Trench Heating

Discrete under floor system for combating heat losses at glazed elevations


Trench Heating systems are applicable to a range of sectors, particularly commercial buildings, education facilities, healthcare institutions and transport hubs. Demand normally stems from having a glazed facade, however recessed trench heating maximises floor space and removes wall-mounted systems, which may not fit with the aesthetics of a project.



Under floor installation frees up valuable teaching space and removes the requirements for a wall mounted systems. This is particularly relevant at glazed perimeters where wall mounted systems are not feasible. Trench Heating systems are ideal for preventing condensation and cold down drafts. Trench Heating systems are straightforward to install and require minimal maintenance. Once in place only the grilles, which are available in a range sizes and materials, are visible. Trench Heating systems can be found in schools, colleges, academies, universities and other third level institutions.


Public Buildings/Healthcare/Transport/Leisure/Residential 

Trench Heating systems offer a discrete heating solution, which is suitable for a range of  buildings including office buildings, hospitals, transport hubs, libraries, prisons, police and fire stations, leisure and community centres and also in residential developments.

Trench Heating systems are the ideal choice for eliminating condensation and cold down draughts at glazed perimeters. They can be specified as a primary or secondary heat source and are available with a range of different grilles.

Locating heating units below the floor level frees up space and reduces the opportunity for damage, particularly in high foot-fall areas. Trench Heating systems feature few moving parts, resulting in reduced maintenance requirements and costs. This can be particularly relevant in buildings which have extended opening hours and operate six or seven days a week.

Hydronic trench heating works using natural convection and without the use of electrically driven motors. This reduces the amount of energy consumed by the systems, leading to lower EPC (Energy Performance Certificate) and DEC (Display Energy Certificates) ratings.



Trench Heating is most often found in commercial office environments which feature curtain wall glazing. Recessed trench heating does not infringe on full height wall to floor fenestration and prevents condensation and cold down draughts.

Recessed Trench Heating maximised the available floor space and the way in which
it is used. Further information on maximising the net internal area can be found by clicking here.

Trench Heating can be specified as a primary or secondary heat source and is available with a range of different grilles to meet project specific aesthetic demands.
