed site survey before starting any installation is essential preparation. This is where potential obstacles or issues can be identified and addressed before the installation begins. It also presents an opportunity to plan things like pipe routes, check that the unit will be on a secure base and not pose a safety risk, and ensure that there is sufficient space for it to begin with.
The site survey is a fundamental first step in delivering a solution that has long-term benefits and performance. Taking specific factors into account from the outset ensures that the installation is as straightforward as possible, with the unique requirements of the homeowner also in mind.
Considering clearances and position
Clearances are essential in making sure the installation is safe and the heat pump itself will operate efficiently by having enough airflow. They also reduce the risk of refrigerant build-up near ignition sources – again, an essential safety requirement – that is an important factor to address for R290 refrigerant.
As well as the safety aspects, the correct position prevents problems associated with noise transfer or vibrations which could also mean the install isn’t compliant. Leaving enough space around the unit is key for servicing and maintenance, and making these vital tasks less challenging.
