TRENCH CONVECTORS · HEATING, COOLING, VENTILATION · INVISIBLE
In-floor convectors for floor-to-ceiling glazing, open-plan rooms, and heritage interiors where wall space is precious. Heat from below, cool from above the dew point, ventilate on demand — all from a slot in the floor.

CLIMA CANAL MODELS ADD LIGHT COOLING IN SUMMER
Many grille finishes
WOOD · ALUMINIUM · BRASS · MATT BLACK
A long, slim metal tray is set into the floor — usually along the bottom of a glass wall or under floor-to-ceiling windows. The heating element sits inside the tray. A grille covers the top, flush with the floor.
Hot water from your boiler or heat pump flows through a thin aluminium-and-copper coil inside the tray. The coil warms up. Warm air rises through the grille and along the glass.
When the inside of a big glass window gets cold, air falls down the glass, creating a chilly draught at floor level. A Trench convector under the window pushes warm air up against the glass, blocking the draught and stopping condensation.
All you see from above is the grille — available in wood, aluminium, brass, or matt black to match your floor. Walk over it, place furniture near it, no one notices it's there.
Low-H2O technology means the Trench warms up quickly at lower water temperatures (30–45°C) — the range a heat pump runs most efficiently. Same principle as Strada and Guardian LST.
Clima Canal models add a small fan inside the trench. When chilled water flows in summer (from a reversible heat pump), the fan blows cool air up out of the grille — gentle cooling without an AC unit on the wall.
Same simple radiator controls as any wet-system radiator, plus optional fan control for Clima Canal (cooling) and Hybrid Canal (boost) models.
Standard TRV (default)
Each trench has a thermostatic valve dial — same as a wall radiator. Turn it up for warmer, down for cooler. The valve sits inside the recess for safety and tidiness.
Smart TRV (optional)
Replace the standard dial with a smart TRV (Tado, Drayton Wiser, Honeywell evohome) for app control and per-zone scheduling. Works with the Trench’s standard valve fitting.
Fan controls (Clima & Hybrid Canal)
Clima Canal (cooling) and Hybrid Canal (fan-boosted heating) versions have a small wall-mounted controller for fan speed — auto / bedroom / comfort / boost modes. Same control panel as a Jaga Strada Hybrid.
Works with your existing thermostat
Nest, Hive, Tado, or a simple programmer all work. The Trench connects to your wet-system heating like any other radiator — no special control infrastructure needed.
Auto switchover (Clima Canal)
Clima Canal models sense the water temperature and switch between heating and cooling automatically when paired with a reversible heat pump. No buttons to press in spring / autumn.
CleverBloom can help
Picking the right control setup for your model (basic TRV vs smart TRV vs fan controller) is something we work through during the design phase.
Trench convectors install during construction or major refurbishment — the recess needs to be formed in the floor as part of the build.
The only visible part of the Trench is the grille. Pick a finish that disappears into your floor or one that stands out as a feature.
Natural wood
Oak, walnut, beech, or birch grilles to match your wood floor. The grille becomes almost invisible against the surrounding planks.
Aluminium
Brushed silver, anodised black, or anodised bronze. Modern, clean, suits contemporary interiors and commercial spaces.
Brass
Polished, brushed, or aged brass. A premium finish that develops character with age. Common in high-end residential and hospitality.
Matt black
Powder-coated matt black for contemporary kitchens, dark stone floors, or industrial-style interiors. Clean modern statement.
Curved lengths
For curved glass walls, grilles can be ordered in curved sections. Made to your floor plan.
Custom RAL colours
Aluminium grilles can be powder-coated to any RAL colour for special projects — matching brand colours, an interior designer’s scheme, or a specific floor tile.
Once installed, almost nothing to maintain. The grille rolls up for easy cleaning.
30-year warranty
On the Low-H2O heat exchanger. The metal tray and pipework warranted separately. The grille itself has its own finish warranty depending on material.
Built in Belgium
Made by Jaga in Diepenbeek, Belgium. Family-owned business since 1962. Same Low-H2O technology as their wall radiators.
Roll up the grille to clean
Most Trench grilles roll up like a slatted blind — lift one end, the grille rolls out of the recess for cleaning. Vacuum inside the tray. Two minutes once or twice a year.
Bleed once a year
Like any wet-system radiator, bleed any trapped air once a year. We do it during the annual service if you have a contract with us.
Clima Canal fan service
If you have the cooling-capable Clima Canal version, the fan needs a yearly clean and the condensate drain checked. Standard part of an annual service contract.
No VAT on the install
UK government has removed VAT on heating installs until March 2027 when paired with energy-saving heat pump systems. CleverBloom handles the paperwork.
Heat pump unit only. Radiators, UFH, and emitters are on the heating page.
