What makes up the heating system in a building?
A building has at least two internal distribution systems that must be heated—one system for supplying heat to the radiators and one system for distribution of domestic hot water. Sometimes, a separate system also provides heat for heating the supply air in the mechanical ventilation system. Each internal system is heated and regulated separately.
What should the temperature be in the boiler room?
Boiler room temperatures at the burner fan inlet should be controlled between 50°F and 100°F in order to limit variability in the amount of combustion air delivered to the burner.
What happens to the air supply when a boiler is closed?
Temporary air intakes such as open boiler room windows can be closed (and often are when persons in the boiler room are feeling cold), cutting off the boiler’s air supply. When the combustion air supply is closed off, the fire starts to smoke as the air supply is exhausted. Incomplete combustion occurs and carbon monoxide is generated.
How is hot water released from a boiler?
As the flame and exhaust gases pass over the tubes of the heat exchanger, the water inside absorbs heat. The hot water is pumped to the baseboard heaters/radiators to release its stored heat before returning to the heat exchanger to repeat the process. This is called the boiler water loop, since it is a circular system.
Where are gas fired boilers not to be located?
Appliances shall not be located in sleeping rooms, bathrooms, toilet rooms, storage closets, or surgical rooms, or in a space that opens only into such rooms or spaces. Appliances should be located so as not to interfere with proper circulation of combustion, ventilation and dilution air.
What are the minimum requirements for a gas fired boiler?
Minimum requirements (as listed in Table M2003.2) are specified below: a Based on average water temperature of 195 ° F, fill pressure of 12 psig, and a maximum operating pressure of 30 psig. b System volume includes volume of water in boiler, convectors, and piping, not including the expansion tank.

How is a boiler different from a furnace?
Whereas a furnace directly transfers heat from combustion to supply air in the air distribution unit, a boiler heats a secondary transfer fluid (typically water, but sometimes steam) that is, in turn, pumped through a radiation/convection system located throughout a building or home. The hot water can also be used to heat air via a coil and blower.
