CE conformity for Gas storage water heater
For Gas storage water heater, the applicable CE scope is determined from intended use, energy sources, safety architecture and target market. The risk assessment, technical file, testing and conformity route must be verified against the actual model.

Direct response to the scope
CE conformity for Gas storage water heater — Define the product boundary first
Unlike instantaneous drivers, gas-filled boilers store hot water in a tank and keep it hot for a long time. The burner, combustion tube or gearbox can transmit heat from or through the bottom of the tank. A malfunction of the thermostat, a drop in the lime layer or water level can cause local overheating, boiling, and tank tension. The position of the independent safety limiter with the working thermostat, the method of re-starting and the behavior after power outages are evaluated.
If the storage tank is connected to the network pressure, the enlargement, valve and closed outlet scenarios are important. The safety valve, exhaust line, maximum operating pressure and material resistance must be consistent. The PED assessment is done in the form of PS, volume, fluid group, temperature and equipment marketed. The special exclusion rule of the PED for the pressurized parts of the GAR-compliant device is also taken into account; therefore, the result is not written only by looking at the value of the liter or bar.
In the basic model, the loss of traction and the return of the combustion product to the room, while in the hermetic model, fan and terminal resistance are the main hazards. If the tank is kept at a low temperature for a long time, hygiene management; if it is kept too high, the risk of frosting arises. Product instructions explain the temperature setting, the need for thermostatic mixing, periodic safety valve control, annotation maintenance and lime cleaning. In frosted areas, the discharge method is specified. If there is a built-in design, the material and drainage compliance of the tank is shown in the technical file. The approved organization is the type of the GAR and the production conformity of the selected product; the manufacturer in the production process represents the temperature and the final working time of the tank. This is the required temperature and temperature controls, and the fuel supply, the fuel pump, the fuel pump, the fuel pump, the fuel pump, the fuel pump, the fuel pump, the fuel pump, the fuel pump and the fuel pump are not tested.

Technical features that change the evaluation
The following data shows why even models with the same product name can change the path of conformity.

Risk architecture
The main dangers to be addressed in the file
The protective, control and verification approach shall be based on the actual product cycle.
Excessive hot water
A thermostat failure can cause boiling or frostbite; independent limitation and mixing measures are taken when necessary.
The corrosion of the tank
Coating defects, incorrect annotations or water chemistry can lead to leakage; material selection and maintenance conditions are defined.
Loss of bucket traction
The combustion product can be returned to the site; the check-in, terminal and installation conditions are verified according to the type of product.
Local heating due to friction
The accumulation on the heat transfer surface increases the metal temperature and impairs yield; water quality and cleaning range are specified.
Fire safety valve evacuation
The hot water from the valve shall not reach the user; the direction, diameter and freezing condition of the exhaust pipe shall be explained in the instructions.
The conditional law matrix
When will the regulation take effect?
A single product name doesn't give the same answer for all models.
| The subject | The situation | Product-based evaluation |
|---|---|---|
| GAR 2016/426 | YES, YES | The device that produces the storage water by burning gas is within range. |
| Authorized organization | YES, YES | Type and serial production conformity under the GAR is complemented by third party tasks. |
| PED | IT 'S A MESS . | The specific PED rule under GAR is examined together with the tank's PS, volume and category account. |
| LVD and EMC | IT 'S A MESS . | The fan, pump, electronic ignition or network connection is evaluated in the variant. |
| The Commission shall adopt delegated acts in accordance with Article 21 of Regulation (EU) No 1303/2013. | IT 'S A MESS . | The requirements for energy efficiency, emissions and product information up to 400 kW are confirmed in the in-complex gas water heater. |
| Energy label (EU) 812/2013 | IT 'S A MESS . | The water heater up to 70 kW shall be labelled and the product fiche shall be inspected; if the part is offered as a separate hot water tank, the 500-liter limit shall also be examined. |
| ATEX | NO , NOT AT ALL . | Normal size use is excluded from ATEX equipment because it contains only gas. |
Standard and verification approach
- EN 89: Stored gas is the basic product standard in fuel-fired water heaters to the extent that it meets the device capacity and structural range.
- EN 437: The gas category describes the experimental gas and feed pressure conditions.
- EN 13611: The gas may be used to assess the product-related characteristics of safety and control arrangements.
- EN 298: In the case of an automatic brush control system, the design is applied for fire and flame monitoring with comprehensive verification.
- EN 1490: If a combined heat and pressure discharge valve is used in building water systems, it may be relevant in terms of component selection.
Important distinction
CE conformity for Gas storage water heater — Product conformity is a separate study.
ISO management system certification does not replace product-specific risk analysis, test evidence and compliance file.
The compliance work plan
In what order will the technical preparation proceed?
Collecting device and tank data
The volume, PS, temperature, power, combustion chamber, barrel and water contact materials are recorded.
GAR-PED scope analysis
The classification, exclusion and category rules for pressure-sensitive parts with the gas appliance are justified.
Model family and risk plan
The largest volume, highest power, pressure and barrel configuration are linked to representative experiments.
Test and verify
Gas, combustion, tank, temperature, pressure, barrel and electrical evidence are examined in the selected GAR path.
Serial production warranty
The source, coating, tank test, safety valve, gas setting, label and instructions are recorded.

Frequently Asked Questions
CE conformity for Gas storage water heater — Technical answers about
Does the driver fit the same test as the gas-sized ones?
No, the storage tank in the sizes requires additional assessment of heat expansion, long-term heat retention and corrosion risks.
Is the Boiler Tank definitely covered by PED?
No definitive result is given unless the PED ruling on GAR devices is examined together with the PS, volume, fluid and category account.
Does the safety valve have to be delivered with the device?
The protection arrangements and characteristics necessary for the safe installation of the design must be defined by the manufacturer; the form of supply must be clear in the conformity strategy.
Will the change of notes affect the technical file?
Since the annotation material and size affect the corrosion life, the relationship to water chemistry, tank material and approved design is evaluated.
What is studied in addition to the combat size?
Topics such as acidity of the runoff water, drainage material, slope, exchanger corrosion and freezing of the exhaust are added.
Can the same burner be used in different tank volumes?
The power density, the circulating behavior, the extreme temperature and the bucket performance must be confirmed by representative evidence for each volume family.
