Consumer Advice: How much does trench heating cost?

24 May 2023 Cariad Marketing

Trench heating, a discreet type of heating that can be either water or electrical-based, is an innovative solution for managing heating costs. It involves the excavation of small-ish trenches into the floor, with a convector unit securely placed within the trench to generate the necessary heat. Notably, all trench grille heating systems are finished off with the grille itself.

Trench heating demonstrates remarkable adaptability to meet your heating requirements. It can function in conjunction with other heat sources, like radiators, or operate independently as a primary heat source. Furthermore, its versatility becomes evident when considering the space in which it’s installed. This system can be effortlessly integrated into both commercial and domestic buildings, making it an incredibly versatile heating system that can effectively help reduce heating costs.

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

Certainly, like most aspects, determining “how much does heating cost per hour” for your trench grille heating system involves considering various factors. These factors encompass the number of rooms where you plan to install the system, room sizes, your choice of grille type, the dimensions of the grille (length and width), and your preferred heating system model. If you’re considering trench heating for a commercial or office space, it’s essential to account for the installation time, as the area will be unusable during this process.

One significant factor, often of utmost importance, is the type and style of the grille. This element remains visible once the system is operational, making it a key aspect to evaluate. The grille’s aesthetics are just as vital as its functionality. Painted grilles are not recommended due to their limited durability, as the paint tends to chip over time. Therefore, materials like wood, stainless steel, and natural aluminium are the most advisable choices.

Nonetheless, this doesn’t imply a lack of options in terms of aesthetics. You can select the material that best complements your space, and within each material category, there are various finish options available. For instance, among wood types, you can choose from beech, oak, or sapeli, and in the roll-up grilles product line, you’ll find a range of colours like black, gold, and silver. Wooden grilles are an excellent fit for spaces with natural design elements, while metal options are well-suited for corporate or minimalist settings. The grille’s type, width, and length inevitably influence the overall cost of the trench heating system.

To further assist you in determining these costs, you might want to consider using a “heating cost calculator,” which can provide a more precise estimate based on your specific requirements and preferences.

Cost of trench heating

The average price of trench heating will differ greatly due to the high number of variables involved including room size, grille type and size etc. The starting price of trench heating with our product at The Radiator Centre is £646.50 (incl. VAT) but the prices for alternative or replacement grilles are as below, also including VAT:


Roll-Up Double T-Bar

Roll-Up Closed Profile

Natural wood Roll-Up

All of the prices listed above are based on the lowest size we offer on the website (120mm width and 1000mm length). Many of our high quality grilles can also go below or beyond the sizing we offer on our website – simply get in touch with us to get the right size for your requirements.

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!).
