Gas Boiler Repair and Installation

Quiet, Consistent Comfort: A Perfect Pair with Your Radiant System.

In the United States, natural gas is the most common fuel for fired boilers today. It is an easily accessible resource and a cheap heating fuel. Unlike liquid propane or oil fuels, you don’t need to have a truck deliver it to your house—a gas line already runs underneath most homes. Home owners have the very convenient option to heat their house and provide heated water throughout their home with this single appliance.

Using Natural Gas

Carrier FurnaceNatural gas, supplied to the home by an underground main line, is fed through a small pipe leading into your home. When the thermostat triggers the boiler to heat the house, a valve opens, releasing the natural gas into a combustion chamber in the form of small jets. An electric spark ignites the fuel. The fire heats the water-filled pipes that circulate through your home. The pipes connect to a radiator where the heated water emits heat energy into the room. Once the heat is exhausted into the air, the cooled water returns through the pipes leading back to the boiler to be reheated and circulated again.

About Condensing Boilers

Boilers have become much more energy efficient over the years. Different models of gas boilers have emerged, but condensing boilers are the most energy efficient today. In a typical gas boiler, there is a return flue at the bottom and another flue at the top. When air in the room cools, it is collected into the return flue to be reheated. In a condensing gas boiler, the return flue is actually connected to a condensing chamber where hot steam and condensation is usually collected and expelled outside of the home. The hot steam can be reused to heat the cooled water and, therefore, allows the boiler to work less to heat the water and air.

Benefits of Gas Boilers

  • Natural gas is the cleanest burning fuel, contributing to the safety of our environment.
  • Natural gas is an abundant, natural resource and is a very inexpensive source of energy.
  • Gas boilers can operate to heat both your home’s water and air in a single machine.
  • With natural gas, there is no storage tank or reserve for fuel.
  • Efficient models, such as condensing gas boilers, have an AFUE (annual fuel utilization efficiency) rating of 90% or greater.
  • Electric ignition of gas eliminates the need for a pilot light for the duration of the boiler’s operation.
  • New combustion technologies allows for more efficient heating without using additional fuel.
  • Heating of the air and water occurs more quickly than other heating appliances.

Other Considerations to Gas Boilers

  • Expensive Initial costs to install a gas boiler, including the hook up for natural gas.
  • Natural gas may not be available in your area.
  • Requires an experienced, qualified expert to hook up natural gas into your home.
  • Fires or explosions caused by a gas leak can cause fatal injuries and extensive damage to the home. Inspections of your gas line and heating equipment is highly recommended in the maintenance of your boiler.
  • A separate water storage tank is typically required for potable water.
