Designation:E105613Standard Practice forInstallation and Service of Solar Domestic Water HeatingSystems for One-and Two-Family Dwellings1This standard is issued under the fixed designation E1056;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice provides descriptions of solar domesticwater heating systems and sets forth installation and servicepractices in new and existing one-and two-family dwellings tohelp ensure adequate operation and safety.2,31.2 This practice applies regardless of the fraction of heat-ing requirement supplied by solar energy,the type of conven-tional fuel used in conjunction with solar,or the heat transferfluid(or fluids)used as the energy transport medium.However,where more stringent requirements are recommended by themanufacturer,these manufacturer requirements shall prevail.1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.For specificprecautionary statements,see Sections 6 and 7.2.Referenced Documents2.1 ASTM Standards:4E772 Terminology of Solar Energy Conversion2.2 SMACNA Standards:5Medium Pressure Duct Construction StandardsFibrous Glass Duct Construction StandardsFlexible Duct Performance and Installation Standards2.3 NFPA Standard:NFPA 321 Basic Classifications of Flammable and Combus-tible Liquids62.4 ANSI Standard:Z 21.22 Relief Valves and Automatic Gas Shut Off Devicesfor Hot Water Supply Systems73.Terminology3.1 Definitions:3.1.1 auxiliary energy subsystem,nin solar energyapplication,equipment using nonsolar energy sources tosupplement or backup the output provided by a solar energysystem.(E772)3.1.2 flash point,nof a liquid,the minimum temperatureat which it gives off vapor in sufficient concentration to form anignitable mixture with air near the surface of the liquid withinthe vessel as specified by appropriate test procedure andapparatus.(See Terminology E772 and NFPA 321.)3.1.3 heat transfer fluid,n(1)in solar energy systems,aliquid or gas that passes through the solar collector and carriesthe absorbed thermal energy away from the collector.(2)anyfluid that is used to transfer thermal energy between subsys-tems in solar energy systems.(E772)3.1.4 operating conditions,extreme,n unusual physicalconditions to which a component or system may be exposedand for which it is not designed or intended to withstand,noris it required to withstand by a local regulatory agency.(E772)3.1.5 operating conditions,normal,nthe usual range ofphysical conditions(for example,temperature,pressure,wearand tear,weather)for which the component or system wasdesigned.(E772)1This practice is under the jurisdiction of ASTM Committee E44 on Solar,Geothermal and OtherAlternative Energy Sources and is the direct responsibility ofSubcommittee E44.05 on Solar Heating and Cooling Systems and Materials.Current edition approved Nov.1,2013.Published December 2013.Originallyapproved in 1985.Last previous edition approved in 2007 as E105685(2007).DOI:10.1520/E1056-13.2Dikkers,R.,“Performance Criteria for Solar Heating and Cooling Systems inResidential Buildings,”Department of Housing and Urban Development andNational Bureau of Standards,September,1982.3Hollander,P.E.,“Installation Guidelines for Solar DHW Systems in One-andTwo-Family Dwellings,”Franklin Research Center,U.S.Goverment PrintingOffice,April 1979.4For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.5Available from Sheet Metal and Air Conditioning Contractors National Assoc.(SMACNA),8224 Old Courthouse Rd.,Tysons Center,VA 22180.6Available from National Fire ProtectionAssoc.,Batterymach Park,Quincy,MA02269.7Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.6 solar energy system,active,na solar energy systemthat uses mechanical equipment(pumps,fans),that is not anintegral part of a structure,to collect and transfer thermalenergy,either to the point of use or to be stored for later use.(E772)3.1.7 solar water heating systems,direct,na solar waterheating system in which the potable water passes
