Trench heating takes away the need to have standard radiators on the wall. It is an ideal way to generate heat when wall space is minimal or you would like a heat curtain to a doorway, so it’s great for cold surfaces, such as outside walls and glazed areas. Trenches are dug within the floor and a simple ‘convector unit’ is connected up to the heating system and finished with the design feature, the grille.
How does trench heating work?
The size of the trench determines the amount of heat generated. The trench’s width and depth determines 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 fan system within the trench.
What are the advantages of trench heating?
Rooms are heated evenly which eliminates draughts and cold spots.
It provides an even, comfortable temperature.
It’s energy efficient, making it economical to run.
Perfect with glass bi-fold walls or large patio windows.
When used against large windows, the heat coming from the trench acts as a kind of ‘air curtain’ which restricts draughts, minimising heat loss and therefore increasing efficiency. It also prevents condensation building on the windows.
Better than radiators for asthma and allergy sufferers as there is less air turbulence, reducing the amount of allergens and dust particles that are found in the air.
Trench heating grilles
The grilles that cover the trench come in different materials – wood or aluminium – and various designs, meaning they can be an integral part of the room’s aesthetics. It also means that whatever floor covering you decide upon – wood, stone, carpet – we’ll have a grille finish to complement it.
NB: The choice of grille finish may determine the final heat output.
Cleaning trench heating trenches
There is one obvious disadvantage of domestic trench heating. Dust! Unfortunately, it does tend to accumulate in the trenches, so you will need to keep on top of the cleaning. However, it will be a relatively straightforward process: you will have a hook to help you remove the grille so you can vacuum the trench, and the grille itself can be cleaned using a damp cloth.
