Blue Diamond Fuel

Over time, the business evolved from supplying ice and coal to providing kerosene and then fuel oil as heating technology advanced. The introduction of oil burners in the early 20th century led to the creation of Blue Diamond Fuel Oil as a home heating provider.

Growth and adaptation

• In the late 1940s and 1950s, a new generation of the family joined the company and expanded services, offering more modern heating equipment and broader coverage beyond Sunset Park.
• Following the 1977 oil embargo, Blue Diamond expanded into natural gas expertise, helping customers install and service natural gas heating systems.
• With energy market deregulation, Blue Diamond began offering natural gas supply at potential savings compared to large utility companies.
• In 2014, the company relocated to a state-of-the-art facility in Bay Ridge, Brooklyn, designed to enhance dispatch and customer service operations.

Year-round conservation tips

Examples of year-round recommendations include:

• Install a programmable thermostat to reduce energy use when heating or cooling is not needed.
• Use compact fluorescent or other high-efficiency lighting, which can last longer and use significantly less energy than standard bulbs.
• Take showers instead of baths to reduce hot water use.
• Air-dry dishes instead of using a dishwasher's heated drying cycle.
• Choose ENERGY STAR®-rated appliances when purchasing new equipment.
• Install water-conserving fixtures, such as low-flow showerheads, faucets and toilets.
• Avoid leaving refrigerator and oven doors open longer than necessary.

Cold-weather conservation tips

To reduce heating costs and improve comfort during the heating season, Blue Diamond suggests:

• Upgrading to a high-efficiency oil-fired water heater.
• Upgrading to a modern oil burner, which can reduce fuel costs compared to older equipment.
• Sealing gaps at doors and thresholds and repairing weather stripping and caulking.
• Ensuring adequate insulation, such as at least six inches of good thermal insulation in ceilings where recommended.
• Avoiding space heaters where possible, due to safety concerns and high operating cost.
• Wrapping hot water pipes and considering a water heater blanket to reduce heat loss.

Warm-weather conservation tips

To save energy in warmer months, recommendations include:

• Keeping furniture clear of air conditioning vents.
• Cooking outdoors on a grill when practical to keep heat out of the home.
• Setting air conditioning thermostats higher (for example, around 78°F or higher when appropriate) or using programmable settings.
• Installing reflective window coatings and keeping blinds or curtains closed during hot, sunny periods.
• Cleaning or changing air conditioner filters regularly during the cooling season.
• Opening windows on cooler days or nights when outdoor temperatures are lower than indoors.
