Gas-fired boiler
Gas-fired boilers are very reliable heating systems with low operating costs requiring minimal maintenance. Hot water boilers or steam boilers are used in the industrial sector, factories, manufacturing plants, hospitals, schools and other institutions.
They are clean burning, without soot, ash or smoke and have a very low carbon content which will help minimise the effects of any carbon tax.
In many cases, especially in schools, coal fired burners are being converted to gas-fired boilers, eliminating the need for storage and handling of coal, and gaining extra space and considerable savings on maintenance time and costs.
Selection and design
Boilers are available assembled or unassembled, with high-efficiency models able to be turned on/off for ‘even’ building heating.
The size of a gas-fired boiler is dependant on its intended application. The boiler selected primarily for satisfying hot water demand, perhaps for the purpose of running a central heating system, will be different from the boiler required to create steam to power machinery.
Installation/location
Gas-fired boilers are normally installed in the plant room. Connections are required to a gas supply, an exhaust flue, hot water flow and return piping, and an electrical switchboard.
Conversion from coal fired boilers to gas-fired boilers utilises the existing location, and results in freeing up the space previously needed for coal storage. Typically in schools this is between 12 and 26 square metres.
