With trench heating, the heating element is hidden in a trench under the floor and covered with a grille. Natural convective warm air currents then heat the room evenly, offering an efficient alternative to standard radiators.

If you are renovating your home, you may want to consider replacing your heating system with trench heating as there are a number of advantages.


Trench heating is energy efficient, making it economical to run. The heat is produced underneath the floor and is then distributed evenly throughout the room, meaning there are no cold areas.

Aesthetic and discreet

Modern house designs tend to use a lot of open spaces, often with glass bi-fold walls or large patio windows. Open space and large amounts of glass make the placing of radiators very awkward, a problem that’s easily solved with the understatement of trench heating.

The trench is placed in front of the window, running across its entire length. 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 from building on the windows.

The grilles that cover the trench come in different materials – wood or aluminium – and various designs, meaning they can be part of the room’s aesthetics. It also means that whatever floor covering you decide upon – wood, stone, carpet – there’ll be a grille finish to complement it.

Disadvantages of trench heating

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.
