What is BS EN 15502-1 – Requirements for gas-fired heating boilers about?
A boiler is a device which burns gas, oil, electricity, or coal in order to provide hot water, especially for the central heating in a building.
BS EN 15502 is a European Standard that discusses gas-fired heating boilers.
BS EN 15502-1 specifies the common requirements and test methods concerning, in particular the construction, safety, fitness for purpose, and rational use of energy, as well as the classification, marking and energy labelling" of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners or fully premixed burners, and are hereafter referred to as “boilers”.
BS EN 15502-1 is to be used in conjunction with the specific Parts 2 (Part 2-1 and following ones).
BS EN 15502-1 applies to boilers of types B and C.
BS EN 15502-1 applies to boilers designed for sealed water systems or for open water systems.
BS EN 15502 and BS EN 15502-1 provide requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by BS EN 15502-1 or a specific standard, the risk associated with this alternative construction will need to be assessed.
Note: BS EN 15502-1 is not intended to cover appliances intended for connection to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance.
Who is BS EN 15502-1 - Requirements for gas-fired heating boilers for?
BS EN 15502-1 on requirements for gas-fired heating boilers is relevant to:
- Manufacturers of boilers and heat exchangers
- Manufacturers of gas-fired heating boilers
- Anyone involved in the commissioning, operation and maintenance of gas-fired boilers
- Quality control, testing and inspection personnel
- Product safety authorities
Why should you use BS EN 15502-1- Requirements for gas-fired heating boilers?
A gas-fired heating boiler is an appliance using gas as fuel designed to heat water with the purpose of providing heat to a building (or portion of a building) from one point to multiple rooms using heat emitters such as radiators and convectors to transmit the heat from the water to the room. The boiler may also be used to provide domestic hot water via an indirect hot water storage tank.
The basic function of gas-fired heating boiler is to generate heat by direct heat transfer in a heat exchanger, from the combustion gasses to the water.
The boiler may include in one design more than one function. It may include for example:
- A sanitary hot water function
- A function to supply the combustion air from the outside of the building
- A function to dispose the combustion products to the outside of the building.
BS EN 15502-1 was established to deal with aspects related to:
- Safety
- Rational use of energy
- Fitness for purpose
BS EN 15502-1 contains the common requirements that are applicable for the majority of the specific boiler types.
Guidance on construction, materials, electrical safety, performance of controls, operational requirements and risk assessment for gas-fired heating boilers is discussed in BS EN 15502-1.
Thus, if you are a manufacturer or installer of gas-fired heating boilers used for building heating, by complying with BS EN 15502-1, you can ensure your products are safe, reliable and effective for use. As a result, incidents of flame failures can be minimized.
