2.18.3.3.1 Compliance
Heat pumps shall comply with the Technical Requirements. Issues to be taken into account include:
- relevant standards
- product certification
- operative competency.
8.3.3.1.1 Relevant standards#
Heat pumps should comply with relevant standards including where applicable:
| BS EN 14511-1 | ‘Air conditioners, liquid chilling packages and heat pumps for space heating and cooling with electrically driven compressors for space heating and cooling’. Terms and definitions |
| BS EN 14511-2 | ‘Air conditioners, liquid chilling packages and heat pumps for space heating and cooling with electrically driven compressors for space heating and cooling’. Test conditions |
| BS EN 14511-3 | ‘Air conditioners, liquid chilling packages and heat pumps for space heating and cooling with electrically driven compressors for space heating and cooling’. Test methods |
| BS EN 14511-4 | ‘Air conditioners, liquid chilling packages and heat pumps for space heating and cooling with electrically driven compressors for space heating and cooling’. Requirements |
| BS EN 16147 | Heat pumps with electrically driven compressors requirements for domestic hot water |
| BS EN 12102-1 | Determining the sound power level of compressors |
| BS EN 14825 | Calculation of seasonal performance |
| BS EN IEC 62108 | Requirements for assessing the products capacity for long term operation in general open-air climates |
| MIS 3005- d | Microgeneration Certification Scheme requirements for the supply, design of heat pump systems |
| MIS 3005 - i | Microgeneration Installation Standard for heat pumps installation |
| Fluorinated gas (F) Gas | Guidance for users, producers and traders of HFCs, PFCs and SF6 |
| CC 002 | Micro generation heat pump compliance certificate (commissioning standard) |
| MCS 007 | Heat pump standard |
8.3.3.1.2 Product certification#
Heat pump technologies should have current certification confirming satisfactory assessment by an appropriate independent authority acceptable to NHBC.
Systems, products and installations that are assessed through the Microgeneration Certification Scheme (MCS) will generally be acceptable to NHBC. Certification and test documentation should be made available to NHBC upon request.
Other certification bodies or test documentation may be acceptable where they are considered by NHBC to be a suitable alternative.
8.3.3.1.3 Operative competency#
Heat pump systems should be installed by operatives:
- competent and familiar with the system being installed, and
- MCS registered or
- certified to a standard acceptable to NHBC.
Where installers are not MCS accredited they should still hold the relevant qualifications:
- completed an approved British Plumbing Employers Council (BPEC) training course for Heat Pump Systems and Low temperature hot water heating systems
- electrically qualified
- F Gas registered
- registered to install unvented cylinders.
