Proof for fuel oil
Reported by Magnetizer Inc. (original letter not on file, so no link): Scarsdale Manor, New York, 1997 — two boilers on #4 and #6 oil showed yearly fuel savings of 17% and 19%, $17,855 a year against $3,716 of equipment, tested with a Bacharach Fyrite II analyzer; with “dirty oil” the boiler efficiency increased instead of decreasing. The full quote is in the dated case studies on the proof page.
Installation
Cable ties are included. Strap the unit around the outside of the line with them — nothing is cut and nothing plugs in. Allow a stabilization period while old deposits clear; no fuel-oil-specific figure is on file.
