    • Check fuel flow or suction line vacuum gauge
    • Replace fuel filter and/or strainer
    • Inspect or replace nozzle
    • Check and/or clean flame sensor and air gate
    • Inspect and adjust ignition electrodes
    • Check and/or clean combustion turbulator
    • Inspect flame light-off and flame characteristics
    • Inspect condition of combustion chamber if possible
    • Check/clean/replace water gauge glass and washers
    • Lubricate the water circulator pump
    • Take a combustion efficiency and draft test if necessary
  2. Boiler Sections or Tubes and Chimney Bottom Inspection – This equipment should be inspected yearly. Residential equipment should typically be cleaned every other year. Commercial equipment should usually be cleaned every year.
  3. Boiler Enhancement – Some older boilers are really well designed, and can be modified to operate more efficiently by installing a high-efficiency oil burner into that boiler. Depending on what older model boiler you have, additional savings may be obtained by adding a separate hot water storage tank.
  4. Boiler Replacement – Some older boilers are just so inefficient that they should be replaced with a high-efficiency boiler to achieve significant savings. Cohler is a licensed NYC installer for oil burners and oil-fired boilers and hot water tanks.

How To Replace Hissing Air Valves to Save Money on Heating Costs

Replace air valves on steam heating radiators (or steam mains) if they constantly hiss-out steam when the radiator is already hot, or if the radiator does not get completely hot. Radiator shut-off valves and unions should not hiss at all.

Use only Hoffman, Gorton, or Heat Timer brand “Varivalve” air valves. You can purchase these at plumbing and heating supply houses such as: H & L Heating Supply, Marine Park Hardware, or on Amazon.com.

To change an air valve:

  1. Make sure the boiler is turned off, and that the radiator is cool.
  2. Turn the old air valve counter-clockwise while looking straight at the valve, and install the correct new valve by screwing it into the radiator threaded hole clockwise until firmly in place, with the venting hole of the air valve on top.

Pipe compound is generally not used on the threads of the air valve, however Teflon®-type tape can be used on the threads of the air valve as long as it does not obstruct the inner hole of the air valve inlet).

Use slower or faster venting air valves on steam radiators to obtain even heating throughout the building. It’s best to leave steam radiator shut-off valves in the 100% open position to avoid water buildup and loud banging noises.


Three Signs Your Boiler Is Costing You Money

  1. The boiler takes over 45 minutes to get heat to the top floor. This is a sign that your boiler is operating inefficiently and wasting fuel.
  2. Your boiler water feeder comes on often. There may be a boiler or tube leak, or a boiler return pipe leak.
  3. There’s a thick plume of steam vapor coming from your chimney. Your boiler may have a leak on top, above the normal water level.

Contact us for service if you’re experiencing any of these issues with your boiler.


Install a Thermostat to Save Money on Heating Costs

Thermostat - Cohler Fuel OilA digital set-back thermostat will allow you to automatically raise and lower the heat, so that you don’t use any unnecessary fuel to heat your home or business when you’re not home, or when you’re sleeping.

In semi-commercial and commercial systems, consider adding a thermostat with a separate remote temperature sensor, with the main thermostat located in a secure location. This system can also be used in combination with many heat-control panels that don’t have inside room temperature sensors, to prevent overheating the building.

For most homes we recommend 1) White-Rodgers thermostats (usually model # 1F80-361 – reliable, simple to operate, and reasonably priced) or Honeywell thermostats (usually the 7400 series).

If you are mechanically inclined and want to install a new “heat only” thermostat on your own (follow installation instructions), you can purchase Honeywell, White-Rodgers, and Emerson thermostats from: H & L heating supply and Amazon.


Save Money on Heating Costs with These Do-It-Yourself Tips

Here are some steps you can take on your own to make sure your heating system is working as efficiently as possible:

  • Repair leaky hot water faucets promptly. Even a small drip wastes gallons.
  • Insulate heating pipes and heating mains in an unfinished basement or unheated crawl space. Foam pipe insulation can be used to insulate domestic hot water pipes to faucets etc. However, heating pipes must be insulated with paper-fiber-coated fiberglass pipe insulation. You may want to ask an expert for help with handling fiberglass insulation, as proper safety precautions must be taken (e.g. wearing a dust mask).
  • Radiator shutters can be opened or closed on baseboard hot water heating, and thermostatic radiator valves can also be installed to obtain even heating.

Renewal—Cohler Fuel Profile

By Stephen Bennett

Cohler Fuel Oil Co. was established 76 years ago and now Allan Cohn, the third generation of his family to run the business, said he is looking to Bioheat as “the gateway to a renewable energy future.”

Cohn said, “I actually trademarked that line.” He had the line included on custom-made decals to promote Bioheat. He trademarked it to keep it away from the natural gas industry, Cohn said. But that doesn’t mean he won’t, in the best interests of the fuel oil industry, share it: “I am happy to share it with anyone in the industry,” Cohn said. “If anyone is interested in using our custom made Bioheat fuel decals for their trucks, vans or boiler labels, they should contact us at CohlerFuelOil@aol.com.”
