The KWO 500 waste oil-fired boiler can service commercial buildings requiring up to 400,000 net BTUs of energy for hydronic heating. Waste oil-fired boilers have the ability to recycle used motor and hydraulic oil, vegetable oil and other petroleum products and to recover "free" energy in the process. Onsite recycling also minimizes the cost of disposal and reduces the chance of waste oil contamination in the environment.
