A microbore heating system uses small-diameter pipework running from central manifolds to supply individual heat emitters. It allows rapid heat-up times and flexible installation while requiring strict limits on circuit length and heat load.
Identify the layout, components, and pipe sizes used in microbore central heating systems.
Explain the operational limits, advantages, and disadvantages of manifold-based systems.
Describe correct installation, jointing, and protection methods for microbore pipework.
