A Guide to Energy-Efficient Heating and Cooling

Check all gas (or oil) connections, gas pressure, burner combustion, and heat exchanger. Improper burner operation can be caused by a dirty burner or a cracked heat exchangereither can cause the equipment to operate less safely and efficiently. Leaking gas (or oil) connections are also a fire hazard and can contribute to health problems.

Troubleshooting a Circulator Pump | DoItYourself.com

Aug 23, 2018 · A boiler's circulator pump is used to remove hot water from the boiler, and then pass it into heating devices such as the radiator or a convection pipe system. The power of the pump is enough to cause the water to travel right back up to the boiler from the pipework. Using a circulation pump is a great way of keeping water traveling throughout the system.

Three-drum boiler - Wikipedia

Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships.They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.
