This draft standard describes the code of practice for planning and construction of drinking water systems in houses and properties as well as the components, apparatus and materials which are to use. It supplements DIN EN 806-2 and gives additional specifications considering national laws, regulations and German Technical Rules.
This European Standard defines the specifications and test methods for the construction, safety, rational use of energy and fitness for purpose, environment and classification and marking of gas-fired storage water heaters for domestic hot water uses. This standard applies to appliances :a) of types B11, B11BS, C11, C12, C13, C21, C31, , C32, C33, C42, C43, C51,C52, C53, C62, C63, C72, C73, C81 connected to an individual flue duct, C82 and C83; b) fitted with atmospheric burners; c) using one or more combustible gases corresponding to the three gas families and the pressures indicated in EN 437; d) of nominal heat input not exceeding 150 kW (net calorific value); e) using or not the water condensation heat in the combustion products; f) fitted with electrically operated mechanical flue dampers that are positioned downstream of the heat exchanger and tested as an integral part of the water heater; g) appliances whether subject to the water mains pressure or open-circuit.
This British Standard specifies requirements for the selection,installation, inspection, commissioning and maintenance of gas‑firedwater-heating appliances, which have a rated heat input notexceeding 70 kW, based on net calorific value.It applies to water-heating appliances utilizing 1st, 2nd or 3rd familygases designed to operate in the condensing or non‑condensingmode for the supply of hot water for domestic purposes in domesticdwellings or domestic dwellings in commercial premises.This standard does not apply to:a) water-heating appliances with a rated input of over 70 kW;b) hot water supply systems in multiple dwellings supplied from acentral source.It does not cover the detailed design and installation of the whole hotwater distribution system, which was specified in BS 5449.This standard applies to water-heating appliances which carry aCE mark and also to previously used water-heating appliances whichdo not carry the CE mark (see 5.3.1).
This European Standard is applicable to solar supported gas-fired appliances producing domestic hot water. Itapplies to a system marketed as single unit or a system fully specified by a manufacturer that: has a gas heat input not exceeding 70 kW; and has a hot water storage capacity not exceeding 500 l; and is equipped with at least one solar collector; and is, with regard to the solar hydraulic circuit, considered as a forced circulation system (definition accordingto EN ISO 9488:1999).The appliances covered by this European Standard are described in Annex C.This European Standard does not apply to thermo-siphon or integral collector storage systems (definitionsaccording to EN ISO 9488-1999).NOTE In principle, the energy consumption of thermo-siphon solar preheat systems and integral collector storagepreheat systems can also be assessed on the basis of this standard. One appropriate procedure for that purpose is tocalculate the temperature level of the domestic hot water withdrawn from the thermal solar system for the referenceconditions defined in this standard by using the numerical system model and the thermal solar system performanceparameters according to ISO 9459-5. Based on the temperature level of the hot water withdrawn from the store the energyconsumption of the gas appliance should be determined. This determination can either be done by means of calculationsor by performing a test according to EN 13203-2 and using instead of the cold water inlet temperature the hot watertemperature withdrawn from the store.This standard is not intended to assess the performance: of the solar collector(s), which should comply with EN 12975-1 and EN 12975-2; and thermal solar systems and components, which should comply with EN 12976-1 and EN 12976-2.This European Standard, EN 13203-3, sets out a method for assessing the energy performance of a solarsupported appliance. It defines a number of daily tapping cycles for each domestic hot water use, kitchen,shower, bath and a combination of these, together with corresponding test procedures including informationabout the available solar radiation. It enables the energy performances of different gas-fired appliances to becompared and matched to the needs of the user.
