A floor heating manifold ensures the correct distribution of hot water across the various groups in your home or business premises. A good manifold regulates the flow and temperature, allowing your floor heating system to heat efficiently and evenly. At viawww.nl you will find an extensive range of manifolds from renowned brands such as Uponor , Robot , Rehau and Henco . Below we explain the most important differences and properties, so that you can find the perfect match for your project.

1. Uponor: Komfort and Minitec systems

Uponor Komfort (1 – 15 groups)

• A robust, versatile distributor for both small and large installations.
• Available in different group sizes (from 1 to 15), so you can tailor it exactly to the desired capacity.
• Made of high quality materials that are resistant to corrosion, for long life and reliable operation.

Uponor Minitec

• Specially designed for renovation and situations with minimal installation height.
• Wet construction system: the pipes are laid in a thin layer (approx. 1 cm) on the existing floor, after which the finishing floor is applied.
• Ideal if you want to add underfloor heating without major adjustments to the construction.
• Combine Minitec with an Uponor manifold (such as the Komfort series) for optimal results.

2. Robot: extensive range for every application

Steel distributor (without pump)

• Made of sturdy steel, suitable for simple applications.
• Without pump: you connect this distributor directly to the heating system or use an external pump.

Composite distributor (with/without pump)

• Lightweight and corrosion-resistant material, ideal for homes with higher humidity or for those who want to avoid rust formation.
• Available with built-in pump (for a ready-to-use solution) or without pump (if you already have a suitable pump).

Standard/Optimum Flow Distributor Pro (with Wilo Para pump)

• Equipped with an energy-efficient Wilo Para pump.
• “Optimum Flow” technology for automatic or easily adjustable flow per group, which makes balancing faster and more precise.

City distributor

• Specially developed for district or block heating, where higher or different pressure and temperature conditions often apply.
• May include an integrated pump and control system depending on model.

Stainless Steel Distributor

• Stainless steel (stainless steel) is strong, hygienic and corrosion resistant; an excellent choice for durable installations.
• Often used in projects where long life and minimal chance of rust are absolute priorities.

LTC composite manifold

• LTC stands for “Low Temperature Circuit”; suitable for installations where the water temperature is kept low.
• Composite material: lightweight, durable and corrosion resistant.

LT distributor without pump / LTV distributor with Wilo pump

• LT: a low-temperature distributor without a pump, suitable for systems where the boiler or heat pump already has a circulation pump.
• LTV: the same low-temperature functionality but with an integrated, energy-efficient Wilo pump.

Robot clamp ring and clamp ring set / Robot (repair) couplings

• Useful accessories and replacement parts so that you can make or repair pipe connections safely and leak-free.
• Compatible with most Robot distributors and often universally applicable for similar sizes.

Robot control/pumps

• Individual controls, pumps and accessories to upgrade or replace your existing distributor.

3. Rehau: 3001 ESP d v2a & Speed ​​distributors

3001 ESP d v2a

• A high quality stainless steel (v2a) distributor with a focus on robustness and reliable sealing .
• Suitable for different pipe diameters and number of groups, depending on the configuration.
• ESP d technology guarantees smooth water flow and easy adjustment.

Rehau Speed ​​distributors

• Developed for quick and easy installation, ideal for installers who often deal with changing projects.
• Ergonomic design and clear markings per group, which reduces the chance of errors during assembly.
• Here too you benefit from Rehau's quality in terms of material selection and corrosion resistance.

4. Henco Floor: versatile distributors for every floor

Henco Floor Distributor

• The Henco catalogue shows that these manifolds are suitable for both small domestic installations and larger commercial projects.
• Compatible with the well-known Henco multilayer pipes, so you benefit from a complete system that is perfectly matched.
• Available in various group quantities and versions (e.g. with pump, without pump, in stainless steel or composite), depending on your specific requirements.

What should you pay attention to when choosing a distributor?

1. Number of groups
   • How many rooms or zones do you want to heat? Choose a distributor with sufficient groups (and possibly a reserve group if you want to expand later).
2. Material
   • Steel, stainless steel or composite: each material has its own advantages in terms of price, lifespan and corrosion resistance.
3. With or without pump
   • If you already have a pump in your boiler or heat pump, a distributor without a pump will suffice. Otherwise, a distributor with a built-in pump can be useful.
4. Low vs. high temperature
   • Some manifolds (LTC/LT types) are specifically designed for low temperature heating, ideal for heat pumps.
5. Adjustment and operation
   • Some models (such as Robot Optimum Flow) are pre-adjustable or equipped with automatic flow controls, which provide precise adjustment and can save energy.
