What is BS EN 416- Gas-fired overhead radiant tube heaters about?
BS EN 416 discusses gas-fired overhead radiant tube heaters and radiant tube heater systems.
BS EN 416 specifies the requirements and test methods for the construction, safety, classification, marking, and efficiency of non-domestic gas-fired overhead radiant tube heaters incorporating a single burner and multiple burner systems (referred to in the body of the text as the “system”) with each burner unit under the control of an automatic burner control system.
For radiant tube heaters incorporating a single burner, BS EN 416 is applicable to Type A2, A3,
B12, B13, B22, B23, B42, B43, B52, B53, C12, C13, C32, C33, C52 and C53 appliances intended for use in other than domestic dwellings, in which the supply of combustion air and/or the evacuation of the products of combustion is achieved by mechanical means located upstream of the draught diverter if provided.
For radiant tube heater systems incorporating multiple tube heater segments, BS EN 416 is applicable to Type B52, B52x, B53 and B53x systems intended for use in other than domestic dwellings, in which the supply of combustion air and/or the evacuation of the products of combustion is achieved by mechanical means. BS EN 416 also includes appliances incorporating a secondary heat exchanger in the flue system.
Note: BS EN 416 is not applicable to:
- Appliances designed for use in domestic dwelling
- Outdoor appliances
- Appliances where the heat input of any individual burner unit is in excess of 120 kW (based on the net calorific value of the appropriate reference test gas)
- Appliances having combustion products evacuation ducts that are non-metallic in the flue system – except ducts downstream of a possible additional condensing exhaust gas heat exchanger. In addition, for heater systems incorporating multiple tube heaters, BS EN 416 is not applicable to
- Appliances and systems that are designed for continuous condensation within the flue system under normal operating conditions – except downstream a possible additional exhaust gas heat exchanger
Who is BS EN 416- Gas-fired overhead radiant tube heaters for?
BS EN 416 on gas-fired overhead radiant tube heaters and radiant tube heater systems for non-domestic use is useful for:
- Gas-fired heater manufacturers
- Quality control personnel
Why should you use BS EN 416- Gas-fired overhead radiant tube heaters?
Gas-fired tube heaters operate as a decentralised system. They generate heat where it is required. A tube heater emits infrared radiation via its long radiant tube. The materials used in the manufacture of these gas radiant heaters are consequently designed for durability and efficiency. Radiant tube heaters are classified as gas-fired infrared heating devices and rank among the group of decentralized heating systems.
BS EN 416 provides you with the necessary guidance for the classification of appliances which includes classification according to gases and categories, and classification according to the mode of the evacuation of the combustion products. BS EN 416 guides you with constructional requirements and operational requirements.
BS EN 416 guides you with energy efficiency which includes the general principle of measurement and calculation of radiant factor. BS EN 416 also guides you with risk assessments which include marking, instructions, marking of the appliance, and the packaging and presentation. BS EN 416 helps you to manufacture high-quality gas-fired overhead radiant tube heaters.
What’s changed since the last update?
BS EN 416:2019 supersedes BS EN 777‑1:2009, BS EN 777‑2:2009, and BS EN 777‑3:2009, which are withdrawn. Together with BS EN 17175:2019, it supersedes BS EN 416‑1:2009 and BS EN 416‑2:2006. Some technical changes include these:
- Incorporation recent state of the art radiant tube heaters
- Unique and more detailed description of the method to determine radiant factor
- Incorporating terms and calculation scheme of Ecodesign Regulation (EU) No. 2015/1188
- Minimum requirements of an optional flue gas heat exchanger
