The EWS26501 is more than a basic floor heating distribution manifold. It combines the main circulation, temperature regulation, monitoring, balancing and maintenance functions required in a typical hydronic underfloor heating installation.
Heated water enters the manifold through the primary side, where a thermostatic valve helps regulate the water supplied to the floor heating circuits. The integrated circulation pump then distributes water through the selected heating loops.
Each circuit can be independently adjusted to help balance water distribution according to room size, loop length and system requirements.
After circulating through the floor heating pipes, the water returns to the manifold and is directed back toward the heat source.
This integrated design helps reduce the number of separate hydraulic components required around the manifold and provides a cleaner, more organized installation.
The EWS26501 is available in configurations ranging from 1 to 16 heating loops, allowing one manifold series to serve a wide variety of residential and commercial floor heating projects.
Smaller configurations can be used for compact heating zones, while larger manifolds can distribute water across multiple rooms or areas.
HVAC distributors and project suppliers can cover different installation requirements using a standardized manifold platform instead of sourcing completely different systems for every project size.
A WILO Para 25/6 circulation pump is integrated directly into the manifold assembly.
The pump provides circulation through the hydronic heating circuits and is positioned on the front of the unit for convenient installation, inspection and servicing.
The pump is attached using studs, allowing it to remain removable and interchangeable when maintenance is required.
Integrating the circulation pump into the manifold reduces the need to design and install a completely separate pumping assembly.
This can simplify system installation while making future pump access more convenient.
The manifold incorporates a thermostatic valve with probe and capillary tube on the primary side.
The thermostatic control helps regulate the temperature of the water entering the underfloor heating circuits.
This is especially important because hydronic floor heating normally operates at lower water temperatures than many conventional radiator heating systems.
More controlled supply water temperature helps maintain suitable operating conditions for the floor heating system and supports consistent indoor comfort.
The EWS26501 includes two thermometers:
One thermometer on the supply / primary side
One thermometer on the return side
This makes it easier for installers and maintenance personnel to compare the temperature of water entering and returning from the floor heating circuits.
Monitoring supply and return temperatures can help installers evaluate whether the heating system is operating as expected and identify abnormal temperature differences during commissioning or maintenance.
Instead of relying entirely on external measuring equipment, the main system temperatures remain visible directly on the manifold.
Different floor heating circuits rarely have exactly the same pipe length, pressure loss or heating demand.
For this reason, the EWS26501 incorporates adjustable valves that allow individual heating circuits to be balanced according to system requirements.
The loop connections use adjustable and lockable valve arrangements to support more controlled water distribution.
Correct hydraulic balancing can help prevent situations where short loops receive excessive water flow while longer loops receive insufficient circulation.
This contributes to:
More even floor temperatures
Better room-to-room comfort
More stable system operation
Improved hydraulic performance
The manifold is prepared for compatible M30 × 1.5 electrothermal actuators.
When combined with suitable room thermostats, actuators and a compatible control system, individual heating loops can be opened or closed according to room temperature demand.
For example, separate manifold circuits may serve:
Living rooms
Bedrooms
Kitchens
Bathrooms
Offices
Independent heating zones
Actuator-ready connections make the manifold suitable for modern multi-zone underfloor heating systems where different rooms need independent temperature control.
An air vent is positioned at the upper section of the manifold, where air inside the hydronic system naturally tends to collect.
Depending on project requirements, the manifold can be configured with a manual or automatic air vent.
Air trapped inside a hydronic floor heating system may cause:
Circulation noise
Unstable water flow
Reduced heat transfer
Uneven heating
Difficult commissioning
Integrated air venting therefore helps simplify system commissioning and ongoing maintenance.
A drain valve is incorporated into the manifold assembly.
It can help installers perform common system procedures including:
Initial system filling
System flushing
Commissioning
Water drainage
Routine servicing
Maintenance work
Integrating the drain connection reduces the need to add another separate drainage component around the manifold installation.
The EWS26501 uses powder-coated steel profiles with structural dimensions including:
50 × 50 × 2 mm
and
50 × 80 × 2 mm
Standard surface finishes include:
RAL9005 – Black
RAL9010 – White
The powder-coated surface provides a clean appearance while helping protect the steel structure during normal indoor HVAC installation and use.
Depending on the selected configuration, the EWS26501 manifold system incorporates the primary components required for hydronic floor heating distribution.
Standard configuration includes:
Provides circulation through the floor heating circuits.
Provides additional system protection.
Installed at the upper section of the manifold to assist with air removal.
Displays the temperature of water entering the heating distribution system.
Displays return water temperature.
Helps regulate supply water temperature.

A hydronic underfloor heating manifold acts as the central distribution point between the heat source and individual floor heating circuits.
The typical process is:
Heat Source
↓
Supply Water Enters the Manifold
↓
Thermostatic Temperature Regulation
↓
WILO Circulation Pump
↓
Water Distributed to Individual Heating Loops
↓
Heat Transferred Through Floor Heating Pipes
↓
Return Water Enters the Manifold
↓
Water Returns to the Heating System
The manifold allows several floor heating circuits to operate from a centralized distribution point while giving installers access to temperature monitoring, hydraulic adjustment and maintenance functions.
The EWS26501 is suitable for hydronic floor heating systems used in:
Apartments
Houses
Villas
Townhouses
Multi-room residential properties
Different loops can be assigned to different rooms or heating areas.
The manifold can also be incorporated into properly designed commercial hydronic heating systems for:
Offices
Hotels
Retail spaces
Showrooms
Commercial buildings
Public facilities
The availability of up to 16 heating loops makes it suitable for projects requiring multiple heating zones.
For properties requiring independent heating circuits, individual manifold loops can distribute water to different rooms or zones.
Combined with compatible thermostats and actuators, the system can support room-by-room temperature management.
The manifold can form part of a hydronic floor heating system supplied by a compatible boiler.
Its thermostatic control arrangement helps manage the lower supply temperatures typically required by floor heating circuits.
Hydronic underfloor heating is frequently used with low-temperature heat sources.
The EWS26501 can be incorporated into compatible heat pump floor heating systems where the manifold specifications, pump performance and hydraulic design meet the project requirements.
A conventional installation may require the installer to separately source and assemble:
pump, temperature control valve, thermometers, air vent, drain valve and manifold control components.
The EWS26501 combines these functions into one integrated assembly.
Using an integrated manifold can simplify component selection because many of the main hydraulic functions are already incorporated into the system.
Pre-integrated components can reduce the amount of on-site assembly compared with constructing the complete manifold station from separate parts.
The front-mounted pump, visible thermometers, air vent and drainage components provide installers with straightforward access to key system functions.
With 1 to 16 loop configurations, the manifold can be adapted to different building sizes and heating-zone layouts.

The required number of manifold circuits depends primarily on the floor heating system design rather than simply the total building area.
Important factors include:
Rooms requiring independent temperature control generally require separate heating circuits.
Long floor heating pipe runs may need to be divided into multiple circuits.
For the EWS26501, the recommended maximum pipe length is approximately 100 meters per loop.
Larger rooms or areas with higher heating demand may require more than one circuit.
Pipe diameter, circuit length, fittings and system layout all influence pressure loss and pump requirements.
For large or complex projects, manifold size should be confirmed according to the heating design rather than selected only by room count.
