What is a Mobile Heating Manifold?
A mobile heating manifold is a transportable unit used in temporary heating systems to distribute the heat generated by a mobile heating plant to various heating circuits. They are essential for creating a controlled, temporary heat supply.
What are Mobile Heating Manifolds Used For?
Mobile heating manifolds are used in various scenarios where a temporary and flexible heat supply is required. The most common areas of application include:
Construction Heating and Screed Drying
In new buildings or during renovations where the permanently installed heating system is not yet operational, mobile heating plants are used for drying screed or for providing construction heat. A mobile heating manifold ensures the standard-compliant and controlled heating of the underfloor heating circuits.
Emergency Heating
In the event of a failure of the primary heating system, for example due to a technical defect or during renovation work, mobile heating manifolds, in conjunction with a mobile heating plant, ensure a fast and reliable emergency supply.
Event Heating
For events in tents or temporary structures, mobile heating systems are used for heating and hot water preparation. The manifold enables targeted heat supply to different areas.
District Heating Supply
For the temporary bridging of maintenance or repair work on the district heating network.
How Does a Mobile Heating Manifold Work?
The function of a mobile heating manifold is identical to that of a permanently installed manifold, although it is designed for mobile use. The process can be described as follows:
- Connection to the Mobile Heating Plant: A mobile heating plant (e.g., a mobile heater on a trailer or a heating container) generates hot water. This water is transported to the mobile heating manifold via flexible, insulated hose lines.
- Distribution of the Heating Water: The manifold consists of a flow and a return bar. The flow bar receives the hot water from the heating plant and distributes it to the connected heating circuits (e.g., the individual loops of an underfloor heating system).
- Regulation of the Flow Rate: Each heating circuit on the manifold is equipped with valves and often with flow meters (top meters). These enable hydraulic balancing, in which the flow rate for each individual heating circuit is precisely set. This is necessary to ensure uniform heat distribution, as the individual heating circuits are often of different lengths and thus have different pressure losses.
- Control of the Room Temperature: Actuators are usually mounted on the manifold’s valves. These are controlled by room thermostats. If a room thermostat reports that the desired temperature has not yet been reached, the actuator opens the valve for the corresponding heating circuit, and hot water flows through. When the target temperature is reached, the valve closes.
- Return of the Cooled Water: After the water has released its heat into the room, it flows as cooled water via the return bar of the manifold back to the mobile heating plant, where it is reheated.
Modern mobile heating solutions often feature digital remote monitoring, which makes it possible to monitor operating data such as boiler temperature, water pressure, and tank level via computer or smartphone.
What Types of Mobile Heating Manifolds are Available?
Mobile heating manifolds are part of an overall system. The actual distinction lies in the type of mobile heating plant that generates the heat. These can be categorized as follows:
| Type | Description | Power Range | Fuel/Energy Source | Typical Applications |
|---|---|---|---|---|
| HEATING PLANT IN A TRAILER | Compact heating plants mounted on a car trailer; very flexible and quick to deploy | 50 kW – 950 kW | Heating oil, natural gas, liquid gas | Emergency heating, screed drying, smaller construction projects |
| HEATING CONTAINER | Heating systems built into robust ISO containers (5, 10, or 20 feet); suitable for high outputs and longer rental periods | 350 kW – 2,500 kW | Heating oil, natural gas, liquid gas | Large construction projects, district heating bridging, industry |
| ELECTRIC HEATING PLANTS | Compact, mobile devices powered by electricity; emission-free at the point of use | 21 kW – 36 kW | Electricity | Smaller renovations, water damage drying, use in water protection areas |
| MOBILE HEAT PUMPS | Use ambient heat for heat generation; environmentally friendly alternative | approx. 100 kW | Electricity | Projects focusing on sustainability, low-temperature applications |
