Unlike gaseous fuels, Bioheating oil will not support combustion (flame) unless the temperature is about 140 degrees Fahrenheit. There is not enough fuel vapor to cause an explosion or fire.

Stem Brothers was founded in Milford, NJ, more than 60 years ago but has grown to serve all of Hunterdon County, including the county seat, Flemington, NJ. In addition to Flemington and Raritan Township we reach all other Hunterdon County communities as well as parts of Warren County, including Alpha and Phillipsburg. We also deliver and service customers in parts of Bucks County, Pennsylvania.

Without doubt our quickest and greatest growth has been in the Flemington and Raritan Township area. We enjoy continued growth throughout our region but have found Flemington to be especially receptive to our quality service and superior products.

Until recently the quick and simple answer would have been heating oil, propane, diesel, kerosene and gasoline. Recently we became the first and only distributor in our marketplace to include Bioheating oil and biodiesel to our product list. In fact, we have completely replaced heating oil and diesel with Bioheating oil and biodiesel.

Yes, there are many benefits. Some would argue that the greatest benefit from using Bioheating oil and biodiesel is the reduced carbon impact upon our environment. We think that’s very important too, but we also know there are tangible benefits to our customers. Cleaner burning fuel, such as Bioheating oil, equates to improved efficiency, as well as a continuously maintained clean fuel system operation. Fuel pumps, whether for heating oil or diesel, benefit from the added lubricity of Bioheating oil and biodiesel, not to mention it is a renewable product that reduces our dependency on foreign oil.

Only at Stem Brothers, Inc., if you are within our service area.

While it is a superior product the answer is Stem Brothers does not charge additional for Bioheating oil or biodiesel. Retail pricing is primarily a function of competition and Stem Brothers is favorably positioned when it comes to retail pricing for all of our products. That would include Bioheating oil, biodiesel, kerosene, propane and gasoline.

We introduced a new CAP Price Protection program last season and will repeat it in the 2011-2012 heating season. The CAP program provides our customer the opportunity to purchase price protection to “CAP” the price of heating oil or propane for the coming heating season. It’s like buying peace of mind knowing that the amount you’ve budgeted for energy is not going to exceed that price.

We also have an EZ Pay budget plan and a CAP budget plan; customers pay a monthly price based on previous usage. In this manner the customer pays a little each month instead of facing a larger invoice upon delivery of their bio heating oil or propane.
