The design process aims to create a heating system that satisfies the client's needs. It is crucial to get the design right in order to prevent an unhappy client and a chilly home.
This involves conducting a thorough heat loss calculation for the property. Essentially, it means determining the amount of energy required to heat each area to a comfortable level for the client. Different rooms have different heating requirements, with an entrance hall needing less warmth compared to a bathroom.
Once the calculations for each room and hallway are completed, they are combined to provide a heat loss calculation for the entire property. Subsequently, the appropriate heat pump can be selected for the property. If the heat pump is oversized, it will consume more energy, resulting in higher energy bills.
When installing a heat pump, it is important to carefully plan its placement.
Ideally, the heat pump should be positioned near the property to minimize the length of the outside pipes, but it should also be far enough away to avoid causing any inconvenience.
Another factor to consider is the potential for cold air to be emitted from the front of the unit, making it less than ideal to place the heat pump near seating areas on a patio.
If there is limited floor space, wall hanging the units is always an option.
Commissioning entails verifying that all instructions provided by the manufacturers have been followed, including filling the system and ensuring proper functionality. This involves checking the functionality of isolation valves and switches, as well as confirming that antifreeze levels meet the necessary requirements.
Additionally, it involves labelling important components of the system. It is important to note that slight adjustments to settings or parameters may be necessary for different systems, as manufacturers have dedicated significant resources to optimising their systems.
Finally, completing the Benchmark certificate and any other relevant paperwork is also part of the commissioning process.
The handover process involves ensuring client satisfaction with the installation. It is important to remember that clients may forget or have a limited understanding of certain aspects, so it is encouraged to reach out and ask questions via phone (this is normal).
Additionally, the client should be given an explanation on how the system operates and how to recharge it if necessary. The user controls should be demonstrated and understood by the client.
Finally, all necessary paperwork, including insurance certificates and instruction manuals, should be left with the client.
