Trench Heating Article

The bitterly cold weather in Russia served as an incentive for the Prussian-born Russian, Franz San Galli, to invent the first radiator between 1855 and 1857. Radiators have since been used to heat up homes and commercial buildings such as hotels, restaurants and offices. Radiators are finned devices that are used to exchange heat, transferring cold air, using thermal energy through the process of convection to an open space or room as hot air and because the major mode or transfer of heat is convection, they can also be called convectors. Basically, they are called heat exchangers. Types of radiators are the wall-mounted radiators and the trench heating systems.

The trench heating system follows the mechanism of exchange through the Grilles, important features on a trench heater. A trench heater is an insulated, steel casing containing a convector unit. The trench heating system is rectangular in shape. Its width and length and depth determine heat output through the grilles. Increases in surface area invariably increases heat output. Trench heating systems use either water or electricity as their source. The encased heating element, an aluminium finned copper tube, is kept inside a trench beneath  ground level. The grilles take in cold air and it is heated up through natural convection made possible by the water or electrical heating system and the air, already hot, rises through the grilles and spreads through the room.

Trench Heating can be fan assisted to increase the BTU for the same size unit. Jaga’s fan assisted Trench Radiators are called DBE or Dynamic Boost Effect Trench Heaters.

The trench heating system provides even distribution of heat along the edges of rooms. This even distribution prevents cold spots and draughts. It heats up fast and is a very efficient heating system because it uses “low water” heat high heat output elements. They are space saving unlike the wall-mounted radiators and are unobtrusive. The trench heater can be placed anywhere in the home since they do not obstruct movement, they are beneath the ground. They are commonly used now in homes that have glazed façades, offices, beneath patio doors or even under a flight of stairs.

 The grilles of trench heaters come in different finishing and can be customised to the customer’s taste, hence, they add to the overall beauty of the room. They have health benefits also in that cause lesser air turbulence and reduce the circulation of allergens and dust particles.

They can be controlled using thermostats or smart control.

The performance of trench heating systems can be determined using the EN 16430 test procedure which can not only detect performance rate but also noise and pressure.
