Natural Gas Heat Advantages...
 
  • 40% less expensive.
  • Goodbye oil tank!
  • Only pay for what you use, AFTER you use it. No big bills to fill an oil tank.
  • Extremely Quiet Operation, quieter than a microwave oven.
  • Good for the Environment, both inside and outside your home, no soot, smell, oil leaks and much lower carbon and particulate emmisions than oil burners

Considering converting to gas heat? If you have oil heat you're well aware of the cost and other concerns that make oil a less popular alternative these days. However, there are a number of issues to be aware of in contemplating a conversion to gas heat.

1. Gas Supply - Do you have natural gas in the house already? If so, it makes it that much easier. If not, is it available in the street, within one hundred feet? National Grid will provide the first one hundred feet free of charge from the street to the house.  If natural gas is not available, propane (LP) could be an option for you.

2. Venting - The products of combustion must be safely moved from the boiler to the outside of your home. A masonry chimney that is tile lined CAN NOT be used for venting gas heating systems. Gas heating systems can be vented into a existing metal chimney, a stainless steel lined masonry chimney or in the case of higher efficiency units with stainless or plastic piping directly through a wall or roof.

3. Oil tank Abandonment - An unused tank must be abandoned by law. Buried tanks can be filled with foam or sand, basement tanks must be removed, cleaned out and cut in half as well as having all fill and vent piping removed. Unfortunately it happens quite frequently that a homeowner converts to gas without removing the oil tank piping and an oil company delivers mistakenly causing catastrophic damage. Removing everything is cheap insurance.

4. Boiler Selection - Standard gas boilers have efficiencies in the 82%AFUE range and are actually less efficient than the average oil boiler. You will still see a  sizable reduction in heating costs because natural gas is about 30% cheaper than heating oil at the moment but you will not be saving fuel, just burning a cheaper fuel. If gas prices were to return to parity with oil, any cost savings would disappear. 85% AFUE gas boilers are about the equal of a fairly modern oil boiler and are a better choice. 95% AFUE gas boilers are the most efficient boilers available, they vent with plastic pipe and modulate the water temperature going to the radiators and modulate the gas input as well. No other boiler can modulate the input of fuel, oil burner and gas burners are either on and firing at full capacity or off, nothing in between. 95% gas boilers  can run at anywhere from 20-100% of capacity depending upon requirements at the time. This modulation is not reflected in the AFUE rating system, so the real fuel savings with these over an 85% model is 20-25% rather than the 10% you would think.
