Jaga trench heating article


A radiator is defined as any set of various devices (as a series of pipe for water or tunes for electric conduit) for transferring heat from a fluid within to an area or object outside. Radiators are simply used to exchange heat, usually taking in colder air and giving out hotter one. The mode of transfer is convection and so are sometimes called convectors. Convectors describe a set of devices whose source of heat is not directly exposed.  It took two years, 1855-1857, for Franz San Galli, a Prussian born Russian to invent the heating radiator. The radiators have since served as heat providers in homes and commercial buildings such as offices and restaurants. The uses and importance of a heat radiator cannot be over emphasised especially in cold places like Russia (and the UK!).

While wall mounted radiators have been in use for decades and have made their users happy, Trench heaters are a more recent heating system with more to offer. Trench heating systems operate based on water or electricity using convection as a medium of heat transfer and so can be used at any time. They are long, rectangular casings, insulated with steel containing a convector unit. They are fitted beneath the ground in already dug trenches.  The trench heater has an important part called the grille. This allows the passage of hot and cold air in and out of the system. Multiple grilles mean increased surface area for air passage. The grilles have the tendency to accumulate dust particles and dirt and so it is advised that the grilles be cleaned periodically so that their function will not be impaired. In trench heaters, subtle fans have been built to ensure better airflow.


The water-based system works through a conventional boiler with enough capacity. Water pipes are encased in conduit and run beneath the ground in the constructed trench.


The cold air from the room is drawn into the system via the grilles, warmed by the convector unit and made to rise out of the system via the grilles again to heat up the room. With Trench heating, there is even distribution of heat across space thereby preventing cold spots or draughts unlike in wall mounted radiators where hot air might be in specific spots such as close to the ceiling causing heat wastage. The trench heating system uses a “low water” high heat output method which makes it very efficient and economical. Also, there is reduced the risk of condensation where glazed façades or large areas of glass are situated. Room thermostats, Thermostatic Radiator Valves (TRVs) are used to control heat output. Smart control is a recent, easy way of controlling output.
