1. Working Principle Comparison<\/strong><\/h2>\n\n\n\n

\ud83d\udd39 Gas Boiler System<\/strong><\/h3>\n\n\n\n

A gas boiler<\/strong> generates heat by burning natural gas (NG), liquefied petroleum gas (LPG), or other combustible gases<\/strong>. The released heat is transferred to water via a heat exchanger<\/strong>, producing steam or hot water<\/strong>. Key components include:
\u2714 Quemador<\/strong> (for combustion)
\u2714 Heat exchanger<\/strong> (transfers heat to water)
\u2714 Water supply system<\/strong>
\u2714 Control & safety systems<\/strong><\/p>\n\n\n\n

\ud83d\udd39 Electric Thermal Oil Heater<\/strong><\/h3>\n\n\n\n

An electric thermal oil heater<\/strong> uses electrical resistance heating<\/strong> to warm thermal oil<\/strong>, which is then circulated via a pump to deliver heat. Main components:
\u2714 Electric heating elements<\/strong>
\u2714 Expansion tank<\/strong> (accommodates oil expansion)
\u2714 Circulation pump<\/strong>
\u2714 Filtration & control systems<\/strong><\/p>\n\n\n\n
