The Gateway to a Renewable Energy Future®

During Covid-19

Dear Valued Customer,                                                                           

With the crisis of the COVID-19 virus, we hope that you and your family are safe and doing well.  Our deepest condolences to all who have lost loved ones during these difficult times.  

We would like to thank you for putting your trust in us, and for letting us serve you.  Now would be the perfect time to go on a level-payment “budget plan”.  Since 80% or more of your yearly fuel bills come in just 5 months, spreading your payments over 12 months’ time, makes your monthly payments much more manageable and predictable. Please call or email our office this month.

The Bioheat® fuel we deliver provides efficient heat and hot water that is cleaner, safer, and better for the environment.  Our new additional name “Cohler BioEnergy Fuel Co.”, reflects our direction into the future with renewable blended fuels.  Nothing at all has changed with our company, our quality, the ownership, or staff. 

Keep your boiler running reliably and as efficiently as possible with our full-value and FREE yearly tune-up.  Why wait for a boiler breakdown in the middle of the winter?  Our goal is to avoid future problems by doing important maintenance and check-ups now, so that we can keep you warm and safe all season long. 

Landlords: Reduce your violation aggravations, while we help you save money with lower fuel consumption.

Please Call Us This Month to Schedule Your Free “Burner Tune-Up”

**(Due to safety concerns with the COVID-19 virus situation, please ensure that you, your family, or employees, maintain at least 6 feet of social distance from our service techs.  We will be wearing masks and gloves, and ask that you also wear a mask, for your safety and ours.)**

A reliable chimney cleaner may also be needed at this time of year to clean your chimney bottom, and the inside of the boiler as well.  Get an estimate and remember that cleaning the chimney from the roof down, chimney caps, and liners, are not usually necessary.

Chimney companies that we have used, and have been satisfied with, are “Be Safe” (“Steve”) (1-4 family homes, only through September) 347-794-8593, or “Ray and Sons” 646-436-0278.  For properties larger than 12 units, we have used “Consolidated” 718-931-8300.

If there is any way that we can better serve you, or if you have any questions, please call us anytime.  Stay safe, be well, and best wishes for a pleasant summer.

Testimonial from C.R.

“I want to thank you for the extraordinary action on your part and your employees on my behalf on my dilemma of 01/10/15. When your mechanic Steve came in after the delivery we were further amazed. My family were freezing but shortly after your men took action, the burner was running and the radiators started to warm up. Needless to say we all were able to sleep comfortably.”   — C.R.  (Marine Park, Brooklyn)

Testimonial from L.P.

“As a landlord, I have plenty of things to worry about with my buildings and tenants, but having Cohler as my oil company, I can be sure that all my building’s heating needs are covered and have one less thing to worry about. My grandfather has been dealing with this company forever and now I can see why- they are no-nonsense, honest, always do the right job and actually care for the well-being of their customers. There’s a lot to be said for the level of comfort I have knowing that Cohler is taking care of my buildings.”   — L.P.  (Boro Park, Brooklyn)

Testimonial from A.Z.

“Just want to salute Cohler Fuel Oil, the oil company that has kept our family warm for over 10 years. This is a family run company, and as such appreciates and cherishes courteous relationships with their customers. Cohler has always been looking out for us with only our best financial and comfort interests in mind.

The other night, we ran out of oil. We called Cohler a bit too late, as the trucks were already parked for the night. But this didn’t stop Ben from appearing at our door, with two brand-new electric heaters in his hands. Just to ascertain that we are comfortable through the night until oil is delivered early the next morning. Only Cohler…Professional, yet personal, with a smile.

Thank you, Cohler, a company that we can trust, and rely upon for the comfort
and warmth in our home!”

Testimonial from T.P.

“My family and I have been a customer of Cohler Fuel for over twenty years. Need I say more…but I will. Cohler’s service technicians are professional and knowledgeable people. They respond to any situation in a timely manner. They assess the problem and correct what needs to be done. They are reliable and trustworthy. I have left them alone in my home and have never had any issues whatsoever. They are also very neat when they do their work. The office staff are courteous and professional, always making sure that a technician responds and even lets you know an approximate time they will be arriving. They even respond to you after business hours. The owner’s of the business are also out in the field so they know what is going on and what a customer needs. They are true gentlemen, as well as experienced technicians themselves. I highly recommend them as your fuel oil provider.”   — T.P.  (New York City)

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.
