Home Heating System Basics: Gas Boilers

Posted on

If you have radiator heating in your Montgomery County, Maryland, or Washington, D.C. home, it is a good idea to have your Maryland gas boiler serviced by an HVAC professional.  This way, you can make sure your home is heated all winter long.

What is a gas boiler?

A gas boiler is a pressure vessel, usually made of steel and located in the lowest level of your home.  Gas boilers convert liquid to steam, and the steam is carried to radiators in older homes.  These radiators heat individual rooms throughout the house.

Benefits of a gas boiler

Gas boilers help homeowners save more money because gas boilers run more efficiently than oil boilers and natural gas is cheaper than oil.  As a result, heating costs are lower than if you were paying for oil and also paying a company to come and fill up your tank with oil each time you were running low.  While gas boilers are fed directly from a gas line, oil boilers have the chance of running out in the middle of winter if you forget to check the fuel levels.

For more information on gas boilers, or to schedule an appointment for your heating system to get checked by an HVAC expert, call Michael Bonsby Heating & Air Conditioning.

How to troubleshoot a gas boiler

Before calling an HVAC professional to come service your gas boiler, there are a few things you can do to troubleshoot your system. Some of these steps are:

  1. Check your pilot light.  If you pilot light is out, you will  either need to relight it or call an HVAC technician to come and relight it so that your boiler continues working.  Be sure to test if you smell any gas, which could be a sign of a dangerous gas leak.
  2. Check your thermostat to make sure it is set at the correct temperature.
  3. Check for leaks around your boiler.  This could be water or fuel that leaked from the tank or line.
  4. Check the breaker that supplies power to the gas boiler.  Try resetting the breaker to see if that helps.

If you cannot determine your gas boiler problem, call an HVAC technician to come to your home and service your boiler.
