Trench heating is a stylish way to heat a room with large expanses of glass or little wall space for panels. A trench convector is covered with a grill that can be designed to match your floor covering or taste. They work by heating the cold air that falls from glazing into the trench. As with all hydronic heating there is no blown air so it makes for the most comfortable method of heating your home.
What is Trench Heating?
Trench heating is where we install a hydronic panel system within a trench in the subfloor with a grill over the top that matches into your flooring. It is the preferred method of heating a room with large expanses of glazing, little wall space or if panels are not desired. The pipes are laid from the boiler through the slab or sub floor to the end of the trench. Trench heaters can be purchased as an off the shelf product or can be boxed out by the builder. The hot water heats a panel that is in one side of the trench so as cold air falls off of the glazing into the trench it is then heated and rises.
The grill that covers the trench can be a standard off the shelf product or a bespoke product that is made to match your taste or flooring.
How long does it take to heat?
Trench heating is highly responsive. While controlled by a thermostatic controller so that it maintains a comfortable temperature, when turned on you’ll notice that your home will be warm within half an hour. As they are part of a hydronic system, they are incredibly efficient as water is a great conductor of heat energy.
Trench Heating has 3 main components.
- The Trench Box
- The Convector Element
- The Grill
Trench Boxes are manufactured in a range of fixed sizes and are finished with 5mm of insulating foam to the outside.
There are two main depths
305mm or 110mm
The shallower 110mm has a far lower kW out put per meter but maybe the best option if you are building with a slab.
The Convector Element
This Element is where the hot water passes through to create the convective heat process. These also come in a range of sizes to suit different sizes rooms and meet kW requirements.
Grills are made from a range of materials with a wide variety of finishes.
Aluminium Grills can be finished in a range of colours or metallic looks.
Timber Grills can be matched or even made from your timber flooring, as well as being stained.
