EXECUTIVE SUMMARY This is the Final Task 2 report oF the preparatory review study on the Ecodesign Commission Regulation (EU) No. 814/2013 and Energy Label Commission Delegated Regulation (EU) No. 812/2013 For (dedicated) water heaters and hot water storage tanks. Task 2 not only serves as an update oF market Figures For the subsequent Tasks, Following the MEErP methodology, but also reviews speciFic aspects mentioned in Article 7 oF the regulations and evaluates the eFFectiveness oF the current regulations in as much as can be derived From market data. Most raw stock and sales data were produced by subcontractor BRG Building Solution. Other data and the elaboration oF BRG data was done by VHK. Generic economic data Eurostat production and trade data For water heaters are largely inconclusive, because the 8-digit (CN8) product groups contain also items that are not in the scope oF the Ecodesign and Energy Label regulations For water heaters, such as electric kettles and solid Fuel water heaters. Hot water storage tank are not speciFied as such in any statistical 8-digit product group. Stock In 2014, according to BRG, 89 million EU dwellings (36% oF total) used dedicated water heaters as a primary source oF sanitary hot water. Apart From that, there are around 53 million secondary dedicated water heaters, used as single tap solution e.g. For the kitchen or bathroom sink. Also in the scope oF current water heater regulations are the standing losses oF 40 million indirectly heated cylinders. The energy eFFiciency oF the boilers heating those cylinders as well as the energy eFFiciency oF combi-boilers (65 million installed) and large boilers For collective heating oF 21 million dwellings are in the scope oF the Ecodesign and Energy Label boiler regulations, i.e. not the water heater regulations discussed here. District heating equipment to supply water heating solutions (24 million dwellings) is not regulated under Ecodesign or Energy Label legislation. For the non-household sector it is estimated that the number oF hot water tapping points is approximately one-third oF that oF the household sector. Sales Total EU water heater sales, including combi-boilers, dropped over 15% aFter the 2007 Financial crisis, i.e. From 18.5m units in 2006 to 15.6m units in 2016. Since 2012 the sales are more or less stable at this level. Dedicated water heaters are some 60% oF unit sales (9.5m units). Largest riser is the (monobloc) Heat Pump Water Heater, selling 136k units in 2016, 109k more than in 2007. Sales oF solar thermal panels are declining at a rate oF over 6% per year. The largest sales drop, on aggregate 50% over the last decade, comes From gas-Fired storage water heaters (GSWHs). Reliable energy eFFiciency data For water heaters is as yet scarce. ManuFacturer’s association APPLiA was able to supply a data-set For electric water heaters, but For Fossil- III Fuel Fired and solar water heaters eFFiciency data are estimated on the basis oF technical characteristics. According to new Eurostat statistics the total 2015 residential energy consumption For all water heating, including combi-heaters and excluding water heating From solid Fuel boilers, is around 1978 PJ (47.2 Mtoe) in primary energy. Including an extra one-third For non-household applications this amounts to 2637 PJ (62.9 Mtoe) primary energy. Prices and rates Energy prices increased considerably less, or even declined, compared to the trend beFore 2011. This means that the more comprehensive LiFe Cycle Cost calculation method will have to be used in Future tasks. Product prices were derived From on-line oFFers. Market actors Suppliers oF dedicated water heaters and storage tanks are mainly large companies, although there are also some larger SMEs that are active in the Field. The interim Task 2 report From December 2017 has not stimulated stakeholders to give more speciFic inFormation over the course oF 2018 and thus to draw any Firm conclusions regarding the eFFectiveness oF the current water heater regulations is premature. Once manuFacturers have Filled the database oF the European Registry For Energy Labelling (EPREL)1 in June 2019, it should be possible to have a better insight. 1 Since 14/12/2018 the EPREL database is online product registration: https://energy-label.ec.europa.eu.
