Complete with our patented TankSaver® technology, an exclusive innovation that impedes corrosion and extends tank life, John Wood oil-fired water heaters also feature a universal mounting design that fits most burners. Its ceramic fiber combustion chamber maximizes heat retention, while its immersion-type aquastat allows for precise water temperature control.

Our oil-fired water heaters are also available in center and rear flue (on US models only), as well as a direct vent model that is suitable for combination potable water and space heating.
