A different way to compare
Sales of 12 volt oil burner systems have been reasonably successful over the last 18 years. In general, the initial cost of this 12 volt burner equipment, in comparison with the 115 volt oil burner systems, has been about 5% lower than the SS, SC, and the CP Heatlink models that use the 115 volt burners with self contained 115 volt generator. The generator and drive parts add to the cost.
Unfortunately, some 12-volt users have encountered unexpected repair costs eroding this initial 5% savings. Costs can include igniter repairs, insulation re-wrap, charging system maintenance problems or application miss-steps. The additional maintenance requirements and potential costs do not always get fully communicated or recognized during the initial product offering. In some markets they are inadvertently overlooked.
Consider this comparison:
Much like the perceived lower cost benefits of an OFF grid solar powered electrical generating system, solar 12 volt systems require significant attention and care to keep them in top shape. Battery quality, charging system efficiency, voltage regulation, corrosion control and the man's service proficiency all must be at top notch levels to insure satisfactory long term operation of the solar panel system. When it's maintained, a return on the investment results. Continuing the illustration, with the 115 Volt AC system, or an ON grid electrical system powering a household, several critical maintenance requirements and costs are eliminated: corrosion control, battery quality, charging system challenges, and man's proficiency level when operating or maintaining the 115 volt systems are no longer critical factors. One simply needs to turn the light switch on and it works.
When a combination of factors such as limited service proficiency, long 8 to 10 hour operation days, and exposure to severe environmental conditions occur, the challenges are frequently better met by the more forgiving 115 volt burner systems. Attention to a regular maintenance schedule is still required, but the schedule is less demanding that the one for the 12 volt systems.
Fortunately there is better news for those considering purchase or who already own 12 volt burner systems. Significant improvements have been made over the last 2 years that include interrupted ignition igniters (they run cooler and demand less power), double duty grounding, high amp chargers, and automatic flame monitor options. Hydro Tek’s guiding principles include continued research towards value & savings in its designs, and integrity in its presentations. As an equipment provider we may find the solar “off grid/ on grid” illustration, helpful when presenting the 12 volt and 115 volt burner equipment options and the advantages of each system type
