We are excited to introduce a new preheater design for our EnergyLogic Waste Oil Heaters and Boilers.
New Preheater Design
EnergyLogic has developed a new oil preheater design that uses a flat, finned extrusion to provide surface area for heat transfer. The main advantage of the new design is that the electrical components (heaters and thermostats) are on the outside. This allows them to be easily removed, so the extrusion and cover can be cleaned in a parts washer and the electrical components can be easily replaced if one fails, rather than replacing the whole preheater.
We have limited tube Preheaters available for parts purchase. Once inventory is depleted, there is a Flat Preheater Retrofit Kit available to purchase that will allow you to convert to the updated preheater.
New Burner assemblies will ship to you with the new style preheater. Typically, installation of the new style unit doesn’t require any modifications to your furnace or boiler, although careful attention must be paid to the primary fuel line to ensure a good, free-flowing fuel supply.
