Microgeneration Certification Scheme: MCS 007 Product Certification Scheme Requirements: Heat Pumps Issue 4.0 This Microgeneration Product Certification Standard is the property of Department of Energy and Climate Change (DECC), 3 Whitehall Place, London,SW1A 2HH. © DECC 2013 This Standard has been approved by the Steering Group of the Microgeneration Certification Scheme. This document has been prepared by the MCS Working Group 6 ‘Heat Pumps’. REVISION OF MICROGENERATION PRODUCT CERTIFICATION STANDARDS Microgeneration Product Certification Standards will be revised by issue of revised editions or amendments. Details will be posted on the website at www.microgenerationcertification.org Technical or other changes which affect the requirements for the approval or certification of the product or service will result in a new issue. Minor or administrative changes (e.g. corrections of spelling and typographical errors, changes to address and copyright details, the addition of notes for clarification etc.) may be made as amendments. The issue number will be given in decimal format with the integer part giving the issue number and the fractional part giving the number of amendments (e.g. Issue 3.2 indicates that the document is at Issue 3 with 2 amendments). Users of this Standard should ensure that they possess the latest issue and all amendments.

At the time of publication, the editions indicated were valid. All documents are subject to revision, and parties applying this document MCS 007 are encouraged to investigate the possibility of applying the most recent editions of the documents referenced. The following document (MCS 007 Issue 4.0) is a major update to MCS 007 issue 3.0. It is available for reference from the date of publication 01/05/2015. Manufacturers or importers of microgeneration systems who have certificated a microgeneration product in accordance with MCS 007 may commence working in accordance with this update from 01/05/2015. Energy Related Product Directive (ErP) ERP comes into force on the 26/09/2015, after this date all products not already in the market place must be produced/manufactured/imported in line with the ErP directive and performance data has to be available on a Free to Access Website (FAW). For MCS to allow time for either currently listed products or new products to meet the new compliance standards, this standard is published on 01/05/2015. Manufacturers will be given until the 26/03/2016 to ensure all of their heat pumps meet the new criteria. New products will be subject to the requirements of this standard from 26/09/2015. Further testing may be required in the future but Factory Production Control visits and test lab accreditation will still need to be carried out. The current standards (COP and HEG) will continue to operate until the 26/03/16 giving MCS Contractors and wholesalers 6 months to clear the old pre ERP stock from their inventories. In this period, MCS Contractors will be able to use either HEG likely SPF or the new ErP criteria to establish the product SPF.

INTRODUCTION 1.1 This Scheme document identifies the evaluation and assessment requirements and practices for the purposes of certification and listing of heat pumps. Certification and listing of products is based on evidence acceptable to the Certification Body:- that the product meets the Standard; and, that the manufacturer has staff, processes and systems in place to ensure that the product delivered meets the Standard. And on: periodic audits of the manufacturer including testing as appropriate; and, compliance with the contract with the Certification Body for listing and approval including agreement to rectify faults as appropriate. 2. DEFINITIONS Low A heat pump space heater that is specifically designed for low- temperature temperature application, and that cannot deliver heating water with heat pumps an outlet temperature of 52 °C at an inlet dry (wet) bulb temperature of – 7 °C (– 8 °C) in the reference design conditions for average climate (88% part load condition for water/brine-to-water units) 3. SCOPE 3.1 This Scheme provides ongoing independent, third party assessment and approval of companies who wish to demonstrate that their heat pump meets and continues to meet the requirements of: The appropriate Standard: o EN 14511:2013 Parts 1 – 4 Air conditioners, liquid chilling packages and heat pumps with electrically driven compressors for space heating and cooling; o EN 12309-5:2014 Gas-fired absorption and adsorption heat pump appliances with a net heat input not exceeding 70 kW; or Issue: 4.0 PRODUCT CERTIFICATION SCHEME MCS: 007 REQUIREMENTS: HEAT PUMPS Date: 01/05/2015 Page 5 of 36 o EN 16147 “Heat pumps with electrically driven compressors. Testing and requirements for marking of domestic hot water units. o EN 14825:2013 Air conditioners, liquid chilling packages and heat pumps, with electrically driven compressors, for space heating and cooling. Testing and rating at part load conditions and calculation of seasonal performance. o BS EN 12102:2013.
