7 March 2023 Trench Grilles
As we navigate through the cost of living crisis, the discussion around heating our homes has heated up (pun intended). Now, more than ever, we’re exploring options for cost-effective and energy-efficient heating solutions in our living spaces, all while trying to stay within our budgets and maintain our comfort. If you’re wondering what trench heating is and how it stacks up against other heating systems like central heating or radiators, let’s delve deeper into the pros and cons of trench heating to understand why it’s worth considering.

Trench Heating is a type of heating in which trenches are dug into the floor and a simple ‘convector unit’ is connected up to the heating system. It’s then finished with the key design feature, which is the grille. Trench heating can either be electrical or water-based. The water pipes or electrical elements are encased in conduit (a tube used to protect and route electrical wiring which can be made of metal, plastic, fibre or fired clay), then run through the trenches that have been dug beneath the floor.
Trench heating can be used as an independent source of heat, or work collaboratively with other sources like underfloor heating or radiators. It’s highly adaptable depending on your specific needs or the space in question. The type of space the system is being installed in is rarely a hindrance as it can be used in both commercial and domestic buildings. This makes it a very versatile method of heating.
Currently, you’ll find the majority of trench heating systems in offices, shops, public buildings and large conservatories. However, it’s now becoming a lot more popular in apartment blocks and new houses. Modern properties that may have a larger or more modern style of windows are more likely to have trench heating than older properties.
However, trench heating systems are not just limited to larger spaces. With smaller spaces there is also the option of the Micro Canal. This is simply a smaller and shallower unit that is only 60mm deep and 140mm wide. With its exceptionally quiet fans and low profile grilles, it works to give you the benefit of the strong heat source without having to dig as deep a trench as you would with the standard trench heating system.
The process starts with drawing cold air through the grilles and into the trench. Once within the trench, the cold air undergoes warming and subsequently rises, creating natural convection to evenly heat the entire room, from floor to ceiling. The system’s design flexibility allows for precise placement of the grilles and heating elements, precisely where and when you need them.
This water-based system can be connected to a standard boiler, but it’s crucial to verify that your boiler possesses the necessary capacity to support it. Each room is equipped with thermostatic valves, ensuring full user control over maintaining the desired temperature.
The trench’s size plays a pivotal role in determining the output of this specific heating system. It directly influences heat production. The trench’s width and depth dictate the heating element’s size, as well as the amount of cool air that can be drawn through the grilles, warmed, and then naturally convected back into the room. For even greater airflow and heat output, a straightforward and unobtrusive fan system can be integrated within the trench.
You will need to decide on whether to make your trench heating system water or electrical based, as well as the size of the trench and unit. Most trench heating systems tend to operate in a similar way, so the internal workings do not differ too much.
However, when choosing the right trench heating system, you should consider the type of grille you desire as this element is the part that will be visible. The different coloured steel or natural woods available can be used as a statement element or blend in seamlessly with the rest of the floor. It’s up to you.
Our linear, stainless steel products are very versatile due to the material they’re made from as well as the simplicity of the aesthetic. Stainless steel will work in both modern and traditional spaces.
The Linear T-bar profile grilles have two material options to choose from: natural aluminium, and satin stainless steel. Both work well for their designed purpose.
Next up on the list are the Natural Wood Roll-Ups. This product line has four natural wood materials to choose from:
Similarly to the Linear T-bar Profile, our Roll-Up Closed Profile product line is offered in both natural aluminium and satin stainless steel. The wonderful part of this product line is that the standard 13mm spacers being made of black PVC; however, the spacers are also available in four alternative colours: grey, beige, light brown and dark brown. This can add a customised feel to your trench grille heating system as you can adapt the aesthetic to best match the space.
Finally, there is the Roll-Up Double T-Bar. Much like the Linear T-bar Profile, the spacers are made of black PVC and are available upon request in the same four alternative colours: grey, beige, light brown and dark brown. The difference between the two being that this product’s spacers are 17mm, rather than 13mm.
The grilles themselves are available in anodized black, which can easily be used to stand out or blend in, depending on the space and your design choices. There is also a gold colour which is a cost-effective alternative to brass and can offer a touch of class. The grilles are also available in natural aluminium, and lastly satin stainless steel for a noticeably higher sheen.
Trench heating systems offer a range of advantages and disadvantages that depend on specific requirements and applications. When considering the use of trench heating in your space, it’s crucial to weigh the trench heating pros and cons to make an informed decision.
There are many advantages to using a trench heating system. Here are just a few of them:
With so many advantages to a trench heating system, you may find it difficult to envisage any disadvantages. And to be fair, there really aren’t any major cons to the trench heating system. However, if you don’t pay attention to the maintenance and cleanliness of the trench space in particular, you could be faced with a build up of dust particles.
However, this issue is easily rectified by simply keeping on top of it! If it’s looking more dusty than it should, a quick clean will bring it back to its impeccable quality and keep any build up of dust and allergens at bay. The cleaning process is made to be fairly straightforward – you’ll be provided with a hook to help remove the grille so you can vacuum the trench, and the grille itself can be cleaned using a damp cloth. Nice and easy!
The main health and safety element you should take into consideration is: can the grille sustain heavy weight or any sudden impact? With the grilles being installed seamlessly into the floor, they will be stood on and walked across on a regular basis. People may also drop a heavy bag or parcel on it, for example, and the last thing you want is for someone to break the grille and fall down into the trench below.
At The Trench Grille Centre, all our grilles are tested for strength and have a manufacturer’s guarantee. This varies from supplier to supplier but it is usually a minimum of 5 years on all manufacturer’s defects.
As mentioned before, you should ensure the trench heating system and grille is regularly cleaned and maintained. This is so that people with respiratory or allergy health issues do not become triggered by dust or allergens being pushed around the room. A health consideration that could be overlooked quite easily, but is entirely necessary.
Finally, there is also the small consideration of the trench being monitored or supervised whilst being cleaned. Due to the grille needing to be removed in order to vacuum the trench, plus the cleaning of the grille itself, there may be a small period of time where there is, to put it simply, a big hole in the floor.
Especially in busy office buildings, this can be a safety concern as if people aren’t being vigilant about where they’re walking. This could cause injury and, in a work situation, open yourself up to compensation claims that could easily be avoided.
Therefore, if for any reason an open trench has to be left momentarily unsupervised, which we really don’t recommend, you should at the very least put up a sign to raise awareness of the hazardous area. If possible, rope off the area entirely to deter people going near it.
Although trench heating can provide numerous advantages, several considerations must be made before making the switch. It is crucial to keep the following in mind:
The building of the trenches and installing the heaters may seem like a daunting process, however it’s not as tricky as you might think. The most complicated part of the installation is the construction of the trench itself. Once this part is out of the way, it’s a simple process.
The grilles might appear to be fairly complicated. However, they’re usually supplied as single roll-up parts. This makes laying them down nice and easy and ensures they can be easily removed to perform general maintenance and cleaning of the trench and element whenever required. It also means they’re easy to replace if you want to change the colour to fit in with a new interior design.
If there are bespoke space requirements like, for example, a bay window with a distinct curve to it, we can commission the manufacturer to build the trench heater that will fit into the space in question.
Our trench heating systems are pressure tested and pre-assembled at the point of manufacture for maximum convenience. So if you’re planning on installing yourself, you shouldn’t hit too many, if any, issues along the way.
