Trench Heaters
What is a Trench Heater?
A trench heater is like a water-based radiator placed under the floor instead of taking space up on the wall and in the room. It includes an inner hot pipe with fins providing convective heating to the surrounding air which then rises and heats up the room. Trench heaters are available as 2-pipe solution which make them ideal as primary heat source but work also well as secondary heating assisting in eliminating downdrafts from large glass facades. Alternatively, a 4-pipe solution is available on the market allowing altering heating or cooling depending on room occupancy and outdoor weather. All together trench heating will result in increased floor space without compromising human comfort.
Trench heating is common in cubicles, hotels, restaurants or any other modern commercial buildings.
How is a Trench Heater Application Optimized?
With proper balance, a trench heater or a trench combi-unit may reduce heating or heating/cooling costs by up to 20% while protecting the indoor climate and increasing people comfort. FlowCon recommends three different solutions to a trench heater installation:
1. Trench Heaters with Pressure Independent Control (PICV)
The PICV will react to system pressure changes and regulate the flow of water to required flow by adjusting the actuator position. This helps the system to be accurately controlled even with pressure changes and reduced loads.

FlowCon recommends the following PICVs:
2. Trench Heaters with Temperature Control (TCV)
The TCV will react to system pressure changes and automatically provide the selected max. flow independent of pressure changes. In addition, the actuator will provide ON/OFF control, securing proper thermal performance always, even at partial loads.

3. Trench Heaters with Automatic Balancing (ABV)
The automatic balancing valve will react to system pressure changes and limit the flow of hot or cold water to required max. flow helping the system to be accurately controlled even with pressure changes.
