Trench heating is a heating system that takes away the need to have standard radiators on the wall. Trenches are dug within the floor and a simple ‘convector unit’ is connected up to the heating system and finished with the one key design feature – the grille. As the system uses natural convection to heat the entire room from floor to ceiling it can be designed to provide heat wherever it is needed in the room.

How does trench heating work?

Benefits Associated with Trench Heating
The size of the trench determines the amount of heat likely to be generated from this form of heating system. The trench’s width and depth determine the size of the heating element that it contains, but also the amount of cooler air that can be drawn in through the grilles warmed and then naturally convected back out into the room. Greater airflow, and consequently heat, can be achieved with the installation of a simple and subtle fan system within the trench.

Trench heating is most commonly installed around the perimeter of the room and the heating grilles can be installed in locations that have been chosen by the customer. In some instances, it can also be fitted upstairs and, because the design of the system can be customised to the preference of each customer, features of the room – such as bay windows – do not pose a problem in terms of installation.

What are the advantages of trench heating?

There are a number of advantages that trench heating has over traditional heating systems. The Radiator Centre’s system is particularly efficient because of the use of a ‘low water’ high heat output heating element. The need to heat minimal amounts of water proves highly effective when used in conjunction with ground source and air source heat pump systems.

Users of trench heating also find that their rooms are also heated evenly which eliminates draughts and cold spots.

Health benefits

Trench heating is particularly suited to homes where one or more of the residents suffer from asthma or other types of allergies. Less air turbulence is created with trench heating than would be created by radiators. This reduces the amount of allergens and dust particles that are found in the air, creating a cleaner environment. Condensation is proves less of an issue with trench heating, making it ideal for use in conservatories or properties that have floor to ceiling windows. Modern properties that may have this style of window are more likely to have trench heating than older properties.
