Home Heating Oil Company Serving Northern New Jersey since 1897

We have just celebrated our 100 year anniversary. It was Gerhard Depken and his two sons Frederick and Gerhard Jr. who delivered coal back in 1897. The family tradition continued with Fred Depken Jr., Fred Depken III, and today represented by the fifth generation of Carol and John Depken.

Today represents state-of-the-art home heating oil technology with an old-fashioned service heritage dedicated to keeping your family warm, comfortable and secure. Carol and John are still carrying on the tradition of forward-thinking service. The Depken Family -- it's a 100 year tradition!

New Program -- Upgrade Your Tank

With a new state program, homeowners can apply for grants, which in many cases, fully cover the cost of replacing a non-leaking underground oil tank. If in the process of removing your old tank, a leak is found, money may be available through the NJ Department of Environmental Protection.

How the program works --
The state will give you up $3,000 to help you remove your buried tank and replace it with a modern, environmentally sound tank.

Today's underground tanks are protected against corrosion making them worry free. Above ground options include installation of a modern, clean tank in your basement, backyard, garage or utility room.

As with all government grant programs, there is paperwork to be filled out. will be happy to help you with this.
