variety of boilers are available
Boilers are mechanical devices that convert mechanical energy into electrical energy. A boiler is essentially a sealed box in which hot liquid is heated. The heated liquid does not actually boil. The heated or otherwise vaporized fluid enters the boiler for use in different heating processes or cooking applications, such as central heating, cooking, water heaters, or steam heating.
A variety of boilers are available, each with its own features. Boilers can be electric, fuel-burning, or combination. They can be direct-vent, vent-free, or surface-less. A water heater heats water directly, or via a system of pipes, or it may use heat exchange and direct vent. Boilers can be steam or gas-fired, depending on availability and practicality.
maintained and serviced regularly
Boilers, like all mechanical equipment, need to be maintained and serviced regularly. The type of boiler you have will determine the type of servicing you need. Gas boilers require regular maintenance and are usually covered by a home warranty; steam boilers may need to be serviced more often, but are not under home warranty. Most gas boilers are small and portable, while larger boilers are generally stationary and require professional installation. Boilers should be serviced at least once a year. In addition to servicing, a well-maintained boiler can also provide you with valuable information about your heating system.
There are many types of boilers. A water-heater can be simple and straight, with a large pot in the middle and a cylinder containing boiling water on the exterior. A water-heater in a home can include a steam locomotive boiler that looks just like a piece of furniture, and is often used to warm up a room quickly. Another example of a steam locomotive boiler is the wood-burning stove. Many older homes used these because they were cheaper than other forms of heating and did not require the frequent firing that modern fireplaces do.
several other types of boilers
There are several other types of boilers, including oil-fired and heat recovery. Oil-fired boilers are probably the most common and popular. These boilers put heat directly into the air by using a water tube, rather than a big, metal tank. Heat recovery boilers, which use a water tube in the middle of a big metal tank to store heat from the air, are less common than their oil-fired cousins. A water tube heats water and forces it into a condensing chamber where it condenses into steam. Although these boilers can produce great amounts of heat, they are less efficient than oil-fired boilers.
One type of boiler that is often used for heating is a superheater. Superheaters work by pushing hot air through a very long and narrow passage, which results in very high pressures. They are often used to provide central heating in buildings where space would be an issue. They are sometimes called “green superheaters” since they have little negative impact on the environment. Many modern superheaters are constructed out of recycled parts.
