Boilers and radiators are not often installed in new homes, but many
older residences still feature this type of heating system. Furthermore,
because this type of heating works well in multi-residence situations
and larger buildings, steam heating and hot-water heating are still
common in many apartment buildings, multi-family dwellings, and older
business buildings.
Steam Heating Systems: Pros
Steam and hot-water heating systems have several benefits that aren't
often discussed. They have few moving parts, making them more reliable
and durable if maintained than newer, more complicated heating systems.
They also provide clean and dust-free heat, a huge plus for homeowners
who react negatively to the dust and other allergens that can be stirred
up by forced air and other modern heating systems. Finally, they fit
the bill when it comes to staying true to older structures and historic
homes, making it easy to see why some homeowners choose to overlook, and
put up with, some of the quirks that have made steam heating systems
lose popularity as a residential heating option over the years.
Boiler Systems Operation
In steam heating systems, a boiler heats water by means of a gas or
oil-fired burner and turns it into steam. The steam travels through
pipes to radiators or convectors, which give off heat and warm the room.
As the steam cools, it condenses back into water, and returns to the
boiler to be heated again. Hot water heating systems operate on the same
principle, using hot water instead of steam to heat the radiators.
Steam Heating Systems Maintenance
While one of the advantages of boiler systems is their long life, they
should still be serviced annually to ensure trouble-free operation. You
can easily learn to check the safety valve, pressure level gauge, and
water level gauge yourself, but for safety reasons more substantial
heating system maintenance should be done by qualified service
professional. Routine annual service should include checking the
controls and gauges and inspecting and adjusting the burner. In
addition, the chimney and flues from the boiler should be inspected for
blockages or leaks, as well. If you have steam heating, the air valves
on the radiators should also be checked and adjusted to regulate the
heat.
