What is BS EN 13203-4 - Gas-fired mCHP appliances about?
BS EN 13203 discusses gas-fired domestic appliances producing hot water. BS EN 13203-4 is the fourth part of BS EN 13203 multi-series and discusses the assessment of energy consumption of gas combined heat and power appliances (mCHP) producing hot water and electricity.
BS EN 13203-4 applicable to gas-fired mCHP appliances producing domestic hot water and electricity. The electricity is generated in a process linked to the production of useful heat. It applies to mCHP appliances marketed as a single unit or as a package fully specified by a manufacturer that has:
- A gas heat input not exceeding 70 kW
- An electrical output not exceeding 50 kW and
- A hot water storage capacity not exceeding 500 l
Note: When the mCHP generator does not supply domestic hot water in the summer period, BS EN 13203-4 is not applicable. EN 13203-2 is used for the performance assessment of these generators.
Who is BS EN 13203-4 - Gas-fired mCHP appliances for?
BS EN 13203-4 on gas-fired mCHP appliances is useful for:
- Gas-fired appliances manufacturers
- Quality control personnel
Why should you use BS EN 13203-4 - Gas-fired mCHP appliances?
Micro combined heat & power (mCHP) is an innovative high-efficiency energy solution that uses natural gas to generate both heat and electricity for your home by capturing the excess thermal energy that would normally be lost during power generation.
BS EN 13203-4 provides you with a method for assessing the energy performance of gas-fired mCHP appliances. It defines several daily tapping cycles 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.
