Six Ways to Prevent Heating Oil Gelling
Having an outdoor heating oil tank in a climate like ours can be problematic, as you may have experienced in recent years here in the Hudson Valley.
Mostly, that’s because when heating oil drops below a certain temperature, it “gels” – that is, it freezes into a thick, viscous sludge (oil doesn’t reach a solid state when it freezes, the way water does).
Heating oil tank — When oil gels inside your heating oil tank, the sludge settles to the bottom, shrinking available space and leaving behind less burnable oil.
Heating oil lines — Gelled oil builds on heating oil line walls, narrowing the passage way like a clogged artery. With less fuel reaching the igniter, your heating efficiency will suffer, leading to higher energy bills.
Atomizing nozzle — The atomizing nozzle turns liquid heating oil into a vapor that can be burned inside your heating equipment – but gelled fuel can block that nozzle, meaning that less oil will get through to convert to heat. Once again, heating efficiency suffers, leading to higher bills for you and, eventually, repairs for your heating equipment.
Fuel filter — As gelled oil is forced through the filter, it clogs quickly and needs more frequent replacement.
