Features of an oil wall heater

Despite the emergence of various fundamentally new equipment, oil heater still remains popular. His admirers often prefer the wall version of the device. What is he good and how does it work?

The principle of operation of the oil cooler

Oil heaters invented a long time ago. Its first options looked simple: a flat heatsink, more like a plate. Modern models have a different shape, providing a large heating surface area and are equipped with many functions. But the principle of the old and new models remained the same.

The device consists of:

• TENA - tubular electric heater;
• hermetic steel or aluminum casing;
• mineral oil, poured into the housing.

When heated, the heating element gives off heat to the oil, which, in turn, heats the surface of the housing.

Modern models are equipped with:

• temperature controllers: manual or automatic;
• fans.

The device is a wall oil heater no different from the floor. Moreover, they are exactly the same.

The only difference is in installation method: the wall-mounted device is attached to the wall by means of brackets, and the floor-mounted one is mounted on the feet-holders. Many manufacturers complement the device with both types of fasteners. So, having bought an oil wall electric heater, You can use it later as a floor option.
