Engine oil heater attached to the engine's oil pan with magnets. Engine oil heater inserted into the dipstick tube. In-line coolant heaters, which are installed into a radiator hose to warm the coolant (sometimes with a circulation pump to increase its effectiveness). Electric blankets that are laid over the top of the engine.
An oil heater, also known as an oil-filled heater, oil-filled radiator, or column heater, is a common form of convection heater used in domestic heating. Although filled with oil , it is electrically heated and does not involve burning any oil fuel ; the oil is used as a heat reservoir (buffer).
Thermic Fluid Heater A Thermic Fluid Heater (TFH), [1] also known as a thermal oil heater, is a device used for indirect heat transfer through a thermic fluid. It heats the fluid to a desired temperature and then transfers that heat to various processes without any direct contact between the heating source and the product.
Diagram of natural draft gas furnace, early 20th century. The first category of furnaces is natural draft, atmospheric burner furnaces. These furnaces consisted of cast-iron or riveted-steel heat exchangers built within an outer shell of brick, masonry, or steel. The heat exchangers were vented through brick or masonry chimneys.
A convection heater, also known as a convector heater, is a type of heater that utilizes convection currents [1] to heat and circulate air. These currents move through the appliance and across its heating element, [ 2 ] using thermal conduction [ 3 ] to warm the air and decrease its density relative to colder air, causing it to rise.

In theory, tankless heaters can always be somewhat more efficient than storage tank water heaters. In both kinds of installation (centralized and POU), the absence of a tank saves energy compared to conventional tank-type water heaters, which have to reheat the water in the tank as it cools off while waiting for use (this is called "standby loss").
