Consumer Advice: How much does trench heating cost?

24 May 2023 Cariad Marketing

Trench Heating is a discreet type of heating which is either water or electrical based and involves small-ish trenches being dug into the floor. A convector unit is then secured into the trench which will be responsible for creating the heat. Finally, it’s finished off with the notable characteristic of all trench grille heating, the grille itself.

Trench heating is very adaptable depending on your heating requirements. It can work collaboratively with other sources of manufactured heat, such as radiators, or be used independently as a heat source. It also demonstrates its adaptability depending on the space it’s being installed in. The system can be installed with ease in both commercial and domestic buildings making it incredibly versatile as a heating system.

A trench heating system removes the need for traditional radiators and central heating. It frees up your walls where a radiator would normally be fitted and utilises space (under the floors) that otherwise goes unused and unnoticed.

Factors affecting trench heating system cost

Of course, like with most things, there are numerous factors that will affect the price of your trench grille heating system. Factors such as: the number of rooms you wish to install the system into, the size of the rooms, which type of grille you choose, the length and width of the grille, and which particular type of system you wish to use. If you’re looking at trench heating in a commercial or office space, you should also consider the time it will take to install as the space will be unusable during the installation process.

The factor that will perhaps be taken most into consideration is the type and style of grille. This is because it is the only element that will remain visible when the system is up and running. Therefore the functionality isn’t the only element to consider – the aesthetics of the grille is also a factor to contemplate. Painted grilles are not recommended due to the lack of durability, as the paint tends to chip away over time. Therefore, materials such as wood, stainless steel and natural aluminium are the best options to choose from.

This doesn’t mean, however, that you don’t have much choice when it comes to the aesthetics. You can choose the material that best fits your space and there are different finish options within the materials category. There are various wood types to choose from such as beech, oak and sapeli, and there are multiple colour options in the roll up grilles product line such as black, gold, and silver. A wooden grille would fit best in a space with natural design elements, whereas the metal options would work well in corporate or minimalist settings. The type, width and length of the grilles will inevitably affect the overall price of the trench heating system.

Cost comparison with alternative heating systems

In the current cost of living crisis, we’re all doing our best to cut costs where we can. You may therefore want to try and find the cheapest way to heat your house or office space. It’s completely understandable as utility bills have been at an all time high this winter and we’ve all felt the pinch.

Trench heating is an excellent investment. There will, of course, be the initial cost of purchase and installation of the system and grille itself. But once it’s installed you will see a very worthy return on investment quite quickly because the system’s energy efficiency makes it incredibly economical to run. The system works rapidly to heat the room using a very small amount of water (in the water based systems) to give a high heat output. This means the system will produce the same amount of heat as an average radiator but only using a fraction of the energy because the amount of water you’re heating is so much smaller, resulting in clear energy savings.

As the trenches are strategically installed around the perimeter of the room, the system can also heat a room much quicker and easier than a radiator can. A radiator will produce heat only from the spot it resides in, leaving the areas of the room furthest from the radiator much cooler, and the room will feel uneven in terms of warmth. Whereas, with the trench heating system surrounding the room, heat is pumped around the entire circumference of it with speed and efficiency. This means that the space will have an even distribution of heat, allowing you to enjoy the comfort of a cosy, warm room.

Another way in which this innovative system has an advantage over alternative heating solutions is that it’s especially good at heating areas that typically allow heat to escape, such as large windows and doors. It works diligently to combat and eliminate draughts that reduce the overall warmth in the room and which would otherwise be the main cause in driving up your central heating bill.

When compared to plug in electrical heaters, there’s a clear winner. A plug in electrical heater can seem like a quick and cheap way to provide some heat into your home and in terms of the initial price, this may be a valid point. However electrical plug in heaters use a huge amount of electricity and prove inefficient in converting the energy it’s using into heat. Therefore, although it may be cheap to initially buy, this isn’t where the spending stops and you will see the evidence of this in your energy bill. There’s also the fact that it will only be heating a small area, meaning you’ll be spending a fair amount without much reward (unless you’re standing next to it!).
