Trench heating for large glazed areas

Trench heating for large glazed areas

Trench heating systems by Dunham-Bush provide an effective solution for countering drafts and condensation in buildings with large glazed areas.

The appropriate heating and cooling systems can contribution to both the efficiency and the environmental comfort of a building.

A major consideration when selecting heat emitters for a building must be the variable occupancy, building usage, buildings orientation and the possibility of having four seasons’ weather in one day, which is common in the UK climate.

These considerations become even more important in buildings with large glazed areas, where solar gains and losses are common.

Heat emitters that respond quickly to these changes can increase the seasonal efficiency of a building substantially, reduce CO2 and NOx emissions and increase the wellbeing of its occupants.

Trench Heating Systems provide a highly effective solution for countering down draughts on cold surfaces, helping to prevent unsightly condensation on large glazed areas and outside walls.

Ideal for, a variety of commercial and institutional buildings, for example, high-rise offices, car showrooms, airports, universities and exhibition centres.

Natural convection heating trench systems have no moving parts and are effectively silent. Low temperature hot water is the most commonly used heating medium, however electric trench emitters are available for certain applications.

Fan assisted trench or forced convection systems are a compact alternative when higher outputs are required and space is restricted. In addition, fan assisted Trench emitters can incorporate a cooling coil and drip tray, typically available as either a 2-pipe or 4-pipe application, similar to fan coil unit.

Natural convection units require little if any maintenance, whilst fan assisted units are readily accessible for routine maintenance with no need to consider the dangers of working at heights.

Trench heating systems using low temperature hot water have inherent low water content, making responsive to the solar heating gain experienced in large glazed facades.

Fan-assisted trench units with cooling coils can be used to offset these solar gains still further during the summer months, again with no additional grilles or systems, other than making chilled water available.

Trench heaters can be modified to integrate with a ventilation system, thus allowing primary or fresh air to be distributed with no additional floor grilles being required.

Dunham-Bush manufacture standard and bespoke systems to the client’s dimensions and outputs, to suit all applications. Floor grille bars can be finished in stainless steel, anodised aluminium, bespoke cast iron and wood from sustainable sources and can be selected to meet any architectural brief.
