Common Breakdown and treatments of The Automatic Burning Control Device for Gas Fired Boiler

Gas-Fired Boilers and Furnaces | Department of Energy

Natural gas supplies depend on having a natural gas distribution system in your area, and areas at the end of the pipeline (such as the Northeast) tend to pay higher prices for natural gas. A number of retrofits are possible for gas-fired furnaces and boilers, but before pursuing any retrofits you should consider the potential added benefits

Oilheat America - Boilers

Boiler Designs. Originally, many oil boilers were converted from coal-burning machinery. While becoming more and more rare, some of these antiques are still being used, and these systems are plagued by high draft loss and poor heat transfer. Newer oil-fired boilers are more efficient, in part because of low-mass construction and reduced water

Troubleshooting a Circulator Pump | DoItYourself.com

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.
