Trench Heaters – Advanced Discrete Heating System
Trench Heating is basically an in floor radiator system, cool air enters one side of the Trench Heater and warm air exits the other side. Generally the airflow is facilitated by the rise of warm air creating a lower pressure and drawing in the cooler air. Although some systems also incorporate ultra quiet BTU boosting fan assist units.
The Trench Heater will provide a heat curtain and as such these radiators which are also known as canal or perimeter heating are perfect adjacent to glazed facades or patio door, areas where condensation or cool areas can exist.
Trench Heater Radiators work in the same way as wall mounted radiators with central heating water passing through which is controlled by manual or thermostatic valves or zone control systems. Generally thermostats are best mounted remote from the Trench Heaters to avoid localised impact from the heater itself.
Trench Heating can also be used with heat pumps although it is recommended that Fan Assist is used to increase the BTU outputs.
Trench Heating can be used as whole room heating, supplementary heating or targeted area heating, it is extremely flexible in it application and can make your room more minimalistic while maintaining its warmth and functionality.
There are a number of Trench Heating Manufacturers in the UK and Europe but with only a few offering extended warranty on the heat exchanger which is a critical part of this central heating system.
Jaga Heating offer a thirty year Warranty on their Copper and Aluminium Heat Exchangers, which is market leading, however you will pay a premium for Jaga Trench Heating quality as these are made to order generally with a 4 week lead time.
Trench Heating outputs will generally depend on the space within the trench heater body, so effectively the longer, wider and deeper your home, office etc can accept the greater the output can be BTU produced. With the only variation being the fan assist which can improve heat outputs by 20 – 50%.
To complement your decor Premium Manufacturers such as Jaga provide a multitude of options in respect to Grille Type and Material, wood both varnished and natural are a popular Trench heating Grille option as is Natural Aluminium, Stainless steel is generally a more expensive option but looks fantastic. Grilles come in two levels of flexibility Rigid and Roll Up, rigid trench heater grilles lift off in a single, joined or separate solid pieces and generally there is no movement under foot, roll up are easier to remove for cleaning and trench heater maintenance. To increase your options colours of grille can also be specified to most Ral colours. Sometimes the choice is whether to contrast or complement the grilles with your existing decor or flooring which is generally a personal choice.
In summary for a Home addition of Trench Heating I would consider the following:
BTU Heat output Required – When calculated we need to decide how this can be achieved, one or more Trench heaters? Generally a larger room can achieve a more balanced heating gradiant if two or more heating sources are used in opposing areas. Remember Depth is out of site, the deeper generally the greater the BTU you can achieve, you would generally have an approximate length available so Trench Heater width then becomes important, personally for a home installation which forms part of a walking path such as Bifold Doors, Patio Doors, Doorway, Steps etc I would suggest up to a 26cm width would be appropriate, if not in a walkway up to 42cm would be appropriate eg against a wall. Also remember you can increase your heating output for the same size unit by 20-40% minimum by adding a Fan Assist BTU Boost.
DESIGN – What do I want my decor to look like, is the Trench Heating to be a hidden unit in which case you would blend the grille material and colour with the existing floor, perhaps looking to place in a non walking path. Am I happy to retain my wall space and showcase my innovative heating system then select a Grille which contrasts and forms a floor based feature of heating functionality.
