Types of Boiler Explained: Combi, System & Conventional

A conventional boiler is often found in older homes, but a lot of modern homeowners choose to replace them with a system or combi boiler as they deliver higher water pressure. However, some older properties may not have pipework which can cope with higher water pressure and so need to keep using a conventional boiler system.

Boiler - Energy Education

Design considerations. The main goal when designing a boiler is to extract as much of the energy from the fuel as possible. To do so, both the fixed carbon and volatile matter must be burned completely. Since one part is solid and the other gas, this task is not easy. The boiler must be at very high temperatures, anywhere near 500 o C, and must burn the fuel continuously at a constant rate.
