Preface

This is the first edition of the CSA F379 Series, Packaged solar domestic hot water systems (liquid-to-liquid heat transfer). It replaces the previous editions of CSA F379.1, Solar Domestic Hot Water Systems (Liquid-to-Liquid Heat Transfer) and CSA F379.2, Seasonal Use Packaged Solar Domestic Hot Water Systems, published as stand-alone documents in 1988 and 1989, respectively.

This Series was developed in response to the need for an updated document that, together with CSA F378, specifies safety and performance criteria for packaged solar domestic hot water systems. Since the last editions of CSA F379.1 and CSA F379.2, significant advances have been made in solar domestic water heater technology.

This Series includes a simple calculation for converting "standard day" results into a prediction of seasonal performance for any location in Canada.

CSA acknowledges that the development of this Series was made possible, in part, by the financial support of Natural Resources Canada (Office of Energy Efficiency and CANMET), the Ontario Ministry of Energy, BC Hydro, and Manitoba Hydro.

These Standards are considered suitable for use for conformity assessment within the stated scopes of the Standards.

This Series was prepared by the Subcommittee on Packaged Solar Hot Water Systems, under the jurisdiction of the Technical Committee on Renewables and the Strategic Steering Committee on Performance, Energy Efficiency, and Renewables, and has been formally approved by the Technical Committee. It will be submitted to the Standards Council of Canada for approval as a National Standard of Canada.

Notes:

(1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.

(2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.

(3) This publication was developed by consensus, which is defined by CSA Policy governing standardization - Code of good practice for standardization as "substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity". It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this publication.

(4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee.

(5) All enquiries regarding this Standard, including requests for interpretation, should be addressed to Canadian Standards Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6.

Requests for interpretation should

(a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;

(b) provide an explanation of circumstances surrounding the actual field condition; and

(c) be phrased where possible to permit a specific "yes" or "no" answer.

Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are published in CSA's periodical Info Update, which is available on the CSA Web site at www.csa.ca.
