Manufacturers’ technical instructions

Central heating systems and components must be installed, commissioned and
maintained strictly in accordance with manufacturers’ instructions. If these are
not available or have been misplaced, most manufacturers now have the facility
to download the instructions from their websites.

Operating principles and system
layouts of central heating systems and

components

Central heating is a vast and complex subject. There are now more options
with regard to system types, sources of heat, pipe materials and heat emitters
than ever before. Environmentally friendly technology and the re-emergence of
underfloor heating have meant that the customer can now afford to be selective
about the system they have installed into their property. The advent of heat
pumps and solar systems, with the accompanying savings on fuel and running
costs, has dramatically lowered the carbon footprint of domestic properties. No
longer does the customer have to rely on appliances that burn carbon-rich fuels
such as gas and oil. Zero-carbon and carbon-neutral fuels have revolutionised
domestic heating, while advances in technology have lowered the cost of the
energy-saving appliances that formerly were available to only a select few.
