ckSmithSuperior uses Injection Blending to make precise Bioheat blends

Bioheat, the combination of biodiesel and standard home heating oil, is the safe, energy efficient, and clean future of home heating oil, when blended and delivered properly. Bioheat is part biodiesel, reused plant, cooking, vegetable or other discarded oils, and standard home heating oil in certain percentage blends, like 20% bio and 80% heating oil or B20. Currently ckSmithSuperior delivers a B40 blend, where the fuel you're getting to your home is 40% biodiesel and 60% home heating oil. The key to safe and reliable bioheat is through the blending process where bioheat is created. All home heating oil starts with 5% biodiesel, the remaining 35% is blended into the home heating oil through injection blending. Injection blending is where the biodiesel is injected right into the home heating oil, another blending process is called "splash" blending, where the desired amount of biodiesel is just added to a delivery truck, like adding cream to your coffee in the morning. Splash blending can create uneven levels of bioheat inside the delivery truck, where the top of the truck could be 20% bioheat and the bottom could be 80%. Injection blending allows for precise blending amount all controlled by a computer, below you can find a link to a video that showcases the exact injection blending system ckSmithSuperior uses.

Duncan was great. He noticed my tank's gauge was stuck inoperative and promptly freed it up. That's in addition to his usual excellent service.
