What is BS EN 13203-5 about?
BS EN 13203 discusses gas-fired domestic appliances producing hot water. BS EN 13203-5 is applicable to gas-fired appliances producing domestic hot water. BS EN 13203-5 applies to both instantaneous and storage gas-fired combined with an electric heat pump. BS EN 13203-5 applies to a package marketed as a single unit or fully specified by the manufacturer that has:
- A heat input not exceeding 400 kW
- A hot water storage tank capacity (if any) not exceeding 2000
BS EN 13203-5 sets out a method for assessing the energy performance of gas-fired domestic appliances combined with heat pump with electrically driven compressor according to EN 16147.
Note 1: The present BS EN 13203-5 does not apply for gas boilers with recovery systems using combustion products as heat sources for the electric heat pump.
Note 2: When the electric heat pump does not work for domestic hot water production in the summer period, BS EN 13203-5 standard is not applicable for energy performances assessing, EN 13203-2 should be used.
Who is BS EN 13203-5 for?
BS EN 13203-5 on gas-fired domestic appliances producing hot water is (Assessment with electrical heat pump) useful for:
- Gas appliances manufacturers
- Quality control personnel
Why should you use BS EN 13203-5?
Apart from preventing greenhouse emissions and conserving energy, energy-efficient gas appliances combined with electrical heat pumps producing hot water also help your customer to save money by reducing their energy bills at home.
BS EN 13203-5 sets out a method for assessing the energy performance of the appliances. BS EN 13203-5 defines several daily load profiles for each domestic hot water use, kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of different gas-fired appliances to be compared and matched to the needs of the user.
