How to understand a central heating system | Heating
The radiator circuits in most modern wet central heating systems are made from standard 15mm copper pipe, while the pipes that link the boiler, pump and points where the circuits split off will be 22mm or 28mm in diameter. Soldered capillary joints are best (apart from connections to the boiler, pump and valves), as these are least likely to leak.
Limited Alteration Applications. The Limited Alteration Application (LAA) is used for plumbing work, fire suppression piping replacement and repairs, and oil burner installations that do not include construction work. Generally, with the exception of some minor new installations, LAA work is restricted to repair and/or replacement of existing equipment and does not require a Professional

Solar Water Heating System - an overview | ScienceDirect
Kate Hudon, in Future Energy (Second Edition), 2014. 20.3.5 Combined Water Heating and Space Heating. Solar water heating systems can be used to provide space heating in addition to domestic hot water. These systems are common in Europe and are referred to as 'solar combisystems'. In Germany and Austria in particular, this technology is widespread and make up ~60 % of the solar collectors
An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.
