Most heat pump models contain a small viewing window, which provides for a quick check on whether there are any immediately obvious problems with the refrigerant gas circuit. Additionally, loss of pressure or the presence of escaped gas are clear signs that there is an issue that requires rapid investigation.
The refrigerant gases that are used are mostly harmful to the environment, although some are now being developed that have less of a negative in the event of a leak. Therefore the refrigerant circuit is sealed during production of the heat pump and should remain so for the operating lifetime of the heat pump. Any work that is carried out on it must only be done so by a fully qualified F-gas engineer – and quite often installers carrying out their own servicing do not have suitably qualified engineers, relying instead on sub-contracting out this part of the work.
Generally it is the amount of refrigerant in the heat pump unit which dictates how rigorous the requirements for examining and keeping records of refrigerant gas are. It normally follows that a larger capacity heat pump contains a larger volume of refrigerant. However, there is also variation between manufacturers as they each design for different amounts of refrigerant gas within a similar sized unit. We can advise on the level of refrigerant gas maintenance that your particular heat pump requires. We have engineers who are F-Gas certified, ensuring that when the refrigerant gas circuit undergoes maintenance, whether that be topped up or removed altogether there will be no leakage of hydrocarbons in to the atmosphere.
Your refrigerant gas circuit is vital to the efficient working of your heat pump system and any issue with it should not be left unattended to for any length of time. If you are aware that you need to have your refrigerant gas investigated, or notice that your heat pump efficiency is rapidly declining, then we have the in-house expertise to investigate and carry out work.
