Trench Heating Questions and Answers
What is Trench Heating?
Trench Heating is method of providing room heat by the installation of Infloor Radiators. These can be Electric or Hydronic Trench Heaters. This website focuses on the Hydronic (Central Heating Fed) Radiators. So basically you hook these Radiators into your existing house heating system.
Why Use Trench Heaters?
Trench Heating is a perfect solution for areas where discrete heating is required or standard wall mounted radiator heating cannot be fitted, possibly due to wall space availability or aesthetic reasons. They are also perfect fro conservatory installations or adjacent to patio doors or large windowed areas as they minimise condensation and reduce cold areas.
Where can I use Trench Heaters?
Trench heating Radiators can be fitted in any room, for Home use it is recommended you fit against a wall, window, door or step as this makes the radiator system blend in more and enhance your decor, although basically there is no limitation as to where it can be fitted. Conservatories, Kitchens, Narrow Rooms, Minimalistic areas are all perfect for Trench Heating.
What Sizes are Available?
There is a vast array of Trench Heating Radiators with single lengths generally maxing out at 4.9 Metres, this is for Transport Reasons and lengths can be joined on site for any length. Various widths and depths are also available and are important considerations with regards to possible BTU outputs for the available length.
What Trench Heater Grilles are available?
Trench Heater Grilles are available in Rigid or Roll up and in a variety of materials including Wood, Aluminium and Steel. They can also have varnish and colour options to suite your decor. Trench Heater Designer Grille Patternation is also available.
Are Trench Heaters only for Domestic Home Use?
No, While Domestic Trench Heating is a perfect solution for home heating, Trench Heaters are also utilised in Office and Showroom areas, basically any commercial or industrial heating application can be served by Trench Heating.
Can Trench Heaters be used on ground or air source heat pumps?
Yes, the only consideration is the BTU output will vary according to the Delta T of the Heating system, basically the lower the water temperature the lower the Radiator BTU heat output achievable.
Do Trench Heaters use Electrical Supplies?
Standard Hydronic Trench Heaters generally need no electric feed, however some models are Fan Assisted which basically means they draw air through the heat exchanger and expel it into the room using a low noise fan. These require either a 230VAC Supply or an External control supply usually 12 or 24V.
Why would I use a Fan Assisted Trench Heater?
The utilisation of a fan significantly increases the BTU output for the same size pure hydronic trench heater radiator. This can be useful where space is limited, greater outputs are required or water temperature is lower for example with ground source heat pump systems.
Why are Trench Heaters particularly suited to large windowed areas?
By Design Trench Heaters can be unobtrusively fitted along the length of a windowed or glass door area, these areas are renowned for condensation formation or for cool area creation, Trench Heating Radiators fitted along this length produces a heat curtain which does not allow condensation to form and also produces an insulated barrier which stabilises the areas temperature.
How do I calculate my Trench Heating requirements?
First you need to do a Heat Loss Calculation as you would for any Hydronic Radiator Installation. Then if using alongside traditional wall mounted radiators take these into consideration. Then simply look to achieve these outputs with your combined Trench Heating.

Where can I buy Trench Heaters Online?
Trench Heaters can be bought online at websites such as Trenchstyle.
What Valving do I need for Trench Heating?
View Trench Heaters as normal radiators, you can fit manually controlled or thermostatically controlled valves (TRV). Due to the nature of an infloor radiator we recommend the sensing head is out with the Trench itself to avoid localised heat impacting the sensing. Generally a remote adjustment connects to the valve head via a thin bore capillary tube. Alternatively you can fit manual lockshields throttling back as required and allowing a room thermostat to manage the flow through central heating water temperature bu switching the boiler on or off or controls at a remote manifold.
